Abstract

Die Erfindung betrifft ein Bohrgestänge, wie es zum Einbringen von Bohrungen ins Erdreich über lange Distanz, und vorzugsweise zum Einbringen von sogenannten Horizontalbohrungen verwendet wird, welches insbesondere beim Einsatz in Horizontalbohrmaschinen sowohl ein störungsfreies und schnelles Einbringen der Bohrung als auch ein zuverlässiges Einziehen der Rohrleitung ohne Beschädigung der Rohrleitung sicherstellt. Ein derartiges Bohrgestänge besteht aus einer mehrteiligen Bohrstange (20), einem Bohrkopf (21), einem Einzugskopf (1) zum Einziehen einer Rohrleitung (22) in das Bohrloch (23) und einer Spannbacke (35) zum Halten und Vorwärts- bzw. Rückwärtsschieben der Bohrstange und kennzeichnet sich dadurch, daß am Einzugskopf (1) am einen Ende ein Drehteil (5) zum Befestigen der einzuziehenden Rohrleitung drehbar, axial fest angeordnet ist, und am anderen Ende des Einzugskopfes das Ende der Bohrstange (20) axial verschiebbar, drehfest angeordnet ist.

The invention relates to a drill pipe as it is used to make holes in the ground over a long distance, and preferably for the introduction of so-called horizontal holes, which, particularly when used in horizontal drilling machines, both trouble-free and quick drilling of the hole and reliable drawing in of the pipeline without Ensures damage to the pipeline. Such a drill pipe consists of a multi-part drill rod (20), a drill head (21), a feed head (1) for pulling a pipeline (22) into the borehole (23) and a clamping jaw (35) for holding and pushing forward or backward the boring bar and is characterized in that on the feed head (1) at one end a rotating part (5) for fastening the pipeline to be pulled is rotatably, axially fixed, and at the other end of the feed head the end of the boring bar (20) is axially displaceable, rotatably is arranged.
