Title: Pile made from rust-proof composite steel pipe
Inventor: MIURA NOBUTAKA
IPC: C09D5/08
Filed: 1982-06-14
Abstract: PURPOSE:To manufacture a pile from a rust-proof composite steel pipe capable of inhibiting rusting even when the coated layer is damaged, by coating it with a coating layer consisting of a compd. having polyoxyphenyl groups as the basic structure and a binder. CONSTITUTION:A steel pipe pile or steel-clad concrete pile (SC pile) is coated with a coating layer consisting of a compd. having polyoxyphenyl groups as the basic structure (e.g. tannin, tannic acid or dihydroxy- or trihydroxybenzene) and a binder (e.g. a combination of hydraulic material such as cement and a resin emulsion). The compd. having polyoxyphenyl groups forms a stable, water-impermeable rust compd. with iron on the surface of the steel pipe. When the coated layer is damaged during piling, the compd. not in contact with iron bleeds and forms a protective film to inhibit rusting. The added binder improves the strength of the coated layer per se and adhesion between the coated layer and the steel pipe and increases the wear resistance during piling.
