隧道开挖施工中,施工机械配置、工序作业时间和工序衔接等对工程进度影响很大。以月直山隧道施工为例,其为实现快速掘进,采用了三臂凿岩台车,并研究了其改造、爆破参数等内容,在实际运用中显著提升了施工速度,并有效保证了安全。月直山隧道进口里程DK239+915,出口里程DK254+000,全长14085m,单洞双线。进口接路基,出口接依布双线大桥,另金口河车站伸入隧道进口端,
In tunnel excavation construction, the configuration of construction machinery, operation time of work process and process connection have a great influence on the progress of the project. Taking the construction of the Yueshan Tunnel as an example, this project adopted a three-arm rock drilling rig to realize rapid heading and studied the rebuilding and blasting parameters. The practical application greatly enhanced the construction speed and ensured the safety . Month straight mountain tunnel entrance mileage DK239 +915, exit mileage DK254 + 000, full-length 14085m, single-hole two-lane. Imported roadbed, exports followed by double-track bridge, and the other Jinchuanhe station into the tunnel entrance,
