Definitions

  • the present invention relates to a pipe screen for shielding a tunnel construction against rockfall, with a plurality of cladding tubes, which are arranged on the profile circumference of the tunnel structure and extend substantially along the tunnel structure through the mountains, wherein at least one cladding tube of at least two interconnected Hüllrohrabêten each having a threadless, provided with an inner cone socket end and a threadless, provided with an outer cone spigot end and wherein the Hüllrohrab mustarde are connected by the fact that the spigot end of the first Hüllrohrabites is inserted into the socket end of the second Hüllrohrabites.
  • the cladding tubes are introduced into the mountains using a double-tube drilling method - impact or rotary impact drilling.
  • the inner linkage and possibly also the drill bit are removed, but the cladding tube remains in the borehole and cement is filled.
  • Such a double-tube drilling method is described in AT 407895 B.
  • Fig. 1 Drill mount during pipe screen drilling (prior art).
  • Screwed pipe connections are widely used, in which the cladding tubes each have an inner or an outer thread at the ends. The internal thread is screwed into the external thread. Disadvantage of these screwed ducts is that they can dissolve when the drill bit has to be rotated backwards. This is the case when the drill bit gets stuck. Already partially loosened screw connections are no longer able to transmit the required bending moments between the cladding tube sections, so that the carrying capacity of the tube screen is not given at this point. As a rule, then you have to re-drill.
  • DE 10 2004 020 065 B3 discloses a tube connection suitable for pipe screen drilling, in which the casing tube sections each have a spigot end and a socket end.
  • the outer conical end of the pin is inserted into the inner conical sleeve end, so that a frictional connection between the Hüllrohrabroughen without additional coupling elements.
  • this solution provides a plastic deformation of the wall of the socket end in such a way that inwardly pressed material engages in provided grooves of the pin end and thus forms an additional, non-releasable positive connection with the necessary strength.
  • Disadvantage of this solution is the inherent radial compression of the material of the socket end.
  • the present invention is therefore the object of developing a pipe shield so that its individual Hüllrohrabitese can be permanently connected without the help of additional coupling elements and without an additional, expansive pressing device.
  • the spigot end is provided with at least one, radially projecting nose over the outer cone, that the spigot end is further provided on its outer side with at least one peg groove projecting radially behind the outer cone, wherein the outer cone extends exclusively between the pin and the nose, and that the sleeve end is provided with a sleeve groove projecting radially behind the inner cone into which the nose engages.
  • the cladding tubes are thus joined positively by a snap connection formed from nose and sleeve groove.
  • a plastic deformation of the sleeve material does not take place because the pin end thanks to the pin groove, which reduces the moment of resistance of the pin end deformed when pushed together only in the elastic region and finally engages with the nose resiliently in the socket groove. For this reason, no additional pressing device is needed.
  • the ducts can be added either with the already present on the drill mount hammer feed or alternatively with a specially provided for this linear cylinder.
  • Such a linear cylinder could extend along the drill carriage and would thus not protrude into the narrow, marked in Figure 1 with "A" working space.
  • the ducts of the pipe umbrella according to the invention are not only form-fitting joined via the latching in the sleeve groove nose, but also also non-positively via the nested cones.
  • the tension in the conical seat is favored by the fact that the outer cone extends only between pin groove and nose.
  • the pipe shield is thus ensured that the Hüllrohrabitese not solve each other even when reversing the drill bit and always transmit the necessary bending moment. Additional coupling elements are eliminated.
  • the present invention can be carried out in two variants, namely in the already described first variant according to claim 1, wherein the nose is located at the spigot end.

Abstract

L'invention concerne un écran tubulaire (1) destiné à protéger un tunnel (2) contre la chute de pierres, comportant une pluralité de tubes d'enveloppes (5) disposés sur la périphérie de profil du tunnel (2) et s'étendant essentiellement le long du tunnel (2) au travers de la roche (3). Au moins un tube d'enveloppe (5) est composé d'au moins deux sections de tubes d'enveloppe (7) connectées l'une à l'autre, présentant respectivement une extrémité de manchon non filetée (9) et une extrémité de tenon non filetée (8). Les sections de tubes d'enveloppe (7) sont connectées du fait que l'extrémité de tenon (8) de la première section de tube d'enveloppe (7) est enfichée dans l'extrémité de manchon (9) de la deuxième section de tube d'enveloppe (7). L'invention vise à améliorer l'écran tubulaire (1) de telle manière que ses sections de tubes d'enveloppe (7) peuvent être jointes de façon rapide et sûre sans dispositif de compression ou éléments de connexion supplémentaires. A cet effet, l'extrémité de tenon (8) est pourvue d'une saillie (12) et l'extrémité de manchon (9) est pourvue d'une rainure (14) dans laquelle s'encastre la saillie (12).
