Abstract
The reusable grouting pipe rather than the conventional rigid grout-outgoing box is applied in the contact and backfill grouting of the spiral case in the underground powerhouse, Xiangjiaba Hydropower Project.The reusable grouting pipe features good flexibility, linear grout outgoing at full section and one-direction switchprovided in outer layer, etc.The good grouting result in the underground powerhouse is achieved.It belongs to the scope of new materials, new technology and new techniques because it is rarely applied in con-struction of large-scaled hydropower projects in China.关键词
