Mounting device and mounting method for detector

Abstract

The invention discloses a mounting device and mounting method for a detector and belongs to the technical field of monitoring and prevention of geological disasters. The mounting device comprises a push plate, wherein a through hole is formed in the middle of the push plate; the top of the push plate is connected with a connector; an electric heating tube, a connecting rod and a spring are arranged at the bottom of the push plate; the lower end of the connecting rod is connected with a lower connection terminal; the lower end of the spring is connected with an upper connection terminal; the lower connection terminal and the upper connection terminal are in contact; the electric heating tube, the lower connection terminal and the upper connection terminal are sequentially connected in series through a power line; the push plate is connected with an ice block; and the electric heating tube, the connecting rod, the lower connection terminal, the spring, the upper connection terminal and the detector all are frozen into the ice block. The invention further discloses a mounting method for the detector. According to the mounting device and the mounting method, the detector can be smoothly arranged at the bottom of a drill hole in time before a hole collapses, so that coupling of the bottom of the detector and rock mass is ensured, the signal-to-noise ratio of collected data is improved and the device is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of geological disaster monitoring and prevention, and in particular relates to a detector installation device and an installation method thereof. Background technique [0002] The monitoring of rocky slopes has always been a weak link in the process of landslide monitoring and early warning. Existing conventional monitoring methods such as surface displacement, deep displacement, pore water pressure and rainfall monitoring methods are ineffective in response to rocky slope deformation monitoring and early warning and forecasting. There are deficiencies in the process. Rock deformation, landslides, earthquakes and other activities will cause rock fractures due to changes in ground stress before they occur, which is the condition for generating micro-seismic signals. Compared with conventional monitoring, microseismic monitoring directly monitors the damage of rock mass and monitors the essence of rock mass d...

Problems solved by technology

In the prior art, the geophone is generally hoisted to the bottom of the borehole by ropes, but since there will be loose soil, sand and gravel on the inner wall of the borehole, the geophone will touch the soil or sand during the descent of the geophone, causing the The position of the geophone is shifted, resulting in inaccurate installation position of the geophone and large errors in the detection results

In addition, if there is a lot of loose soil, sand, etc. on the inner wall of the borehole, these soils, sand, etc. are likely to block the geophone, resulting in the failure of the geophone to be installed to the bottom of the borehole.
