  Entlastetes Tiefbohrgestänge für Spülbohrung. 



   Bei der Herstellung von Bohrlöchern mittels Spülbohrung kann der Auftrieb des in das   Spülwasser   getauchten Bohrgestänges vorteilhafterweise dazu ausgenützt worden, um die zur Bewegung des Gestänges bei grossen Tiefen erforderlichen Kräfte bedeutend zu vorringern. Es geschieht dies in bereits bekannt gewordener Weise dadurch, dass das Bohr-   gestänge   mittels zwischen äusseren und inneren Rohren vorgesehener wasserdicht abgeschlossener Hohlräume ganz oder teilweise entlastet wird. 



   Gegenstand der vorliegenden Erfindung ist nun die Ausbildung der Verbindungs-   muffen   der entlasteten Gestängeteile in der Art, dass nach dem ZusammenfÜgen zweier Gestängeteile innerhalb der Muffen ein   ringförmiger Raum verbleibt, welcher durch Löcher     beständig   mit   dem Aussenraum zusammenhängt.

   Durch   diese Einrichtung   soll gegenüber   einem Gestänge, bei welchem die Innen- und Ausseurohre ohne Unterbrechung von der

 den Dichtungsring G vorgesehen. Durch die Löcher der Muffe   M   kann jederzeit das auf-   steigende Spülwasser in   die Kammer E eintreten, so dass in derselben immer ein Wasserdruck vorhanden ist, welcher dem in gleicher Tiefe befindlichen aufsteigenden Spülwasser gleichkommt. Die Verbindungsstellen unterliegen daher, eine vollständige Entlastung der   Gestängetoilo   vorausgesetzt, nur einem Drucke, welcher durch die Rinfläche der   Abdichtnngs-,   eventuell   der Gewindeprojoktion bestimmt   ist.

  Relieved deep drill rods for flush drilling.



   When drilling boreholes by means of flushing drilling, the buoyancy of the drill rods immersed in the flushing water can advantageously be used to significantly reduce the forces required to move the rods at great depths. This is done in a manner that has already become known in that the load on the drill rod is completely or partially relieved by means of cavities which are watertight and which are provided between the outer and inner tubes.



   The subject of the present invention is the formation of the connecting sleeves of the relieved rod parts in such a way that after the joining of two rod parts within the sleeves an annular space remains, which is continuously connected to the outside space through holes.

   Through this device, compared to a linkage, in which the inner and outer pipes without interruption of the
 EMI1.1
 Avoided as much as possible, and pipes with a smaller wall thickness will suffice.
 EMI1.2
 
Each rod part, which consists of an outer tube R and an inner tube serving to supply the flushing water, has one another at its ends
 EMI1.3
 Flange with nut threads and an inner sealing flange between which an annular chamber jE 'is provided.



   At the level of chamber E, the outer flange is penetrated in several places.
 EMI1.4
 the sealing ring G is provided. The rising flushing water can enter the chamber E at any time through the holes in the sleeve M, so that there is always a water pressure in the same which is equal to the rising flushing water located at the same depth. The connection points are therefore only subject to a pressure, provided that the rod assembly is completely relieved, which is determined by the surface area of the sealing, possibly the thread projection.
