Abstract

PURPOSE: To drive and extract a pile under a proper condition corresponding to the nature of the ground by a method wherein a piston is moved up and down by means of a pulsation generator, and the vibration is transmitted to the pile, in a pile driver- extractor for the pile such as a steel sheet pile.
CONSTITUTION: Oil pressure generated by means of an oil pressure apparatus is applied to a pulsation generator 21 and a variable flow-rate regulating valve 22 from a change-over valve 20. The revolution of an oil pressure motor 23 is controlled by means of the variable flow-rate regulating valve 22, its revolution is transmitted to a rotor, and the speed of revolution of the rotor adjusts the number of pulsation. Pulsation generated is alternately discharged from the outlet ports 21a, 21b. Pulsation from the outlet ports 21a, 21b is introduced to the connecting ports 16, 17 of a cylinder 13 through a working change-over valve 24. A piston of the oil pressure machine 13 is moved up and down to generate vibration, and the vibration is delivered to the pile. The functioning of the oil pressure machine 13 is changed by the change-over of the working change-over valve 24, and the driving and extraction of the pile are changed over.
