Abstract
(EN)
The invention concerns a device for triggering the destruction of a selected part (1, 11) of a hydraulic structure, such as a levee, dike or backfilled dam, the selected part comprising erodable materials such that it can be destroyed by hydraulic erosion. The device comprises at least one solid section (5) which is disposed at the top of the selected part (1, 11) of the structure and is held there by gravity. The size and weight of the solid section (5) are such that it can be expelled by water when the water reaches a predetermined level (N). The vertical dimension of the solid section measured below this predetermined level (N) is such that the outflow released when the solid component has been expelled is of a depth (z) which ensures that the selected part (1, 11) of the hydraulic structure is destroyed reliably and rapidly.

Ce dispositif pour déclencher la destruction d'une partie choisie (1, 11) d'un ouvrage hydraulique tel qu'une levée, une digue ou un barrage en remblai, construite en matériaux érodables tels qu'elle soit destructible par érosion hydraulique, est constitué par au moins un élément massif (5) qui est disposé sur la crête de la partie choisie (1, 11) de l'ouvrage et qui y est maintenu par gravité, l'élément massif (5) étant dimensionné en taille et en poids de manière à être chassé par l'eau lorsqu'elle atteint un niveau prédéfini (N), la dimension verticale de l'élément massif mesurée au-dessous dudit niveau prédéfini (N) étant choisie de telle sorte que la nappe déversante qui est libérée après que l'élément massif a été chassé ait une épaisseur (z) propre à provoquer une destruction sûre et rapide de la partie choisie (1, 11) de l'ouvrage hydraulique.
