ABSTRACT:
A method and apparatus for driving a hollow pile into the ground. By using a hollow rod having a short auger fixedly secured to a leading end portion thereof, excavated earth and sand are lifted to and around the upper portion of the auger where compressed air is spouted from nozzle orifices formed in the hollow rod thereby lifting the excavated earth and sand through the hollow pile and consequently discharging the same from the hollow pile. As earth and sand are discharged from the hollow pile, the pile is sunk or driven into the ground.
