PROBLEM TO BE SOLVED: To make a quick and easy change between a " shallow hat-shaped steel sheet pile of JIS 10H or deep hat-shaped steel sheet pile of JIS 25H" and a "U-shaped steel sheet pile and/or H-shaped steel pile" without replacing a vibration generator and a chuck device is the attachment/detachment of them by improving a technology for gripping a pile by a chuck mounted to the vibration generator. SOLUTION: Flange connecting bodies 14A, 14B constituted by extracting portions corresponding to flanges of two kinds of hat-shaped steel sheet piles can be gripped by any one of a chuck for the hat-shaped steel sheet pile of JIS 10H and a chuck for the hat-shaped steel sheet pile of JIS 25H. A chuck 8 for the H-shaped steel can grip both the H-shaped steel pile and U-shaped steel sheet pile. COPYRIGHT: (C)2009,JPO&INPIT
