Definitions

  • the subject of the invention is a gravity structure intended for a maritime civil engineering construction and a related manufacturing method.
  • a known gravity structure comprises a raft configured to be laid on a sea floor and secured to a barrel directed in a main direction substantially orthogonal to the floor.
  • the maritime civil engineering construction for which such a gravity structure is intended is for example a wind turbine at sea or a bridge.
  • the shaft In the service position, that is to say when the gravity structure rests on the sea floor, the shaft is disposed substantially vertically and is surmounted by a mast itself equipped with a nacelle and pale when the maritime construction is a wind turbine, surmounted by a pile and an apron when the construction is a bridge.
  • the raft provided in the form of a cylinder, must have a very large diameter, of the order of a few tens of meters, which implies that the area of marine soil to be prepared is itself very wide.
  • ballast sand it is necessary to fill the drum with ballast to complete the installation of the gravity structure, which is all the more expensive as the material, for example ballast sand, must be routed from a port or a dredging area.
  • the object of the invention is to at least partially overcome these disadvantages.
  • the subject of the invention is a gravity structure intended for a maritime civil engineering construction, comprising a raft configured to be laid on a sea floor and secured to a barrel directed in a main direction that is substantially orthogonal to said raft, characterized in that the gravity structure comprises at least one anchor extending in said barrel and in the raft, the gravity structure being configured so that, in a service position of the gravity structure, said at least one tie rod anchor is anchored in said ground

  • the reduced dimensions of the gravity structure ensure that the forces exerted on the gravity structure by the swell are weaker.
  • Another advantage of the invention lies in the fact that the anchor or tie rods pre-force vertically the barrel of the gravity structure, which, on the one hand, improves the stability of the gravitational structure and, on the other hand, on the other hand, possibly reduces the number of other prestressing devices to be provided for the drum.
  • An additional advantage is that, due to the reduced size and weight of the gravity structure according to the invention, a water filling of the barrel is sufficient to ensure the stability of the gravity structure on the sea floor.
  • the method of manufacturing the gravity structure according to the invention overcomes the transport and filling of the ballast material which is necessary for the gravity structure according to the state of the art, as already mentioned.
