Abstract
PURPOSE: To prevent buckling of a pile and maintain the strength of the driven pile, by driving a pile with smaller diameter first and a larger pile next when the piles are driven into the underground by screw revolving method.
CONSTITUTION: The pile B and the pile C are prepared. The pile B consists of a shaft 20 with smaller diameter equipped with screws 21 at its top end. The pile C consists of a guide 32, a spacer 33 and the shaft 30 that has a larger diameter than the pile B and is equipped with screws 31 at its top end. The pile C is positioned concentrically with the pile B. First the smaller pile B is driven deep enough with smaller torque into the underground by revolving. Then the pile C is driven so that the shaft 20 of the pile B penetrates through the inside of the pile C and each pile matches. Then the pile C is revolved independently so that it protect the smaller pile which is apt to buckling. Thus a stronger underground pile can be obtained with a smaller torque.
