Description
技术领域technical field

背景技术Background technique
在建筑结构工程施工中，地下室外墙防水施工及基坑回填土一般需要在地下室竖向后浇带封堵完成后才能进行，然而按照图纸设计要求竖向后浇带封堵即后浇带混凝土浇筑一般需要在地下室外墙混凝土浇筑60 天后，等外墙的收缩变形基本完成后才能进行浇筑，然后才能进行地下室外墙外侧的防水施工和回填土工序，这样就大大降低了施工进度。目前大多数采用砖砌挡土墙的方法将地下室外墙竖向后浇带封堵，这种砖砌筑的施工方法施工复杂、封堵后还需要抹灰处理才能进行防水施工工程量大、封堵工期长，而且封堵效果差。In the construction of building structure engineering, the waterproof construction of the basement exterior wall and the backfilling of the foundation pit generally need to be carried out after the vertical post-cast belt sealing of the basement is completed. The pouring generally needs to be done 60 days after the concrete pouring of the basement exterior wall, and the shrinkage deformation of the exterior wall is basically completed before the pouring can be carried out, and then the waterproofing construction and backfilling process on the exterior of the basement exterior wall can be carried out, which greatly reduces the construction progress. At present, most of the method of brick retaining wall is used to block the vertical post-cast belt of the basement exterior wall. The construction method of this brick masonry construction is complicated, and plastering is required after sealing to carry out waterproof construction. The plugging period is long and the plugging effect is poor.
