Rock-soil interlayer dislocation detection device

Abstract

The invention relates to a rock-soil interlayer dislocation detection device which effectively solves the problem that an existing stratum movement detection device is incomplete in function. According to the technical scheme, the device comprises an outer pipe, wherein the outer pipe is formed by connecting a plurality of pipe sections; the pipe sections are rotatably connected; each pipe sectionis internally provided with a rotating shaft coaxial with the pipe section; the plurality of rotating shafts corresponding to the plurality of pipe sections are sleeved together in an inner-outer manner; the multiple layers of rotating shafts can rotate relatively; the pipe sections can rotate to drive the rotating shafts corresponding to the pipe sections to rotate; a plurality of fins which arecircumferentially and evenly distributed are fixed to the outer wall of each pipe section; the fins are shark fin-shaped, the blade portions of the fins face the clockwise side, and the anticlockwiseside of each fin is a plane perpendicular to the pipe wall; a rock-soil layer on the outer side of each pipe section can push the corresponding pipe section to rotate clockwise when moving in any direction; multiple groups of signal transmitters are arranged at the upper end of the outer pipe; and the signal transmitters can transmit signals after the pipe sections drive the rotating shafts to rotate by a preset angle. According to the invention, various forms of geological motions can be effectively monitored, so that geological disasters can be effectively prevented.

Description

technical field [0001] The invention relates to the field of geological monitoring, in particular to a detection device for movement between rock and soil layers. Background technique [0002] The ubiquity of the dislocation between rock and soil layers has brought rock mass stability problems and geological disasters to many projects in the world; the detection of dislocation between rock and soil layers is an effective measure to prevent geological disasters. The detection device for the overall movement of the layer is relatively common, but the detection device for the relative shear motion between the layers is less and the function is not perfect. The detection device for the interlayer dislocation is generally a multi-layer structure. This type of device cannot effectively detect the geological movement where the overall movement of rock and soil layers is large and the relative movement between layers is small, and this type of device is generally used in unidirectio...
