A steel-pipe sheet pile including a steel pipe and joints for coupling the steel pipe to another steel pipe and multiple steel pipes arranged in a building direction of a steel-pipe sheet pile wall, wherein the joints include a male joint and a sale joint each made of an H-shaped steel-beam coupled at flange edges to the steel pipe, and wherein the male joint is slightly smaller in size relative to the female joint so that the 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. The inside surfaces of the flanges of the female joint and the outside surfaces of the flanges of the male joint are provided with projections, respectively. The steel-pipe sheet pile is a jointed steel-pipe sheet pile including multiple steel pipes integrally coupled to one another via H-shaped steel-beams as 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 a building direction of a steel-pipe sheet pile wall.
