正井法在通风竖井施工技术应用

Application of Normal Shaft Method in Ventilation Shaft Construction Technology

介绍了3号通风井施工在小断面尺寸竖井及联通隧洞施工的布置。竖井及联通隧洞出渣的设计方法,该开挖方案满足“L”型通风竖井施工,有效解决了通风竖井与主隧洞交叉施工影响,提高了整体工程建设进度。

This paper describes the construction arrangement of No.3 ventilation shaft in light section size shaft and connecting tunnel,and the design method of shaft and connecting tunnel slag discharge.The excavation scheme satisfies the construction of L-type ventilation shaft,effectively solves the cross-construction effect between ventilation shaft and main tunnel,and improves the overall construction progress.
