can be used over long teeth

How long can mend teeth?

We know that the teeth rotten hole on the back as soon as possible to the hospital for treatment (fillings). Dental health supplement can be used exactly how long, this is the most concerned about the patient, but also a more complicated issue. Teeth repaired after a short period, and how the function, with a variety of factors. denture teeth The first is timing fillings, ie when the patient visits the extent of dental caries. Location and shape of cavities have a great relationship. Followed by the filling materials, different materials and the bond of cavities vary. Furthermore, that dental cavities before processing. If only carious cavities and the cavity is good, shallow, and not adjacent surfaces of teeth, etc., are only required to clean and remove tooth decay cave organize, prepare cavity, thorough disinfection, with permanent dental materials the cavities were filled. Such a good complement of teeth should be used for life. When the dental pulp or apical lesions reached, as long as thoroughly anti-inflammatory treatment, and finally achieve tight filling, but also can be lifelong. But if severely damaged teeth, tooth hole is too large, too deep, irregular shape, or proximal hole type, then filled with good teeth should be used with caution. Otherwise, biting hard objects prone to splitting or dental fillings fall off. Especially kills nerve or pulp necrosis teeth without a blood supply, the teeth become brittle, so anti-inflammatory teeth after filling, biting hard objects it more likely to cause tooth splitting, filling off, resulting filling failure; even teeth completely split split into the following gums, often leading to tooth extraction. Thus, the success of the dental patient and doctor relationship dental instruments between the two are very closely related. First, the doctor fillings should be strictly and carefully press the formal procedures to operate, and the patient should also be early detection and early dental treatment, filling a good fight in the early carious teeth, to achieve the best results.

toothache types and treatment

As the saying goes: "toothache is not a disease, pain up to life," there are many manifestations toothache
1, hot and cold sweet and sour pain: sweet tooth pain cold case, removal of irritants, the pain disappeared. Dental pigmentation, common to dental caries. Gingival margin tooth surface, no pigmentation, deep wedge-shaped defect. Two kinds of dental problems are mild, restorative treatment can improve. But if it is due to gingival recession caused by dentin hypersensitivity, the treatment process is more complicated.
2, spontaneous pain: spontaneous gingival pain, can not be located, the pain got worse when sleeping; cold, curing light heat stimulation can induce pain, remove the pain stimulus continues for some time, pain to the ear temporal radiation, which means that there is inflammation of the pulp.
3, persistent pain: persistent pain in the gums, can be clearly positioned teeth floating sensation, knocking teeth or bite things obvious pain. Description invade apical inflammation. Treatment is too much trouble, emergency principle is "decompression and drainage" - to open a hole in the middle of the tooth, so inflammatory secretions out, reducing the pressure of the pulp cavity. X-rays taken after the election according to the condition of root canal treatment or plasticizing treatment.
4, biting hard objects pain: pain biting hard things have knock history of stones and other hard objects. Tooth may have cracks, severe tooth may crack. Depending on the depth of treatment decisions cracked: If tooth is loose, you want to unplug. Such as shallow, you can do sets crown retained.
5, "best-rooted teeth" pain: do-rooted teeth (wisdom tooth, third molar) at the persistent pain, Apex Locator touch gum pain got worse, with severe mouth ox, often made inflammation, anti-inflammatory after the removal of "best-rooted teeth." .
6, gum pain: persistent pain in the teeth, accompanied by swelling, loose, many accompanied by food impaction symptoms of periodontitis performance.
 
  These symptoms should be treated early, while painkillers to ease the pain.

What is the "six old tooth"? Any protection "six old tooth

1 What is the "six old tooth"? Any protection "six old tooth"?
What is the "six old tooth"? Any protection "six old tooth"? In primary molars behind the first permanent molars, since the eruption in children six years old or so, so called it "age six teeth." Just eruption of the "six old tooth" is not very strong, but without the occlusal surface of uneven wear, fissure deep, easy accumulation of food debris and plaque, and difficult to clean, so they are subject to the erosion of acid-producing bacteria, is prone to caries. We can use methods fissure in before the occurrence of dental caries, Tim flat occlusal surface deep fissure, dental material the accumulation of food debris and plaque is not easy to achieve the effect of prevention of dental caries. In addition, the "six old tooth" eruption early, but also quietly last a long in the rear molars, are often mistaken for teeth, dental caries early did not receive timely treatment, until the pain, we have very serious damage from even a teenager would have to be unplugged regret for life. To avoid this situation, you should bring the child to the hospital for checkups regularly. When the judgment is deciduous or permanent teeth can not be a problem, you should go to the hospital for a doctor to help solve the problem.

