PROBLEM TO BE SOLVED: To provide an installation steel material which is an installation steel material for cut-off wall formation and can securely inject a desired amount of cut-off material into a gap part formed when the installation steel material is extracted from the ground.;SOLUTION: An installation steel material 1 includes: a hat type steel sheet pile 10; a plate-like outflow prevention part 11 which projects along a thickness of the hat type steel sheet pile 10 to one width-directional end side of the hat type steel sheet pile 10 and is extended and fixed along a length of the hat type steel sheet pile 10; a tip reinforcement part 13 which is formed projecting along the thickness of the hat type steel sheet pile 10 on a lower end side of the hat type steel sheet pile 10 over substantially the overall width-directional length; and a cut-off material injection pipe 12 which is extended and fixed along the length of the hat type steel sheet pile 10, and has its lower end side penetrating the tip reinforcement part 13. The tip reinforcement part 13 has its one end part abutting on the outflow prevention part 11, and is formed along the hat type steel sheet pile 10 from the outflow prevention part 11 to a joint part 10d2 on the other end side of the hat type steel sheet pile 10.;COPYRIGHT: (C)2014,JPO&INPIT
