As an innovation hydraulic structure, the pneumatic spillway gate project mainly consists of rubber bladder, steel gate panel, anchor fittings, control system and ect.It is most simply described as a row of steel gate panels supported on their downstream side by inflatable air bladders. By controlling the pressure in the air bladders, the pond elevation maintained by the steel gate panel can be infinitely adjusted within the system control range (full inflation to full deflation) and accurately maintained according to customers’ requirement. The spillway gate system is attached to the foundation structure by anchor bolts and clamps. There are an equal number of air bladders and gate panel sets.

Advantages:
Compare to the traditional dam, the pneumatic spillway gates are low cost, easy maintenance. It combines advantage of conventional steel gate and rubber dam, which can not only meet the requirement of safety of retaining water adjustment of discharging water level, but also enhance the beauty of environment.
1. Simpler structure and installation. Modular design can save more manpower, time and money
2. Steel panels protect the rubber bladders from damage, which could extend the service life.
3. Can operate with higher values of overtoping to improve the landscape
4. Lower operation cost. No need frequent maintenance and repair.
5. Easier for desilting. The steel panel could fit snugly on the concrete foundation in deflation status.
6. Higher seisemic resistance. It is hardly affected by the transformative foundation
7. More extensive application scope. It can be built in a variety of rivers
8. It could modify the rubber dam in original concrete foundation to reduce the cost.

Gate panel
Material: stainless steel, carbon steel
Size: 5m or 6m per unit
Structure: made of steel panel above 16mm thickness, arc, reinforced ribs on the surface
Corrosion protection: hot galvanized or zinc or polyurea material.
Air bladder
Material: Air bladder is made of tyre fabrics and synthetic rubber with good property of abrasion resistance heat resistance and ozone resistance.
Performances: Working pressure 0.07-0.20MPa, safety factor:8-10times
Anchor system
The anchor system includes anchor plate and anchor bolt. The steel gate panel and rubber bladder are fixed to the concrete foundation by the anchor system . The clamping plate is made of casting steel and the anchor bolt is made of cold drawing steel or stainless steel
Inflation &Control system：
The inflation system includes the air blower and air pipe. The air pipe can use the rubber hose or PPR pipe to bury in the concrete foundation. The control system includes PLC, human interface, liquid level sensor, pressure transmitter, transducer, and ect. It can be divided into manual control system and automatic control system.