children dentition duration "double tooth" how to do

2 children dentition duration "double tooth" how to do?
Length of time the child dentition "double tooth" how to do? The tooth replacement, permanent teeth have erupted and no normal shedding of deciduous teeth, there will be "double tooth" situation. "Double tooth" phenomenon is most common in the lower front dental material teeth replaced. In the absence of the normal shedding of deciduous occupy permanent positions, a new eruption of permanent teeth can not be ranked in the normal position of the dentition, often in the lingual dentition, resulting in tooth malalignment. At this point, should be promptly removed without the normal shedding of deciduous teeth, eruption of the permanent teeth with the power to go back dentition.

Orthodontics, then of course the younger effects out faster the lower the degree of recurrence, 16 years old can also be fairly active bone remodeling, in general, across the line will be improved after orthodontic, do not worry.
If more severe congestion may require removal of some of the teeth, aligned it'll be better looked after, if you still feel bad teeth appearance can do porcelain teeth, but most of the dentition will not affect the development of dental morphology, but it feels awkward position is not normal.
Orthodontics is generally considered full mouth, and how have 5,000 or more, on the one hand your personal requirements to what kind of effect, then there is the complexity of the tooth with you. Generally do not need to pay a one-time fee of Qi, orthodontics is a long process that requires regular follow.
Before making orthodontic curing light periodontal maintenance, handle dental caries. Basically that's all

dental treatment new ideas - loose teeth can be retained

Loose teeth is not only pulled? Oral famous medical experts cattle Dongping chief physician has given this a negative answer. In the recently held a press release

At the meeting, cattle Dongping presents new ideas for dental treatment: try to keep loose tooth or root, and the use of a "rigid support theory" production "rigid support

Type of denture. "
Due to periodontitis and other causes of loose teeth, many doctors think we should pull loose teeth, the patient generally accept. Cattle Dongping think, teeth and root

Will cause the loss of a dental material series of changes jaw. For example, loss of teeth, it will lose the periodontal ligament passes through the root of the tooth to the alveolar force, and this continued

Regular physiological stimuli, can promote blood circulation in the jaw, to maintain the normal physiological state, and alveolar bone metabolism, prevent alveolar bone absorption and shrinkage,

To maintain its proper height, width and fullness, which denture support, retention and stability play an important role. Clinical cattle Dongping also found that even if the root

Without any treatment, it also prevents the persistence of jaw atrophy.
In addition, keep loose teeth or roots, it retains the periodontal ligament and proprioceptive nerve endings. When conducting functional occlusal tooth when the body of the periodontal ligament

Receptors sense the size and direction of occlusal force, so that occlusal force maintained within the physiological range, which is very important for the protection of the abutments.
Cattle Dongping scientific literature in a foreign country found a "rigid support theory", put this theory into practice, made of "rigid-supported denture."

After ten years of clinical trial and error, cattle East peace his colleagues thousands of advanced periodontitis patients subjected to preserve and utilize loose teeth cure, with

When the production process and technology continue to be refined, and achieved satisfactory results.

teeth reveal numerology

Physiognomy is a traditional Chinese five patients in a science, mainly from the human face or body characteristics, behavior, etc. to determine a person's character and health, thereby pushing

Measuring a person's <A destiny. Since ancient times, people have a certain dental concerns and requirements of the natural physiognomy scope of the study also included an articulate. So different teeth against

How different it swayed dental products ? Let's hear how professional tellers say.
 A, blackish yellow or skew teeth missing persons </ B> are generally present health issues, academic and marriage are not very good, is the relative poverty, there are also others harm g

The track.

 Two front teeth crooked or defect fate of the majority and shallow parents or childhood affection has some shadow on the future marriage feelings have serious implications.
Third, those who are generally wary of small teeth stronger person. These people is not easy to trust others, and their jealousy is very strong, easy to stir up trouble because of some trivial.

 Four, incisors larger </ B>, instructions physical strength, energy up, libido strong.
Fifth, there is a gap teeth will not only air leakage, but also financial drain. Therefore, there is gap incisors people with both parents love is thin, but also a noticeable lack of build wealth.
 Six, who face a small but big teeth, this is no fortune, no longer, no love luck physiognomy.
Seven, but all uneven teeth usually very irritable temperament, personality is impulsive type, even if it is with a partner can not live in harmony.

