Tunnel deep foundation pit side wall protection device
The invention discloses a tunnel deep foundation pit side wall protection device which comprises a side protection arm, the side protection arm is used for supporting the side wall of a tunnel, the side protection arm is movably connected with a bottom supporting arm, a plurality of reinforcing nails are arranged on the side, facing the bottom wall of the tunnel, of the bottom supporting arm, and the bottoms of the reinforcing nails penetrate into the bottom wall of the tunnel. A supporting mechanism is connected between the side protection arm and the bottom supporting arm, the supporting mechanism comprises inclined seats, the inclined seats are fixed to the side, away from the side wall of the tunnel, of the side protection arm and the top of the bottom supporting arm respectively, and inserting holes are formed in the inclined seats; the side protection arms and the bottom supporting arms are installed on the side wall of the built tunnel deep foundation pit to be matched, so that the tunnel deep foundation pits with different diameter specifications are used, and the side wall of the tunnel foundation pit can still be rapidly installed and supported in the tunnel deep foundation pits with the small movable diameter.
本发明公开了一种隧道深基坑侧壁防护装置，包括侧护臂，所述侧护臂用于支护隧道侧壁，所述侧护臂与底支撑臂之间活动连接，所述底支撑臂朝向隧道底壁的一侧设有多个加强钉，所述加强钉的底部深入隧道底壁，所述侧护臂与底支撑臂之间连接有支撑机构，所述支撑机构包括斜座，所述斜座分别固定在侧护臂背离隧道侧壁的一侧以及底支撑臂顶部上，所述斜座上均开设有插孔；本发明通过在修建的隧道深基坑侧壁安装侧护臂和底支撑臂配合，从而使用不同直径规格的隧道深基坑，进而在较小活动直径下的隧道深基坑中仍能够快速的安装并支撑隧基坑侧壁。
