(FR) OUVRAGE ET PROCEDE DE FRANCHISSEMENT DE DENIVELLATION, ET CANAL DE NAVIGATION
Abstract: front page image
(EN)The invention concerns a structure for crossing a head drop on a waterway, comprising a succession of at least three substantially horizontal head races (41, 42, 43), separated by gates (31) mobile between an open position and a closed position. The invention also concerns a method for crossing a head drop, which consists in successively controlling the structure gates (31) so as to enable the water in two adjacent head races to be at the same level. Finally the invention concerns a navigation canal with vertical walls comprising a structure for head race crossing.
(FR)L'invention est relative à un ouvrage de franchissement de dénivellation sur une voie d'eau, comportant une succession d'au moins trois biefs sensiblement horizontaux (41, 42, 43), séparés par des portes mobiles (31), entre une position ouverte et une position fermée. L'invention concerne également un procédé pour le franchissement d'une dénivellation, consistant à commander successivement les portes de l'ouvrage (31), de façon à permettre aux niveaux de deux biefs contigus de s'égaliser. L'invention est enfin relative à un canal de navigation à parois verticales comportant un ouvrage de franchissement de dénivellation selon l'invention.
