tower foundation system, wind turbine and / or wind tower, and procedure for installing a tower foundation system.

摘要

tower foundation system, especially for onshore wind towers, comprising a buried or partially buried central shaft, preferably hollow and formed of prefabricated concrete segments, an essentially flat and fully buried lower slab, and shaped lateral support means of inclined struts that join at its upper end with the central shaft and at its lower end with the lower slab, and which are preferably buried in their entirety. the wind tower is located on the semi-buried central shaft. The foundation system may comprise other lower members connected to the lower slab such as radial ribs or perimeter beams. The struts are preferably prefabricated elements incorporating an efficient and economical strain relief connection system. The foundation system makes it possible to maximize the fraction of the foundation weight by gravity that is generated with ground or ballast material, allowing for significant savings in cement structural materials.
