| Abstract: | The installation technique of channel check valve is introduced by taking the example of Hebi section,the second construction section of South-to-North Water Diversion Project. The technique are in accordance with following orders： foundation excavation,backfilling the first layer of coarse sand,burying water collecting pipe,backfilling coarse sand surrounding pipes,laying warm keeping board,laying composite geomembrane and installing check valve. Meanwhile,the quality control methods,such as control check valve installation position,elevation and quantity are also covered. |
