【摘要】：结合二郎山特长公路隧道工程实例,文章针对隧道施工中遇到的难题,提出了在斜井对主洞掘进任务起不到辅助作用时,通过主洞反向施工斜井的施工方案。文章重点阐述了联络通道上跨主洞、地下风机房挑顶、各交叉口施工、斜井出洞等关键施工技术,可为今后类似隧道工程的施工提供参考。
[Abstract]:Based on the practical example of Erlangshan Extra-long Highway Tunnel, the paper puts forward the construction scheme of inclined shaft construction through the reverse construction of main tunnel when the inclined shaft does not play an auxiliary role to the main tunnel driving task, in view of the difficult problems encountered in tunnel construction. This paper focuses on the key construction techniques, such as crossing the main tunnel, lifting the roof of the underground fan house, each intersection construction and the inclined shaft exit hole on the contact passage, which can provide a reference for the construction of similar tunnel projects in the future.
