Sliding mass deep integrated sensor laying device and monitoring method

Abstract

The invention provides a sliding mass deep integrated sensor laying device and a monitoring method; casing pipes extend in the vertical direction and are used for being lowered into a drill hole, and mounting holes are formed in the side walls of the casing pipes in a penetrating mode; a jacking body is mounted in each mounting hole, a jacking groove is formed in the side, facing the interior of each casing pipe, of each jacking body, a flexible body is attached to the inner side wall of each casing pipe, one end of each flexible body is connected with the corresponding jacking body, the other end of the flexible body is located in the corresponding casing pipe, and a sensor is mounted on each flexible body; and a pushing part is connected with a driving mechanism and used for being lowered to the position, opposite to a jacking groove, in the drill hole, and the driving mechanism drives the pushing part to move in the direction of the jacking groove so that the jacking bodies and the flexible bodies can penetrate through the mounting holes to be jacked into the drill hole. The technical scheme provided by the invention has the beneficial effects that the operation is simple, the automation degree is high, disturbance of a monitoring environment is reduced by a static jacking mode, the out-of-hole layout range is increased by a one-way bending chain type layout method, the method can be better close to an original underground environment, and more accurate landslide underground multi-field information can be measured.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring and prevention, in particular to a deep integrated sensor layout device and monitoring method of a sliding body. Background technique [0002] Landslide geological hazards are a more dangerous category of natural disasters, with high frequency, wide range of damage, and strong hazards, causing a large number of casualties and huge economic losses every year. Carrying out the development of landslide monitoring equipment, and then realizing the prediction and early warning of landslides, can minimize the loss caused by landslides, which is an important measure to deal with landslide geological disasters. [0003] For a long time, landslide monitoring has focused on the capture of surface geological parameters of landslides, including surface deformation, surface runoff, seepage, and ground fissures. In addition to deep deformation and seepage, the acquisition of deep geologi...
