Description
Technical field
The present invention relates to deep foundation pit support construction of diaphragm wall fields, more particularly, it relates to a kind of depth base
Mouth high-pressure grouting leak stopping processing method is buried in hole diaphram wall leakage drilling.
Background technology
The more and more common use of deep basal pit diaphram wall support form, construction technology are constructed by slot section framing,
Joint mostly uses I-shaped steel joint and is connected, and adjacent two groove segments joint area is often the weak spot of percolating water, in deep base
During cheating later stage excavation construction, the problem of being frequently encountered percolating water at underground continuous wall connector.To avoid diaphram wall
The common quality defect of joint percolating water, it will usually in the pre-buried high-pressure slip-casting pipe in joint, slip casting, but practical behaviour are carried out after grooving
In work leaking for joint area is influenced or is difficult to avoid that by stratum.Further, since the improper equal other reasons of concreting
Also it will appear the leakage problem at other positions.
During practice of construction, in the case of diaphram wall part leak paths are obvious, generally use water conservancy diversion
Tube Drain first blocks diversion pipe surrounding with plugging materials such as double-quick cements, is blocked up again after the intensity that plugging material reaches certain disconnected
Flow in diversion pipe is handled.It is the case where larger for leakage area and no apparent breakthrough and leak paths, above-mentioned
Method is difficult to be effectively treated.
Diaphram wall is mostly two-in-one design at present, must properly be located to the leakage in the diaphram wall face of appearance
Reason, to ensure the waterproof effect of underground structure.
Invention content
For overcome the deficiencies in the prior art, mouth high pressure is buried in a kind of deep basal pit diaphram wall leakage drilling of present invention offer
Grouting leak-stopping processing method forms the foaming induration with good sealing performance by this method, and to reach, sealing is stifled to be oozed
The effect of leakage, barrier performance are good.
The technical solution adopted by the present invention to solve the technical problems is：A kind of leakage drilling of deep basal pit diaphram wall is buried
Mouth high-pressure grouting leak stopping processing method, thes improvement is that：This method includes the following steps：
A, leakage or moist position are manually chiseled in the cleaning of leached surface, and detailed to check, analyze leakage scenarios, determination is oozed
The position of water spot and coverage；The region for needing leak stopping is cleaned out, concrete surface loosening junk is cut, it is ensured that surface is dry
Only；
B, tunneling boring drills, and tunneling boring drilling is carried out in leakage range, and according to the range of percolating water and position, setting
Drilling hole amount and range, and drilled by quincunx setting within the scope of the leakage with the center for leaking range, hereafter use electricity
Hammer drills in leakage range；
C, mouth is buried, slip casting is buried in drilling in stepb and buries mouth, i.e. Water slop injector, slip casting is made to bury the interior of mouth and drilling
Gapless between wall, it is water-tight；
D, high-pressure grouting includes the following steps：
D1, grouting material is chosen, using polyurethane as sealing grouting material, polyurethane is divided into water-soluble and oil-soluble two
Kind, by oil soluble polyurethane and soluble polyurethane by volume 1:2 ratio is mixed, and mixed solution is formed；
D2, choose bottler placer, the maximum output pressure of the bottler placer of selection is 10000psi, provide lasting pressure with
It is irrigated, pouring material is pressed into concrete structure inside microgap, slit and pore interstitital texture；
The mixed solution of the formation of oil soluble polyurethane and soluble polyurethane is poured into perfusion by d3, progress high-pressure slip-casting
In the material cup of machine, mixed solution is perfused into drilling by burying mouth in the interior inbuilt slip casting of drilling using bottler placer, had been perfused
Cheng Zhong is carried out around since the larger centre of leak, and the pouring squence on vertical metope is from top to bottom, molten when mixing
When liquid is emerged from crack, it should stop being perfused immediately；It moves into the slip casting closed on and buries and continue to be perfused in mouth；Pouring material is in concrete structure
Foaming induration is formed inside interior microgap, slit and pore interstitital texture；
E, it clears up, after grouting, the grouting material of cured spilling can be cleared up after confirmation is water-tight.
Further, further include following step after the step E：
F, it seals, the drilling of grouting is repaired using quick hardening cement, sealing treatment.
Further, in the step B, the bore diameter is 14mm, spacing of wells 10-20cm, drilling depth
For 17cm.
Further, in the step C, it is TT-A10 type Water slop injectors that mouth is buried in the slip casting, and the straight of mouth is buried in slip casting
Diameter is 13mm, and the length that mouth is buried in slip casting is 19cm.
Further, mouth is buried in the slip casting, and there is unidirectional flow, slip casting to bury when can prevent perfusion after mouth is tightened not
Spillage does not flow back.
The beneficial effects of the invention are as follows：The present invention uses the mixing of oil soluble polyurethane and soluble polyurethane, fully profit
The advantages of with two kinds of materials, not only plugging effect is more obvious, but also has the function of reinforcement and strengthening.Soluble polyurethane Bao Shui
Amount is big, and penetration radius is big, and consolidation body elasticity is good, is suitable for the leak stopping of dynamic water layer.Oil soluble polyurethane anti-permeability is good, material
