| Abstract: | To repair the emergency gate at the bottom scouring sluice No.10, we adopt floating gate system to block the bottom outlet automatically in 60 m underwater to make the repair construction in the dry, which proved to be successful. This paper briefly introduces the key technologies used, along with its features, applicable evaluation and commercial prospective in hydropower sector. |
