1. 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.
