Description

Basement side wall leakage curtain grouting repairing structure Technical Field The utility model relates to the field of basement side wall waterproofing, in particular to a basement side wall leakage curtain grouting repairing structure. Background Basement side wall leakage is a common quality problem in constructional engineering and is mainly caused by structural defects, waterproof failure, groundwater pressure and other factors. Analysis of leakage causes (1) structural defects And (3) concrete cracks, namely casting unevenly, curing inadequately and causing cracks by shrinkage stress. And constructing cold joints, namely treating the joints inappropriately during layered pouring. Honeycomb and hole, the vibration is not compact, and the concrete has gaps. (2) Failure of waterproof layer The waterproof material is aged, and the flexible waterproof layer (such as SBS coiled material and polyurethane coating) is cracked or peeled off. And the lap joint is not tight, and the joint of the waterproof coiled material or the paint is not tightly sealed. And (5) damage, namely, backfilling soil or subsequent construction to damage the waterproof layer. (3) External water pressure influence High groundwater level, and hydrostatic pressure increase caused by rainy season or unsmooth drainage. The drainage system fails, and blind ditches and water collecting wells are blocked, so that water can not be effectively guided. (3) Other factors And (3) leaking the post-cast strip and the construction joint, namely improper installation or aging of the water stop strip (steel plate/rubber). Leakage of the wall pipe, i.e. the plugging of the sleeve is not tight (such as the periphery of a cable and a water pipe). The common repairing mode is mainly in a grouting plugging mode, the prior patent is entitled to CN221972497U, the repairing structure comprises a wall body, a plurality of through holes are horizontally arranged on the wall body in a penetrating mode along the vertical direction, feeding pieces are horizontally inserted into the through holes of the wall body, a water seepage surface is arranged on the outer side of the wall body and used for conveying slurry to form a waterproof slurry layer between the wall body and the water seepage surface, the feeding pieces comprise guide pieces, keels and plugging pieces, each guide piece comprises a guide cylinder, the guide cylinders are horizontally inserted into the through holes of the wall body, a hole frame is fixed at one end, close to the water seepage surface, of the guide cylinder, and a baffle plate is arranged at one end, close to the water seepage surface, of the guide cylinder.
