Foundation pit support structure for deep foundation pit construction

WU PENG / WU QINGHAI / ZHAO YONGTAO

The invention relates to a foundation pit support structure for deep foundation pit construction, which comprises a base plate, a plurality of drill bits are mounted at the bottom of the base plate, a cylinder is fixed at the top end of the base plate, detection mechanisms are arranged on two sides of the cylinder, and each detection mechanism comprises a detection rod mounted on two sides of the cylinder and a runner pipe fixed in the cylinder. The two detection rods are communicated with the circulation pipe, a ball body is movably installed in the circulation pipe, and reinforcing rods are installed between the column body and the two detection rods. The device has the beneficial effects that it can be ensured that the device is in a parallel state with the ground during installation, and uneven stress of the structure can be avoided; according to the device, the problems that an existing device is prone to causing construction safety accidents and increasing the construction difficulty are solved, meanwhile, the situation that part of engineering possibly needs to be adjusted or remade is avoided, the construction cost is reduced, and the construction period is shortened.

本发明涉及深基坑施工的基坑围护结构，其中包括：基板，所述基板的底部安装有多个钻头，且基板的顶端固定有柱体，所述柱体的两侧设置有检测机构，所述检测机构包括安装在柱体两侧的检测杆以及固定在柱体内部的流通管，两个所述检测杆与所述流通管相连通，所述流通管内部活动安装有球体，所述柱体与两个检测杆之间均安装有加固杆，其有益效果是，可以确保本发明安装时与地面处于平行状态，能够避免结构受力不均匀，且增加结构的变形和倾斜风险的情况，增加了本发明的稳定性和安全性，解决了现有装置容易引发施工安全事故，增加施工难度的问题，同时，避免了可能会需要调整或重做部分工程的情况，降低施工成本和工期。
