Abstract: The subject matter relates to a method and an apparatus for vibrating-in a foundation into a building ground by initiating vibrations generated by means of a vibrating device attached to the foundation, the vibrations causing liquefaction of the building ground so that the foundation penetrates the building ground.

Abstract: The application relates to a method for assessing the load bearing capacity of an inserted pile, including: applying, by a vibrator device arranged at the inserted pile, the inserted pile with a measuring pulse string during at least one vibration time period, detecting, by at least one detection module, motion data of the inserted pile caused by the measuring pulse string during a measuring time period, determining at least one downward motion data set from the detected motion data; and evaluating the downward motion data set such that a load bearing capacity criterion is determined.

Abstract: Supporting structure, in particular for a wind power plant, having at least two sub-segments which are at least partially connected to one another and are respectively formed from a metal plate having a longitudinal extent and a width extent. The longitudinal extent being greater than the width extent, and the sub-segments each having longitudinal edges extending in longitudinal extent and being connected to one another at mutually abutting joint surfaces along the longitudinal edges by a welded joint respectively. The sub-segments respectively have end edges extending in width, the sub-segments being bent along their end edges respectively. The respective welded joint has in sections a thickness which is smaller than a wall thickness of the metal plate and in sections a thickness which corresponds at least to the wall thickness of the metal plate.

Abstract: A method for installing a pile, in particular a monopile for a wind turbine, in a soil, comprising the method steps: —driving the pile into the soil using a vibration device; and—compacting soil material surrounding a lateral surface of the pile.

Abstract: The invention relates to an offshore installation, comprising an underwater foundation structure, a construction placed onto the foundation structure, a docking device for a boat, and a device for cathodic corrosion protection for the underwater foundation structure, said device having at least two anodes (2), which are arranged at a distance from each other and are each fastened to a beam (4) or a support of the foundation structure, the extension arms or the supports being connected directly to the foundation structure below the waterline.

Abstract: The invention relates to a support structure, in particular for a wind turbine, having at least two segments, which are joined to one another such that their longitudinal axes extend substantially collinearly to one another. At least one of the segments is a pipe section, which has at least two mutually facing abutment surfaces that are joined to one another, at least in parts. A support structure is provided that is producible in less time and is more cost-effective because the join between the abutment surfaces involves at least one welded join, the thickness of the welding join being less than the wall thickness of the pipe section, and/or the join between the abutment surfaces involves at least one retaining clip.

Abstract: The invention discloses a foundation pile having at least two interconnected part-cylinder segments which are each produced from a steel plate having a length extent and a width extent, wherein the foundation pile is characterized in that the respective part-cylinder segments are produced by bending the steel plates along their width extent, with the result that end edges extending along the width extent of the part-cylinder segments have a bending, in that a height extent of the respective part-cylinder segments is greater than their width extent, and in that the longitudinal edges of the part-cylinder segments that extend along the height extent of the part-cylinder segments are arranged parallel to one another. The present invention further discloses a method for producing a foundation pile according to the invention.

Abstract: The invention relates to a foundation pile comprising a stabilization device that is located within the foundation pile and is connected to at least two inner surface sections of the foundation pile; the stabilization device allows compressive and/or tensile forces to be transmitted such that the stabilization device counteracts lateral deformation and/or torsional deformation of the foundation pile.

Abstract: The invention relates to a method for constructing a foundation for a tower structure, comprising at least one structure-side connection profile in the form of a pipe segment. The method has the steps of providing a foundation pile with a diameter which differs from the diameter of the pipe segment, vibrating and/or ramming the foundation pile into a supporting substratum, aligning and fixing the pipe segment coaxially and concentrically to the foundation pile introduced into the substratum such that an annular space is formed between the pipe segment and the foundation pile, and filling the annular space with a curable casting compound.
