Tunnel radio laser laying out apparatus

Abstract

The invention discloses a wireless laser lofting device used in tunnel which is composed of the computer, the servo electrical total station, the semiconductor laser and the wireless communication processor. The computer serial port is connected with the wireless communicator; the total station is connected with the wireless communicator by the serial port; the semiconductor laser is installed in the ranging turn part of the total station. The system can locate and input the tunnel axis line data, the digging cross-section and the drilling scheme data controlled by the computer software; also it can measure the cross section and loft in the cross section outline, the cannon hole location. The device can deal the random curve tunnel, the cross section form and the drill scheme to monitor the digging by the laser. So it is proper for every underground project including the tunnel.

Description

technical field [0001] The invention relates to a laser stakeout device for underground engineering excavation, more particularly to a wireless laser stakeout device for tunnels, in particular to a laser stakeout device for excavation section outline and blasthole positioning stakeout in drilling and blasting tunnel construction. Background technique [0002] At present, in the drilling and blasting method construction of underground tunnel network, the positioning and staking of the excavation face is generally in the state of manual instrument centerline measurement and steel ruler positioning of the blasthole, which is time-consuming and labor-intensive, and has low work efficiency, which cannot meet the huge engineering tasks. The urgent requirement of time, and the poor positioning and lofting accuracy are likely to cause excessive and under-excavation, affecting the construction quality, progress and cost. [0003] Using laser projection for st...

Problems solved by technology

This type of technology and corresponding instruments have some disadvantages in practical application: self-positioning is difficult, requires the cooperation of measuring instruments, and it is difficult to freely set up stations. For example, it can only be placed on the middle pile point, which occupies the tunnel traffic space and affects Tunnel construction; it is inconvenient to deal with curved tunnels; due to the limited relative aperture of the objective lens, the scanning range and distance are limited. For example, if the tunnel section that needs to be set out is large, the set-out instrument must be far from the excavation face
