A device for detecting movement between rock and soil layers

Abstract

The invention relates to a detection device for movement between rock and soil layers, which effectively solves the problem of the imperfect function of the current detection device for formation movement; The pipe joints are rotatably connected, and each pipe joint is provided with a coaxial rotating shaft, and multiple rotating shafts corresponding to multiple pipe joints are set inside and outside together, and the multi-layer rotating shafts can rotate relative to each other, and the pipe joints can rotate Drive the corresponding rotating shaft to rotate, and the outer wall of each pipe joint is fixed with a plurality of fins evenly distributed around the circumference. The fins are in the shape of shark fins and the blade faces clockwise. The wall is vertical to the plane, and the movement of the rock and soil layer outside the pipe joint in any direction will push the pipe joint to rotate clockwise; there are multiple sets of signal transmitters at the upper end of the outer tube, and the signal transmitter can transmit signals after the pipe joint drives the rotating shaft to rotate at a preset angle; The invention can effectively monitor various geological movements, so as to effectively prevent geological disasters.

Description

technical field [0001] The invention relates to the field of geological monitoring, in particular to a device for detecting displacement between rock and soil layers. Background technique [0002] The universality of interlayer dislocation of rock and soil has brought rock stability problems and geological disasters to many projects in the world; the detection of interlayer dislocation of rock and soil is an effective measure to prevent geological disasters. The detection devices for the overall movement of the layers are relatively common, but the detection devices for the relative shear motion between layers are few and their functions are not perfect. The detection devices for interlayer dislocation are generally multi-layer structures. This kind of device cannot effectively detect the geological movement that the overall movement of the rock and soil layer is large but the relative movement between the layers is small, and this type of device is generally used in a unidi...
