Foundations system for towers and method for installing the foundations system for towers

摘要: Foundation system for towers, especially onshore wind turbines, comprising a central shaft buried or partially buried, preferably hollow and formed by dowels made from precast concrete, an essentially flat lower slab completely lateral support means in the form of inclined struts that are joined at their upper end with its slab, entirely buried. The tower is located on partly main shaft. foundation may comprise other elements connected such as radial ribs peripheral beams. prefabricated incorporating efficient economical connection pre-stressing. maximizes fraction weight gravity generated soil ballast material, allowing important economy structural materials foundation.
