Gas shield dam

Air shield dam, air shield gate, also known as pneumatic steel shield rubber dam, is a new type of water retaining structure. It has both the advantages of rubber dam and steel gate, and is both rigid and flexible. Its structure is mainly composed of shielding plate, inflatable air bag and control system. The inflatable air bag is used to support the guard plate to retain water. After the air bag is exhausted, the embankment collapses, and the air bag is located under the guard plate. Can avoid the damage of river sand and ice to the dam airbag. The bladders are filled with gas, and the dam collapses quickly: all parts are prefabricated. Short installation cycles; shields and airbags are modular for easy repair.

Air shield dam is a new hydraulic structure combining the length of rubber dam and steel plate dam. The air shield dam absorbs the essence of the traditional movable dam type, and abandons the shortcomings of the traditional movable dam type. The structure is simple, the construction and installation period is short; the flood control ability is outstanding, the operation is safe and reliable; the height of the water passing and the operation state are continuously controllable; Simple management; long service life. High comprehensive benefits; strong earthquake resistance, strong adaptability to the foundation; good landscape effects, etc.

Characteristics of gas shield dams

1. Precise and automatic control of water level even in the absence of electricity (especially suitable for hydropower generation);

2. Modular design can simplify the installation process. Reduce post-maintenance;

3. Simple structure, low cost, no water resistance. watertight;

4. The ultra-thin shape can be well injected with water. Pass ice and debris etc.

5. The guard plate can protect the rubber airbag from floating objects and sundries;

6. The present invention can realize automatic control, low power consumption and cost saving;

7. The control system uses air as the inflation medium, so there is no oil leakage problem. Will not cause water and surrounding environment pollution.
