Claim:
A steel-pipe sheet pile including a steel pipe and joints for coupling the steel pipe to another steel pipe in multiple steel pipes arranged in a building direction of a steel-pipe sheet pile wall, wherein said joints include a male joint and a female joint each made of an H-shaped steel-beam coupled at flange edges to a peripheral surface of said steel pipe, and wherein said male joint is slightly small-sized relative to said female joint so that said male joint can be fitted in a space defined by flange inside surfaces and web surface of a female joint of a neighboring steel-pipe sheet pile; and said steel-pipe sheet pile is a joined-steel-pipe sheet pile in which multiple steel pipes are integrally coupled to one another via tying members of H-shaped transverse cross-sections, respectively, such that each tying member has flange edges coupled to peripheral surfaces of the associated steel pipes to be plurally arranged in said building direction of a steel-pipe sheet pile wall.
