【摘要】:結合二郎山特長公路隧道工程實例,文章針對隧道施工中遇到的難題,提出了在斜井對主洞掘進任務起不到輔助作用時,通過主洞反向施工斜井的施工方案。文章重點闡述了聯(lián)絡通道上跨主洞、地下風機房挑頂、各交叉口施工、斜井出洞等關鍵施工技術,可為今后類似隧道工程的施工提供參考。
[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.
