军都山隧道采用世界先进水平的机械化施工,大大减轻了工人体力劳动强度,湿式凿岩时,岩尘污染已达到国家容许浓度。然而,施工中采用机械掘进深孔爆破、干喷混凝土、聚氯乙烯防水板以及无轨运输等技术,使作业环 Jundushan tunnel adopts the most advanced mechanized construction in the world, which greatly reduces the labor intensity of workers. When wet rock drilling, the rock dust pollution has reached the national allowable concentration. However, the use of mechanical tunneling deep hole blasting, dry shotcrete, PVC waterproofing board and trackless transportation technology, so that the ring operation
