Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a structure and a method for waterproofing and earthwork backfilling of basement side walls. Background technique

[0002] The post-pouring belt is a temporary part set at the corresponding positions of the foundation floor, wall and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. construction joints. The post-pouring belt temporarily divides the structure into several parts, and after a certain period of time, the construction joint concrete is poured and tamped after the internal contraction of the components to connect the structure into a whole.

[0003] In the basement construction with a post-pouring belt, the waterproof layer on the outside of the basement is affected due to the post-pouring belt being left for a long time, and the ...
