Foundation pit supporting device and foundation pit supporting method

SHI MEILING / PENG SHIHAI

The invention discloses a foundation pit supporting device and a foundation pit supporting method, relates to the technical field of foundation pit supporting, and solves the problems that a soil retaining plate of the foundation pit supporting device is easy to collapse and fall after being used for a long time, and a foundation pile is easy to collapse due to inward inclination caused by being pushed and pressed by soil. The foundation pit supporting device comprises foundation pile mechanisms, a soil retaining mechanism is movably installed between every two foundation pile mechanisms, anchor pile mechanisms are arranged on the outer sides of the foundation pile mechanisms, the foundation pile mechanisms and the soil retaining mechanisms are installed in a foundation pit, and the outer sides of the foundation pile mechanisms and the soil retaining mechanisms are filled with backfill soil. Through cooperation of the first rotating plate and the second rotating plate, the first rotating plate and the second rotating plate which are installed in parallel and vertically can be fixed correspondingly, the situation that the first rotating plate and the second rotating plate are loosened is prevented, and foundation pits of different sizes can be supported through cooperation of the foundation piles and the first soil retaining plates.

本发明公开了一种基坑支护装置以及基坑支护方法，涉及基坑支护技术领域，解决了基坑支护装置的挡土板使用时间长后容易坍塌掉落，且基桩容易被土推压而向内倾斜容易倒塌的问题。一种基坑支护装置以及基坑支护方法，包括基桩机构，每两个所述基桩机构之间均活动安装有挡土机构，所述基桩机构的外侧均设有锚桩机构，所述基桩机构和挡土机构均安装在基坑的内部，所述基桩机构和挡土机构的外侧填充有回填土。本发明通过第一转动板和第二转动板的配合，可对平行和垂直安装的第一转动板和第二转动板分别进行固定，防止第一转动板和第二转动板松动的情况，通过基桩和第一挡土板的配合，可对不同大小的基坑进行支护。
