Abstract

The invention discloses a device for installing and recovering a micro-vibration sensor in an aquiferous weak rock-soil body deep hole. The device comprises a hot galvanizing pipe arranged in a pre-drilled hole, a base arranged at the bottom of the hot galvanizing pipe in a sealed mode, a plurality of detachably-connected operating rods, a sensor base connected with the sensor, an installation sleeve and a recovery sleeve, wherein both the installation sleeve and the recovery sleeve are detachably connected with the operating rods, the base is provided with a base outer stud, a sensor base convex body is arranged on the lateral of the sensor base, the installation sleeve and the recovery sleeve are respectively provided with a sleeve clamping groove, and the bottom of the sensor base is provided with sensor base lower internal threads matched with the base outer stud. Accordingly, the problems that the sensor is difficult to install, protect and recover in the aquiferous weak rock-soil body deep hole are solved.

Description

technical field

[0001] The invention relates to the field of microseismic monitoring, in particular to a deep hole installation and recovery device for a microseismic sensor in watery and weak rock and soil, which is suitable for the field of microseismic on-site monitoring and experimentation. Background technique

[0002] Microseismic (microseismic) refers to the microvibration produced by the accumulation of energy in the rock itself in a local area to a certain extent, which induces cracks and destruction inside the rock under external disturbances, and the accumulated energy is released in the form of elastic waves. Microseismic monitoring technology is a new geophysical prospecting technology developed in the 1890s. The principle of this technology is to use sensors to collect vibration signals generated by the internal energy accumulated in the form of stress waves when rock cracks initiate, expand, and slip. , record the process and law of microseismic waveform chang...
