Foundation pit partition wall area bottom plate post-cast strip construction method
The invention provides a foundation pit partition wall area bottom plate post-cast strip construction method. The problems that in existing foundation pit partition wall part structure bottom plate post-cast strip construction, the quality of poured concrete is difficult to guarantee, underground water leakage is extremely likely to be caused, and profile steel support changing force transmission is not reliable are solved. The invention provides an assembly type force transmission structure convenient to mount quickly and with water stop, seepage prevention, water storage and drainage functions. Effective force transmission is formed through the prefabricated concrete force transmission units, multiple anti-seepage interfaces are arranged to effectively prevent underground water seepage, a waterproof baffle is arranged to prevent open water of a foundation pit from spreading, static expansion holes are reserved to facilitate dismantling of the force transmission structure and recycling of the prefabricated units, and cleaning of the structural bottom plate post-cast strip and construction quality control are facilitated. And favorable conditions are provided for construction of foundation pit engineering, so that the purpose of safe production is achieved.
本发明提供了一种基坑分隔墙区域底板后浇带施工方法，针对现有基坑中隔墙部位结构底板后浇带施工存在的浇筑混凝土质量难以保证、极易造成地下水渗漏、型钢换撑传力不可靠等问题。本发明提出一种便于快速安装且自带止水防渗与蓄排水功能的装配式传力构造，利用预制混凝土传力单元形成有效传力、设置多道防渗漏界面有效防止地下水渗漏、并设置隔水挡板防止基坑明水蔓延、预留静力膨胀孔便于传力构造拆除与预制单元回收利用，有利于结构底板后浇带的清理与施工质量控制，为基坑工程的施工提供有利条件，从而达到安全生产的目的。
