  • the wings 19 can be arranged by welding to the edge 18 of the fins 8 and to the ring 17.
  • the device 1 or tube 2 is provided with a fastening element 28 in the shape of, for example, a square, rectangular, circular, oval or the like plate and which is attached to the second or upper end edge 6 of the tube 2 by means of, for example, welding, there is no need for a reinforcement 17, strengthening device or ring, as the plate or the like at this at the same time serves as a reinforcement device or a holding together and stabilizing device for the tube 2, see Fig. 18.
  • a fastening element 28 in the shape of, for example, a square, rectangular, circular, oval or the like plate and which is attached to the second or upper end edge 6 of the tube 2 by means of, for example, welding, there is no need for a reinforcement 17, strengthening device or ring, as the plate or the like at this at the same time serves as a reinforcement device or a holding together and stabilizing device for the tube 2, see Fig. 18.
  • a fastening element 28 When a fastening element 28 is arranged it will cover the end of the device 1 or tube 2, whereby a compressing device 20 cannot be inserted in the inside 4 of the tube 2 for compressing of the basis 11 within the tube 2.
  • a disc-shaped element or a plate is at this arranged in the inside 4 of the tube 2 and that the fastening element 28 is provided with a through hole 33 or a centrally located, small hole, through which an implement can be led for influence on the disc-shaped element for com ⁇ pressing of the basis 11 in the tube 2, see also Fig. 19.
  • the tube can be provided with more inward bendings or similar to form more fins, folds or similar, for example six fins or folds, as well as more edges directed upwards and downwards.
  • the device or tube shows at least one fin or fold and one break or opening, recess or similar.
  • breaks and/or openings make the expansion of the tube easier when compressing the basis in the tube because of the weakening they form. Instead for removing material when the tube is broken through or slit up one can, as mentioned, let the material remain in the tube in a material part, whereby expandable tongu ⁇ es are attained, which can be brought to expand by the compressing of the basis in the tube.
  • the basis can at this also be brought to penetrates out through the slits or the formed openings or similar. It should also be possible to arrange breaks, slits, openings or similar in several lines above one another and/or with mutual division. It is an advantage if the unmoved basis is held intact and hard or compact before and during the entering or introduction of the device or tube into the basis or that one in advance makes the basis up to even harder or more compact, i.e. that the basis is packed before the anchoring operation.
  • the methods and devices shown and described by the embodiment examples are thus not restricted to what has been evident by the embodiment examples but soley by the following claims.

Abstract

Dans un procédé et un dispositif conçu pour réaliser un ancrage dans le sol ou pour ancrer des objets dans le sol, on utilise un dispositif d'ancrage (1) comprenant un tube (2). La paroi (3) du tube (2) est fracturée ou bien des parties de matière sont retirées pour former au moins un creux (9), des ouvertures (10) ou similaire dans le tube (2). La paroi (3) du tube (2) est formée de courbures (7) intérieures ou similaires pour former des nervures (8) ou similaires le long du tube (2). Le tube (2) est ensuite inséré dans le sol jusqu'à une profondeur telle que les creux (9), les parties du tube (2) présentant les portions évidées, les ouvertures (10) ou similaires et/ou au moins une partie desdites nervures (8) ou similaires soient situées au-dessous du niveau du sol. Ensuite, le sol introduit à l'intérieur du tube (2) peut être, dans certains cas, comprimé ou tassé au moyen d'un dispositif de compactage ou de tassement introduit dans le tube. Le tube (2) peut être pourvu d'ailettes (19).
