Abstract

L'invention concerne un traitement contre la corrosion d'une structure portante creuse (MP), métallique et immergée dans de l'eau, dans lequel on applique deux ouvertures aménagées dans la structure, avec: - une première ouverture (T1), pour une entrée d'eau dans la structure, et - une deuxième ouverture (T2), pour une évacuation d'eau depuis la structure, permettant d'évacuer une acidité d'eau dans la structure, issue par exemple d'un traitement galvanique de protection contre la corrosion.
