Self-advancing slide rail pendulous ground fissure deformation monitoring device

The invention belongs to the field of geologic hazard and prevention and control, and in particular relates to a self-advancing slide rail pendulous ground fissure deformation monitoring device. The device comprises self-advancing soil anchors, a bracket, an angle scale, a measuring line, a pulley, a pulley fixing rod, a slide rail type pendulum, a graduated slide rail box and a fixing clamp, wherein the bracket is fixed in stratums on the two sides of the ground fissure with the self-advancing soil anchors; a vertical relative movement angle of the ground fissure is measured through the angle scale; horizontal and vertical composite displacement can be measured through the slide rail type pendulum and the measuring line; and the measuring line can be replaced according to the requirements of different measuring ranges. By utilizing the self-advancing soil anchors, quick self-advancing installation and recovery of the monitoring device can be realized, and the slide rail pendulum is utilized to tension the measuring line and reduce the influence of environment on a tension device. The measuring line can meet the requirements of different measuring ranges and the length can be adjusted conveniently according to the requirements. The horizontal displacement and the vertical displacement of the ground fissure are measured by using a system consisting of the measuring line, the angle scale and the graduated slide rail box. The device has the advantages of simple structure and convenient assembling and disassembling.
