Embodiment Construction
[0034] Fig. 1 schematically shows a wind turbine foundation according to a first embodiment of the invention.
[0035] Referring to FIG. 1 , there is a wind turbine 100 comprising a rotor 102 provided with a set of blades 104 . The rotor 102 is disposed on top of a tower 106 , which is anchored to a foundationsole 116 , shown here embedded in the ground 112 .
[0036] Tower 106 is typically made of steel, whereas base platform 116 is made of reinforced concrete. In order to anchor the steel tower 106 to the foundation platform 116 a flange 114 with a through hole 115 is provided at the bottom of the steel tower. In addition, the base platform 116 is provided with a corresponding set of through holes 118 . Thus, by placing the tower on the upper surface of the base table 116, aligning the through-holes 115 in the flange with the through-holes 118 in the base table 116, inserting through-bolts 120 into the aligned holes , and fix the nuts 121a, b at the upper and lower ends o...
