Borehole radar antenna automatic detection auxiliary device for advanced geological detection of tunnels

Abstract

The invention provides an automatic detection auxiliary device for borehole radar antennas for advanced geological detection of tunnels, including an automatic walking device in a hole and a borehole radar cable transmitter. The moving wheel driving device in the automatic walking device in the hole can control the rotation of the moving wheel, so that the drilling radar antenna can move autonomously back and forth in the horizontal drilling casing. The photoelectric encoder can get the moving distance of the borehole radar antenna in the borehole casing. The communication cable is wound on the reel inside the drilling radar cable receiver. The controller of the cable receiver controls the speed of the reel according to the force information of the cable and the moving distance of the antenna to realize the automatic transmission of the communication cable. send operation. The borehole radar antenna can move autonomously in the borehole casing without human intervention; the cable feeder can automatically deliver and retrieve communication cables without human intervention.

Description

technical field [0001] The invention relates to an antenna automatic detection auxiliary device, in particular to a borehole radar antenna automatic detection auxiliary device used for advanced geological detection of tunnels. Background technique [0002] Borehole radar method is a broad-spectrum electromagnetic technology to determine the distribution of underground media. The transmitting antenna and receiving antenna are placed in the same borehole with a fixed distance. According to the two-way travel time, amplitude and waveform data of the electromagnetic wave at the receiving end, it can be inferred that The structural characteristics of the underground rock-soil medium. The interpretation of the borehole radar is to determine the geological characteristics of the reflected wave group through the tracking of the event axis in the geological radar image section obtained after data processing, according to the waveform and intensity characteristics of the reflected wav...

Problems solved by technology

[0004] However, in the existing borehole radar detection, the way of splicing PVC rods or ropes is often used to deliver and recover the borehole radar antenna. Large error; due to the depth that the borehole radar can detect is very large, the communication cable is very long, and the communication cable is thick and heavy, so in the process of delivery and recovery of the borehole radar antenna, the workload of manually arranging the communication cable is huge

Therefore, the manual operation of the existing borehole radar detection method is complicated and the recording accuracy of the moving distance is not high. There is an urgent need for a set of borehole radar antenna automatic detection auxiliary devices for advanced geological detection of tunnels, which are used for automatic delivery and recovery of borehole radar antennas. Automatically record the moving distance of the borehole radar antenna, and automatically organize the communication cables
