| 摘 要： | 太平江水电站厂房围堰为深厚砂卵石覆盖层,且夹含砂壤土及漂石,防渗性能极差,在围堰防渗施工前,进行钻孔勘探,探明了防渗轴线的实际地质情况,选择了高压旋喷灌浆为主的防渗方案,并进行高喷灌浆试验,选定合理的施工参数,实现了高喷施工速度快、防渗效果佳的目的,保证了厂房基坑施工的顺利进行。

| Abstract: | The cofferdam of power house at Taipingjiang Hydropower Station is built on thickly bedded sandy gravel overburden layer mixed with sandy loam and erratic stone that has unfavorable anti-seepage property.Before anti-seepage engineering of the cofferdam,holes are drilled to investigate geologic conditions of anti-seepage axis.Anti seepage is mainly achieved through high pressure jet grouting.As rational construction parameters are defined through test of high pressure jet grouting,the grouting works fast and... |
