Construction technology for anti-crack and waterproof structure of post-cast strip

Abstract

The invention provides a construction technology for an anti-crack and waterproof structure of a post-cast strip. The construction technology comprises the following steps that fine stone waterproof concrete strips are poured; steel bars at a slab bottom are bound; a lower-layer dense hole steel wire frame is arranged; water stop steel plates are arranged; an upper-layer dense hole steel wire frame is arranged; steel bars at a slab top are bound; a mold is hoisted; concrete on the two sides of the post-cast strip is poured; mold stripping and maintenance are carried out; the dense hole steel wire frames are disassembled; and concrete in the post-cast strip is poured (the concrete in the post-cast strip can be poured only when the design requirement deadline is reached). The construction technology aims to solve the problem that sedimentation of the concrete in the post-cast strip is caused due to the facts that in a traditional technology, a gap is reserved between a steel wire mesh and a base layer, and the concrete always flows into the post-cast strip from the gap in the vibration process of the concrete.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction process for a crack-resistant and waterproof structure with a post-cast belt. Background technique [0002] In domestic post-casting belt construction, micro-expansion concrete is often poured in the post-casting belt, and the micro-expansion concrete can be connected with the concrete on both sides of the post-casting belt to form a whole to play a good waterproof effect. [0003] However, many years of engineering practice have shown that the post-casting zone is still a frequent site of water leakage. The main reason is that the uneven settlement of the foundation and the anti-floating effect of the foundation floor affect the concrete on both sides of the post-casting zone and cause excessive settlement. Cracks resulting in leakage. [0004] At the same time, there is a gap between the steel wire mesh and the base layer in the traditional process. During ...
