公伯峡水电站土石围堰防渗布置与施工

Arrangement and construction of seepage control for rock-earth cofferdam of Gongboxia Hydropower Station

公伯峡水电站土石围堰布置 5种防渗型式 ,分别是沥青防渗墙、现浇混凝土防渗墙、粘土心墙、土工膜防渗和高压旋 (摆 )喷混凝土防渗墙。通过对不同类型防渗墙的施工方法、施工程序和防渗效果的比较 。

There are five types of seepage control for the earth rock cofferdams of the Gongboxia Hydropower Station, that is, asphalt impervious wall, cast in situ concrete impervious wall, clay core wall, geomenbrane impervious wall and high pressure rotation spraying concrete impervious wall. This paper describes detailed the construction methods and processes and the impervious effectiveness of different types of impervious walls. Through the comparison, it can be used for the design and construction of other similar projects for reference.