 Eight, canine personality type who would be more violent, not only easy to provoke the crisis, the most important is the natural look of even bankruptcy phase, which was humble person's face.
 Nine, buck teeth who are relatively superficial mind, easy to speak without the mind who offend people is common. And respect is quite stubborn character.
Ten, if people in the prime of life falling teeth, indicating that this life to be very physical exertion, and life will not last long.
 Eleven, teeth solid and dense solid people generally live longer, and there is a delicious food of the people.
 Clear from the neat white teeth natural symbol of wealth and lucky, but in reality not everyone has a good natural teeth, so to say, dental mouth bad people fortune

Would not necessarily bad? Of course, not exactly. Themselves are extremely complex and sophisticated creatures, should also be based on natural whole fortune to judge.
 But the phrase "the phase from the heart," a person's face and body with a little inner emotions is actually true performance, if a person has a perfect facial features,

She is also impeccable, but day be unhappy, dental equipments preoccupied, physiognomy certainly would not be the bright shine on people. Conversely, poor external image will naturally on the parties

Adverse impact on people's emotions.
 As social etiquette, in addition to decent manners, the reasonable dress and the same good looks will naturally help you win more and better opportunities and friends. But if your

Unsightly teeth, not only your appearance big discount, and likely facing a crisis in the business world, self-confidence will be affected, so a vicious cycle, natural fortune

the financial crisis on the impact of the medical device industry

The current global financial crisis facing the financial crisis is not over the past 100 years occurred in the most serious financial crisis, the financial market crisis led recession

At present, China's medical device industry although there is a gap compared with developed countries, High Speed Handpiece but the pace of development of China's medical device makes the world look askance. China's most

Research and development of new medical device products also walk in the international medical device industry tip. Within the next few years, China will surpass Japan to become the world's second largest medical device market

Field.

With the development of domestic enterprises, the rapid increase in strength, and market focus shifted from high-tech to the universal, the competitiveness of domestic products is gradually increased, the domestic

Companies expand market offers a rare opportunity. Foreseeable future, China's medical device industry is a huge space for development.

In addition, the worsening financial crisis in the world in the context of the international economic environment, to resist the negative impact on China, November 5, 2008 regular meeting of the State Council

there are two types of type

 First, the primary co-traumatic primary occlusal trauma
Where due to abnormal or excessive force factor, so that normal periodontal tissue damage, known as primary co trauma. Primary occlusal plane periodontal tissue injury is normal, but the bite force is excessive or abnormal occlusal direction, more than the normal periodontal tissue can withstand the load.
Second, the secondary co-traumatic secondary occlusal trauma
Because periodontitis and other reasons, the lack of supportive periodontal tissue itself, incapable of normal or excessive bite force, so that further damage periodontal tissue called secondary trauma together.
Bite wounds are secondary station is due to other causes periodontitis periodontal tissue support strong High Speed Handpiece enough that periodontal tissue's ability to withstand December force weakened, in this case the normal or abnormal bite can lead to bite Taiwan of trauma.
Some scholars have proposed acute occlusal trauma (acute trauma from occlusion) and chronic traumatic occlusion (chronic trauma from occlusion). Acute emergencies caused by occlusal trauma refers to excessive occlusal forces (such as chewing hard objects) caused by periodontal trauma. And chronic traumatic occlusion refers to sustained abnormal bite force caused by periodontal tissue damage.

occlusal examination and occlusal trauma index

1. Check the occlusion
Occlusal examination of patients include: (1) the middle jaw, between the middle jaw, jaw type, the upper and lower dental midline, overlying coverage and other jaw. (2) crowded teeth, twist, shift, partial occlusion disorders. (3) early contact and occlusal interference. Including protrusion posterior and lateral contact with non-working side contacts. (4) The doctor will forefinger on the patient buccal maxillary teeth, so that patients do occlusal movements, tremor teeth, also known as functional tooth mobility.
2. Occlusal trauma to testify
Common to testify include: persistent occlusion discomfort, loose teeth, shift, when the teeth bite tremor and X ray film wedge gap widened periodontal ligament and bone hard board blurred or disappeared. In general, no single unique performance occlusal trauma. dental instruments Currently many scholars believe that the continued increase in tooth mobility and occlusal tooth tremor when checking out a relatively reliable and common result.
Periodontal occlusal trauma index (trauma from occlusion index, TOI): Functional increased tooth mobility + gap widened periodontal ligament.
Periodontal adaptation index (adaptability index, AI): tooth surface wear + bone hard board has widened.
TOI positively correlated with the extent of periodontal destruction, AI negatively correlated with the extent of periodontal destruction.

