大纵坡隧道富水区及软弱围岩注浆技术探讨

Discussion on Grouting Technology in Water-rich Area and Soft Surrounding Rock Longitudinal Slope Tunnel

文中以弥玉项目登楼山隧道2"斜井为背景,分析了穿越富水断层破碎带施工过程中遇到的各种不利情况及处理措施,总结了隧道穿越大纵坡富水区及软弱围岩注浆快速施工技术经验,以期为此类隧道施工提供参考。

Taking dengloushan tunnel 2#inclined shaft of Miyu project as the background,this paper analyzes various adverse conditions and treatment measures encountered in the construction of crossing water rich fault fracture zone,and summarizes the technical experience of rapid grouting construction of tunnel crossing large longitudinal slope water rich area and weak surrounding rock,in order to provide reference for such tunnel construction.
