| 中文摘要:旧堡隧道渗漏为承压条件下的裂隙渗漏，主要表现在局部道床和局部边墙结构缝处的渗漏。该线经多年通车运行渗漏现象日趋加重，表现为夏季道床局部积水湿滑和边墙侧行走板的渗漏湿滑。采用疏、堵相结合的工艺进行治理，即采取新钻导水孔引导边墙砌体外承压水至集水井内的疏导方法和在裂隙渗漏区植管注胶堵漏的方法，收到了良好的效果。 |

| Abstract:Jiubu tunnel leakage is of fissure seepage under pressure conditions, mainly for seepage at local ballast bed and local sidewall structural joints. This railway line has been put into traffic operation for years, the leakage is increasing day by day. In summer, ballast bed wet traction caused by local water accumulation and walking board wet traction caused by seepage at side wall would appear. The combined process of dredging and plugging is adopted, that is by drilling water conducting hole to lead the confined water out of the side wall masonry to the collecting wells and setting tubes to inject glue for plugging, good results have been achieved. |