yellow teeth how to do

 Yellow teeth seriously troubled people's work and life, especially to people's lives communicative disorders, many people because of yellow teeth without changing laugh, do not even want more

Speak, then yellow teeth how to do it, today we have come to learn more about this topic.


    Yellow teeth how to do? Experts pointed out: yellow teeth caused by a variety of reasons for yellow teeth treatment measures, should identify the cause of differentiation therapy.


    Here we have yellow teeth to a detailed understanding of the cause. First, the water quality factors: dental Vacuum Former in some areas, especially in some mountainous areas, since high levels of fluoride in water, too much

Drinking fluoride teeth will be yellow, but big mouthful of yellow teeth. Second, poor health habits can also lead to the occurrence of dental Fadian: Some people do not pay attention to oral hygiene, no brushing

Habits, tooth surface accumulation layer food scraps, debris, calculus, smoke stains, tea stains. In addition, the teeth during development because poor nutrition or been ill, will

Calcification of the teeth affected teeth will yellow and crisp.


    Yellow teeth, there are many reasons, such as drug problems can also lead to the occurrence of yellow teeth, yellow teeth, then how to do it? Experts pointed out that dental clinic,

For yellow teeth there are many ways, such as tooth bleaching, whitening, veneers, porcelain teeth, are a good teeth whitening methods, he may allow patients in a short period dental Endo Box Goodbye to yellow teeth, with a white white teeth.

gingival recession What harm

 Gingival recession is a common disease in dentistry, dental health hazard gingival recession. Well, what harm gingival recession? When gums shrink after aging for teeth

Alveolar bone declining ability to transport nutrients and alveolar bone atrophy along with it shorter, oral medicine called "resorption phenomenon."
Gingival recession led to this "micro-joints" package to maintain strength reduction, teeth began to loosen, dental material and alveolar bone is absorbed, shallow roots of the teeth, dental

Teeth longer, with the growing phenomenon of increased bone resorption, teeth naturally fall off.


       Gingival recession also led to root exposure (dentin part), no enamel surface of teeth, gums if there is no protection, not only easy when brushing

Subject to wear, while the cold, heat, acid stimulation is very sensitive to oral medicine called "dentin hypersensitivity", people often mistaken for this phenomenon is exposed tooth nerve conduction

Cause pain, which is wrong.

no brackets invisible braces

Missing teeth bite can be used without brackets invisible corrective surgery to repair without brackets invisible surgery allows patients in the beautiful and comfortable succeed in straightening teeth. No brackets invisible braces are innovative stereoscopic 3D computer technology, tailored to a range of nearly imperceptible transparent denture to complete the entire orthodontic treatment. No invisible orthodontic bracket orthodontic parts that require applying a corresponding pressure on the site of deformity under pressure in a long time slowly move to the correct position. Various malformations, different expected results, correct the installation to be used in different ways. Whether due to crowded teeth, there is a gap, orthodontics wire displaced teeth after conventional treatment, absolutely can regain smile. [1]
No bracket has two straightening teeth surgery advantages:
1, convenient: dental panoramic head measuring instrument accurately measured and calculated data misplaced teeth, one-time modeling, invisible braces can bring their own use at home, eliminating the pain of frequent referral.
2, invisible braces: braces are transparent, direct stuck deformity teeth, misaligned teeth quietly changed.

bionic beauty crown correction

The situation is different occlusal dislocation, resulting in varying degrees of facial appearance and dental function disorders, timely orthodontics is the key, to choose their own method can effectively improve the speed of orthodontics. Nano-bionics beauty crown can precisely adjust the upper and lower teeth occlusion. It is more integrated into the bionic design concept, the focus on dental aesthetics more emphasis on the premise of natural tooth structure, complete, and highly compatible with various parts of the mouth, the use of environmental dental supply companies health absolutely no toxic residue of the material, shaping and real teeth as excellent Mechanical properties of chewing teeth. Is misplaced by hundreds of thousands of European and American teeth, dental deformity in patients has been recognized professional repair tools, compared with traditional methods, nano bionic beauty crown has no extractions, no pain, strong teeth, gums do not appear for years after the black line, and gums highly compatible with real teeth without second advantage.

