Definitions

  • the invention relates to an offshore structure with a foundation structure, the foundation structure having at least a first and a second profile, the first profile being designed as a pile and the second profile as a pile sleeve, the second profile enclosing the first profile over a penetration length, with a gap is formed between the first and the second profile, the gap has a casting compound filling over the entire penetration length, on the first and / or the second profile thrust elements are provided and the thrust elements extend into the gap and effect an axial load transfer into the casting compound filling.
  • Such structures are for example from the publication DE 10 2012 020871 A basically known.
  • the invention relates to an offshore structure as defined in claim 1 and in particular to a cast connection on such an offshore structure.
  • a cast connection is referred to in technical jargon as a so-called "grouted joint".
  • Grouted joints are structural elements that are decisive for the structural integrity of offshore structures and are usually the only connection between a foundation structure or a foundation and a supporting structure.
  • Such connections can be found, for example, in so-called monopile foundations between the monopile and a transition piece.
  • Grouted joints can also be found, for example, in jacket foundations, which are made up of profile piles and pile sleeves. Especially when it comes to founding In offshore wind turbines, casting compounds of the type mentioned at the beginning play an essential role.
  • connections usually comprise two cylindrical steel pipes of different diameters, which are connected to one another by a grouting mortar.
  • the tube with the smaller diameter is usually referred to as a pile, while the larger, enclosing tube is referred to as a pile sleeve or sleeve.
  • the space remaining between the pile and the sleeve is filled with a grouting mortar or a grouting compound, which is also known as a grout in technical jargon.
  • Potting compound connections or potted connections of this type are primarily used to transfer axial loads of the structure into the seabed. The compressive strength of the potting compound after it has hardened is decisive for the load-bearing behavior of potted connections.
  • shear ribs are ribs, projections, webs or the like, which are attached to the mutually facing sides of the profiles and which protrude into the space between the profiles in such a way that they are enclosed by the potting compound.
  • shear ribs By using shear ribs, axial loads are transferred to the grouting mortar via the contact surfaces. This increases the size of the thrust-transmitting contact surfaces.
  • the invention is therefore based on the object of providing an offshore structure or a cast connection on an offshore structure which is improved with regard to the load-bearing and failure behavior.
  • One aspect of the invention relates to an offshore structure with a foundation structure, the foundation structure having at least a first and a second profile, the first profile being designed as a pile and the second profile as a pile sleeve, the second profile enclosing the first profile over a penetration length, wherein a gap is formed between the first and the second profile, the gap has a casting compound filling over the entire penetration length, on the first and / or the second profile thrust elements, for example in the form of thrust ribs or the like, are provided, the thrust elements extend into the gap and an axial load transfer in cause the potting compound filling, the thrust elements being provided only over a first partial length of the penetration length, the first partial length being between 65 and 90% of the total penetration length and a second partial length being free of thrust elements, the second partial length being the upper length of the penetration length in the installed position forms.
  • the structure is characterized in that the first profile and / or the second profile have an adhesion-reducing coating over the second partial length (L2) on the side facing the gap and / or between the first profile and / or the second profile and the casting compound filling the second partial length (L2) of the penetration length is a layer made of an elastic material, such as an expanded thermoplastic material.
  • These diagonally formed compression struts preferably generate corresponding reaction forces on the underside of the thrust elements, so that it has surprisingly been found to be particularly advantageous to provide the thrust elements only over part of the length of the penetration length, and in particular that area of the penetration length or the potting length that is in the installation position of the profile is at the top, free of thrust elements This advantageously prevents a loss of potting compound or a swelling out or sliding out of the potting compound from the enclosure of the profiles, whereby the load-bearing strength of the potted connection is significantly improved.
  • a design of the cast connection or of the offshore structure has proven to be particularly advantageous in which the second part length has a length between the is one and two times the width of the gap.
  • the space between the profiles can be, for example, about 500 mm wide.
  • the diameter of the second profile can be approximately 2.5 to 3 m, for example.
  • a hydraulically setting casting compound for example a high-strength concrete, is provided as the casting compound.
  • the profiles are preferably designed as cylindrical steel tubes, one steel tube being designed as a pile and the other steel tube as a sleeve.
  • the profiles can be part of a connection between the monopile and the transition piece of an offshore structure.
  • the profiles can alternatively be part of the foundation of an offshore structure with a jacket.
  • the presence of the adhesion-reducing coating or the layer made of an elastic material can ensure that the shear stresses arising from a relative movement of the profiles to one another are introduced into the potting compound only over the first part of the penetration length or only over a first part of the potting length. In this way it is ensured that a sealing compound plug remains in the upper area of the sealed connection, the integrity of which is not impaired by shear stresses introduced into the sealing compound.
