近年来,在修建山体岩石隧道中,越来越广泛地使用隧道掘进机进行机械化施工。使用隧道掘进机,可以保证开挖、出碴实行全盘机械化,开挖周边平整,掘进速度高,施工劳动量及工程费用降低。
In recent years, more and more tunnel boring machines have been used for mechanized construction in the construction of mountain rock tunnels. The use of tunnel boring machine, you can ensure excavation, ballast to implement a full mechanization, excavation around the formation of high speed, high construction, construction and labor costs reduced.
