To provide a coating corrosion prevention method of a steel pipe sheet pile, capable of eliminating the defect of conventional coating corrosion prevention for steel pipe sheet piles and achieving a better corrosion prevention effect at a lower cost.
In a coating corrosion prevention method of a steel pipe sheet pile, for performing corrosion prevention of a steel pipe part of a steel pipe sheet pile by a protective cover having a corrosion-proof layer inside thereof, the protective cover is halved and the protective covers are fixed and connected with each other by rivets. Preferably, stud bolts are fixed to a connection part connecting the steel pipe part of the steel pipe sheet pile perpendicularly to the normal line of the steel pipe sheet pile, a connection plate formed to be matched with the shape of the connection part and integrated with the corrosion-proof layer is fitted to the stud bolts, and a previously formed flange part is fitted to one end of the protective cover and fixed by nuts, thereby forming a continuous protective layer and corrosion-proof layer.
