摘要

The piles (10) have a part (12) in ground (40) and a part above the ground. The part above the ground is formed of a sleeve and the part (12) has a connecting end opposite to the free end, where the connecting end is arranged inside the sleeve. The part above the ground has a rough outer surface and has a mixture of plastic and vegetal material. The part above the ground is connected to the part (12) along the end by extrusion with double die, where the die has a central die to extrude the part (12) and an outer die to extrude the part above the ground partially around the part (12).
