LI DEMIN

The invention discloses a foundation pit supporting structure with a tunnel on the side wall of a foundation pit. The foundation pit supporting structure with the tunnel on the side wall of the foundation pit comprises a tunnel wall body and a base arranged on one side of the tunnel wall body, and a supporting column and a supporting rod installed in the supporting column in a sliding mode, wherein a supporting wall plate used for supporting the tunnel wall body is rotatably arranged on the base, the side, close to the tunnel wall body, of the supporting wall plate is provided with an anti-skid pad enabling connection to be tighter, and two supporting blocks used for supporting the base are symmetrically installed below the base; the supporting column is provided with a sliding cavity used for the supporting rod to slide up and down. According to the foundation pit supporting structure, the angle of the supporting wall plate can be adjusted according to the actual inclination degree of the tunnel wall body, the use practicability is improved, the supporting wall plate and the tunnel wall body are tightly attached, the overall supporting quality of the supporting wall plate is high, and potential safety hazards are greatly reduced.

本发明公开了一种基坑侧壁有隧道的基坑支护结构，所述基坑侧壁有隧道的基坑支护结构包括：隧道墙体以及设置在所述隧道墙体一侧的底座，所述底座上转动设置有用于支撑所述隧道墙体的支护墙板，所述支护墙板靠近所述隧道墙体的一侧安装有使连接更加紧密的防滑垫，所述底座下方对称安装有两个用于支撑所述底座的支撑块；支撑柱以及滑动安装在所述支撑柱内的支撑杆，所述支撑柱上设有用于所述支撑杆上下滑动的滑动腔。本发明的支护墙板就可以根据隧道墙体的实际倾斜程度，来调节角度，提高了使用的实用性，并且使得支护墙板和隧道墙体紧密贴合，支护墙板对整体的支护质量高，大大降低了安全隐患。
