Embodiment Construction

[0054] figure 1 A foundation 1 for a wind turbine tower 2 is described. The foundation 1 is adapted to engage the lower part of the tower 2 and provide a stable support for the tower 2 . The tower 2 may be formed in the circumferential direction from a plurality of tower segments, each tower segment forming a part of the tower 2 . In vertical direction, the tower 2 may be formed from a plurality of tower sections, one tower section being placed on top of the other.

[0055] The base 1 is particularly suitable for placement on rocky or rocky ground.

[0056] The foundation 1 includes a rock fixing flange 10 . The shape of the rock flange 10 corresponds to the shape of the periphery of the tower 2 . For example, the rock anchor flange 10 may be as figure 2 The ring shown, or any other shape that roughly corresponds to the shape of the tower 2 . A plurality of anchors 16, 17 are provided for fastening the foundation to the ground 3.

Abstract

The invention involves a foundation (1) for a wind turbine tower (2), comprising a rock flange (10) having a first set of through anchor holes (14) each arranged to extend in a non-zero first angle to, or parallel to, a longitudinal direction (LT) of the wind turbine tower when erected, and a second set of through anchor holes (15) each arranged to extend in a non-zero second angle to the longitudinal direction (LT) of the wind turbine tower when erected, wherein the first and second angles are different from each other, and wherein upper ends of the anchor holes in the second set of anchor holes are located internally of the foundation.

Description

technical field [0001] The present invention generally relates to foundations for wind turbine towers. The invention also relates to a method for forming a foundation of a wind turbine tower, a rock fastening flange for a wind turbine tower, a wind turbine comprising such a foundation, and the use of such a foundation in a wind turbine. Background technique [0002] Wind turbine towers are typically 30-80m high and 2-10m in diameter. Typical modern tower weights are 40 tonnes for a 50m tower for a 44m rotor diameter turbine (600kW) and 80 tonnes for a 60m tower with a 72m rotor diameter. Due to the height and weight of the wind turbine tower, the forces created by the rotational motion of the wind turbine blades, and the very large surface of the tower exposed to the wind, the tower must be easily secured to the ground. [0003] Depending on the soil conditions (eg rock, mud or gravel), different types of foundations are used to secure the wind turbine tower to the ground....
