摘　　要：某港口工程监测资料揭示防渗墙墙下存在渗透通道,采用墙下灌浆措施成功治理了渗漏通道。对本工程防渗墙墙下堵漏处理的设计及施工关键技术要点进行总结,囊括防渗标准、堵漏范围确定、灌浆孔平面布置、灌浆深度、灌浆分段、灌浆压力、灌浆工艺等方面,形成一套完整的防渗墙墙下堵漏处理技术。采用水位观测确定堵漏范围的方法突破了旧有技术,可为后续项目提供参考。In a port engineering project,monitoring data reveal the presence of leakage channels under the cut-off wall.Grouting under the wall has been proven highly effective against the leakage.The key technical points are summarized regarding the design and construction for the leakage treatment under the cut-off wall in the project,encompassing the anti-leakage standard,determination of the sealing range,layout of grouting holes,grouting depth,grouting sections,grouting pressure,and grouting technology.Taken together,they form a set of technology for the treatment of leakage under cut-off walls.The sealing range determination based on water level observation breaks through the traditional technology,which can provide a reference for subsequent projects.
