根据渗水的速度将油性聚氨酯堵漏剂和水性聚氨酯堵漏剂按一定比例混合使用于处理溢流堰表面裂缝渗水的实例中，通过实践证明了两者混合使用不但取得了很好的止水效果，还保证了工程的使用寿命和功能。%According to the speed of the leakage water, the paper illustrates the oily and water-based polyurethane plugging agent mixture in cer-tain mixing proportion to deal with the leakage of cracks of the downflow bay, and proves by the practice that the mixture can achieve better wa-terproof effect and ensure the use lifespan and the functions in the projects.
