Abstract
A fusegate for a hydraulic structure includes a trough with walls for attaching the normal barrage at a predetermined height, a pressure chamber provided between a base of the fusegate and the upper surface of the spillway, a means for pressurising the chamber according to a maximum predefined height of a water level upstream of the fusegate, the fusegate further comprising systems for breaking ice which are attached to the gate.
Claims7
A fusegate for a hydraulic structure having
- a trough comprising walls making it possible to fix the normal impoundment at a predetermined height,
- a pressurizing chamber provided between a base of the fusegate and an upper surface of a spillway on which the fusegate is positioned,
- means for pressurizing the pressurizing chamber according to a predefined maximum height of a water level upstream of the fusegate, wherein the fusegate also has systems for breaking ice that are attached to the fusegate
- wherein the systems for breaking ice have at least one elongate element, a free end of which is positioned at a height corresponding to the possible presence of a layer of ice on the water impoundment, lower than the impoundment height, and
- wherein the systems for breaking ice have at least one elongate element in the shape of an “L”, one end of which is attached to the trough.
