Description
Technical field
The present invention relates to architectural engineering recovery technique field, specially a kind of diaphram wall restorative procedure.
Background technique
Diaphram wall can be divided into cast-in-place diaphram wall and coercion underground continuous wall two major classes, apply in engineering at present
The slot section form of cast-in-place diaphram wall mainly have wallboard type, T-type and П shape etc., and can be by by various forms slot section group
It closes, forms the structure types such as trellis, cylindrical shape.Diaphram wall is that foundation engineering uses a kind of trench machine, edge on the ground
The periphery axis of deep excavation project excavate out a long and narrow deep trouth under the conditions of mud off, after clear slot, hung in slot
Steel reinforcement cage is put, then builds up a unit groove section with tremie method underwater concreting with tremie method, so carries out paragraph by paragraph, builds up one in underground
The continuous armored concrete wall in road, as intercept water, antiseepage, load-bearing, water-retaining structure.
After decades of development, the technology of diaphram wall is quite mature, and diaphram wall is
Instead of many traditional construction methods, and it is used for many aspects of foundation engineering.Diaphram wall in the construction process, because each
Kind factor leads to the concrete defect of some diaphram walls, and defect directly affects construction quality and safety, needs to connect underground
Continuous wall is repaired, and it is incomplete to obtain renovation technique to diaphram wall at present, and traditional leak stopping etc. repairs operating method right
Its waterproof, antiseptic property are poor after diaphram wall is repaired, the inadequate persistence of plugging effect, to solve the above-mentioned problems, therefore,
Design a kind of diaphram wall restorative procedure.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of diaphram wall restorative procedure
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of diaphram wall restorative procedure, including it is following
Several steps:
S1, tentatively judge diaphram wall position to be repaired, staff judges that diaphram wall is repaired using detection device
Multiple reparation position is determining and repairs depth, and determines adjacent existing intact diaphram wall projected depth.
S2, reason is repaired according to the data parameters analysis diaphram wall detected, common diaphram wall needs are repaired
Multiple problem includes: (1) percolating water；(2) bulge and leakage muscle.
S3, preliminary planning diaphram wall repair process mode: (1) Seepage water includes water seepage treatment and gushes at sand
Reason；(2) bulge and leakage muscle processing.
S4, diaphram wall repairing construction process flow: (1) leak stopping reparation at diaphram wall percolating water is formulated: leakage
Position determination-drafting expanded view-leakage analysis-determines waterproofing-seepage place cleaning-closure, drilling-peace
Fill high-pressure slip-casting-mud jacking-diaphram wall defect repair-brushing polymer waterproof, erosion resistant coating；
(2) bulge and leakage muscle reparation: bulge and leakage muscle portion position determination-drafting expanded view-bulge and leakage muscle portion position reason
Analyze-determine mending option-rejected region cleaning-diaphram wall defect repair-brushing polymer waterproof, erosion resistant coating.
S5, be directed to diaphram wall percolating water repairing construction Specific construction operating procedure: (1) underground continuous wall seam seeps
When water is little, centered on leakage point, artificial seam crossing of digging is rinsed well groove with water at groove, is directlyed adopt double
Fast cement is rapidly jammed in groove, and secret room is then applied in recessed joint cell wall and squeezed with tool, is covered until double quick water
Mud fever solidification；
(2) if continuous wall seam leak is larger, grouting for water plugging need to be used:
The first step is in seam two sides or upper and lower each 15cm or so arrangement grout hole；
Second step buries grouting nozzle, after the insertion drilling of pressure ring grouting nozzle, with spanner rotating nut, i.e. compression movable sleeve
Pipe and pressure ring, make elastic rubber ring expand and compress to hole wall surrounding, couple grouting nozzle and hole wall securely, observation blocks situation
With each hole connection situation, it is normally carried out with guaranteeing to be in the milk；
Grouting equipment is installed and checked to third step, to ensure the safe handling in grouting construction；
4th step select a wherein hole slip casting, be typically chosen in lower and the biggish grouting nozzle of leak, after it is porous see slurry after,
Each hole is closed immediately, still persistently mud jacking, grouting pressure should be greater than leakage water pressure, promote slurries inversely along leak paths,
It infuses not when into slurry, stops mud jacking, close grouting nozzle immediately, in order to prevent the reflux of slurries, block grouting pipe, Ying Xianguan
The valve of grouting nozzle is closed, then stops mud jacking, after slip casting, grouting equipment should be cleaned immediately, is used again convenient for next time；
5th step rejects grouting nozzle after grout cures, carries out surface regulation, and observe grouting for water plugging effect, when necessary
Repeatable slip casting；
6th step surface construction flexible waterproof material or brushing polymer waterproof, erosion resistant coating at the hole after slip casting.
S6, diaphram wall bulge and leakage muscle repairing construction Specific construction operating procedure are directed to:
(1) bulge is handled: the method for taking stage excavation, layered shaping first, under earth excavation to bulge top surface
Suspend when 1.0m and excavate, it is quasi- take manually to hold pneumatic pick and cut abolish, exposure one must be excavated immediately following earth excavation progress by abolishing bulge
Section abolishes one section in time；
(2) leakage muscle processing: muscle face must be leaked to diaphram wall and carry out dabbing, cleaning, high-pressure blast and water cleaning, then to leakage
Muscle face is good that sand finish must leak muscle face for large area using medium coarse sand mixing using mixing, sprays coagulation using spraying machine
Soil carries out Seal treatment, manually has a shave levelling, reaches basal plane and check and accept to obtain standard.
As a preferred technical solution of the present invention, 16-24cm of pitch-row of the injected hole, hole depth >=30cm is tiltedly worn
Crack, 8-14mm of aperture.
As a preferred technical solution of the present invention, the selection of the slip casting hole site should make bottom and the leakage of injected hole
Water gap intersection, be selected in the maximum position of water leakage, it is good to reach transmissibility, under normal circumstances, horizontal fracture preferably along seam under to
Upper deflecting hole；Make straight hole in the suitable face gap of vertical fracture.
As a preferred technical solution of the present invention, the depth of the injected hole should not penetrate works, stay 10-
20cm length is safe distance.
As a preferred technical solution of the present invention, the pitch-row of the injected hole should regard leak pressure, gap size, leakage
Depending on water is how many and the dilation angle of slurries, generally 50-100cm.
As a preferred technical solution of the present invention, the embedded number of the grouting nozzle should be no less than two, that is, set one
Mouth is draining or gas nozzle, and another mouth is grouting nozzle, makes a hole as single hole leak can also push up water, buries a grouting nozzle.
As a preferred technical solution of the present invention, the chemical grouting agent is soluble polyurethane grouting agent.
As a preferred technical solution of the present invention, the polymer waterproof, the polymerization that erosion resistant coating is machine, inorganic compounding
Object material.
Compared with prior art, the beneficial effects of the present invention are: the present invention obtain diaphram wall restorative procedure mainly for
Percolating water, bulge and leakage muscle problem is obtained in diaphram wall to be repaired, it is detailed for different diaphram wall percolating waters,
