Pneumatic Shield Type River Dam

Shield type dam, also named pneumatic shield type rubber dam, pneumatic spillway gate, shield type steel river dam, is a new kind of water dam integrating the advantages of traditional steel dam and rubber dam. It consists of civil works, embedded components, shield plates, air bladders, pneumatic charging and discharging system. Steel shield plates provide front stop water; rubber air bladders provide support for shield plate; a row of basic anchor bolt and soft connection construct the whole structure of dam; a set of pneumatic charging and discharging system provides operating power to achieve rise dam and lower dam. Shield plates and air bladders are connected with the base by anchor bolts and high strength rubber compound belts. If the gate is fully open, shield plates all lying on the riverbed, not affect navigation. If the gate is fully closed, overflow can form various artificially designed overflow landscape. It is easy to install and repair, has short construction time and long service life. It is widely applied to many fields such as water conservancy, hydroelectricity, water transportation, moisture proof and beautify the environment, etc.
