随着隧道施工机械化程度的提高,在特长小断面隧道工程中采用钻爆法掘进施工时,机械配套是制约掘进速度的重要条件。文章介绍了西康线秦岭隧道Ⅱ线平导进口工区,在分阶段采用不同的机械配套的条件下,发挥了配套机械的整体工作效能,给类似工程提供了一个典型实例。
With the improvement of mechanization of tunnel construction, when using the drilling and blasting method to excavate the tunnel in the special small section tunnel, the mechanical matching is an important condition to restrict the tunneling speed. This article introduced the second line of the Qinling Tunnel of Xikang Line, which leads to the second-line flat-lead import work area. Under the condition of using different mechanical equipment in stages, the overall work efficiency of the auxiliary machinery is exerted, providing a typical example for similar projects.
