摘要
水工混凝土水下裂缝渗漏处理很困难,丹江口混凝土坝深水裂缝防渗修补,采用了水溶性聚氨酯,防渗效果显著。本文简单介绍了聚氨酯性能、化灌处理过程和防渗处理前后渗漏量的变化等情况。
It is difficult to treat crack seepage underwater.In Danjiangkou project,water-soluble polyurethane has been adopted to re-pair the crack on concrete dam under-deep-water,This paper briefly introduces the property of polyurethane,treatment processing of chemical grouting and change of seepage amount before and after repair.
