Problems solved by technology

[0002] The underground diaphragm wall often has water leakage as the enclosure structure of the foundation pit. There is a joint box (GXJ for short) installed with a rubber waterstop on the underground diaphragm wall, which has a good sealing effect on the water leakage at the joint of the underground diaphragm wall , but in the process of demoulding, it is difficult to demould the joint box and the cast-in-situ concrete underground diaphragm wall, and it is easy to damage the rubber waterstop and the joint box.

Abstract

The invention relates to a construction method for installing a rubber waterstop on an automatic folding joint box for an underground continuous wall, including guide wall construction, trench excavation, steel cage binding and lowering, joint box assembly and installation, concrete pouring and shrinkage joint box and hoisting out and other steps; the back panel, rear side panel, front side panel and front panel of the joint box are hingedly connected to each other and water-stop strips are used to seal the water. The hose clamping device and the clamping hydraulic arm, the folding hydraulic arm and the clamping hydraulic arm are connected to the hydraulic pump through independent hydraulic pipes, and the joint box is connected as a whole by fastening the tie rods; after the concrete of the underground diaphragm wall reaches a certain strength, the synchronous Shrink and fold the hydraulic arm and extend and clamp the hydraulic arm, so that the overall shrinkage, folding and clamping device of the joint box releases the rubber waterstop and lifts out the joint box. The invention can improve the water-tight and anti-seepage performance at the joint of the concrete underground continuous wall, has convenient and quick construction, and has better economic and social benefits.

Description

technical field [0001] The invention relates to a construction method for an underground continuous wall of cast-in-situ concrete, in particular to a construction method for installing a rubber waterstop on an automatic folding joint box for the underground continuous wall. Background technique [0002] The underground diaphragm wall often has water leakage as the enclosure structure of the foundation pit. There is a joint box (GXJ for short) installed with a rubber waterstop on the underground diaphragm wall, which has a good sealing effect on the water leakage at the joint of the underground diaphragm wall , but in the process of demoulding, it is difficult to demould the joint box and the cast-in-situ concrete underground diaphragm wall, and it is easy to damage the rubber waterstop and the joint box. Contents of the invention [0003] The object of the present invention is to propose a rubber waterstop construction method for installing an automatic folding joint box f...
