摘要
银盘水电站二期围堰地质条件复杂,防渗工程量大、工期短,施工强度大,施工中采用了以水泥膏浆为主要灌注材料的可控性灌浆为主。结合高压旋喷灌浆的防渗施工方案,利用两种工法的各自特点,相互补充,解决了单一防渗工艺对不同地层防渗效果的局限性,达到了围堰快速闭气的目的。
The geological condition for the Phase II earth-rockfill cofferdam for construction of Yinpan Hydropower Station is complicated,for which the anti-seepage construction quantity is larger with shorter construction period and heavier construction intensity.During the construction,combined with the anti-seepage construction scheme of high-pressure rotating grouting,the controlled grouting is mainly adopted with the main grouting material of the cement plaster,and then the problems from the limitation of the anti-seepage effect on various strata from only a single anti-seepage technology are solved by the utilization of each characteristics of both the construction methods.
