摘要
The present invention relates to a high water spillway (5) for barrages and similar structures, comprising a spill threshold (6), the crest of which is located at a first predetermined level (RN) lower than a second predetermined level (RM) corresponding to a maximum level or to the highest water level (PHE) for which the barrage (1) is designed, the difference between said first and second levels (RN and RM) corresponding to a maximum predetermined flow of an exceptional high water, and a fusegate (10) plugging the spillway (5), said gate (10) comprising at least one rigid and solid gate element (11), which is placed on the crest (8) and is held in place thereon by gravity, said gate element being imbalanced when the water reaches a third predetermined level (N) higher than the top of the gate element (11), but at most equal to the second predetermined level (RM). According to the invention, said spillway further comprises an aeration system that comprises at least one duct (20) capable of routing air towards the bottom of the jet discharged by the crest of said gate (11).
