  Die nachfolgenden Gange finden ihren Weg frei. 



   Diejenigen Futter, welche bereits stark verschleisst sond, besitzen nicht mehr die Festigkeit, dem Druck des Werkzeuges zum Herausziehen des Futters zu widerstehen und werden zerdrückt, ohne dass der Rohrmantel beschädigt wird, auch wenn sie tiefer im Innern des Mantelrohres liegen. Der Zweck des Ausbaues dieser Futter, um sie durch neue ersetzen   zu können, ift   damit erreicht. 



   Zur Sicherstellung einer nicht nur groben, sondern ganz genauen und   vollständig   selbsttätigen Einstellung der Futter in ihrer Schwerpunktlage werden gemäss der'Erfindung ferner die aneinander stossenden Stirnseiten der Futter abgeschrägt. Wenn bei dem Einbau die einzelnen Futterrohre   aufeinandertressen, so müssen   notwendiger Weise die noch nicht in ihrer

   In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel erläutert. 



   Es stellt Fig. 1 einen Längsschnitt eines Rohres mit Rohrfutter und rigförmigen Leisten dar, Fig. 2 dergleichen mit   schraubengangförmig verlaufenden Leisten, wahrend Fig.   3 den   Querschnitt   hiezu in   vergrössertem     Massstahe xeigt.   



   Fig. 4 und 5 zeigen im   Längsschnitt   ein mit drei Einzelfuttern ausgeführtes Mantelrohr sowie die schrägen Flächen a bzw. b, in denen sich die Stirnseiten der Rohrfutter   aneinander-

 an   der Verwendungsstelle auch   im Dunkeln erfolgen, der Transport schwerer gefütterter Rohre fällt weg. Die beste Wirkung wird erzielt mit Futtern aus Eisen und überhaupt Materialien von hohem spezifischem Gewicht. Bei Spülversatzleitungen in Bergwerken,   wobe ! Rohre   von in der Regel 150 mm   Durchmesser und grösser verwendet werden,   ist die Wirkung einevorzügliche.

  The following corridors find their way free.



   Those chucks that are already heavily worn out no longer have the strength to withstand the pressure of the tool to pull out the chuck and are crushed without damaging the pipe jacket, even if they are deeper inside the jacket pipe. The purpose of expanding this lining in order to be able to replace it with new one is thus achieved.



   In order to ensure a not only coarse, but very precise and completely automatic setting of the chucks in their center of gravity, according to the invention, the abutting end faces of the chucks are also beveled. If the individual pipe liners press against one another during installation, they do not necessarily have to be in their

 important, because otherwise the eccentric clearances of the individual pipe chucks would be offset from one another in the direction of rotation and thus form externally close-fitting joints at which the movement of the pipe content would be inhibited and which, as a result of the cross-sectional improvement, reduce the performance and offer undesirable attack on the wear would.



   In the drawing, the invention is explained using an exemplary embodiment.



   It shows Fig. 1 a longitudinal section of a pipe with pipe liner and rig-shaped strips, Fig. 2 the same with helical strips, while Fig. 3 shows the cross-section to this enlarged scale.



   4 and 5 show, in longitudinal section, a casing pipe designed with three individual chucks and the inclined surfaces a and b, in which the end faces of the pipe chucks meet one another.

 at the point of use even in the dark, there is no need to transport heavily lined pipes The best effect is achieved with linings made of iron and generally materials with a high specific weight. For flushing offset lines in mines, wobe! Pipes with a diameter of 150 mm and larger are used, the effect is excellent.
