Foundation column intended for pressing into ground

摘要

The column shaft (2) is a metal pipe, and the widened formation (3) has a metal cover (4) limiting its outer periphery. The cover all round is located at a distance from the metal pipe and the ring-shaped space (5) between the metal cover and the metal pipe is filled with concrete. The metal cover at the lower end of the foundation column extends past the metal pipe. The concrete at the lower end of the foundation column forms a surface (6) extending between the metal cover and the metal pipe with the shape of a truncated cone.
