Geotechnical engineering foundation pit anti-collapse supporting structure
The invention belongs to the technical field of foundation pit supporting, and particularly relates to a geotechnical engineering foundation pit anti-collapse supporting structure which comprises a box body, a fixing block is fixedly connected to the middle of the rear end face of the inner cavity wall of the box body, second sliding rods are fixedly connected to the two sides of the fixing block, and the second sliding rods are sleeved with and slidably connected with second sliding barrels. Two-way threaded rods are rotationally arranged at the upper end and the lower end of the box body correspondingly, threaded blocks are in threaded connection with the two sides of the two-way threaded rods correspondingly, first connecting rods are rotationally arranged at the two ends of the threaded blocks correspondingly, and one ends of the first connecting rods are rotationally connected with one side of the moving plate; a seamless expansion type supporting mechanism used for preventing stones at a foundation pit opening from falling off is further arranged at the upper end of the box body, the whole pit opening can be surrounded through the seamless expansion type supporting mechanism, when the stones move towards the pit opening, the stones can be blocked by the first arc-shaped plate and the second arc-shaped plate, and then the situation that the stones fall into a pit can be avoided; and the safety of operators is ensured.
本发明属于基坑支护技术领域，具体的说是一种岩土工程基坑防坍塌支护结构，包括箱体，所述箱体内腔壁后端面中部固定连接有固定块，所述固定块两侧均固定连接有滑杆二，所述滑杆二套设并滑动连接有滑筒二，所述滑筒二一端固定连接有移动板，所述箱体上下两端均转动设置有双向螺纹杆，所述双向螺纹杆两侧均螺纹连接有螺纹块，所述螺纹块两端均转动设置有连杆一，所述连杆一一端与移动板一侧转动相连，所述箱体上端还设置有用于防止基坑口石块掉落的无缝扩张式支护机构，本发明实现了利用无缝扩张式支护机构，可将整个坑口围住，当石块向坑口移动时，会被弧形板一和弧形板二阻挡住，进而可避免出现石块掉落至坑中的情况，保证了作业人员的安全。
