OPERATION PRINCIPLE
1. Raising Dam: the air bag is inflated to support the water shield plate to realize the water storage operation;
2. Overflow: when the water level exceeds the height of the gate panel, the water flow and floating objects cross the panel, and the air bladder and support system are hidden under the gate panel to be fully protected;
3. Dam height adjustment: adjust the support angle of gate panel by adjusting the inflation pressure to control the required water retaining height;
4. Dam collapse: by discharging the air bladder, the gate panel and air bladder lie flat on the concrete foundation of the riverbed floor, and the support system is completely covered by the gate panel, so the rubber air bladder under the safe condition to avoid damage by the sharp floating object.
5. All the above operation are equipped with manual and automatic "dual control" system.
STRUCTURE
The ecological spillway gate mainly includes water retaining gate panel, air bladder, between panel connection strip, hinge flap connection strip, control system (pneumatic and electric controlled) and anchoring system. lt is characterized in that the main body of the spilway gate is equipped with a gate height adiustment and restraining device, the front of the dam is equipped with an aeration device to remove sediment, and a biological channel is set at the bottom of the dam, which has many advantages such as perfect structure and ecological environment protection.
Unique features
1. Accurate water level control;
2. Modular structure, easy installation and maintenance;
3. The air bladder is fully protected by gate panel in all directions, and is not damaged by water, sediment, rolling stones, floating objects and ice edge (including strong ultraviolet radiation), and its service life is longer;
4. Scientific supporting structure, safe and stable operation;
5. It can fully meet the design requirements of 8-10m dam height;
6. The trajectory bucket type energy dissipation is good: the water flow is even and the overflow drop is large, which can form a more magnificent waterfall landscape;
7. lt can be directly reconstructed on the old foundation and weir crest such as rubber dam and concrete flap dam, which can greatly reduce the cost of reconstruction project.
