Basic Composition and Common Application Sites of Air-Shield Dams in China
Today we bring you a detailed introduction. New learners, keep reading!
1. Air Bag
Made of multi-layer NN66 or aramid framework material and special rubber with several authorized production patents. Working pressure ranges from 0.7 to 0.8MPa and the designed inflation pressure is 8 kilograms, with a safety factor 15 times that of rubber dams. Its outer layer is premium EPDM polymer with superior weather and ozone ageing resistance, featuring an anti-ageing lifespan of more than 50 years.
2. Water Retaining Shield Plate
Material: Stainless steel, carbon steel (polyurea-coated or hot-dip galvanized on surface)Specification: 5 meters per unit; adjacent units flexibly connected via high-strength composite rubber strips.Structure: Curved plates processed from steel sheets over 16mm thick, with reinforcing ribs welded on the upstream face.
Application of Domestic Air-Shield Dams for Water Diversion and Flood Diversion
1.Suitable for river flood diversion to realize automatic flow regulation in Jiangxi Province.
2.Automatically controls upstream water level during flood seasons to maintain a low-water level and flush away upstream deposited sediment by floodwater.
Application of Domestic Air-Shield Dams in Cold Regions
1.This type of gate has been successfully put into service in cold areas.
2.Supported by independent rubber airbags, the steel panels allow ice floes and floating debris to pass through.
Domestic Air-Shield Dams for Road and Garage Flood Protection
1.The gate system can be installed at entrances of garages and subways to block rainstorm flood inflow.
2.It can also be mounted on breaches of flood dykes and shut down promptly upon flood arrival.
