摘要
PROBLEM TO BE SOLVED: To provide a method and a structure for the anticorrosive corrosion-lining of a steel-pipe pile corrosion-proof capable of readily preventing corrosion of the corrosion-resistant lining of a steel-pipe pile without adversely affecting pile-head concrete placed at the upper end of the steel-pipe pile.;SOLUTION: A corrosion-resistant layer 8 is provided between the pile-head concrete 2 at the upper end of the steel-pipe pile 1 and the corrosion-resistant lining 3 to isolate them from each other. The surface of the corrosion-resistant lining 3 covering the surface of the steel-pipe pile 1 is covered with a water-absorbing layer 4 and a drying-prevention cover 5 in that order. The corrosion-resistant lining 3 is always kept immersed in seawater absorbed and retained by the water-absorbing layer 4 to shut off the supply of oxygen from outside to reinforcement 3a inside the corrosion-resistant lining 3 and also to make the reinforcement 3a conduct a corrosion-resistant current coming via the seawater retained in the water-absorbing layer 4 and from a galvanic anode 7 provided in the undersea portion of the steel-pipe pile 1.;COPYRIGHT: (C)2008,JPO&INPIT
