摘要
通过某工程的防渗围井试验,介绍了高压旋喷和高压摆喷围井防渗效果的检验方法,分析了围井前后渗透系数变化,比较了高压旋喷和高压摆喷两种工艺围井的防渗效果的差异,得出了两种工艺的围井防渗效果均能满足要求,且高压旋喷稍优于高压摆喷的结论。
Based on the seepage box well test of one project, the check methods of seepage effect of high pressure rotary grouting and injecting grouting are presented. The permeability coefficients before and after box well are analyzed. At the same time, the differences between two technologies are compared. It is found that the two technologies can satisfy the seepage prevention and the effect of high pressure rotary grouting is better than that of injecting grouting.
