Abstract

Ce dispositif comporte un puits 3 réalisé dans le même matériau que la structure 2 à protéger et fixé sur celle-ci par soudage, dont une extrémité débouche dans le fond de la structure et met le puits en communication avec l'eau de mer et dont l'autre extrémité débouche au-dessus de la ligne de flottaison de l'ensemble, ce puits servant de logement à une anode 6 de protection cathodique liée électriquement au puits et par conséquent à la structure à protéger. Application à la protection de la partie immergée de coques de navires.
