Shield tunnel displacement monitoring equipment

The utility model discloses a shield tunnel displacement monitoring device. The monitoring equipment comprises a driving mechanism which is fixedly installed at a tunnel monitoring point; the reflector is mounted on the inner wall of the stable surrounding rock of the tunnel; the laser transmitter is arranged on the driving mechanism, and the driving mechanism can drive the laser transmitter to move along a first direction relative to the reflector and rotate around a second direction, so that the laser transmitter is aligned with the reflector; the measuring mechanism is used for measuring the moving distance and the rotating angle of the laser transmitter; wherein the first direction refers to the horizontal direction perpendicular to the axis of the tunnel, and the first direction is parallel to the second direction. The shield tunnel displacement monitoring equipment has the advantages of being convenient to operate and low in monitoring cost. 本实用新型公开了一种盾构隧道位移监测设备。该监测设备包括：驱动机构，固定安装于隧道监测点处；反光片，安装在隧道稳定围岩内壁上
