电力隧道渗漏水成因分析及治理措施研究

Analysis and Treatment Measures of Water Leakage in Power Tunnels

电力隧道内电缆数量较多,电缆及其他电力设施对水非常敏感,如果积水淹没电缆(尤其是电缆接头部位),可能会造成事故和损失。文章详细分析了暗挖、盾构等结构形式隧道的渗漏水成因,对管片、环梁、沉降缝、墙体及管孔等部位渗漏水治理措施进行研究,提出了针对性的治理建议并进行了试点应用,为电力隧道渗漏水治理工作提供参考。

There are many cables in the power tunnel,power cables and other power facilities are very sensitive to water.Although many waterproof measures have been taken for the high-voltage cable body,accidents and losses may be caused if ponding inundates the power cable(especially the cable joint).This paper analyzes the causes of water leakage in tunnels with concealed excavation,shield and other structural forms in detail,studies the treatment measures of water leakage in segments,ring beams,settlement joints,walls and pipe holes,gives targeted treatment suggestions and introduces the application.Provides reference for the long-term work of water leakage treatment of power tunnels.