dental machine history

Tablet press tablet press appeared in Europe earlier, there are nearly a hundred years of history. In China in 1949, Shanghai Tianxiang Hua Kee Iron Works imitation caused British 33

Punch tablet press; 1951, according to the U.S. 16-punch tablet machine converted into a domestic 18-punch tablet machine, which is the earliest domestic manufacturing pharmaceutical machinery; 1957, designed and manufactured

ZP25-4 type tableting machine; curing light 1960, to design and manufacture successful 60-30 type tableting machine, with automatic rotation, compression function, pressed varieties tablets, sugar tablets,

Calcium, coffee tablets. The same year also design and manufacture a type ZP33, ZP19 type tabletting machine.

dental machine development status of domestic

(1) tablet machine specifications numerous large quantities. Tableting machine, although the oldest of pharmaceutical production equipment, as well as export the earliest, the largest pharmaceutical production equipment

. Can suppress round tablets, engraved tablets, shaped tablets, double-layer tablets, multilayer tablets, ring-shaped piece, including chips and other sheet-type. Tableting machine manufacturer's number, types and specifications, production

In the world, is an indisputable fact.

(2) easy to operate. low speed handpiece In recent years tableting machine manufacturing companies starting to focus on quality of products, mostly Bong letter "quality win" business philosophy. For the domestic pharmaceutical manufacturers

Many tablets variety, small-scale production features. Tableting machine manufacturing enterprises, the development of tableting machine with a simple, clean convenient features, special

Do not be replaced varieties, cleared quickly and easily.

(3) low-tech, technological innovation after the weak. More than 40 domestic pharmaceutical production equipment more than sixty varieties and specifications tableting machine tableting machine. Although,

Every year new products are constantly introduced. But where the real level of technology and high added value of the species are few. Product duplication of development serious plagiarism

Prevalence of a variety of tablet presses up to dozens of manufacturers. To survive, many small-scale pharmaceutical equipment enterprises not only in technological innovation to take "Imitation

indications for surgery

Who needs teeth cleaning
1, the periodontal health of the population, it should be every six months to a year to a regular hospital for ultrasound cleaning teeth to prevent periodontal disease.
2, prepare baby born to women, pregnancy should be preceded by the dental hospital or general hospital dentistry, dental check the situation, according to the inspection determine the need for cleaning teeth, to ensure that pregnancy oral periodontal health.
3, with periodontal disease: bleeding, such as brushing your teeth, gums, swelling and other symptoms,dental hand piece you should always go to hospital for treatment, the doctor will be different according to each patient's condition, for cleaning teeth and some other treatments. After treatment of periodontal disease, in order to ensure the efficacy and prevention of disease recurrence, should be regular periodontal maintenance therapy, these include teeth cleaning.
Who should clean teeth
One, people suffering from acute infectious diseases, such as acute active hepatitis, tuberculosis, etc., these people should wait until stable disease only after scaling to the hospital. Scaling should be clearly informed of the illness the doctor, who should make the relevant aspects of the protection and the use of the equipment must be disinfected or discarded. On the one hand because of their illness, but also to avoid infecting others furthermore.
2, with gingival cancer patients should not receive routine dental cleaning in order to avoid local spread and distant tumor spread.
3, local oral hard and soft tissue inflammation in the acute phase patients, should be scaling again after the acute phase, in order to avoid aggravating or local inflammation spread through blood, spread.
4, with active angina, myocardial infarction within six months as well as episodes of failure to effectively control hypertension and heart failure patients should not receive routine dental cleaning treatment. Because ultrasound stimulation and discomfort when scaling, it may lead to exacerbations. If you installed the artificial heart pacemaker but not suitable for ultrasonic scaler.
5 people suffering from bleeding disorders, such as thrombocytopenia, leukemia, blood clotting mechanisms in these patients is not good, after scaling bleeding more easily.dental supply companies  Uncontrolled type 2 diabetes, after scaling as easily lead to local oral infections. For these patients, it should be pre-appropriate application of procoagulant drugs control blood clotting speed to avoid scaling when bleeding and infection.

