Abstract

Provided is an improved post-pouring strip advanced water-stopping construction method. A structure is thickened on a post-pouring strip portion in advance to form a whole, a post-pouring strip is stripped out, a water-swelling water-stopping strip is arranged in the middle of the thickened portion to meet the requirements of different settlement and telescopic deformation, and the water-stopping effect can be achieved before pouring of the post-pouring strip of a basement. The construction method includes the steps of digging of a post-pouring strip basic earthwork, bottom plate and post-pouring strip cushion layer construction, leveling blanket construction, waterproof layer construction, protective layer construction, installation of the post-pouring strip and an externally attached water-stopping strip, reinforced steel rib installation, formwork installation, installation of a post-pouring strip side face quick and simple net, basement bottom plate concrete pouring and post-pouring strip concrete construction. The basement does not leak water after construction by means of three local waterproof measures of the externally attached water-stopping strip, the water-swelling water-stopping strip and the post-pouring strip, water pumping is barely needed in the basement, construction is convenient, and operation is easy.

Description

technical field [0001] The invention relates to the layout or structure technology of the international patent classification E02D29 / 16 basic structure joints, especially the improved post-pouring belt advanced water-stop construction method. Background technique [0002] Advanced waterproofing means that before the post-casting belt is poured and the self-waterproofing function of the structure cannot be realized temporarily, the partial advanced waterproofing construction of the post-casting belt is carried out in advance to realize the dual functions of waterproofing and deformation joints. At the same time, after the construction of the basement is completed, the earthwork can be backfilled to reduce the safety hazard of the deep foundation pit, and the overall waterproof effect is ideal. The method of post-casting water-stopping generally refers to the waterproof scheme between the component and the water surface or before, and there are many methods of post-casting-top...
