Operation Principle
- Raising Dam: The air bag is inflated to support the water shield plate to realize the water storage operation.
- Overflow: When water level exceeds the gate panel height, flow crosses the panel; air bladder and support systems are hidden safely underneath.
- Height Adjustment: Support angles are managed by adjusting inflation pressure to control required water retaining height.
- Dam Collapse: By discharging the air bladder, the gate lies flat on the riverbed, protected from sharp floating objects.
- Dual Control: All operations are equipped with manual and automatic "dual control" systems.
Structure & Key Features
The ecological spillway gate includes water retaining gate panels, air bladders, connection strips, hinge flap connection strips, control systems (pneumatic and electric), and anchoring systems. It features gate height adjustment, aeration devices to remove sediment, and biological channels for environmental protection.
