What are the performance indicators and structural characteristics of domestically manufactured air-shield dam gate systems in China?
1. Water level can be regulated either manually or automatically. In particular, water level and flood discharge remain controllable by exhausting air from the air bags even during power outages caused by flood surges. The gate can function normally after flood release despite sludge and sundry deposits on its surface.
2. The modular design facilitates streamlined installation and uninterrupted construction without intermediate piers. Featuring a relatively simple lightweight structure, the product delivers easy maintenance and excellent seismic resistance.
3. The airfoil gate body enables unobstructed passage of water flow, ice blocks, driftwood and gravel. Reinforcing plates integrated on the gate double as flow deflectors to smooth water flow and mitigate erosion.
4. Steel panels are supported by inflatable bags spanning the full panel length. Only a simple foundation is required, allowing construction atop existing foundations and application in dam heightening projects.

5. Assembled from interconnected reinforced steel plates and dam bags, the gate has unlimited overall length with no intermediate supporting piers. It preserves the clear width of river channels and cuts costs for hoisting equipment and auxiliary civil engineering works.
6. Clean compressed air serves as the actuation medium, eliminating water and ambient contamination as well as hydraulic oil leakage or delayed operation issues commonly found in hydraulic hoists.
7. No mechanical bearings or guide grooves are adopted, ruling out water seal blockage from sediment entering grooves and space occupation by hydraulic arms.
8. Steel sheets backed by air bags fully shield the bags against damage from driftwood, gravel, ice and other floating debris, granting a service life exceeding 15 years, longer than that of conventional rubber dams.
9. Continuous water level adjustment allows gradual acceleration of water flow, effectively avoiding cavitation, riverbed scouring and vortex formation. The optimized structural design eliminates vibration during gate operation.
10. Air bags are fabricated from food-grade materials to guarantee intact water quality.
