Abstract

The invention discloses a tunnel protection structure adjacent to a subway line, the tunnel protection structure comprises two symmetrically arranged wall-attaching devices, each of the two wall-attaching devices comprises two symmetrically arranged upright devices, each upright device comprises a stand column, a threaded groove is formed in the lower side wall of each stand column, a threaded column is in threaded connection with the interior of each threaded groove, and the lower side wall of each stand column is provided with a through hole; a floor is rotationally connected to the lower end face of the threaded column, a plurality of spikes are fixedly connected to the side wall, away from the threaded column, of the floor, two symmetrically-arranged cross beam devices are arranged between two stand columns in the wall attaching device, and side plates are fixedly connected to the side walls, close to each other, of the two stand columns. Cylinders are fixedly connected to the side walls of the upper ends of the two side plates correspondingly, and a transverse column is rotationally connected to the two cylinders jointly. Assembling and disassembling work can be completed conveniently and rapidly, a user can complete protection work conveniently and rapidly, and use of the user is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a tunnel protection structure adjacent to a subway line. Background technique [0002] Tunnels are engineering structures buried in the ground, and it is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, military tunnels, etc. Corresponding protective structures need to be set up during tunnel construction. [0003] Most of the existing tunnel protection structures are one-time construction, which cannot be easily disassembled and assembled. Therefore, it is very inconvenient to use when performing ordinary tunnel-related work, and it is extremely inconvenient for users to perform quick work. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to propose a tunnel protection structure adjacent to a subway line in order to solve the shortcomings existing in the ...
