CORROSION PROTECTING CONSTRUCTION STRUCTURE AND CORROSION PROTECTING CONSTRUCTION METHOD

摘要

To provide a corrosion protecting construction method which has high salt-shielding property for a long period and can achieve long term durability by shielding ultraviolet ray.SOLUTION: A corrosion protecting construction method forms a corrosion protecting layer containing an antirust layer, a plastic layer and a protection layer on a side face of a supporting portion in a marine structure including an upper concrete structure and the supporting portion which supports the upper concrete structure from a lower face and protects corrosion. The corrosion protecting construction method comprises: a corrosion protecting layer forming step of forming the corrosion protecting layer on the side face of the supporting portion so that a gap is formed between an upper face of an outwardly protruding protrusion existing at an upper end of the protection layer and an upper face of the corrosion protecting layer, and a lower face of the upper concrete structure; and a press-fitting step of press-fitting a seal material into the gap and making the seal material reach the upper face of the protrusion.SELECTED DRAWING: Figure 1
