CHEN PEIPEI / WANG MANQI / ZHU RUISONG / HA ZHEN / MA LIJUN

The invention discloses a prefabricated ecological foundation pit supporting structure and method.The foundation pit supporting structure comprises a first supporting mechanism, a second supporting mechanism and a middle connecting mechanism, the first supporting mechanism comprises a first supporting frame, and a first supporting plate is arranged on the inner side of the first supporting frame; the first supporting mechanism comprises a first supporting frame, a first outer supporting pile is obliquely arranged at the top of the first supporting frame, the second supporting mechanism comprises a second supporting frame, a second supporting plate is arranged on the inner side of the second supporting frame, a second outer supporting pile is obliquely arranged at the top of the second supporting frame, and the two ends of the middle connecting mechanism are detachably connected with the first supporting frame and the second supporting frame respectively. Standardization of components of the foundation pit supporting structure is achieved in a prefabricated assembly mode, a large number of tedious construction steps are omitted, assembly is easy, construction is convenient and fast, the construction period can be greatly shortened, the construction efficiency is improved, all the standardized components can be used repeatedly, and the construction cost is reduced.

本发明公开了一种预制装配式生态型基坑支护结构及支护方法，该基坑支护结构包括第一支护机构、第二支护机构和中间连接机构，第一支护机构包括第一支护框架，第一支护框架的内侧设有第一支护板，第一支护框架的顶部倾斜设有第一外支护桩，第二支护机构包括第二支护框架，第二支护框架的内侧设有第二支护板，第二支护框架的顶部倾斜设有第二外支护桩，中间连接机构的两端分别与第一支护框架和第二支护框架可拆卸连接。本发明通过预制装配的方式实现了基坑支护结构部件的标准化，省去了大量繁琐施工步骤，其装配简单，施工方便快捷，可大大减少施工周期，提高施工效率，而且各个标准化的部件可周转多次使用，降低了施工成本。
