Abstract

Dispositif de protection cathodique des chaînes d'ancrage. Dans un tel dispositif, la chaîne étant du type comportant au moins un maillon à étai, l'étai d'au moins un maillon est constitué, au moins pour une couche externe de matériau anodique soluble. Un tel dispositif permet d'assurer la continuité de la protection cathodique d'une chaîne d'ancrage pour un nombre d'années déterminé.
