摘要
基础产生渗漏不仅影响到施工的正常进行,还可能威胁到建筑物的稳定,因此通常需要灌浆形成防渗帷幕来控制渗流.常规水泥浆、水泥粘土浆、砂浆甚至低级配的混凝土对于高流速、大流量的渗漏地层,其堵漏效果一般都不显著.结合广西某水电站坝基堵漏工程,对水泥膏浆和速凝膏浆技术进行了系统的研究,为中等开度、一定流速的动水裂隙堵漏灌浆提供了一种新材料、新工艺.
The seepage in the foundation of dam has influence on not only the construction , but also the stability of building. So grouting usually was used to control the seeping. The anti-seeping effects of cement slurry, cement-clay slurry , cement-sand slurry and also low-grade concrete to be used in the seeping-stratum with high-rate, large discharge,are generally not good. In this paper , the cement paste-slurry and quick coagulating cement paste-slurry technology were be studied, and used in the anti-seepage project of one foundation of dam in Guangxi province. This technology is a new material and technology to anti-seeping grouting in the seeping-stratum with medium opening and medium rate moving-water.
