Abstract
The invention discloses an anti-seepage continuous wall construction method. The method includes the following construction steps: A) selecting the diameter of a joint pipe according to the thickness of a continuous wall, and fixedly mounting a sawtooth projection on the outer wall of the joint pipe; B) integrally putting the joint pipe into a concrete construction trench section, and pouring concrete after reinforcement installation; C) after concrete setting, pulling out the joint pipe. The method has the advantages that concrete pouring is facilitated, and construction efficiency is improved; flange embedding and folding are not required, and construction cost is reduced; through changes of the continuous wall crack structure, waterstop effect is realized, and seepage resistance is improved.
Description
Technical field
The present invention relates to a kind of construction techniques, in particular, relate to a kind of construction method of diaphragm wall antiseep.
Background technology
The construction of connection wall be all generally adopt water proofing property higher from close formula concrete, diaphragm wall generally seepage itself is little, seepage generally all comes from joint seam place.Because diaphragm wall adopts section construction, therefore in the time that every section concrete is built, be all to adopt the vertical junction block that diameter conforms to substantially with diaphragm wall thickness that inserts in diaphragm wall segmentation place, as with the connecting sewing of next section of construction of diaphragm wall.After the last period, continuous wall concrete was built, in the time that concrete solidifies, vertically extract joint steel pipe, joint seam after having built presents the semicircle crescent shape that conforms to steel pipe, because the contact surface of semicircle crescent shape is greater than straight line, in the time that next section of diaphragm wall built, what two ends connection wall joint stitched just presents semicircle crater convex form.All generally to adopt this kind of method to improve joint seam contact surface, improve leakage resistance at present.
But semi-circular joint seam is plane contact, therefore still there is continuous wall connector seam seepage.Chinese invention patent application number is: CN201110140576.4, denomination of invention is: articulated joint of diaphragm wall, this patent is in diaphragm wall articulated joint place, be provided with wing plate and flanging part, increase stagnant water effect, but construction of diaphragm wall area is very large, increase wing plate and flanging, can increase Master Cost and affect efficiency of construction.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide one to prevent that diaphragm wall seam from leaking, improve efficiency of construction, reduce the construction method of the diaphragm wall antiseep of construction cost.
The construction method of diaphragm wall antiseep of the present invention, comprises following construction sequence:
A, in box cut inner side, diaphragm wall is set and leads wall, in the middle of diaphragm wall is led wall, build diaphragm wall and build A section 3, select the diameter of junction block according to the thickness of diaphragm wall, lateral wall at junction block fixedly mounts sawtooth projection and is welded and fixed three angle steel, form the three vertical tongue and grooves in road at continuous wall connector seam place by three angle steel, increase the keying strength between body of wall, also formed three seals groove simultaneously;
B, junction block entirety is put into concrete construction groove section, concreting is installed after reinforcing bar;
After C, concrete setting, junction block is extracted;
D, build diaphragm wall and build B section, build A section and diaphragm wall at diaphragm wall and build and between B section, form zigzag joint seam seal groove.
On described junction block outer wall, be provided with rectangular preiection.
Described angle steel width is 50-80mm.
The invention has the beneficial effects as follows: (1) concreting is convenient, improve efficiency of construction; (2), without pre-buried wing plate and flanging, lower construction cost; (3) by changing diaphragm wall crack structure, realize stagnant water effect, improve leakage resistance.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: box cut 1, diaphragm wall are led wall 2, diaphragm wall and built A section 3, junction block 4, diaphragm wall and build B section 5, joint seam 6, joint seam seal groove 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
In the drawings, the construction method of diaphragm wall antiseep of the present invention, comprises following construction sequence:
A, in box cut 1 inner side, diaphragm wall is set and leads wall 2, in the middle of diaphragm wall is led wall 2, build diaphragm wall and build A section 3, select the diameter of junction block 4 according to the thickness of diaphragm wall, fixedly mounting sawtooth projection and be welded and fixed three width at the lateral wall of junction block 4 is 60mm angle steel, stitch 6 places by three angle steel at continuous wall connector and form the three vertical tongue and grooves in road, increase the keying strength between body of wall, also formed three seals groove simultaneously, the seepage that has prevented continuous wall connector seam of maximum possible;
B, junction block 4 entirety are put into concrete construction groove section, concreting is installed after reinforcing bar;
After C, concrete setting, junction block 4 is extracted;
D, build diaphragm wall and build B section 5, build A section 3 and diaphragm wall at diaphragm wall and build between B section 5 and form zigzag joint seam seal groove 7, utilize the interlock of watering between walling can realize waterproof object, do not need to increase any supporting facility.
On described junction block 4 outer walls, be provided with rectangular preiection.
The present invention, by 4 structural changes of docking head tube, increases the contact surface of diaphragm wall, has also increased the snap-in force of two ends bodies of wall, and sealing notch has improved the anti-permeability of continuous wall connector seam, simple, with low cost, safe and reliable, successful greatly.
