Rubber dams
An inflatable weir is a pernament structure consisting of a rubber-textile membrane (the body of the inflatable dam) fixed to a concrete bed using steel anchors and anchoring bolts. The inflatable weir is connected via a system of pipes to a control shaft that provides fully automatic operation of the dam structure via an electronic device.
The simple and environmentally friendly characteristics make it deal for small hydroelectric plants, irrigation systems, ground water treatment systems, recreational purposes and for reconstructing older, fixed or mobile weirs, and flood control.
Rubena inflatable bladders, which have been manufactured since 1963, feature the unique technology for membrane production (they are 8 up to 50 mm thick) and the top technical standard based on our own know-how.
Advantages of inflatable dams in comparison with other weir closure
- low acquisition and operating cost,
- no negative environmental impact,
- hundreds of successful installations,
- high resistance to vibrations during overflowing water, which can be increased with vulcanized baffles if required,
- complete installation and service maintenance globally,
- low maintenance lower structure and reconstruction of old fixed weirs or weirs with sluice or water gates,
- low maintenance and operation costs,
- waterfront pillars can be modified from the perpendicular to a tilt of 1:3, with the pillar axis not perpendicular to the longitudinal axis of the weir
- problem-free winter operation
- simple regulation of the top level with an accuracy of ± 2 cm even for flood flow rates up to the capacity
of the given dedicated opening, - more than 30 years lifetime
- practically the only alternative for horizontally or vertically curved overflow edges.
