摘要
引洮供水工程是以隧洞为主的引水工程,隧洞开挖进度是控制施工工期的瓶颈。通过阐述泥岩隧洞施工前期采用传统钻爆法进行开挖施工中出现的一些问题,从不同方面对传统钻爆法和铣挖机开挖法进行对比分析,决定将隧洞施工工艺由传统钻爆法调整为铣挖机开挖法,施工安全高效,可供类似工程参考。
Yintao water supply project is a tunnel diversion project,tunnel excavation progress is the bottleneck to control the construction period. Expounds on shale tunnel construction prophase the traditional drilling and blasting method is adopted for the excavation construction of some of the problems,and never tongfang facing the traditional drilling and blasting method and the milling drivers excavation method,this paper compares and analyzes decided to tunnel construction process from the traditional drilling and blasting method is adjusted for milling drivers excavation method,construction safety and efficiency,good stability during construction.
