Exploration method capable of detecting cross-section changes of tunnel and positioning detection result

Abstract

The invention discloses an exploration support, an exploration apparatus and an exploration method which are intended for detecting geology of the surrounding rock of a tunnel. The exploration apparatus includes a laser range finder, a LTD ground penetrating radar and an exploration support. The exploration support includes a mobile support, an axial rotation support, a radial rotation support and a driving apparatus. The radial rotation support is disposed on the mobile support, and rotates cooperatively with the mobile support. The radial rotation support and the axial rotation support intersect in a crossed shape. The radial rotation support is telescopic along the axial direction thereof. The driving apparatus drives the axial rotation support to rotate and drives the radial rotation support to rotate. According to the invention, compared with prior art, the exploration support, the exploration apparatus, and the exploration method are advantaged by capabilities of continuously and accurately exploring the cross-section of the tunnel, accurately positioning the detection result, and being supportive in forming a 3D geological change graph of the surrounding rock of the tunnel in a region in an accurate and efficient manner.

Description

[0001] This application is a divisional application with an invention title of exploration support, exploration device and exploration method for detecting roadway surrounding rock geology, application number 201510608717.9 (application date September 21, 2015). technical field [0002] The invention relates to the field of roadway surrounding rock exploration, in particular to an exploration method capable of detecting roadway section changes and positioning detection results. Background technique [0003] The surrounding rock of the roadway is an extremely complex geological body, with complex and changeable rock strata, and various complex geological structures such as faults and folds. All work related to the surrounding rock, such as working face mining, roadway layout, roadway support design, etc., Both are inseparable from a full understanding of the geological characteristics of the surrounding rocks in the region. The ground-penetrating radar system transmits high-f...

AI Technical Summary

Problems solved by technology

At present, the ground-penetrating radar exploration device for geological changes in the surrounding rock of the roadway in the region has the following shortcomings: the existing exploration device generally uses manual push-pull, which is labor-intensive and labor-intensive; in addition, the change of the roadway section during the continuous detection process is not fully considered. The exploration process is unstable, and it is impossible to conduct continuous and accurate exploration of the roadway section; in the existing exploration operation, the layout of the survey line is small, and the detection results of the roadway section cannot be accurately positioned; the surrounding rock of the roadway can not be formed through the existing exploration equipment.
