沿海地区地下通道墙体防水与堵漏施工技术

Construction Technology of Waterproof and Plugging of Underground Tunnel Wall in Coastal Area

沿海地区地下通道工程由于地下水位高,其墙体防水和堵漏非常重要。结合秦皇岛某工程,分析了墙体渗漏水原因,采取了针对性措施,并用重点注浆法处理漏水,取得了良好效果。

Waterproof and plugging of underground tunnel wall in coastal area are important due to high water level.Based on a project in Qinhuangdao,leakage causes are analyzed,and corresponding countermeasures are adopted.Moreover,grouting method is selected to prevent leakage.Then,good waterproof effect is gained.
