Abstract

L'invention concerne un canal Venturi (1) en matériau composite stratifié comprenant deux parois latérales (10, 11) définissant un rétrécissement localisé (101) de la section dudit canal, caractérisé en ce qu'il comprend, sur la face externe de chacune desdites parois latérales (10, 11), au moins un renfort (20, 21) s'étendant longitudinalement et en ce que chaque renfort (20, 21) comprend deux flancs (20a, 20b ; 21a, 21b) inclinés par rapport à la paroi latérale (10, 11), chacun desdits flancs présentant des orifices (200a, 200b) permettant l'écoulement du béton lors d'une étape de coulage de béton autour dudit canal.The invention relates to a Venturi channel (1) made of laminated composite material comprising two side walls (10, 11) defining a localized narrowing (101) of the section of said channel, characterized in that it comprises, on the outer face of each of said side walls (10, 11), at least one reinforcement (20, 21) extending longitudinally and in that each reinforcement (20, 21) comprises two flanks (20a, 20b; 21a, 21b) inclined with respect to the side wall (10, 11), each of said flanks having orifices (200a, 200b) allowing the flow of concrete during a step of pouring concrete around said channel.
