Foundation pit supporting structure for foundation pit with tunnel on side wall

CHENG TAO / KOU WEIWEI / WANG HUICONG

The invention discloses a foundation pit supporting structure for a foundation pit with a tunnel on the side wall and belongs to the technical field of foundation pit construction. The structure comprises two moving seats; moving grooves are formed in the ends, close to each other, of the two moving seats; a same moving plate is slidably installed in the two moving grooves; first slide grooves areformed in the top of the two moving seats; first sliders are slidably installed in the two first slide grooves; inclined plates which are symmetrically arranged in an inclined mode are fixedly installed on the two first sliders; inclined seats are rotatably installed at the ends, away from each other, of the two inclined plates; supporting plates are fixedly installed at the ends, away from eachother, of the two inclined seats; supporting grooves are formed at the bottom ends of the two supporting plates; and supporting rods are slidably installed in the two supporting grooves. Through height adjustment of the supporting plates and extension of the two moving seats, the foundation pit supporting structure is applicable to foundation pits of different sizes, the limitation is reduced, theoperation is simple and application needs are satisfied.

本发明公开了一种基坑侧壁有隧道的基坑支护结构，属于基坑施工技术领域，其包括两个移动座，两个移动座相互靠近的一端均开设有移动槽，两个移动槽内滑动安装有同一个移动板，两个移动座的顶部均开设有第一滑槽，两个第一滑槽内均滑动安装有第一滑块，两个第一滑块上固定安装有倾斜对称设置的倾斜板，两个倾斜板相互远离的一端均转动安装有倾斜座，两个倾斜座相互远离的一端均固定安装有支撑板，两个支撑板的底端均开设有支撑槽，两个支撑槽内均滑动安装有支撑杆。本发明通过对支撑板进行高度调节和对两个移动座进行伸长，适应于不同大小的基坑，减小了局限性，操作简单，满足了使用的需要。
