摘要:
针对隧道工程钻爆法开挖过程中钻爆设计图形放样、初期支护拱架安装定位精确度不高的问题,通过分析国内外隧道工程开挖与初期支护采用的测量放样技术,提出基于激光的全自动测量放样技术方案,并研发了配套设备。工程试验结果表明,该技术及配套设备,具有安装使用简单、运行安全可靠、定位精准等特点,能够发挥隧道开挖及初期支护全自动化快速施工测量放样的技术优势。

Abstract:
During tunnel excavation with drilling and blasting method, drilling and blasting design lofting and primary support arch installation are often not accurate enough. Hence, measuring and lofting technology used in tunnel excavation and primary support in China and abroad is analyzed, a scheme of fully automatic measuring and lofting technology based on laser is put forward and some matching equipment are developed. The engineering test shows that the measuring and lofting technology and its matching equipment are characterized by simple installation, reliable and safe operation, precise positioning, etc., which can help realize the rapid and automatic measuring and lofting of tunnel excavation and primary support.
Key words: tunnel engineering, measuring and lofting, laser, automation, Big Dipper laser image locator
