摘要
结合赵山渡水库大坝浅槽区闸墩喷射性漏水的情况,加固工程采取分阶段施工,分别进行施工缝和伸缩缝、防渗墙处理。施工方案制定严谨,过程中工艺灵活,技术上采用加固止水、水下灌浆等措施,成功完成了对重力坝施工缝及防渗墙漏水的修复加固。
Aimed at the leakage at the pier of Zhaoshandu reservoir dam, stages of treatment were car-fled out, namely the treatment of construction joint, expansion joint and cutoff wall. By application of measures such as rehabilitation, water sealing and underwater grouting, the treatment was completed and good effect was achieved.
