Definitions

  • the invention relates to a swivel module for use in creating an underwater foundation of a building.
  • so-called jackup rigs are provided at monopiles at the construction site, the working plane of which is provided with a slewing mechanism.
  • the pole In this swinging the pole is clamped, deflected from the horizontal to the vertical and lowered by opening the clamps on the seabed.
  • the pile is then driven into the ground by means of pile driving.
  • a disadvantage of this foundation process is the dependence on the local geology. If the soil is provided with constituents which prove to be non-rammable, for example by solid rock or by the presence of loam layers in which the friction increases too much or the presence of boulders or the like, this process can not be used.
  • a further disadvantage of this method, especially in ecologically sensitive areas, is that high noise emissions emanate from this method.

  • Such a method provides that the pile is clamped in a swivel module, that the pile is erected by pivoting the swivel module until the desired propulsion direction is achieved in the ground with respect to the horizontal, that the stake deposited on the bottom of the water and until reaching a limit value of the feed force, it is moved into the bottom of a sinking device installed in the pile and lowered on the ground, that the rock is released below the pile and the pile is lowered until a final depth is reached.
  • the base element is a jack-up, a pontoon and / or a ship. This makes it possible, depending on the body of water, to provide a suitable basis for carrying out the method.
  • Another teaching here provides that the swivel module is locked after reaching the desired inclination. As a result, a higher accuracy is achieved.
  • the pile is designed as a cylinder or cuboid. These shapes are advantageous in terms of foundation construction and placement of the pile in the ground. Furthermore, it is provided that the pile has an inner diameter from 4 m and greater, with diameters of 11 m or more can be built.
