。Air Shield Rubber Dam is a flexible hydraulic building combining rubber dam and shield-shaped water retaining structure, mainly used for river water storage, flood control and regulation and ecological maintenance. Its core functions include: 1. flexible water level adjustment, through the filling and draining control dam height, to adapt to different flow requirements; 2. flood control and discharge, rapid collapse of the dam discharge, to protect the safety of downstream; 3. ecological protection, to reduce the destruction of the river ecology of the hard engineering; 4. durable and economical, rubber material corrosion resistance, low maintenance costs. Suitable for urban landscape, irrigation and small and medium-sized water conservancy projects, both functional and environmentally friendly.
