Main Application Fields of Air Shield Dams in Municipal & Hydraulic Engineering
Air shield dams are multi-functional water control facilities with wide adaptability. They are used across multiple scenarios for water resource management.
Urban river ecological restoration is the most typical application. Many city rivers suffer from low water level and exposed riverbed during dry seasons. Air shield dams store water to raise river level, form continuous water surface, improve water self-purification and beautify waterfront landscape. In flood seasons, the dam flattens quickly to release flood and prevent urban waterlogging.
Agricultural irrigation is another key field. In farmland canals and irrigation rivers, air shield dams adjust stored water volume according to crop demands. It balances water supply between dry and wet seasons and guarantees stable irrigation for farmlands.
For flood control and emergency drainage, air shield dams help regulate flood peaks. During heavy rains, rapid deflation reduces river water pressure and protects villages, farmlands and cities from inundation.
Besides, air shield dams are also used for tailwater regulation of reservoirs, water isolation in tidal zones, scenic area water management and small hydropower flow control.
