一、前言水溶性聚氨酯注浆材料是一种新型单组合高分子注浆堵漏材料,它与水聚合后的固结体具有良好的延伸性、弹性及抗渗性,故可用来处理刚性防水法不能奏效的混凝土建筑物伸缩缝漏水问题.如在伸缩缝外侧表面采用可以变形的851涂膜橡胶作第二道止水措施,止水效果则更加可靠.这种处理方法施工方便,造价较低,效果较好,不仅可用于伸缩缝防漏处理,还可以广泛应用于水工建筑物施工缝、结构裂缝的渗漏处理.特别是在潮湿的或有流动水的场合,更显示出优越性.
I. Introduction Water-soluble polyurethane grouting material is a new single-grouting polymer grouting material, which has good extensibility, flexibility and impermeability with the water-polymer consolidation, it can be used to deal with rigid waterproof Law can not work for the expansion of concrete structures leaking problems such as the outer surface of the expansion joints can be deformed 851 coated rubber as the second water stop measures, the water stop effect is more reliable.This method of handling construction easier, more cost Low, good effect, not only for the expansion joints leak-proof treatment, but also can be widely used in hydraulic construction joints, cracks in the structure of leakage treatment. Especially in wet or flowing water occasions, but also shows the superior Sex.
