FUSEGATE FOR A HYDRAULIC CONSTRUCTION, IN PARTICULAR A DAM
The invention relates to a fusegate (1, 1A-1E) for a hydraulic construction, characterised in that said fusegate includes: a transverse wall (12) that is produced in a substantially sealed manner with a base (11), and means for limiting the impact of the gate on the structure (3, 18) of the hydraulic construction when said gate is retracted.
The invention relates to a fusible shutter for a hydraulic construction such as a weir, a spillway on a dam or a safety embankment, that comprises a solid member (19) provided on the crest of the construction and maintained thereon by gravity in order to define a watertight or substantially watertight wall, installed on said hydraulic construction and capable of withdrawal so as to let the water flow freely when the level of the reservoir or river reaches a predetermined level, wherein a chamber (2) is formed at the base of the solid member (1) between the latter and the surface bearing same, and pressurising means are used for filling the chamber (2) with water in order to generate under the solid member an upward force when the water of the reservoir or the river reaches the predetermined level. According to the invention, the pressurising means include a water intake level with a supply structure (3) including two compartments (3a, 3b) defined by an inner vertical wall (4), wherein the two compartments (3a, 3b) communicate via at least one passage (5) in the upper portion of the supply structure (3), one of the compartments (3a) having one or more openings in the lower portion thereof for the intake of water from the reservoir or the river into the supply structure (3), while the other compartment (3b) communicates with the chamber (2) under the solid member (1). The invention can be used in a hydraulic construction such as a weir, a spillway on a dam or a safety embankment.
The invention relates to a fusegate for a hydraulic construction such as a river sill or a spillway on a weir or on a protective dyke, comprising a massive element (1) arranged on the crest of the construction and held thereon by gravity so as to form a watertight or substantially watertight wall, said element being installed on said hydraulic construction and being able to move aside in order to allow water to flow through without obstruction when the level of the reservoir or of the waterway reaches a predefined level, and a chamber (2) being formed at the base of the massive element (1) between the latter and the surface which supports it, pressurizing means enabling the chamber (2) to be filled with water so as to generate, below the massive element, an upwardly directed thrust when the water of the reservoir or of the waterway reaches the predefined level. The invention is defined by the fact that these pressurizing means consist of a water intake at a supply structure (3) provided with two compartments (3a, 3b) defined by an inner vertical wall (4), the two compartments (3a, 3b) being in communication with one another via at least one passage (5) formed in the upper part of the supply structure (3), one of the compartments (3a) having one or more openings in its lower part whereby water from the reservoir or the waterway can enter the supply structure (3), whereas the other compartment (3b) is in communication with the chamber (2) below the massive element (1). Applications in hydraulic constructions such as a river sill or a spillway on a weir or on a protective dyke.
