The invention discloses a foundation pit supporting structure for excavation of a foundation pit. The foundation pit supporting structure comprises a base, a lead screw is rotatably connected to the upper end of the base, the side wall of the lead screw is in threaded connection with a lead screw nut, a plurality of fixed rods are fixedly connected to the upper end of the lead screw nut, a fixed column is jointly and fixedly connected to the upper ends of the multiple fixed rods, a vertical rod is rotatably connected to the upper end of the fixed column, and a first driving mechanism for driving the lead screw to rotate is installed on the base. According to the foundation pit supporting structure for the excavation of the foundation pit, a second gear drives a first gear to rotate by rotating a rotary shaft, then the fixed column is driven to slide, the height of a supporting plate is adjusted, and the operation is simple; a supporting angle of the supporting plate can be adjusted ona large scale by adjusting the position of a telescopic rod and a sliding block, and different conditions are conveniently and effectively supported; and a worm gear drives a double-threaded rod to rotate by rotating a worm, then a movable plate is driven to slide on the inner wall of a sliding chute, the supporting area of the supporting plate is adjusted, and thus better supporting is achieved.
本发明公开了一种基坑开挖用的基坑支护结构，包括底座，所述底座上端转动连接有丝杠，所述丝杠侧壁螺纹连接有丝杠螺母，所述丝杠螺母上端固定连接有多个固定杆，多个所述固定杆上端共同固定连接有固定柱，所述固定柱上端转动连接有竖杆，所述底座上安装有驱动丝杠转动的第一驱动机构。本发明通过转动转轴使得第二齿轮带动第一齿轮转动，进而带动固定柱滑动，对支撑板的高度进行调节，操作简单，通过调节伸缩杆和滑块的位置可以对支撑板的支撑角度进行大范围的调整，便于对不同情况进行有效的支撑，通过转动蜗杆使得蜗轮带动双头螺纹杆转动，进而带动活动板在滑槽内壁滑动，对支撑板的支撑面积进行调节，以便更好的进行支撑。
