摘要
以某隧道横洞与正洞三岔口处的施工为例,在分析施工方案选择与细化的基础上,对横洞与正洞三岔口处的施工步骤、方法与工艺及施工要点进行了论述,实践证明该方案的实施安全、快速地完成横洞进正洞的施工,为隧道贯通打下坚实基础。
Taking the construction at divergence of transverse gallery and the straight tunnel as the example,the paper based on the analysis of the selection of construction schemes and the refining,indicates the construction steps,the methods and craft and the construction points at the divergence of transverse gallery and the straight tunnel,and proves that the scheme has safe implementation and can finish the straight tunnel in transverse gallery,so as to lay the steady foundation for the tunnel link-up.