  • the adhesion-reducing coating can preferably be provided either on the inside of the second profile facing the interspace or on the outside of the first profile facing the interspace, depending on which profile is subject to compressive and tensile loads in the axial direction. In the case of a jacket, for example, this can depend on whether the jacket was attached by pre-piling or post-piling.
  • a layer made of an elastic material preferably made of an expanded thermoplastic, is provided between the first profile and / or the second profile and the potting compound filling over the second partial length of the penetration length or the potting length.
  • the potting compound filling can have a first potting compound over the first partial length of the penetration length and a second potting compound over the second partial length of the penetration length, the second potting compound having a higher tensile and / or compressive strength than the first potting compound.
  • the second potting compound can be fiber-reinforced or reinforced.
  • the second casting compound can be designed as a fiber concrete.
  • the second potting compound has a higher ductility than the first potting compound.
  • the casting compound filling receives an insert component over the second partial length (L2) which is selected from a group of insert components comprising precast concrete elements, steel profiles and polymer building materials, the insert component having a higher tensile and or compressive strength than the casting compound.
  • a design of the encapsulated connection on the offshore structure has proven to be particularly advantageous in which the intermediate space is at least partially closed on the upper end face in the installed position.
  • the pile sleeve has an upper, inwardly protruding collar which partially covers an upper end face of the space in the installed position and thus prevents any brittle casting compound from emerging or swelling out.
  • the post has a collar or collar which closes the gap at the end.
  • reinforcement is attached to the first profile or to the second profile, which reinforcement extends over the second partial length of the penetration length.
  • the reinforcement is expediently provided on that profile that is not subject to alternating tensile and compressive loads.
  • the invention relates to an offshore structure 1 and in particular to a cast connection on an offshore structure 1.
  • the invention is described below with reference to an offshore structure 1 with a jacket foundation.
  • the principle of the encapsulated connection according to the invention can be transferred to different types of connections on offshore structures.
  • the offshore structure 1 comprises, for example, a tower structure 2, a transition piece 3, a so-called jacket 4 and an anchoring of the jacket 4 in the sea bed 5 in the form of piles 6 (piles) and pile sleeves 7 (sleeves).
  • the offshore structure 1 shown was founded by what is known as pre-piling, ie the piles 6 were driven into the sea bed 5 using a template and appropriate tools.
  • the pile sleeves 7, which are fastened to the jacket 4, were placed on the driven piles 6, whereby these penetrate the pile sleeves 7.
  • An intermediate space 8 or annular space between the piles 6 and the pile sleeves 7 was potted with a hardenable potting compound 11, for example a fiber concrete or the like.
  • FIG. 2 Another variant of the pile foundation is in Figure 2 shown. This type of formation is generally referred to as post-piling.
  • the pile sleeves 7 are first driven into the sea bed 5.
  • the feet of the jacket, which are each designed as a pole 6, are inserted into these.
  • the space between the pile 6 and the pile sleeve 7 is also filled with a hardenable potting compound.
  • FIGS. 3a and 3b show the typical loading of the casting compound 11 when tensile or compressive forces are introduced, for example via the pile 6 in the case of a foundation, as shown in FIG Figure 2 is shown. With those in the Figures 3a and 3b The direction of loading is indicated by arrows 9.
  • the inner profile is a cylindrical pile 6, whereas the outer profile, which encloses the inner profile, forms the pile sleeve 7.
  • the space 8 is filled with a grouting mortar or a hydraulically setting grouting compound 11.
  • diagonal compression struts 10 arise between the pile 6 and the pile sleeve 7, which under certain circumstances have the effect that the casting compound 11 is pressed upwards out of the space 8.
  • the tendency of the casting compound 11 to move is indicated by the arrows 13
  • Figure 4 shows a partial longitudinal section through a cast connection according to the invention.
  • the formation of the grouted joint in the form of two penetrating cylindrical steel profiles as a pile 6 and pile sleeve 7 corresponds to the design according to Figures 3a and 3b .
  • the pile 6 and the pile sleeve 7 penetrate one another over a penetration length L total which corresponds to the potting length or the height of the potting compound 11 located in the intermediate space 8.
  • the total penetration length L is divided into a first partial length L1 and a second partial length L2, the second partial length L2 being the upper partial length in the installation position of the pile sleeve 7 and the first partial length L1 forming the lower partial length.
  • the partial length L2 of the penetration length is free of thrust elements.
  • the thrust ribs 12 are only provided in the area of the first partial length L1 of the penetration length.
  • the height of the second partial length L2 corresponds approximately to one to two times the width of the space 8 (0.5 x (inner diameter of the pile sleeve minus outer diameter of the pile)).
