Recyclable micro-seismic sensor drilling rapid installation device and method

Abstract

The invention discloses a recyclable micro-seismic sensor drilling rapid installation device and method. The device comprises a water-soluble coupling agent flexible paste, a tamping block body, a sensor clamping sleeve, a reused pushing pipe, a hole protecting sleeve and a water filling rubber pipe. The inner wall of a drilled hole is protected through the hole protecting sleeve; the tamping block body is pushed through the reused pushing pipe to compact the water-soluble coupling agent flexible paste at the bottom of the drilled hole to form a water-soluble coupling agent base; the sensor clamping sleeve on which a micro-seismic sensor is placed is pushed into the water-soluble coupling agent base before solidification through the reused pushing pipe; the water filling rubber pipe communicates through the reused pushing pipe to inject water into the solidified water-soluble coupling agent base under pressure, and the sensor clamping sleeve provided with the micro-seismic sensor is pulled out of the dissolved water-soluble coupling agent base through the reused pushing pipe. The device is simple in structure, low in cost and easy to produce; and a water-soluble coupling agent material is creatively adopted, so that the complexity of a recyclable sensor mounting device (machine) is greatly reduced.

Description

technical field [0001] The present invention relates to a retrievable microseismic sensor drilling fast installation and recovery device and method, and relates to various geotechnical engineering such as mines, tunnels, slopes and other geotechnical engineering in the rapid installation and recovery technology of microseismic and acoustic emission sensors in drilling holes, and can also be used Expand to a wider range of sensor drilling and rapid installation and recovery technologies such as stress sensors, displacement sensors, and electromagnetic radiation sensors. Background technique [0002] Microseismic / acoustic emission monitoring technology refers to a passive geophysical monitoring technology that uses the vibration signals generated during the destruction of coal and rock mass to study the stability of coal and rock mass. Microseismic / acoustic emission monitoring technology was first used to study rockburst in hard rock mines. In recent years, this technology ha...
