Abstract
A wind turbine foundation and method for making a wind turbine foundation. The wind turbine foundation preferably includes a core member including a substantially cylindrically-shaped main body, a first outer flange extending out from the main body along an upper section of the core member, and a second outer flange extending out from the main body along a lower section of the core member, and a plurality of radial girders connected to the first outer flange and the second outer flange and radiating out from the core member.
Claims8
A wind turbine foundation comprising:
- i. a metal spool;
- ii. a plurality of metal radial girders connected to and radiating out from the metal spool;
- and
- iii. a ring girder connected above the plurality of radial girders wherein the ring girder further comprises a tower flange including a plurality of apertures for attaching a wind turbine tower to the ring girder.
A method of erecting a wind turbine foundation, the method comprising the steps of:
- i. excavating a foundation area in the ground by removing excavated soil from the ground;
- ii. pouring a mud slab in the excavated foundation area to create a level work surface;
- iii. placing a metal core member in the excavated foundation area;
- iv. attaching a plurality of metal radial girders to the core member wherein the plurality of metal radial girders further comprise upper girder flanges;
- and
- v. connecting a ring girder above the plurality of radial girders wherein the ring girder further comprises a tower flange including a plurality of apertures for attaching a wind turbine tower to the ring girder and a lower ring girder flange for attaching the ring girder to the upper girder flanges of the plurality of metal radial girders.
