FUNDAMENT FÜR EINE WINDKRAFTANLAGE
The invention relates to a foundation for a wind turbine, wherein the foundation (10) comprises substantially prefabricated elements, preferably made of reinforced concrete, with a first, vertically extending pedestal-like section (11), on which a tower of the wind turbine can be arranged, with a second, substantially horizontally extending section (12) as foundation body, which is in contact with the ground (100) and which has at least two horizontal elements (22) with at least one bearing section (25) at the inner end thereof, wherein the first section (11) is arranged above the at least two bearing sections (25) of the second section (12), and with a third section (12a) which is arranged below the at least two bearing sections (25) of the second section (12). There is provision here according to the invention that a pedestal (20) is provided which is formed at least from the first, vertically extending pedestal-like section (11), from the at least two bearing sections (25) of the second section (12) and from the third, vertically extending pedestal-like section (12a), that the three sections (11, 12, 12a) here form at least three layers (13, 16, 17) arranged over one another, of which the upper and the lower layer (13, 17) is formed from at least two ring-like layers (13a, 13b, 17a, 17b), and the central layer (16) is formed from at least one ring-like layer (16a), that the height (H+I, 2xJ) of the upper and/or lower layer (13, 17) is less than the height (K) of the central layer (16), and that the layers (13, 16, 17) are vertically braced with the second section (12) by means of at least two vertical tensioning members (19).
