Abstract

La présente invention concerne un système de contrôle de marées à commande hydraulique comprenant une plaque étanche (2) normalement disposée dans le sous-sol et entraînée à la surface du sol lors du contrôle des marées, un support sous forme de bâti (50) prévu à la surface conjointement avec la plaque étanche (2), et un dispositif de commande pour entraîner la plaque étanche (2) vers la surface du sol depuis le sous-sol. Le dispositif de commande comporte une unité piston/cylindre hydraulique (40) fonctionnant à l'eau urbaine, l'eau d'un réservoir d'eau, l'eau d'un réservoir d'eau de pluie, ou analogue. La plaque étanche (2) est entraînée sans contact en élévation jusqu'à une position déterminée et les parties se trouvant sur ses bords (3, 3, 4) viennent en butée contre le support sous forme de bâti (50) lorsque la position déterminée est atteinte. Le système peut être opéré même en cas de panne d'électricité sans indûment gâcher la vue de bord de mer et peut être commandé à distance.
