利用隧洞掘进机进行隧洞施工,其施工组织内容主要有主机设计,电力、后配套与运送列车,掘进效率与工期,施工人员配备,施工方法及工艺,施工场区规划。通过山西万家寨引黄工程7号隧洞施工的实例,对掘进机法和钻爆法两种施工方法进行了经济比较以及综合经济效益比较。分析表明,在适宜掘进机施工的地下工程中,采用掘进机施工可以减少工程量、增加安全性、提高效率,经济效益良好,具有很大的优势。
Tunnel construction using tunnel boring machine, the main construction content of the host design, power, after the supporting and transporting trains, driving efficiency and duration, construction staffing, construction methods and processes, construction site planning. Through the example of tunnel construction in No.7 tunnel of Wanjiazhai Yellow River Diversion Project in Shanxi, economic comparison and comprehensive economic benefit comparison between two road boring machines and drilling and blasting methods are carried out. The analysis shows that it is of great advantage to reduce the engineering quantity, increase the safety, improve the efficiency and have good economic benefits when using the boring machine in the construction of appropriate underground machines.
