<p>The present invention relates to an arrangement for increasing the load carrying capacity of a preferably in the ground installed pile (3) or similar including at least one with the pile (3) mainly concentrical tube (5) attached to the pile (3) with at least one between the pile (3) and the tube (5) extending rib (6), the pile (3) extending throughout the tube (5) and at least one cell being created. The arrangement is characterized in that the rib (6) extends over the whole length of the tube (5) and the height of the preferably vertically installed upwards and downwards open cell is at least as large as the diameter or the largest diagonal of every area in the cell in a plane perpendicular to the mainly vertical direction of extension of the cell at the same time as the tube (5) has a smaller diameter or diagonal in one end than in the other.</p> |
