Jerry the ginseng that is project builds each to just be jumping-off place with oneself economy interest, adopt reduce project quality level, disobey engineering construction quality to check and accept a standard, escape quality supervises the action that checks and accept a program, saying on firm sense is a kind of illegal behavior.
1, basically involve 3 related sides:
Build square: To reduce project cost requirement designs the data that square, construction just is adopted or uses inferior quality, component to wait undertake design and construction.
Construction unit (include total package, cent bag, team and group) : Material quality asks under design and standard, construction process does not check and accept a standard to undertake construction by construction craft standard and quality.
Supervisory unit: Nonperformance supervisory duty, lax case is carried out check and accept a program to wait.
Always contract the person that the organizer that the unit is engineering construction, direct canal accuses, it is project quality control most the core, most crucial principal part, should be in prevent project jerry on play dominant action.
2, the immediate cause that causes off quality and prime cause
2, common jerry what form to have?
1, project of reinforcing steel bar
1) colligation of reinforcing steel bar is too rare, jump bind, leakage is bound, leakage of muscle of special bridge heart is bound.
2) frame column and bridge have sex of place add close band to often can put 1 ～ less 2, some band outside having only and not inside band.
3) reinforcement of outfit of uneasiness of reinforcing steel bar, add muscle.
4) covering layer space block is put less or place do not accord with a requirement, especially bridge bottom.
▲ post shows muscle
▲ board bottom shows muscle
▲ bridge bottom shows muscle
5) raw material of reinforcing steel bar not cut crew cut, effective silk buckles straight threaded coupling several inadequacy.
6) use " thin body reinforcing steel bar " , dish a rate of drawing of reinforcing steel bar exceed normative requirement (Guang Yuangang veins that stand out is cold pull ratio is unfavorable be more than 4% ,
2, pattern plate project
1) short of of standard of ply of pattern plate, Mu Fang, dimension, quality asks, steel tube buckles a ply too thin, rustily and serious.
2) raise mould bases to be not set sweep the floor lever, stand, rail span is too big, prevent slippery insurance to buckle did not buckle, upside does not set freely level staff.
Prevent slippery insurance to buckle did not buckle; Establish the end on lever to extend length of lever of level carrying a layer on the head to exceed normative requirement.
3) significant step is not taken when pattern plate flat-fell seam is too big, and shot-off of loss of use snakeskin bag.
4) do not carry out by plan to pulling screw span.
5) pattern plate consolidate does not reach the designated position, cause run model, bilge model.
6) before column wall seals a model, bottom and inattentive concrete, curium wooden ash, sundry wait to did not clear clean; Bridge bottom curiums wooden ash, sundry wait not to clear.
7) Tong grade differs bigger Liang Zhu connect need not steel wire undertake barring block up or barring blocking up not firm.
3, concrete project
1) commodity concrete coordinates on the low side of parameter of the cement in comparing.
2) irrigating before building Tong not wet pattern plate.
3) concrete enters pump, irrigate water is added in building a course.
4) concrete is irrigated when building depressed pound, leakage brace up pound, optional brace up pound.
5) floor did not undertake 2 times wiping a face, do not receive light, do not water conserve or conserve time are insufficient.
6) construction is seamed do not certain wool, be like, column wall construction is seamed place did not keep clear of oar of inattentive concrete, float.
7) the hole is in condole such as roofing, toilet was not divided second irrigate build, easy cause leakage.
Wool of chisel of ① , hole;
Grout of element of ② , circumjacent rinse;
③ , cent second pouring tall the fine stone Tong of one class intensity, control of ply of first time Tong is in board 1/2 of thick 1/3 ～ is in and pound with club of reinforcing steel bar beat is close-grained, the 2nd times Tong is irrigated come to be in processing receiving light from board mouth,
Waterproof of ④ , reoccupy undertakes be handlinged (a building elevation 50mm comes instead on tubal edge, 200mm of the 150 ～ side circumjacent unkennel) , do the test that shut water.
8) Tong is irrigated when building, without reinforcing steel bar labour, carpentry is on duty, run, nobody handle cruel model.
9) hind irrigate belt irrigate when building, do not certain wool, do not clear, not pump water, not conserve.
4, project of body of build by laying bricks or stones
1) age of bigger, conserve is not worth block dimension deviation, quality does not accord with a requirement.
2) block does not shift to an earlier date wet water, build by laying bricks or stones strikes the wall on the brick when body construction.
3) mortar is not full.
4) the length of solid of establish muscle anchor that body of build by laying bricks or stones pulls knot muscle is insufficient, become loose.
5) two side do not press hole of tectonic column, construction normative requirement places the muscle that help a tie.
▲ does not have the muscle that help a tie
▲ already installed the muscle that help a tie
6) Tong of tectonic capital ministry is irrigated build not close-grained.
5, plasterer Cheng
1) before plasterer, body of qualitative wall of different capable person has sex place, leakage hangs a net.
2) plasterer was not done protect the horn, amount that make cake too little, when plasterer survive, plasterer hind did not undertake conserve.
6, waterproof project
1) waterproof introduces the product that be not mark, be like a material ply to wait for index not to amount to mark not quite.
2) processing of layer of waterproof construction time base does not reach the designated position, be like not solid, clear sordid; Horn of yin and yang did not make circular arc part, do not do waterproof and add layer.
Detail of waterproof basic level
▲ Tong waterproof basic level solid, clean, level off, press light, without case arenaceous
Roll the place such as the horn of yin and yang in waterproof facing basic level should do capable person circular arc. Circular arc diameter asks: Bitumen is waterproof a material 200 ～ 300mm, bitumen of high polymer modified is waterproof a material 100mm, synthetic high polymer is waterproof a material 40mm.
Roll the place such as the horn of yin and yang in waterproof facing basic level should do capable person circular arc. Circular arc diameter asks: Bitumen is waterproof a material 200 ～ 300mm, bitumen of high polymer modified is waterproof a material 100mm, synthetic high polymer is waterproof a material 40mm.
3) roll material is built receive not close, receive a head not to accord with a requirement.
Roll material presses wall body groove inside, with layering hammer pressing is secured and use sealed data sealed rigor, roofing of sunken slot pitch finishs face height not less than 250mm, body of groove upside wall does waterproof processing.
7, other material
Level of state of short of of material of semi-manufactured goods, finished product asks, often say namely " blame mark " product, if baluster uses the adornment data such as the thickness that stainless steel provides, ceramic tile, a lot of minutes of bags rely on to take the place of in order to differ actor, shoddy come, earn profit.
3, measure of jerry prevention and cure
1, system of strict acceptance of materials, be on guard cent bag relies on to take the place of in order to differ actor, shoddy earn price difference.
2, beforehand does good tell sb one's real intentions, content of tell sb one's real intentions should but standard of operation, clear technological process and quality check and accept a standard. The share that frequency of common fault of more complex to working procedure, quality sends, must example leads a way.
3, want in the process diligent check and examination.
4, after working procedure is finished, want to check and accept a program strictly.
5, the quality issue that sends to frequency should have punishment, repair measure. The work group to refuse to mend one's ways despite of repeated admonition, Shang Yingqing that distribute a packet is exited.