bionic beauty crown correction

The situation is different occlusal dislocation, resulting in varying degrees of facial appearance and dental function disorders, timely orthodontics is the key, to choose their own method can effectively improve the speed of orthodontics. Nano-bionics beauty crown can precisely adjust the upper and lower teeth occlusion. It is more integrated into the bionic design concept, the focus on dental aesthetics more emphasis on the premise of natural tooth structure, complete, teeth jewelry and highly compatible with various parts of the mouth, the use of environmental health absolutely no toxic residue of the material, shaping and real teeth as excellent Mechanical properties of chewing teeth. Is misplaced by hundreds of thousands of European and American teeth, dental deformity in patients has been recognized professional repair tools, compared with traditional methods, nano bionic beauty crown has no extractions, no pain, strong teeth, gums do not appear for years after the black line, and gums highly compatible with real teeth without second advantage.

teeth invisible braces

Teeth invisible braces advantages:
1, convenient: You can pick their own wear, does not affect the social, eating, exercise and so on. While reducing the number of referral, saving you valuable time.
2 Clean: oral hygiene easier to maintain, do not worry gingivitis, tooth demineralization, dental handpiece discoloration and other issues.
3, convenient: Short and effective course of treatment, the general treatment can be completed around September to December. Traditional methods of treatment time of about 8 hours, invisible orthodontics only 3 hours.
4, appearance: almost completely invisible. You will notice it in someone else to complete orthodontics, solves many patients straightening teeth appearance concerns.
5 Comfort: Since there is no traditional sense of the bracket, steel and other orthodontic appliance Apex Locator correction process is no longer suffering. On periodontal tissue irritation and discomfort minimum. [2]

the control points

⑴ control orifice positioning error
In the above settings Secant Pile Top Construction guide wall (This project uses reinforced concrete guide wall, can also be recycled steel guide wall), the guide wall set positioning hole, the diameter should be bigger than the pile diameter 20 ~ 40mm. Rig in place, check the first one cannula inserted into the positioning hole and require the construction unit is adjusted so that the positioning around the casing to maintain a uniform gap between the holes.
⑵ urge the construction unit controls the vertical piles
According to design requirements, pile vertical deviation of not more than 3 ‰. Secant pile in order to ensure a sufficient thickness at the bottom of the amount of bite, in addition to its strict control orifice positioning errors, but also its vertical strictly controlled.
Pore-forming process to Gutta Percha Points control the verticality of the pile, you must grasp the following three aspects of the work:
① straight cannula degree examination and correction
Secant piles on flat ground before casing straight degree examination and correction, first check and correct single casing straight degrees, and then will follow the entire length of the pile sleeve configured to connect together for the entire root sheath tube (15 ~ 25m) of straight deviation should be less than 10mm. Detection method: measured on the ground emit two mutually parallel lines, the sleeve is placed between the two lines, and a line for testing the hammer and ruler.
② pile into the hole during the vertical monitoring and inspection
a ground monitoring: ground select two mutually perpendicular directions using the line hammer monitoring above-ground parts of the vertical casing, correct any deviations found. This test in each pile into the hole process should adhere to from beginning to end, can not be interrupted.
b check: After installing each section of casing pressure casing before the next section, we must stop to use the "test loop" in the hole verticality checks, failed when the need for correction, until qualified to the next section casing construction.
③ correction
Pore-forming process, such as found in vertical deviation is too large, the importance of timely corrective adjustments require the construction unit, correcting There are three common methods:
a cylinder with a rig for correction: If the deviation is not greater than or buried casing is not deep (5m less), you can directly use the rig two jacking cylinders and two sliding vertical cylinder adjustment sleeve, you can achieve the purpose of correcting .
b pile Correction: If A pile buried 5m large offset occurs below, you can first use drill cylinder direct correction, such as below standard, can be filled with sand to the casing or clay, while filling side uprooted casing, until enhance the sleeve to the last pass the inspection place, and then straighten casing, check and re-qualified under vertical pressure.
c correction: B Pile A pile corrective method is basically the same, the difference is that the casing can not be filled while filling the same with the A pile of concrete, or they may be left in the soil between piles mezzanine, thus affecting the row Pile waterproof effect.
⑶ ultra-retarding Concrete Construction Quality Control
A pile of concrete retarding time should be based on time to determine the pile into the pile, pile into the pile time and geological conditions of the construction site, pile length, pile diameter and drilling capacity factors. According to bite Piles, A pile initial setting time of T = 3t + K + Q;
Where: T - A pile of Dental Vibrator concrete retarding time t - the time required for single pile into the pile
K - reserve time, usually 1.0t Q - Night downtime
A pile general preliminary control initial setting time of 60h, the construction in the future be adjusted according to the scene.
⑷ occlusal thickness determination
Engagement between adjacent pile thickness d to select based on length of pile, pile shorter occlusal thickness is smaller, thicker pile longer bite, are calculated as follows:
2 (kl + q) ≤ d - 50mm (which is to ensure a minimum pile occlusal thickness not less than 50mm)
Where: l - pile length d - Secant Pile design occlusal thickness
k - pile verticality q - orifice positioning error tolerance

