Abstract

The invention discloses a direct-attached rock wall deformation laser scanning system and an application method thereof. In the present invention, a fixed laser distance sensor and a reflective sheet are directly pasted on the rock wall of the excavated underground chamber, controlled by a microcomputer, automatically scanning displacement monitoring points, storing deformation data, and finally transmitting the deformation data to a computer for software analysis. It can quickly and accurately obtain the displacement-time change curve of the monitoring point, and provide the most intuitive and powerful basis for the analysis and evaluation of the surrounding rock stability, monitoring and early warning, construction, design, and operation. Due to the convenient installation and no need for deep drilling, the equipment can monitor the deformation immediately after the excavation of the cavern, which greatly reduces the loss of deformation; in addition, due to the automatic scanning of displacement monitoring points, the automatic collection and storage of displacement data, thus It is less affected by personnel, and the present invention better solves the problems faced by the current displacement and deformation monitoring technology, and is economical and easy to operate.

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. Background technique [0002] With the rapid development of my country's national economy and the in-depth development of the western region, the development and utilization of underground space has entered a new stage of development. Underground engineering mainly refers to passages and various types of underground buildings built in rock mass or soil layers, including railways, roads, canal tunnels, underground railways and underwater tunnels in transportation; municipal and air defense projects in industry and civil , underground engineering for mining, storage and production purposes; various national defense tunnels for military purposes; underground chambers, power plant rooms and other hydraulic tunnels for hydroelectric power generation...
