近几年来,随着我国国民经济的发展,在铁路隧道施工方面不断引进国外的先进技术和施工设备,象京广复线的大瑶山隧道引进了四臂台车开挖,三联机喷射混凝土拱墙灌注模板台车作业,混凝土拌合工厂化和无轨运输一条龙的隧道施工生产线,大幅度地提高了劳动生产率,使隧道施工有了新的发展和进步。目前,由于我国经济还比较落后,铁路隧道修建不可能全都实现全机械化施工。当前,一些隧道施工仍处于小型机具和部分机械施工的状况即:7655风动凿岩机打眼,装碴机、电瓶车运输,斗车或比斗车,运
In recent years, with the development of our country’s national economy, we have introduced advanced foreign technology and construction equipment in the construction of railway tunnels. Dayuashan Tunnel, like the Beijing-Guangzhou double-track railway, has introduced a four-arm trolley excavation and a triple jet squirting concrete arch Wall perfusion template trolley operation, concrete mixing plant and trolley transport tunnel construction production line, greatly improving the productivity of the work, the tunnel construction has made new development and progress. At present, due to China’s economy is still relatively backward, the construction of railway tunnels can not be fully mechanized construction. At present, some tunneling construction is still in the condition of small machinery and some mechanical construction, namely: 7655 pneumatic rock drilling machine drilling, ballast loading machine, battery car transport, bucket car or bucket car
