PROBLEM TO BE SOLVED: To provide steel for an underground continuous wall, the underground continuous wall, and the construction method of the underground continuous wall which eliminate the need for temperature control after welding such as weld joining and complicated work such as bolt joining over the overall length in the longitudinal direction. SOLUTION: The steel for the underground continuous wall is constituted by a steel sheet pile and the steel having an H-shaped or T-shaped cross section. The steel sheet pile has a web part in the middle section in the width direction, and a coupling is provided on both ends of the steel sheet pile. The steel having the H-shaped or T-shaped cross section has a flange part at the ends of the web part. The web part of the steel sheet pile and one of the flange parts of the steel having the H-shaped cross section or the flange part of the steel having the T-shaped cross section overlap one another along the longitudinal direction. Then only either of both of the ends of the overlapping part in the longitudinal direction is restrained. COPYRIGHT: (C)2009,JPO&INPIT
