铁路隧道渗漏水的原因分析与防治

Cause Analysis and Prevention of Leakage in Railway Tunnel

随着我国脱贫攻坚的快速进程,很多地处偏远、地形崎岖的山区已经或都在铺设铁路,隧道作为铁路运行的重要基础设施,铁路隧道工程也越来越多。对铁路隧道工程质量的要求也越来越高,使得铁路隧道施工技术和病害问题日益成为铁路施工技术人员关注的热点。在铁路隧道工程中,渗漏水是比较典型和常见的病害问题,不仅会影响隧道洞内通讯及照明设备的正常运行,造成设备失效和短路;长期严重的渗漏水还会导致洞内衬砌混凝土的腐蚀损坏,降低其支承和围护能力,影响隧道结构的安全。鉴于铁路隧道渗漏水的严重危害,广大铁路维护人员一定要做到早发现、早治理,以保证铁路隧道的正常通车运行。

With the rapid progress of poverty alleviation in China,many remote and rugged mountain areas have been or are laying railways.Tunnels are an important infrastructure for railway operation,and there are more and more railway tunnel projects.The requirements for the quality of railway tunnels are becoming higher and higher,making railway tunnel construction technology and disease problems increasingly becoming the focus of attention of railway construction technicians.In the railway tunnel project,water leakage is a typical and common disease problem,which will not only affect the normal operation of the communication and lighting equipment in the tunnel,causing equipment failure and short circuit;Long-term severe water leakage will also lead to corrosion damage to the lining concrete in the tunnel,reduce its support and enclosure capacity,and affect the safety of the tunnel structure.In view of the serious hazards of water leakage in railway tunnels,the majority of railway maintenance personnel must do early detection and treatment to ensure the normal operation of the railway tunnel.
