Abstract

The invention discloses a basement post-cast strip anti-leakage construction method. A basement post-cast strip anti-leakage structure is used in the method; the structure comprises a water absorptionexpansion layer, a water stop strip, a concrete cushion layer, a reinforced concrete layer and a water absorption layer arranged on a post-cast strip, and can achieve an excellent anti-permeation effect; meanwhile, through the concrete cushion layer, the subsequent concrete casting and molding are more facilitated, and the stability and the firmness of the whole structure are guaranteed; a waterproof steel plate is arranged on the concrete cushion layer on the side wall of a groove body of the post-cast strip; the concrete cushion layer at the bottom of the groove body is provided with a baseplate and isolation plates arranged on the base plate; the steel plate butts against the isolation plates at two ends of the base plate; the thickness of the steel plate can be designed according toactual demands to guarantee total occupation of the bottom area (the concrete cushion layer can be extruded) of the groove body after installation with the base plate; and the base plate and the waterabsorption layer therein can be installed in the groove bottom after ahead manufacturing, so that the efficient and ordered implementation of whole procedures is guaranteed.

Description

technical field [0001] The invention relates to the technical field of waterproofing of post-casting belts, in particular to a construction method for preventing leakage of post-casting belts in a basement. Background technique [0002] The post-cast belt is to prevent the occurrence of harmful cracks in the cast-in-place reinforced concrete structure due to factors such as temperature and shrinkage unevenness during construction. The temporary construction joints set at the corresponding positions of the foundation floor, wall or beam temporarily divide the structure into For several parts, after a certain period of internal contraction of the components, the construction joint concrete is poured and tamped to connect the structure into a whole. In order to ensure the integrity of the structure and the impermeability of the basement structure, the basement floor of the large basement of high-rise buildings is usually in the form of post-cast strips, which are used as tempor...
