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 female 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 steel-pipe sheet pile is a joined-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-section.
