Abstract:
1. A wind power installation comprising: a foundation with a plurality of segment anchors embedded therein, the plurality of segment anchors being radially arranged; a leveling ring which is aligned and fixed on a top side of the foundation, the leveling ring having an upper surface that is level to provide in situ leveling of pylon segments while erecting a pylon, the leveling ring including a plurality of circumferentially spaced holes at an outer circumference of the leveling ring and a plurality of circumferentially spaced holes at an inner circumference of the leveling ring; a pylon which has at least one pylon segment, the at least one pylon segment including a lower pylon segment that includes a lower flange ring and a pylon wall plate, the lower flange ring including a plurality of circumferentially spaced holes at an outer circumference of a width of the leveling ring and a plurality of circumferentially spaced holes at an inner circumference of the leveling ring, the lower pylon segment being located on the leveling ring, the lower flange ring of the lower pylon segment being on top of the leveling ring; a plurality of pairs of single, integral, continuous, uninterrupted bolts, each of the segment anchors coupled to a respective pair of the single, integral, continuous, uninterrupted bolt, wherein each single, integral, continuous, uninterrupted bolt of the pairs of bolts has a first end coupled to the respective segment anchor and a second end that projects a predetermined distance above a top side of the foundation, each single, integral, continuous, uninterrupted bolt of the pairs of bolts being positioned on opposite sides of the pylon wall plate; a gap located between the top side of the foundation and the leveling ring that is produced by aligning and fixing the leveling ring; a grouting material that has been placed in the gap after the upper surface of the level ring has been leveled, each single, integral, continuous, uninterrupted bolt extending from a respective one of the plurality of anchors embedded in the foundation, through the grouting material, through the leveling ring, and through the lower flange ring of the pylon segment, one of single, integral, continuous, uninterrupted bolts of each pair extending through a hole in the outer circumference of the leveling ring and the lower flange ring and the other of the pair of the single, integral, continuous, uninterrupted bolts extending through a hole in the inner circumference of the leveling ring and the lower flange ring; and a nut coupled to the top end of each of the bolts of the pairs of the single, integral, uninterrupted bolts, overlying the lower flange ring of the pylon segment and holding the lower flange ring in a butting contact with the leveling ring.
