Definitions

  • the invention relates to a foundation system for supporting structures, a foundation element and a use of a foundation element and a foundation system. Furthermore, the invention relates to a method for producing a foundation system and a foundation element.
  • Foundation elements are generally known. For foundation foundations in poor soil conditions, for example, foundation piles are arranged below the foundation, so that the foundation piles sit on a supporting floor arranged below the non-load-bearing floor and support the foundation.
  • Foundations of wind turbines are usually carried out so that wind turbine superstructures on a flat, lying on a foundation foundation, which can easily consist of 350 to 600 m 3 , in rare cases up to about 900 m 3 and more, concrete, are placed.
  • the attacking wind creates tensions in the foundation, in the bottom joint and the underlying ground.
  • In defined load positions or load cases as a result of the eccentric load attack, increased edge and corner stresses occur, in part, with the approach of a gaping of the bottom joint.
  • the load attacks also induce cracks or changes in the foundational element, which reduces their service life.
  • the object of the invention is to ballastieren by suitable measures the foundation or the foundation structure so that the above-mentioned disadvantages are avoided.
  • a foundation system for ballasting structures comprising a foundation and a foundation element, wherein the foundation element comprises a foot portion and at least one anchor and wherein the foundation element is braced by means of the anchor to the foundation.
