Problems solved by technology

[0006] 1. The defects of the butter coupling probe mainly include: when the signal is transmitted in the butter, the attenuation is large, and the detection effect is poor; the butter and the soil layer are easy to penetrate, and the use cost is high; when the detection is recovered, the butter needs to be cleaned, which is difficult to clean
[0007] 2. The main defects of the casing coupling probe are: complex probe structure, difficult installation; difficult probe recovery, high cost; complete rigid coupling structure, can not adapt to the physical changes of rock and soil in the hole, long-term use, the probe and the hole wall The degree of fit is difficult to guarantee, which affects the signal transmission effect

Abstract

The invention discloses a mechanical adherent flexible coupling probe for geological detection. The probe comprises a sleeve and an oscillating wave sensor mounted in the sleeve. The problem is characterized in that the front end of the sleeve is provided with an axially flexible mechanical limiting head, and a prime mechanism is mounted in a cavity in the middle of the sleeve, and connected with a radial expansion mechanism. After being driven by a prime force, the prime mechanism drives the radial expansion mechanism to expand outwardly from the sidewall of the sleeve. The mechanical adherent flexible coupling probe for geological detection has the advantages that installation is convenient, recovery is easy, the manner by using button as couplant is replaced, long-term interference fit between the probe and a hole wall is ensured, and the signal transmission effect is ensured.

Description

[0001] The invention relates to a wall-adhering coupling detection device for geological exploration, in particular to a wall-adhering flexible coupling probe for mechanical geological exploration. Background technique [0002] Several existing geological advance prediction methods are: radar method, seismic method, drilling method, electromagnetic method, etc. The present invention is a sensor based on the seismic method. At present, two methods are mainly used at home and abroad: casing coupling probe and butter coupling probe. [0003] The coupling method of casing sensor is: put the sensor into the borehole to receive the seismic signal after casing the sensor, (Liu Baozhong. Application of TSP203 Geological Advance Prediction System in Tunnel Construction. Shanxi Architecture. June 2004, Vol. 30, No. 11), using butter as couplant (Liu Yunzhen, Mei Ruwu. New technology of TGP tunnel geological advance forecasting. Beijing Institute of Hydroelectric Geophysical Exploration)...
