牡绥铁路双丰隧道富水第三系砂泥岩地层超前注浆加固施工技术
Construction Techniques of Pre-grouting in Tertiary of Rich-water Sand-shale in Shuangfeng Tunnel on Mudanjiang-Suifenhe Railway
摘要
Abstract
Shuangfeng Tunnel is the longest tunnel and the key controlling project of Mudanjiang-Suifenhe Railway. About 2. 3 km of the tunnel passes through tertiary sand shale and contact zone with other rock strata. The diagenesis of tertiary sand-shale is of poor quality in part of soft rock and the tunnel is deep-burial with gentle topography. Plenty of water is gathered in the contact zone of the tertiary sandstone and other rocks. The groundwater in this area is characterized by large amount and far uneven in supply source and spatial distribution, which may result in big tunnel deformation, tunnel collapse, water Inflow and soil leakage, and make tunnel construction very difficult. According to this circumstance, the method of full face advance grouting reinforcement after upper bench excavation is employed. By comprehensive effect evaluation and construction test, this method is proved to be effective in strengthening the rock and ensuring safe and successful tunneling.关键词
