Foundation pit supporting device with tunnel on side wall of foundation pit

GUO YANHUI / ROLO

The invention relates to the technical field of foundation pit supporting, in particular to a foundation pit supporting device with a tunnel on the side wall of a foundation pit, which comprises a movable base, a stable supporting adjusting device is arranged at the top of the movable base, and the stable supporting adjusting device comprises a protection box, a driving motor is fixedly connected in the protection box, and the driving motor is connected with the movable base. An output shaft of the driving motor is connected with a threaded rod in a clamped mode. A clamping seat is fixedly connected to the surface of the sliding arm seat, and a clamping device is arranged in the clamping seat; a mounting base is fixed to one end of the sliding rod, a top plate is rotationally arranged in the mounting base, and a supporting plate is fixed to the surface of the top plate. Through the structures such as the driving motor, after the supporting plate makes contact with the tunnel face, angle adjustment is conducted through moving force, the angle and position of the supporting plate are fixed through the clamping device, the stability in the supporting and protecting period is improved, the effect of automatically adjusting the supporting angle is achieved, and different tunnels can be conveniently supported.

本发明涉及基坑支护技术领域，具体为一种基坑侧壁有隧道的基坑支护装置，包括移动底座，所述移动底座的顶部设置有稳固支护调节装置，所述稳固支护调节装置包括有：防护箱，所述防护箱的内部固定连接有主动电机，所述主动电机的输出轴卡接有螺纹杆；滑动臂座，所述滑动臂座的表面固定连接有卡座，所述卡座的内部设置有卡接装置；滑杆，所述滑杆的一端固定有安装座，所述安装座的内部转动有顶板，所述顶板的表面固定有支护板。本发明通过主动电机等结构使得支护板与隧道面接触后利用移动的力进行角度调节，通过卡接装置固定支护板角度与位置，提高支撑防护期间稳定性，具备自动调节支护角度的效果，便于对不同隧道进行支护。
