Protection And Repairs Of Steel Sheet Piles In Tidal Zone
Corrosion damage to steel sheet pile wharves is a major item of maintenance activities in the Mediterranean and Red Sea ports of Israel. During mid-90s, the problem of underwater corrosion was substantially mitigated by installation of cathodic protection. However, recent inspections indicated the need to protect sheet piles in the tidal zone as well. The paper describes the types of corrosion damage above MHW, and the methods of repairs and corrosion protection in this zone that are applied in contemporary international practice. The methods of tidal zone protection that were used in the Israeli ports included epoxy coating in caissons, jacketing with steel fiber concrete and cast-in-place capping beam extensions using high - plasticity polymer fiber reinforced concrete. The analysis of these methods showed that the most important factor is the effect of applied repair technology on wharf operations. The operational downtime and the durability assessment indicated that the polymer fiber concrete extension is a preferred alternative. The main message of the paper is that repairs of sheet piles in the tidal zone should be designed as an integral component of a larger system of corrosion protection of bulkheads. The guidelines on how to achieve this goal are provided.
