Abstract

A wind energy plant foundation is provided with a plurality of ready-made concrete foundation segments. The foundation segments have a plurality of first and second sheaths which serve to receive tension wires for bracing the foundation segments.

First claim

1 . A foundation for receiving a wind energy plant tower with a plurality of tower segments, the foundation comprising:
a plurality of pre-formed concrete foundation segments, each foundation segment having a plurality of first and second sheaths that are configured to receive tension wires for bracing the foundation segments, wherein each foundation segment has an under side, an upper side configured to receive a lower tower segment of the plurality of foundation segments, an inner side, an inwardly curved outer side, two side faces and an outer section, wherein the plurality of first sheaths extend parallel to the under side of the foundation segment and the plurality of second sheaths extend between the outer section and the upper side of the foundation segment or parallel to the two side faces.

2 . The foundation according to claim 1 wherein the plurality of second sheaths follow a curvature of the inwardly curved outer side.

3 . The foundation according to claim 1 , further comprising a plurality of segment anchors on the outer section in the region of the ends of the second sheaths for receiving an end of a tension wire for bracing the foundation segment.

4 . A wind energy plant comprising:
a wind energy plant foundation including: a plurality of pre-formed concrete foundation segments, each foundation segment having a plurality of first and second sheaths that are configured to receive tension wires for bracing the foundation segments, wherein each foundation segment has an under side, an upper side configured to receive a lower tower segment of the plurality of foundation segments, an inner side, an inwardly curved outer side, two side faces and an outer section, wherein the plurality of first sheaths extend parallel to the under side of the foundation segment and the plurality of second sheaths extend between the outer section and the upper side of the foundation segment or parallel to the two side faces, and tension wires located in the first and second sheaths, wherein the foundation segments are braced by the tension wires in the first and second sheaths.

5 . The wind energy plant according to claim 4 further comprising a lower tower segment placed on the upper side of one or more of the plurality of foundation segments, wherein the lower tower segment is braced together with the plurality of foundation segments by tension wires in the second sheaths.
