Product Description

T035 India Used Inflatable Rubber Dam USA Flexible Rubber Weir for River Water

Rubber dam is a permanent rubber bladder anchored in concrete foundation by anchor plates and anchor bolts. It is made of high strength fabric and synthetic rubber. The rubber dam filled with water or air could raise the water level in dry season and release floodwater from river course in rainy season. A layer of stainless steel mesh or ceramic chips can be embedded in the top surface rubber layer to reduce or prevent vandal damage. 



Main Advantages of Rubber Dams

• 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

Available Sizes:  

Height can be designed with a range of 1-8 meters.
Length can be 1000 meters, even longer.
