In a corrosion-protective coating structure for the base steel of a marine steel structure, the top part of which is buried in reinforced concrete and the lower part of which is exposed in the air and/or water, the reinforced concrete of the base steel is used. Including the boundary between the buried part and the part exposed in the air and/or water, and from this boundary in the reinforced concrete and the upper part exposed in the air and/or water, the covering material is impermeable and electrically insulating. A cladding consisting of a corrosion-proofing material and a protective material on the outside thereof, in which all or part of the base steel is coated and partially overlaps the lower end of the part of the cladding exposed to air and/or water. An anti-corrosion coating structure for marine steel structures characterized by being coated with. 2. The anticorrosive coating structure for marine steel structures according to claim 1, wherein the water-impermeable and electrically insulating coating material is a plastic tape or sheet having an adhesive layer. 3. The anticorrosion coating structure for marine steel structures according to claim 1, wherein the water-impermeable and electrically insulating coating material is a heat-shrinkable tube. 4. The anti-corrosion coating structure for a marine steel structure according to claim 1, wherein the water-impermeable and electrically insulating coating material is a petrolatum-based anti-corrosion tape and a plastic tape or sheet coated on the outside thereof, or a fiber-reinforced plastic sheet. 5. The anti-corrosion coating structure for marine steel structures according to claim 1, wherein the anti-corrosion material is a petrolatum-based anti-corrosion tape or a petrolatum-based anti-corrosion sheet. 6. The anti-corrosion coating structure for a marine steel structure according to claim 1, wherein the anti-corrosion material is an epoxy resin or a resin mortar. 7. The anti-corrosion coating structure for a marine steel structure according to claim 1, wherein the anti-corrosion material is cement mortar or concrete. 8. The anticorrosion coating structure for marine steel structures according to claim 1, wherein the protective material is plastic or fiber reinforced plastic. 9. The anti-corrosion coating structure for a marine steel structure according to claim 1, wherein the protective material is a corrosion-resistant metal. 10. The anticorrosion coating structure for a marine steel structure according to claim 1, wherein the protective material is a composite material made of plastic or fiber-reinforced plastic with a soft foamed plastic sheet adhered to the inside.
