  • the passage openings of the cladding tube along the axial generatrix of the cladding tube are formed and essentially in the circumferential direction in a plane normal to the longitudinal axis of the Cladding tube. This leaves them in the axial direction Areas on the circumference of the cladding tube in which none Through openings are provided so that the cladding tube certainly the tensile stresses that act on it can accommodate small material thicknesses if necessary.
  • the cladding tube on its surface facing the filter tube is corrugated or is formed with rib-like elevations on which the filter tube over at least part of its circumference is supported, so that with a correspondingly stiff training the cladding tube at the same time secure support of the Filter tube is achievable on the outer circumference of the cladding tube.
  • a sealing element on the outer circumference of the cladding tube is provided and that adjacent to the sealing element on the End facing away from the filter tube in the cladding tube at least one outlet opening to apply a backfill, in particular a hardening suspension is provided.
  • sealing element which in particular after deployment the filling compound, especially a hardening compound Suspension, such as concrete or the like, sealing enables the borehole to face the surrounding rock, will not only be the one intended for drainage Exactly defined distance or length of the borehole, but it is also prevented by such sealing that any fluid located in the area of the drill bit spreads along the outside of the cladding tube in the borehole and for example for rinsing or an undesirable increase in the dimensions of the borehole leads, such as when water occurs with an anchor to be placed in a roof would be where the borehole mouth sloped down runs and thus fluid present in the rock outside of the cladding tube could flow out.
  • the training is for a correspondingly simple sealing preferably taken so that the sealing element of a Cladding tube surrounding in a ring shape, lip-like or tongue-like Plastic element is formed, which is applied is expandable with the backfill, in this context it is further preferred that the sealing element with a hardness of 80 to 100 Shore, in particular about 90 shore. That results while maintaining an appropriate mechanical Strength or resistance of the sealing element also a corresponding elasticity, which in the case of insertion a proper expansion and thereby the sealing element against the wall of the manufactured Drill hole can be achieved.
  • the invention preferably suggested that the sealing element in the area is subsequently provided to the filter tube, whereby it through the sealing element and subsequent insertion a filling compound succeeds, then to the filter tube a corresponding sealing effect and anchoring one To achieve lining forming cladding tube. if the Position of the soil or rock layer to be drained is not exactly known, a correspondingly larger distance between the end of the filter tube and the sealing element be provided.
