[0002] In the technical field of rapid detection of tunnel section deformation, the heights of existing detection devices are mostly fixed and cannot be adjusted, but due to the different uses of tunnels, the heights set during construction are also different, and detection devices with fixed heights Adapt to different tunnels, so that the scope of application of the detection device is very small, which reduces the practicability of the detection device. The existing detection devices generally use sensors for detection. After the detection is completed, there is no identification device. When the detection device moves , the maintenance personnel cannot find the detected section accurately and quickly, which increases the workload of the maintenance personnel and makes the work efficiency low

[0003] The patent with the publication number CN110186420A discloses an automatic monitoring system for the convergence deformation of the tunnel section, including a deformation measurement device. When measuring the deformation of the tunnel section, the deformation measurement device is set on the surface of the tunnel lining or inside the tunnel lining, including a plurality of head and tail Connected sensor sub-sections, each sensor sub-section can measure the angle data between three mutually perpendicular directions and the direction of gravitational acceleration; the deformation data generation module, which is connected with the sensor sub-section, is used to determine the tunnel section according to the angle data The deformation data; although the patent can monitor whether the tunnel is deformed, it cannot realize mobile detection. The patent is fixed in one tunnel and cannot be used in multiple tunnels, and the use efficiency is low. At the same time, the patent cannot monitor the deformation of the tunnel. mark the location of the deformation, it is not convenient for the maintenance personnel to quickly find the deformation location
