微硅粉应用于砂性地层注浆工程的可行性分析

Feasibility Analysis of the Silica Fume Applied to Grouting Engineering in Sandy Strata

在渗透注浆工程中,尤其在中、细砂地层中,提高浆液的可注性并保证一些特殊工程的耐久性非常重要。微硅粉作为注浆材料,其颗粒极细,可注性好,无毒性,浆液结石体强度高,工程耐久性好。通过对一些工程的成功应用进行分析,微硅粉可以作为一种很好的渗透注浆工程注浆材料,尤其在高水位,含中、细砂层地质条件下,微硅粉注浆材料具有广阔的工程应用前景。

It is very important to improve the groutability and the durability of grouting material applied to grouting engi- neering, especially in medium and fine sand formation. Silica fume is a grouting material with fine grain, good groutability, no-toxicity, high concretion strength and good durability. By the analysis on successive applications, silica fume is intro- duced in the use of grouting engineering, especially in medium and fine sand formation.
