Cast-in-situ tongue-and-groove type outer wall post-cast strip protection structure and construction method

Abstract

The invention provides a cast-in-situ tongue-and-groove type outer wall post-cast strip protection structure and a construction method, belongs to the technical field of underground construction, andsolves the technical problem that an existing post-cast strip protection structure has a poor self-waterproof effect. The cast-in-situ tongue-and-groove type outer wall post-cast strip protection structure comprises a left outer wall, a right outer wall, a left protection wall, a right protection wall and water sealing steel plates. The end parts of the left outer wall and the right outer wall areseparated; a post-cast strip is formed; the left protection wall is fixedly connected with the end part of the left outer wall; the right protection wall is fixedly connected with the end part of theright outer wall; the left protection wall and the right protection wall extend to the same side of the post-cast strip; the end parts of the left protection wall and the right protection wall are connected; the two water sealing steel plates are located in the post-cast strip; and one sides of the two water sealing steel plates stretch into the left wall body and the right wall body and are fixedly connected with the left wall body and the right wall body. The protection structure adopts concrete structure protection instead of conventional brick masonry protection so as to be good in waterproof effect and high in construction quality.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, and relates to a cast-in-situ groove-and-groove outer wall post-cast belt protection structure and a construction method. Background technique [0002] In the construction of cast-in-place concrete structures, in order to prevent harmful cracks that may occur due to uneven shrinkage or uneven settlement of the concrete itself, according to the design and construction specifications, temporary construction joints are usually left at the corresponding positions of the foundation floor, walls, and beams, and the overall The structure is temporarily divided into several construction areas. After the structural deformation is stable, temporary construction joints will be constructed to form post-casting belts. [0003] The post-cast belt can only be poured after the structure is capped or the settlement is stable. The waiting time is long, resulting in the impossibility of subsequent w...

Problems solved by technology

[0003] The post-cast belt can only be poured after the structure is capped or the settlement is stable. The waiting time is long, resulting in the impossibility of subsequent waterproofing, backfilling and other processes. Poor self-waterproofing effect, easy to seep water after backfilling
