[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of a tunnel body and a tunnel portal. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications, and drainage facilities. Long tunnels also have special ventilation and lighting equipment.

[0003] According to the patent document: CN212614890U, a detection bracket for detecting the flatness of tunnel walls is disclosed, including a connecting seat, a fixing block, a mounting plate and a detector. The right side of the connecting seat is inlaid with a fixing block, and the right side of the fixing block is provided with a mounting plate, and the detector is fixed by bolts above the mounting plate. The interior of the mounting plate is inlaid with an identification shell, and the left side of the mounting plate is inlaid with a transmission plate, and the left end of the transmission plate is located inside the fixed block. The interior of the transmission plate is penetrated by a movable shaft, and a worm is provided on the left side of the movable shaft, and the worm bearing is installed inside the fixed block. The detection bracket for detecting the flatness of tunnel walls is provided with an identification shell and a counterweight. After the bracket is installed, the counterweight can pull the pull rope downward under the action of gravity. The flatness of the mounting plate can be detected by observing the overlapping position of the pull rope and the identification line on the surface of the identification shell, thereby indirectly reflecting the flatness of the wall at that location and increasing the functionality of the device.
