摘　　要：本文中该工法提出了悬臂式纵轴掘进机开挖与轴流风机负压抽风、激光导向仪定位放样辅助的配套使用模式,重点介绍了悬臂式纵轴掘进机在小断面、长隧洞开挖中的施工工艺流程及操作要点,为类似工程施工提供参考。In the paper, the matched application mode of cantilever vertical shaft type tunneling machine excavation, axial flow fan negative pressure convulsion, and laser alignment telescope location lofting auxiliary measures is proposed for the method. The construction process flow and operation keys of cantilever vertical shaft type tunneling machine in small section and long tunnels excavation are mainly introduced, thereby providing reference for construction in similar projects.
