Air - shield Dam
The air - shield dam, also known as the air - shield gate or pneumatic steel - shield rubber dam, is a new type of water - retaining structure. It combines the advantages of rubber dams and steel gates, integrating rigidity and flexibility. This structure was developed by the American company OHI in the 1990s. Its structure mainly consists of shield plates, inflatable air - bags, and a control system. The inflatable air - bags are used to support the shield plates to block water. When the air - bags exhaust air, the dam collapses, and the air - bags lie under the shield plates, which can prevent the damage to the dam bags caused by sand, stones, and ice in the river. The medium filled in the air - bags is gas, so the dam can collapse rapidly. All components are pre - fabricated, resulting in a short installation period. The shield plates and air - bags are modular, which is convenient for repair.
