Abstract

L'invention concerne un dispositif de dragage d'un chenal, constitué d'un navire avec au moins une hélice munie d'un carénage, et avec lequel on remet en suspension les sédiments meubles en dirigeant le jet de l'hélice sur le fond du chenal suivant un angle réglable Ce dispositif est remarquable par le fait que le navire comporte au moins un déflecteur orientable associé au carénage. Suivant l'invention, on peut également ballaster un navire, dont l'arbre porte-hélice est incliné sur l'horizontale, pour diriger le jet de l'hélice de ce navire suivant un angle réglable.
