1.Introduction:
The weir is “pneumatic spillway gate system that utilizes air as a medium to raise the gate system and allow water to pass over the top of the gate panel. The system shall include gate panel(carbon steel or stainless steel ),air bladder(EPDM rubber with reinforced polyester),anchorage system, control system ,air compressors.

2. Operation Principle:
Retaining water ,Cover flow ,Adjust the dam height ,Collapse

3. Advantage compared to inflatable rubber dam:
Lifespan is longer ,more than 35 years
More ecological and environmental protection
Double air bladder can realize higher height
4.Usage:
Flood protection
Segment
Small hydropower generate power
Water storage and supply
Irrigation
5. Laboratory corner

6. Workshop corner
