Concrete foundation pile comprising an elongate body, a screwthread element extending helically over a considerable part of the length of the pile, an engaging surface for transferring a couple to the body is formed by the bounding surface of a cavity extending in mainly this part of the pile. The cavity has a substantially constant cross-section. The pile can consist of a number of pile sections lengthwise arranged with their end surfaces one against the other. The invention furthermore relates to a device for driving such a foundation pile into the ground, comprising a rod-shaped element capable of engaging in the cavity. This rod-shaped element can comprise a drilling point capable of protruding out of a foundation pile provided with a throughgoing cavity. |