the common engineering accident prevention and treatment measures

⑴ "piping" Handling
"Piping" refers to the process B pile into the hole, because the A uncured concrete piles, still in the fluid state, A concrete pile is possible from A, B B pile into the pile hole intersection. Overcome the "piping" There are several methods:
① A pile of concrete slump should be relatively small, not more than 18cm, in order to reduce the flow of concrete;
② casing bottom nozzle should always be kept a certain distance ahead of the cutting face, in order to create a "bottleneck", to prevent the flow of concrete, if the drilling conditions permit, this distance the better, but at least not less than 2.5m;
③ necessary Gutta Percha Points (in case of underground obstacles ahead of the casing end can not) be within the casing into a certain amount of water through the water pressure to balance the pressure of concrete piles A, to stop "piping" occurs;
④ A pile into the hole process, should be observed adjacent to both sides of the top surface of the concrete pile B, B is found piles of concrete subsidence, should immediately stop A pile excavation and under the pressure side of the sleeve as far as possible, within the pile to the A side filling or water until it is completely stopped, "piping."
⑵ steel cage floating processing
Because the casing wall and the space between the outer edge of the reinforcement cage is small, in the pull casing when casing reinforcement cage may be floating along with. Preventive measures are:
① A pile of concrete aggregate size should be smaller, not larger than 20mm;
② In the bottom of the reinforcement cage welded steel cage on a slightly smaller diameter than the steel sheet to increase its anti-floating capability;
Positive reinforcement cage installation guide ③ device;
④ must follow the rules for the pouring of concrete.
⑶ drilling encountered stone processing method
If there are more venues there are rules rock band, and we will use the "two stages into a hole method" for processing: the first stage, whether A or B piles pile, first got into the rock face to the earth, and then Remove the hammer grab change from the casing with a hammer drill to punch pile design elevation, into the hole after filling the casing, unplug while filling the side casing, the first stage into a hole filled with soil full; second stage, according to the normal construction method Secant Pile Construction.
⑷ segmented construction joint approach
Often a rig construction progress of the project can not meet the need multi-rig construction segment, which exist prior construction segment joints problems. Using sand pile is a better approach in the construction segment and the segment ends to set up a sand pile (after the sand into the hole filled), subject to this section after the construction joints can be dredged sand filling the concrete.
⑸ pile handling accident
In Secant pile construction process, because B super-retarding concrete pile appeared early condensate phenomenon or mechanical equipment failures and other factors, not Secant pile construction requirements for the formation of normal accidents pile. Accidents pile handling mainly the following situations.
a pan pile unilateral occlusion
A pile into the hole construction, concrete piles B1 its side has solidified, the casing can not rig the normal requirements
 
Cutting bite B1, B2 piles. Approach is to shift the direction of the pile A pile B2 bit, make unilateral cuts B2 pile casing drilling, construction A pile (in addition to cutting the original pile guide wall, and strictly control the pile) and B1 piles and piles outside A Another increase in a rotating pile as water treatment.
b back pile reinforcement
A1 into the hole pile construction, pile it on both sides of B1, B2 are solidified concrete piles, processing methods as a waiver of A1 pile construction, pile adjustment sequence, continue to the next bite pile construction, pile outside later in the A1
 
Occlusal side increased three piles and two jet grouting pile as reinforcement.
c aside bite tongue and groove
Shown in Figure 5, the pile into the hole in the B1 A1 pile of concrete construction has been found in early coagulation tendency but not yet completely solidified, then continue as normal sequence in order to avoid accidents caused by construction piles, pile on the right timely construction of the A1 a sand pile to reserve bite tongue and groove, to be adjusted to complete before continuing behind the pile construction.
