Abstract
A tool for making holes in the ground comprises a ram tip and coupling for connecting to a drive device, such as a hydraulically or pneumatically actuated pile driving machine, or a vibrating pile driving machine. A method for making tubular foundations in the ground comprises coupling a ram tip to a drive device, selecting a location for making a hole, placing the ram tip thereat, setting the drive device into operation to drive the ram tip into the ground to form a hole, removing the ram tip out of the hole, partially filling the hole with concrete, re-inserting the ram tip into the hole before the concrete sets, setting the drive device into operation and then removing the ram tip, thereby obtaining a tubular foundation.
