In Hydroconstruct’s water-filled version, the regulating shaft system comprises a shaft structure with individual chambers equipped with corresponding hydraulic regulating and control devices such as flaps and gates. The regulating chamber is connected to the interior of the rubber dam via a pipe system incorporated in the weir foundation structure. Control is via a headwater probe. The weatherproof control cabinet with the electrical controls and regulating equipment is located directly at the weir or very close by.
In the standard Hydroconstruct design, all steel components (clamping system and pipes in the regulating shafts) are hot-dip galvanized, the pipes set in concrete are made of PVC plastic, and the anchor bolts are made of stainless steel.
The water-filled rubber dam system is particularly notable for delivering unrestricted regulation of the dam level. When the outflow increases, the dam height lowers continuously. When the inflow decreases again, the height is continuously raised again by the filling pump.
In winter operation, when the rubber dam is stationary and not overflowing, the fill-water can be protected against ice formation by pumping through a small amount river water with a temperature greater than 1°C.
