Abstract
A method of erecting a pylon of a wind power installation is provided. The method includes providing a foundation and placing a plurality of height adjusting units on the foundation. The height adjusting units are made substantially from a plastic material. A load distribution ring is placed on the plurality of height adjusting units. The load distribution ring is straightened and leveled by adjustment of the height adjusting units. A gap between the foundation and the load distribution ring is filled with a grouting material. A pylon segment is placed on the load distribution ring after the grouting material has reached a predetermined strength. The height adjusting units are configured to jointly bear the weight of the load distribution ring, and are configured to yield under a selected load that is greater that a weight of the load distribution ring.
