[0002] Deep foundation pits refer to deeper foundation pits dug in urban construction, usually used to build high-rise buildings or underground facilities. Near deep foundation pits, especially near subway tunnels, the stability of subway tunnels may be affected, so intelligent real-time monitoring is required to ensure the safe operation of the subway.

[0003] For example, the patent with announcement number CN211601924U discloses a deformation monitoring device for a subway tunnel, including an adjustment box and a computer. The adjustment box is provided with an angle adjustment groove, and a plurality of No. 1 screw rods are embedded on the side walls of the angle adjustment groove. The outer ends of the No. 1 screw rods are fixedly connected with fastening heads, and the outer sides of the inner ends of the No. 1 screw rods are rotatably sleeved with clamping plates. A linkage cavity is provided on the other side of the angle adjustment groove and is located in the adjustment box. A rotating shaft is rotatably embedded between two opposite side walls of the linkage cavity. One end of the rotating shaft extends into the angle adjustment groove and is fixedly connected with an angle adjustment plate. A rangefinder is clamped and fixed between adjacent angle adjustment plates and the clamping plates. The utility model provides a deformation monitoring device for a subway tunnel. The detection point of the rangefinder is directly opposite to the top wall of the tunnel.
