双连拱隧道中隔墙渗漏水的治理

On the Treatment of the Water Percolation in Partition Walls of the Double Multi-arch Tunnel

针对某隧道施工中出现的隔墙渗漏水问题,分析了产生原因,对已施工过程和未施工段采取不同的治理措施,加强施工质量管理,提出设计方案的改进建议,治理效果良好,可为类似工程提供参考。

The techniques for the treatment of water percolation in the intermediate partition wall of a certain tunnel are introduced in the paper, with some improving suggestions for the construction and design put forward. On the. basis of intensifying the quality control, not only are the water percolation and leakage in the previous built sections properly dealt with but also those of the intermediate partition walls of the following built sections are prevented, which helps achieve good results. With the water percolation in the intermediate partition wall of a certain tunnel aimed at, the causes are analyzed and different effective treating measures respectively for the finished sections and the sections to be built are put forward.
