Directly-attached type rock wall deformation laser scanning system and use method thereof

Abstract

The invention discloses a directly-attached type rock wall deformation laser scanning system and a use method thereof. According to the directly-attached type rock wall deformation laser scanning system and the use method thereof, laser distance sensors and light reflection sheets are directly attached and fixed to the rock wall of an excavated underground chamber; displacement monitoring points are automatically scanned under the control of a microcomputer; deformation data are stored; the deformation data are transmitted to the computer; the displacement-time curve of the monitoring points can be quickly and accurately obtained through software analysis; and therefore, the most intuitive and powerful basis can be provided for surrounding rock stability analysis, evaluation, monitoring and early warning, construction, design, operation and the like. Since the system is convenient to install with deep drilling not required, the equipment can perform deformation monitoring immediately after the chamber is excavated, and therefore, deformation loss can be greatly reduced; and the displacement monitoring points are automatically scanned, and the storage displacement data are automatically collected and stored, and therefore, the system are just slightly affected by people. The directly-attached type rock wall deformation laser scanning system of the invention is economical and easy to operate. With the system adopted, problems faced by current displacement deformation monitoring technologies can be solved.

Description

technical field [0001] The invention relates to the field of deformation monitoring of underground engineering surrounding rocks, in particular to a direct-attached rock wall deformation laser scanning system and a use method thereof.
