T002 Aill Filled Filling Pneumatic Inflatable Rubber Dam/Weir for River

Rubber dams and their applications

Rubber dams are weir systems in which an elongated rubber body is firmly connected to the foundation of the weir system. The rubber body can be filled with water or air, depending on the design. The height and thus the overflow of the weir can be determined by filling and draining the weir. Water-filled rubber dams are usually filled with river water, controlled by the hydrostatic pressure of the water in the regulating shaft.

Theoretically, independent regulation by the pressure of the overflowing water is also possible; the rubber dam lowers independently by reducing the overpressure via an overflow threshold. This is a feature that is otherwise only possible with electronic control.



 

Our Advantages

 

The advantages of rubber dams over conventional weir systemsLow acquisition cost
The rubber dam is a safe and user-friendly operation
UV-treated high-quality EPDM withstands icing and harsh climates.
The resistance of these dams to environmental factors such as water, pollutants, saline, and alkaline waters, toxic residues, sewage, and acids
Low maintenance and service requirements and low operation cost
The life expectancy of 30 to 40 years based on various international applications
No adverse impacts on the environment because of its operation without any oils and lubricants
Led Lighting
High resistance against vibrations in overflowing water is increased if needed by non-vulcanized baffles.
