Abstract: The present invention provides a device providing a combined boring and placement system for jacket tubes (5), which after introduction into a borehole, for the creation of a drainage system or a pipe roof or an anchoring or a tubular pile, remain in the rock mass and which, when creating the borehole, with an extension piece (4) of a drill rod assembly (2), wherein the extension piece (4) is fitted with a non-recoverable drill bit (6) which for this purpose can be partially or fully detached from the extension piece (4), wherein the drill bit(6) is connected with the assigned extension piece(4) of the drill rod assembly(2) via a locking element (20) that secures it against rotation, which to this end is arranged in a cage (21) formed by the drill bit (6), extension piece(4) and jacket tube(5) and which can be released by the jacket tube (5) covering the cage (21).

Abstract: For the purpose of producing boreholes (2) in the combined drilling and setting process, a tube spile (4), which subsequently remains in the borehole (2), is driven into the latter via a coupling sleeve (6). Said coupling sleeve (6) is constructed as a combined thrusting, striking and ejecting adapter (10), and therefore ensures both the propulsion of the tube spile and the transmission of the power of the drilling machine to the drill rod (5) and thereby the drill bit (3). Said drill bit (3) is secured on the drill rod (5), or rather its front end (37), via an axial fixing system (55) against unintended detachment.
