Definitions

  • the present invention relates to a cladding tube for a device for drilling holes and forming a Anchoring in soil or rock material, with the cladding tube with a drill pipe and / or a drill bit or a hammer drill is coupled and with its scope a plurality of through openings is formed as well after completion of the borehole or after insertion an anchor can be filled with a curable suspension is.
  • Devices for drilling, in particular for striking or Rotary impact drilling, and subsequent lining of holes in soil or rock material are in different Embodiments known. Hiebei will if necessary long hole or hole formed with the help of a drill bit, which on a drill pipe is stored, with a striking and / or rotating movement of the borehole is formed. To break in of material in which there may be a to avoid long length extending and / or post hole Completion of the drill liner is available To be able to pose, it was suggested, for example, to use a cladding tube surrounding the drill pipe, which is introduced during the drilling process.
  • an anchor After completion of the hole, for example, in an anchor is inserted into the cladding tube or the drill pipe find immediate use as an anchor and a rapidly setting suspension to solidify the surrounding Material are introduced.
  • a device with a cladding tube of the aforementioned can be found, for example, in WO 98/21439, in which a method and device for drilling and lining is revealed by holes.
  • surrounding cladding tube becomes an annular space between the cladding tube and the outer circumference of the drill pipe provided, for example in the area immediately adjacent to the drill bit at least one passage opening is essentially completely walled Cladding tube is provided, via which degraded Material if necessary from the borehole to be produced removed and a hardenable suspension for anchoring can be spread into the surrounding material.
  • the present invention now aims to provide a cladding tube to create the type mentioned, in addition to a quick and easy lining of the borehole simultaneous introduction of a cladding tube later secure anchoring or additional reinforcement in one Cladding tube to be inserted or use as an anchor finding drill pipe when introducing a curable Suspension, which is at least partially in the Borehole surrounding material is deployed with more reliable Anchoring the cladding tube can be achieved.
  • the cladding tube according to the invention essentially characterized in that the cladding tube at least one with evenly distributed passage openings provided expanded metal element is formed, which at its ends connecting elements, in particular sleeves, for connection to the drill bit and / or others Has cladding tube elements.
  • Cladding tube formed from at least one expanded metal element is which with a variety of evenly over the circumference of distributed through openings is successful safe, large-scale application of the curable Suspension in the surrounding material after completion of the borehole for setting the anchor, so that a corresponding one secure anchoring of the anchor and the cladding tube is achievable.
  • the Cladding tube ensured from at least one expanded metal element, that the cladding tube is not a perfectly flat, has a smooth outer surface so that after insertion the curable suspension due to the inherent surface design of the expanded metal element or the inherent unevenness the anchoring effect of the surfaces of the expanded metal element in the surrounding material after curing the suspension is increased accordingly.
  • the passage openings of the expanded metal element essentially rhomboid or diamond-shaped Have contours.
  • Such rhomboid or diamond-shaped Contours of the passage openings will be above also ensured during the drilling process that the Through openings not of mined material, which usually an essentially rounded or spherical one Form, completely misplaced and blocked become.
  • the expanded metal element a has a lattice or wire mesh-like structure, whereby a correspondingly large, free passage area the one remaining between the individual passage openings Material cross section results in great elasticity when inserting while achieving an increased Reinforcement and anchoring effect after grouting and Curing of the suspension results.
  • the cladding tube is constructed in multiple layers, wherein between in radial direction on the inner and outer surfaces arranged, formed with through openings expanded metal elements a plastic tube is provided.
  • the connecting elements formed by sleeves a graded or with offset areas Have formed contour on which the inside and external expanded metal elements and the intermediate Plastic pipe can be fixed.
  • Fig. 1 is schematically 1 with a drill bit for training designated a borehole, the outer contour with 2 is indicated, wherein for driving the drill bit 1 is a schematic with 3 indicated drill pipe is used.
  • a cladding tube 6 is provided, the cladding tube 6, such as this can be seen particularly clearly from FIG. 2 Expanded metal elements is formed, which at their end regions for connection to the drill bit 1 or the impact shoe 5 as well as with neighboring cladding tube elements 6 each are formed with sleeve elements 7 and 8.
  • the sleeve elements 7, 8 can be used to achieve a corresponding one Plug or screw connection to be formed especially with large dimensions of a borehole corresponding extension of the cladding tube 6 similar to the extension to enable the drill pipe 3.
  • Such a cladding tube or expanded metal element 6 is hiebei clearly shown in Fig. 2, which can be seen is that the evenly distributed over the circumference Through openings of the expanded metal element formed cladding tube 6 essentially each rhomboid or diamond-shaped contours 9, so that overall for the surface of the cladding tube 6 a grid or mesh-like structure results.
  • FIG. 3 is a partial section through on an enlarged scale a modified embodiment of a schematically with 10 indicated cladding tube shown, the multilayer Cladding tube 10 from an external, again with a Large number of perforated expanded metal elements 11, an inside, provided with openings Expanded metal element 12 and an intermediate plastic tube or element 13 is formed.
  • the expanded metal elements 11 and 12 in turn have an education or Condition similar to that shown in Figs. 1 and 2 Expanded metal element 6 with a variety of rhomboid or diamond-shaped passage openings 9.
  • the intermediate plastic tube 13 with a reduced Number of openings formed, in Fig.
  • one of the openings 14 is indicated, which in the sense a valve effect a passage of subsequently to be applied Suspension only in the direction indicated by arrow 15 indicated direction allows. It is thus in the Fig. 3 illustrated embodiment ensures that after introduction of the suspension to form an anchor no moisture from the surrounding material or no water towards the drill string 3 or one penetrate anchor to be arranged instead of the drill pipe 3 can, so that a corrosion effect is avoided and such anchors, which have also been used for many years Well can remain, can be produced.
  • FIG. 3 10 finds a modified design of a sleeve 16 with stepped areas 17 use to the definition of the individual layers or elements 11, 12 and 13 to form the sandwich-like structure of the cladding tube 10 to enable.
