  • a basic idea of the invention is the separation of the anchor part into individual functional modules.
  • a screw-wing base segment is provided, which can be arranged according to the requirement for anchoring in almost any number of an anchor tip module in series. It can be assembled according to requirements in the modular principle in a simple manner various types of ground anchors with different anchoring properties.
  • the individual modules can be produced in large numbers and thus cost.
  • a further increase in the variety of screw anchors to be produced is achieved according to the invention in that sleeve-shaped spacer modules are arranged between individual screw-thread module or groups of screw-thread module.
  • the additional use of distance modules is based on the finding according to the invention that the greatest possible increase in anchoring strength is achieved when using multiple screw-thread modules just when larger bottom sections remain between the individual screw-wing modules or groups of screw-wing modules from two, three or more screw-wing modules.
  • a particularly large increase in strength at the same time the smallest possible axial length of the anchor member is achieved according to the invention in that the length of the spacer module corresponds approximately to three times the outer diameter of the ffererielwindung.
  • a further simplification in the manufacture and installation of the ground anchor is achieved according to the invention in that the individual modules are connected to one another via an identically formed module connection.
  • the same module connection is provided on all modules, even if they have different functions or size. This allows a high combination of combinations.

  • the turret modules can be combined in any way with the distance module and strung.
  • the anchor tip module has on the opposite side of the armature tip according to only one connection side, to which a distance module or a screw-wing module can be connected.
  • other modular forms, such as injection ports or special additional anchoring components are possible.
  • the module connection is formed as an axial plug connection.
  • the axial connector allows a torsionally rigid connection of the individual modules at least in the screw-in direction of rotation.
  • the connector may for example consist of square or polygonal bolts on one side of the connection and corresponding square receiving holes on the other side of the connection module.
  • connection side and the second connection side are identical. It is provided as a further inventive feature that recesses and claws are formed on both sides of the connection corresponding to each other.
  • the non-rotatable connection of the individual modules is made, so to speak similar to a dog clutch.
  • a further preferred embodiment according to the invention is that a built-in part is provided, which is connected when screwing for torque transmission to the anchor part via a detachable connection, that this is removable on reaching a predetermined position of the anchor part of this detachable and from the ground and in that the releasable connection between the anchor part and the built-in part corresponds to the module connection.
  • a built-in part is provided, which is connected when screwing for torque transmission to the anchor part via a detachable connection, that this is removable on reaching a predetermined position of the anchor part of this detachable and from the ground and in that the releasable connection between the anchor part and the built-in part corresponds to the module connection.
  • the insert is designed as a tubular sleeve.
  • the tension element is arranged, which extends from the anchor part to the bottom surface.
  • the screw module has at least one screw with a quarter, half or full helix. From these segments it is also possible to assemble elements with a plurality of screw thread windings, wherein the screw wings of the individual modules in the assembled arrangement are flush with each other. It is also possible to combine modules with screw-type wings of different shapes and numbers.
  • the composite anchor part and the mounting part enclose an inner channel, in which the tension element is arranged.
  • the tension member may be a rigid pull rod or a so-called tension cord, which can be rolled up on a drum.
  • a curable suspension or another fluid medium can be introduced into the soil through the channel.
  • the anchor tip has an opening in which the channel opens. In this way, an additionally injected medium in the region of the anchor point emerge from the channel and thus cause an additional increase in consolidation.
  • a bottom end of the tension member is attached to an anchor tip module and that the anchor tip module is connected to at least one screw wing module.
  • This manufacturing method is based in particular on the use of a previously described ground anchor with the individual ground anchor modules.
  • the Ground anchor can be assembled by the manufacturer and sold as a finished product or assembled directly from the individual modules by the user himself. In both cases, there is a corresponding cost advantage in the production and thus when using the ground anchor.
  • the method according to the invention for anchoring a tension element in the ground is characterized in that the anchor part is assembled according to a required anchoring strength from an anchor tip module and one or more screw flight module.
  • the shape and size of the ground anchor to be assembled is first determined on the basis of the load to be absorbed by the tension element and the given soil properties.
  • the armature part is then assembled from the armature tip module and the previously determined number of screwed-wing modules and optionally further modules, such as spacer modules. Subsequently, the ground anchor thus assembled is screwed into the ground using a built-in part.
