Abstract
PURPOSE: To enable smooth and sure press-in of a pile by pressing in the pile while rotating the same in the normal and reverse directions or in one direction and thereby reducing the frictional force of the pile with the ground.
CONSTITUTION: A cap tube 7 holding the upper end part of the pile P is fitted to the lower end part of a main body 1. In the circumference of the cap tube 7 are opened a plurality of slits 7a, into which taper pieces 8 are inserted. On the outer side surface of the piece 8 is formed a slant 8a, with which the inside taper surface 9a of a taper ring 9 contacts, and when the ring 9 moves downward, the piece 8 moves inward to tighten the pile P firmly and hold the same. Between a base plate 5 and a cylinder plate 10 a hydraulic cylinder 13 is installed intermediately and rotates the pile P repeatedly in the normal and reverse directions by the motion of a piston rod 13a through the intermediary of the main body 1, the cap tube 7, the pieces 8, etc.
