Water-proofing and earthwork backfilling structure and method of late poured band coordinating with basement sidewall

Abstract

The invention discloses a structure for waterproofing and earth backfilling of a basement side wall post-cast belt, comprising a basement side wall, the side wall includes a post-cast belt extending in a vertical direction; wherein the structure further includes: a pre-embedded steel plate , it is pre-buried in the side walls on both sides of the post-casting belt during the construction of the basement side wall, and is exposed on the surface of the side wall; the channel steel parts are respectively welded on the pre-embedded steel plates on both sides of the post-casting belt, The pair of channel steel parts respectively form a slot with openings opposite to each other on both sides of the post-casting belt; the reinforced concrete prefabricated plate is inserted into the slot from top to bottom; waterproof coating is applied to the The seams between the channel steel parts and the pre-embedded steel plates, and the joints between both sides of the reinforced concrete prefabricated slab and the outer surface of the side wall; waterproof felt, which is laid outside the reinforced concrete prefabricated slab, and Cover the reinforced concrete prefabricated slab and waterproof coating. The invention also includes a construction method of the structure.

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 ...

AI Technical Summary

Problems solved by technology

For construction sites with narrow construction sites or projects that require precipitation, if the subsequent construction of waterproof layer, backfill soil, hardened site, etc. cannot be carried out in time, it will seriously affect the layout of the construction plane and construction progress on site, and prolong the construction period.
