Embodiment Construction

[0012] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Depend on Figure 1 to Figure 6 Given, the present invention includes a vertical outer tube, the outer tube is connected by a plurality of pipe joints 1 arranged up and down, the ends of each pipe joint 1 can be rotatably connected, and the bottom end of the pipe joint 1 is closed , the outer wall of each tube section 1 is fixed with a plurality of fins 2 evenly distributed around the circumference. If the rock and soil layer outside the pipe joint 1 moves in any direction, it will push the pipe joint 1 to rotate clockwise; the upper end of the outer pipe is provided with a horizontal cover plate 3 fixed on the ground, and the lower surface of the cover plate 3 is fixed with a The outer tube is coaxial with the inner tube 4, and an inner gear 5 is fixed on the inner wall of each pipe joint 1, and each inner gear ...

Abstract

The invention relates to a rock-soil interlayer shear motion detection device which effectively solves a problem that a stratum motion detection device is incomplete in function. The rock-soil interlayer shear motion detection device is characterized by comprising an outer pipe, wherein the outer pipe is formed by connecting a plurality of pipe sections, all the pipe sections are rotationally connected, a plurality of fins which are circumferentially and uniformly distributed are fixed on an outer wall of each pipe joint, the fins are shark fin-shaped, edge parts of the fins face one clockwiseside, the anticlockwise side of each fin is a plane vertical to the tube wall, when a rock-soil layer on the outer side of the pipe joint moves in any direction, the pipe joint can be pushed to rotate clockwise, a plurality of signal transmitting units are arranged at the upper end of the outer pipe, the signal transmitting units and the pipe joint are connected with pull ropes in a one-to-one correspondence mode, the pipe joint rotates to pull the corresponding signal transmitting units through the pull ropes, and therefore the signal transmitting units transmit signals. According to the rock-soil interlayer shear motion detection device, various forms of geological motions can be effectively monitored, so 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 shear motion 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 unidire...
