Pneumatic Spillway Gate
Air Bag Support Dam/Air Bladder Pneumatic Weir
Structure
The pneumatic spillway gate usually includes water retaining gate, air bladder, between panel connection strip, hinge flap connection strip, control system(pneumatic and electric controlled) and anchoring system.
Operational 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 .
Application
River
The Spillway Gate can regulate the water level of rivers and can be used for water level regulation during flood and dry seasons. Can control overflow and form a waterfall which will improve urban landscape.
Reservoir
Can be used for flood control, water storage, irrigation, and power generation
Underground Garage
Placed at the entrance of the underground garage, it can be used to prevent water from flowing into the underground garage
Road
It can be installed on the side of sidewalks and used as a road surface in daily life. Before floods occur, shield plates are erected and raised to a preset height to solve urban waterlogging
Cold Areas
Because the steel plate protects the independent airbags, it can break ice in stages, allowing ice edges and floating objects to pass through and be used in cold areas
Advantage
1. Simple structure, easy installation.
The unitized and modular structure does not require large construction equipment, saving manpower, materials, and financial resources, and shortening the construction period.
2. It has sufficient safety.
The steel shield plate provides full protection for the rubber dam bag, which can provide sufficient cushioning force and is not afraid of sudden impact from large floating objects.
3. Good ecological landscape effect.
The overflow on the dam will form a waterfall, which is very beautiful.
4. Low management and operation costs.
There will be no jamming during operation, and regular maintenance is not required.
5. Strong ability to clean and dredge.
When the dam collapses, the shield plate completely adheres to the foundation, and the water-blocking height is less than 9 centimeters.
6. Strong seismic resistance.
The shield plate is connected to the foundation with a soft connection, so it will not cause system failure or loss of normal operation capability due to foundation deformation.
7. Wide range of applications.
It is suitable for rivers with complex hydrological conditions and urban beautification projects. It can also be directly applied to the transformation of various rubber dams and automatic flip dams.
