Problems solved by technology

However, the existing post-pouring belt structure makes it easy for rainwater and groundwater around the foundation pit to enter the foundation body from the deformation joints, and collect in the post-pouring belt and is difficult to discharge. In addition, the waterproof effect of the waterproof layer is not ideal, and it is easy to post-cast Cracks and water leakage occur after belt construction, which increases construction costs and delays the construction period

Abstract

The invention relates to the field of building construction, in particular to an anti-leakage construction method for a basement post-cast strip. The anti-leakage construction method comprises the following specific steps that step 1, a to-be-constructed area of the basement post-cast strip is cleaned, and a foundation bed is paved by concrete; step 2, after construction and maintenance of the foundation bed are completed, a layer of waterproof coiled material is paved on the foundation bed; step 3, the concrete is used for pouring a foundation body above the waterproof coiled material, and the foundation body is maintained; step 4, after maintenance of the foundation body is completed, the joint of the foundation body and the post-cast strip is roughened, and then the joint is coated witha bonding material layer; and step 5, the post-cast strip at the joint is poured by shrinkage-compensating concrete, and curing is carried out again. The anti-leakage construction method for the basement post-cast strip has the advantages of good waterproof and anti-leakage performance, simple structure and convenient construction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an anti-leakage construction method for basement post-cast belts. 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 large-area basement of high-rise buildings usually adopts the form of post-cast strips, which are used as temporary deformation joints left in the cast-in-place overall...
