Random-direction whole-hole section three-direction rigid coupling sensor installing and recycling device

Abstract

The invention discloses a random-direction whole-hole section three-direction rigid coupling sensor installing and recycling device which comprises a fixing, installing and recycling device and an installing and recycling rod.The fixing, installing and recycling device comprises a pushing table, expanding rods, hole wall supporting sheets, a threaded rod, a butt-joint threaded base hole, a butt-joint threaded base, a base, expanding rod and hole wall supporting sheet connecting pins, bottom fixing claws, base and expanding rod connecting pins and pushing table and expanding rod connecting pins.The installing and recycling rod comprises a hand-operated rocker, a titanium alloy steel pipe, a hexagonal mold block and a trumpet-shaped guiding opening.According to the device, the purposes of well coupling a sensor and the rock wall in a rock body and recycling the sensor are achieved, the sensor is separated from the butt-joint threaded base through the threaded rod by rotating the hand-operated rocker, operation is convenient, and the problem that the sensor is difficult to recycle in a deep hole is solved.

Description

technical field [0001] The invention relates to the field of transmission, in particular to a device for installing and recovering a three-way rigid coupling sensor with a full hole section in any direction. Background technique [0002] Microseismic monitoring technology is one of the important means of rock engineering disaster monitoring and prevention and control. Sensor installation and recovery is an important part of microseismic monitoring technology. How to install sensors can ensure good coupling with the medium and facilitate recovery. Monitoring cost control is crucial. At present, there are many sensor installation and recovery methods on the market, which can be roughly divided into two categories. One is the non-recoverable type. In this method, the sensor is directly sealed and filled in the borehole with concrete or other couplants. The monitoring effect of this method is generally relatively low. Good, but the sensor cannot be recovered, and it cannot be r...

Problems solved by technology

At present, there are many sensor installation and recovery methods on the market, which can be roughly divided into two categories. One is the non-recoverable type. In this method, the sensor is directly sealed and filled in the borehole with concrete or other couplants. The monitoring effect of this method is generally relatively low. Good, but the sensor cannot be recovered, and it cannot be repaired and replaced if it fails later, and the monitoring cost is high; the other is the recyclable type, which mainly uses anchoring agent to fix the sensor at the bottom of the borehole, or connects the sensor to the Rock mass medium coupling, these installation and recovery methods are mostly designed for a certain geological condition of a certain project, which can solve some engineering problems very well, but there are still many deficiencies: for example, the bottom installation method cannot be better To receive the signals transmitted from the other two directions, the drilling can only be inclined upward, compared with the slope engineering drilling downward, and one drilling needs to install multiple sensors, this method is difficult to meet the needs of monitoring; the wedge method is simple and convenient , but in this method the sensor is only coupled to the borehole wall and cannot receive the signal transmitted from the bottom of the borehole well

At present, the existing methods lack certain universality. A project often needs to design multiple installation methods, which is time-consuming and expensive and affects the in-depth analysis of microseismic information.
