Abstract:
In a configuration of a method for preventing progression of corrosion in a steel pipe structure according to the present invention, two or more types of liquids 150 are injected, while being mixed, into a steel pipe that constitutes the steel pipe structure, from an opening at one of both ends of the steel pipe, and the inside of the steel pipe is filled with resin foam product (foam product 152) by foam expansion and hardening of the two or more types of liquids.
