Definitions

  • the invention relates to a method for producing a foundation for a building in the water in which a tubular hollow body is arranged at the bottom of the water, a drilling device is arranged in the hollow body, in the bottom of the water a cavity below the hollow body is generated, in which the soil is removed by means of the drilling device , and the hollow body is lowered into the cavity until a predetermined depth in the soil is reached, the drilling device is then removed from the hollow body, a foundation element is introduced and lowered into the cavity in the interior of the hollow body, and the space between the cavity wall and the outside of the foundation element is filled.
  • the invention relates to a system for producing a foundation for a structure in the water with a tubular hollow body, with a drivable in the hollow body boring device, which is adapted to produce in the bottom of the water a cavity below the hollow body, in which the soil is removed by means of the drilling device , And in which the hollow body is lowered, with a foundation element, which is embeddable and lowerable into the cavity in the interior of the hollow body, and with a filling material that is suitable, a gap, which after removal of the hollow body between the cavity wall and the outside of the Foundation element is present, to fill.
  • a platform is arranged at a foundation site, which is a guide element for a having to be introduced monopile.
  • the monopile is placed in the soil and then the annulus is filled between the monopile in the soil.
  • a wind turbine is installed via a connecting section.
  • the foundation structure is divided into two parts, in which a monopile is first introduced, in which then subsequently a second tubular element is set, on which then the connection adapter and on the turn the wind turbine are applied.
  • a lost formwork is placed in the ground in which then the monopile is placed on the then the connection adapter and the wind turbine are placed.
  • a jack-up platform or a comparable carrier vehicle is provided at the foundation site, with which in particular the guidance of the monopile during the introduction is accomplished. The use of such jack-up platforms is expensive.
  • the invention provides that at the place of foundation a guide device is placed on the water base surface, in which the tubular hollow body is arranged in the guide device in the insertion direction, that the hollow body is removed from the cavity after the introduction of the foundation element , And that the guide element is removed.
  • the guide device is deposited as a separate unit on the water base surface.
  • the tubular hollow body is used, which acts as a kind of casing.
  • the drilling device is introduced, which then subsequently removes the soil in the foundation area.
  • the casing is optionally introduced controlled by the guide device. Once the casing has been inserted into the ground to its final depth, drilling is stopped and the drilling device removed from the casing.
  • a further teaching of the invention provides that the guide element is removed before or after the introduction of the foundation element in the hollow body. Furthermore, it is advantageous that the hollow body is closed after removal of the drilling device with a closure element, wherein preferably before the introduction of the foundation element, the closure element is removed and / or it is preferably in the closure element is a lid. By closing the hollow body, it is possible, especially in waters with strong currents or high sediment content to close the hollow body to prevent material entry in a simple manner.
  • Another teaching of the invention provides that a cementitious material is used to fill the cavity between the cavity wall and the foundation element. This makes it possible in a particularly simple manner to achieve a corresponding fixation of the foundation element in the ground. Furthermore, it is advantageous that the foundation element is a pile. Furthermore, it is advantageous that the building is a wind turbine.
  • the solution according to the invention provides that a guide device is provided, which is deductible at the foundation on the water base surface and in which the hollow body can be arranged in the direction of insertion, and that the hollow body is designed so that it is after the introduction of the foundation member of the Cavity is removable.
  • An advantageous embodiment of the invention provides that a closure element is provided, with which the hollow body is closable. This is preferably a lid.
  • the foundation element is a pile, and / or that the backfill material is a cementitious material.
  • a guide device 13 is arranged in the water 11 on the ground 12 (see Fig. 1 ).
  • the guide device 13 has a pipe section 14 which is connected to a flat support body 15 on the body of water 12.
  • To support diagonal struts 16 are arranged between the pipe section and the support body.
  • a hollow body arranged in the form of a casing 18.
  • a drilling device 20 is arranged in the interior 19 of the casing 18. With a drill head 21 of the drilling device 20 located in the removal area to be solved bottom 22 is removed. This creates a cavity 23, in the progress of Bohrfort suits (see Fig. 4 ) the casing tube 18 is lowered into the cavity 23.
  • the drilling device 20 is removed from the interior 19 of the casing 18.
  • Fig. 6 can then be applied to the closing of the interior 19 of the casing 18, a cover member 25 on the projecting into the water 11 end 26 of the casing, so that then the interior 19 is closed to material input by inflowing water.
  • the thus-prepared foundation site 10 can now be found in the in Fig. 6 state shown remain until the subsequent construction steps of the structure 100 are performed.
  • Fig. 7 is shown, the lid 25 removed and then, as in Fig. 8 is shown, introduced into the interior 19 of the casing 18, a foundation pile 27 and parked on the cavity deepest. Subsequently, the casing tube 18 is removed from the cavity 23, as in Fig.
  • annular space 30 Between the outer wall 28 of the cavity 23 and the outer wall 29 of the foundation pile 27 thus there is an annular space 30 (see Fig. 10 ).
  • a filling material 31 is introduced and the previously located in the annular space 30 water displaced thereby. This is continued until the filling material 31 in the annular space 30 has reached the height of the body of water 12.
  • the guide device 13 After hardening of the filling material 31, the guide device 13 is then removed and the foundation pile 27 is located free-standing in the body of water 11 starting from the water bottom 12.
  • a connecting element 32 is then arranged on the foundation pile 27 (see FIG Fig. 14 ), on which then the wind turbine 100 (see Fig. 15 ) is built.
