Definitions

  • the present invention relates to a method for drilling, in particular impact or rotary impact drilling, a hole in soil or rock material and for forming an anchor in the hole, a drill hole being formed by introducing a drill bit, and a device for drilling, in particular percussion or rotary percussion drilling, a hole in soil or rock material and for forming an anchor, a drill hole being formed by introducing a drill bit.
  • the drill pipe can be formed on its outer circumference with additional ribs and grooves, so that if the drill pipe remains in the borehole and is subsequently filled, a " correspondingly good anchorage effect can be achieved.
  • Borehole is introduced, for example EP-A 0 079 875, EP-B 0 047 727, EP-B 0 207 030, EP-B 0 016 742, EP-A 0 077 762, WO 97/31177, EP A 0 112 316, WO 91/06713, DE-A 40 24 869, WO 00/75489, DE-A 31 11 673 or US-A 4 636 115.
  • expandable anchor elements are introduced into the borehole, which are kept at a reduced diameter compared to the borehole when they are introduced into the borehole, whereupon they are expandable after being inserted into the borehole and during the Introduced folded or generally reduced in cross-section partial areas of the anchor device.
  • the folded regions do not readily permit a uniform expansion of the anchor device and thus a centered positioning of the anchor device, in particular if a plurality of anchor elements lying next to one another are provided.
  • a further disadvantage of this known prior art is the fact that the borehole must be produced in a first process step, after which, after removal of the drilling tool together with the drill pipe, the anchor device is introduced into the borehole, which may have a large length, after which it is subsequently carried out by widening the outside diameter of the anchor device, a plant on the borehole wall should succeed. It is immediately apparent that a correspondingly increased amount of time is required not only for the two separate work steps is necessary, but that a subsequent introduction of such an anchor device of great length may be difficult.
  • packers on the outer circumference of a drill pipe of a drilling device which, over a short partial area after completion of the drilling, permit widening in contact with the borehole wall and thus counteract pulling out or removing the drill pipe from the borehole.
  • packers cannot achieve a reliable anchoring effect, in particular when a plurality of anchors are to be provided next to one another, for stabilizing surrounding soil or rock material, so that additional means for anchoring, such as the application of hardening material, may have to be provided would.

  • At least one expandable element is introduced together with the drill pipe directly during the formation of the borehole, or the drill pipe is formed by an at least partially expandable element, so that a proper anchoring can be achieved after completion of the borehole with a simplified construction.
  • At least the outer circumference or the outer contour of the at least one expandable element at least partially expanded or enlarged to come into contact with the borehole wall.

L'invention concerne un procédé et un dispositif de forage, en particulier percutant ou rotopercutant, d'un trou dans une matière de sol ou rocheuse et de formation d'un ancrage, un trou de forage étant formé par l'introduction d'une couronne de forage (2). Selon la présente invention, les tiges de forage du dispositif de forage sont formées par au moins un élément expansible (3, 4), présentant une cavité qui s'étend sensiblement dans le sens longitudinal du forage et servant à l'introduction d'un fluide sous pression pour l'expansion au moins partielle de la périphérie extérieure de cet élément expansible (3, 4), et/ou ces tiges de forage sont raccordées à au moins un élément expansible (3, 4), présentant au moins une cavité qui s'étend sensiblement dans le sens longitudinal du forage et servant à l'introduction d'un fluide sous pression pour l'expansion de la périphérie extérieure dudit élément. On obtient ainsi, avec une construction simplifiée, un ancrage fiable par l'expansion desdits éléments expansibles (3, 4) dans les sens périphérique et longitudinal dudit dispositif.
