Shield dam:

You can find more information on our web, so please take a look.

Is a new type of gate which is combined with the advantages of the traditional steel gate and rubber dam. The shield is composed of shield plate, buried part, air bag and pneumatic system. The shield plate is a row of reinforced steel plate, the air bag is supported on the lower surface of the steel plate, and the air bag is used to control the shield plate and the water, and the angle of the shield plate can be precisely controlled. Full open gate, a shield plate all lying in the river, does not affect the landscape of navigation. The gate is fully closed, the gate can be formed in a variety of artificial landscape design of overflow.

Air shield dam is a new type of water conservancy building that combines the advantages of rubber dam and steel plate dam. This product absorbs the advantages of traditional activity dams and discards the shortcomings of traditional activity dams. It has a simple structure and a short construction and installation cycle. So what are the advantages of gas shield dams?

1. The pneumatic shield gate system overcomes the weakness of poor ecological and environmental protection functions of steel gates, rubber dams, and hydraulic self-control flap gates. The air bag of the gas shield dam system is made of food grade materials, driven by compressed clean air, without any mechanical oil, and will not cause water and environmental pollution. It has good environmental protection functions. The pneumatic shield shaped gate system facilitates the installation of fish channels, completely collapsing at the bottom of the river without any water level difference, and does not affect the up and down passage of aquatic organisms. It can maintain the ecological continuity of the river and effectively protect the ecological environment.

   Hengyang supply professional and honest service.

2. The pneumatic shield gate system has a wide range of applications and can be applied to gate and dam projects of various river widths, such as river renovation projects, hydropower projects, water diversion projects, agricultural irrigation projects, drought and drainage projects, coastal defense construction projects, dam elevation projects, wetland and groundwater cultivation projects, etc. When the gate overflows, it can also create an artificial scene that integrates with the surrounding environment, protecting the ecology and beautifying the environment, and can be used for urban landscape engineering. Especially suitable for gate and dam projects with large spans, low water heads, innovative planning requirements, and compact placement.

3. The shield shaped steel gate structure supported by the airbag can safely protect the airbag itself and prevent damage from floating wood, mud, ice, and other debris. The theoretical service life of the pneumatic shield shaped gate system can reach more than 30 years.

4. High safety function. The shield shaped gate can completely collapse at the bottom of the riverbed without affecting the flood discharge of the river. It can use both manual and active methods to control the water level, especially for power outages caused by flooding. It can still use manual control to urgently discharge air from the air bag to achieve safe flood discharge. After the flood discharge, even if sludge and other debris accumulate on the gate, it still does not affect its normal operation.
