Foundation pit construction method using existing underground diaphragm wall
The invention discloses a foundation pit construction method utilizing an existing underground diaphragm wall, which comprises the following steps of: 1, rechecking the existing underground diaphragm wall to ensure that the integrity and the perpendicularity of the existing underground diaphragm wall are good; 2, the existing underground diaphragm wall serves as an outer-layer enclosure structure, a newly-built underground diaphragm wall is constructed on the inner side of the existing underground diaphragm wall to serve as an inner-layer enclosure structure, and an underground diaphragm wall composite structure is formed; 3, the foundation pit is excavated, and the existing underground diaphragm wall in the foundation pit is synchronously removed; 4, steel bars of the foundation pit bottom plate are connected with steel bars of the existing underground diaphragm wall located below the cushion layer; 5, a cushion layer and a foundation pit bottom plate are poured, the portion, located below the cushion layer, of the existing underground diaphragm wall serves as a pile foundation, and the pile foundation and the foundation pit bottom plate are connected into a whole; and 6, constructing an underground structure. The invention relates to the technical field of foundation pit construction, and can solve the problems that in the prior art, an existing underground diaphragm wall affects the construction progress of a foundation pit and an underground building and increases the workload.
本发明公开了一种利用既有地下连续墙的基坑施工方法，包括步骤：1、复检既有地下连续墙，确保既有地下连续墙的完整性和垂直度良好；2、将既有地下连续墙作为外层围护结构，在既有地下连续墙内侧施工新建地下连续墙作为内层围护结构，形成地下连续墙复合结构；3、开挖基坑，同步清除基坑内的既有地下连续墙；4、基坑底板的钢筋与位于垫层下方既有地下连续墙的钢筋连接；5、浇筑垫层和基坑底板，位于垫层下方的既有地下连续墙作为桩基础使用，且桩基础与基坑底板连接形成一个整体；6、施工地下结构。本发明涉及基坑施工技术领域，能够解决现有技术中既有地下连续墙影响基坑和地下建筑物施工进度和增加工作量的问题。
