摘要
三臂凿岩台车作为隧道施工新型工装,广泛试用于公路、铁路隧道、地下洞室开挖等大断面施工工程的掘进开挖、锚杆施工和辅助作业,主要结合工程实际,对三臂凿岩台车在Ⅳ、Ⅴ级围岩两台阶法开挖施工进行应用分析和总结。
As a new type of tunnel construction tool,the three-arm drilling rig is widely used in excavation,anchor construction and auxiliary operation of highway,railway tunnel,underground cavern excavation and other large section construction projects. This paper mainly combines the engineering practice to analyze and summarize the application of the three-arm drilling rig in the excavation construction of Ⅳ、Ⅴ grade surrounding rock by two-step method.
