ABSTRACT STEEL MATERIAL FOR UNDERGROUND CONTINUOUS WALL, MET D FOR PRODUCING STEEL MATERIAL FOR UNDERGROUND CONTINUO S WALL, UNDERGROUND CONTINUOUS WALL, AND METHOD FOR CO TRUCTINGUNDERGROUND CONTINUOUS WALL,A steel material for an underground continuous wall ( in one embodiment is z ) equipped with a hat type steel sheet pile (2) and an H-s ction steel (6), wherein a dimension (L2) of the H-section steel in the length direct' n is shorter than a dimension (LI) of the hat type steel sheet pile in the length dire ion, an overall length of the H-section steel is arranged with the dimension of the h type steel sheet pile, and a rear end (20) of the H-section steel is located closer to a rward end side than a rear end (18) of the hat type steel sheet pile. In a steel mate ' 1 for an underground continuous wall in another embodiment, a position of the rear nd of the hat type steel sheet pile coincides with a position of the rear end of the H-s ction steel in the length direction, a forward end (21) of the H-section steel is located oser to the rear end side than the forward end (19) of the hat type steel sheet pile, and separation length (B) between the forward end of the hat type steel sheet pile and th orward end of the H-section steel is not more than 35% of the overall length of the steel material for the underground continuous wall in the length direction. In the ethod for producing the steel material for an underground continuous wall, the type steel sheet pile and the H-section steel are secured to each other by welding. a underground continuous wall is constructed using a plurality of steel materials r an underground continuous wall. The method for constructing the underground ontinuous wall uses a plurality of steel materials for an underground continuou all. ABSTRACTSTEEL MATERIAL FOR UNDERGROUND CONTINUOUS WALL, METHOD FOR PRODUCING STEEL MATERIAL FOR UNDERGROUND CONTINUOUS WALL, UNDERGROUND CONTINUOUS WALL, AND METHOD FOR CONSTRUCTING UNDERGROUND CONTINUOUS WALLA steel material for an underground continuous wall equipped with a hat type steel sheet pile having a hat-shaped cross-section, and an H-beam having an H-shaped cross-section, wherein: the hat type steel sheet pile includes a web, a pair of flanges, and a pair of arm sections; the H-beam includes a pair of flange sections and a web section; an outer surface of the H-beam is secured to an outer surface of the web; the length of the H-beam is shorter than that of the hat type steel sheet pile, and an overall length of the H-beam is arranged within the length of the hat type steel sheet pile; and a rear end of the H-beam is located closer to a forward end side than a rear end of the hat type steel sheet pile.
