Product Description
Production Description
Rubber dams are a modern and innovative water management facility. They are composed of three main components: foundation construction, dam bags, and control and monitoring systems. Rubber dams are extremely flexible and can be remotely controlled through the control and monitoring system to complete the filling or inflation of the dam in just a few minutes. When it is necessary to lower the weater lvel, the rubber dam can also be easily controlled to drain or vent with just one click. They are faster to construct, less expensive, and more environmentally friendly.
Advantage
Flexible weir structure, allowing discharge of sediments, debris and ice
Fully automatic reservoir level control
Self-acting flood release; the automatic bucket drive lowers the weir without the need for external energy to power mechanical valve drives
Ideal for creating reservoirs in wide rivers; single spans of up to 100 m are feasible
Renovation and reconstruction of existiing weir structures, regardless of shape and geometric configuration, factory made as a single unit. On site this ready-made membrane just has to be secured in place by the clamping system
Absence of mechanical components eliminates corrosion risk
No lubricants needed - protects the environment
Low maintenance costs and low operating costs due to minimal energy requirements
More than 100 examples built since 1991
