A general-purpose steel-sheet-pile press-in and extraction machine is capable of handling a steel sheet pile having an arbitrary joint pitch and both a U-steel sheet pile and a Z-steel sheet pile. This steel-sheet pile press-in and extraction machine includes: a plurality of clamping devices 3 each of which clamps an already-disposed steel sheet pile by allowing a clamp cylinder to stretch a movable clamp claw (fig.3, 13) toward a fixed clamp claw (fig.3, 12), with a clamp claw (fig.3, 25) made up of the fixed clamp claw 12 and the movable clamp claw 13 straddling an upper-end part of the steel sheet pile; a chucking machine 10 which chucks the steel sheet pile to be pressed in and extracted by allowing a chuck cylinder (fig.14, 54) to stretch a movable chuck claw (fig.14, 53) toward a fixed chuck claw (fig.14, 52), with the steel sheet pile inserted through between the fixed chuck claw 52 and the movable chuck claw 53; and a press-in and extraction cylinder 9 for pressing in and extracting the chucked steel sheet pile, in which the position of the clamp claw 25 of each clamping device 3 is adjustable both along and perpendicular to the already disposed steel sheet piles. |
