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
