Abstract
A method of erecting a pylon, in particular a pylon of a wind power installation, which has a foundation with segment anchors, wherein connecting elements project beyond the top side of the foundation by a predetermined amount. A ring is leveled, aligned and fixed at the top side of the foundation. A gap produced by leveling, aligning and fixing of the ring is underlaid with a grouting material. The grouting material is set and a lower pylon segment is placed on the leveled, aligned and fixed ring and connected thereto.
Claims10
A method of erecting a pylon of a wind power installation, the method comprising:
- forming a foundation that includes a plurality of segment anchors, the plurality of segment anchors including pairs of connecting elements having first and second ends, the first ends of the pairs of connecting elements coupled to the segment anchors, respectively, the second ends of the pairs of connecting elements extending from the foundation;
- leveling, aligning, and fixing a ring structure relative to an upper surface of the foundation, wherein leveling, aligning, and fixing includes producing a gap between a surface of the ring structure and an upper surface of the foundation, the ring structure having openings, the second ends of the pairs of connecting elements extending through the openings of the ring structure;
- placing a grouting material in the gap;
- setting of the grouting material;
- placing a lower flange ring of a pylon segment on an upper surface of the ring, the lower flange ring having openings, the second ends of the pairs of connecting elements extending through the openings of the lower flange ring;
- and
- coupling the lower flange ring to the ring structure.

A method of erecting a pylon, the method comprising:
- forming a foundation that includes a plurality of segment anchors that are spaced apart from each other and radially arranged about a central axis of the foundation, wherein forming the foundation includes coupling first ends of pairs of connecting elements to the plurality of segment anchors, respectively, so that second ends of the pairs of connecting elements extend from the foundation;
- leveling, aligning, and fixing a leveling ring over an upper surface of the foundation and thereby forming one or more gaps between a surface of the leveling ring and an upper surface of the foundation;
- filling the one or more gaps with a grouting material;
- setting the grouting material;
- placing a lower pylon segment with a lower flange ring on the leveling ring;
- and
- coupling the lower flange ring to the leveling ring.
