 mittels der Seile oder dgl. k hochgezogen, die Klappen e verlieren ihren Halt, öffnen sich und der Erdkern fällt aus dem Kernrohr heraus. Die Klappen e können übrigens während des Herausziehens des Kernrohres auch durch andere Hilfsmittel in ihrer Lage gesichert werden. 



   Wenn das Kernrohr aus dem Mantelrohr herausgeholt wird, kann es vorkommen, dass eine geringe Menge lockerer Grundkies oder dgl. auf dem Boden des Pfahlloches liegen bleibt. 



  Zweckmässig wird dieser Kies niedergestampft, so dass ein fester Boden im Pfahlloch entsteht. 



   Bei allen Ausführungsformen des Treibrohres wird das Mantelrohr in bekannter Weise mit Beton gefüllt und mit fortschreitender Füllung nach und nach aus dem Erdreich hochgezogen. 



   Die jeweils eingefüllte Betonschicht kann, wenn erforderlich, auch besonders gerammt werden. Man kann das Mantelrohr übrigens auch erst nach völliger Fertigstellung des Pfahles herausziehen. 



   PATENT-ANSPRÜCHE :
1. Treibrohr für   Betonpfähle,   dadurch gekennzeichnet, dass das unten offene, eingezogene, als Treibkopf dienende Ende des Kernrohres aus zwei oder mehr Klappen besteht, die beim Eintreiben feststellbar und nach dem Ausziehen des Treibrohres zur Entfernung des Kernes wieder lösbar sind.

 pulled up by means of ropes or the like. k, the flaps e lose their hold, open and the earth's core falls out of the core tube. The flaps e can also be secured in their position by other aids while the core tube is being pulled out.



   When the core pipe is taken out of the jacket pipe, it can happen that a small amount of loose ground gravel or the like remains on the bottom of the pile hole.



  This gravel is expediently tamped down so that solid soil is created in the pile hole.



   In all embodiments of the propulsion pipe, the casing pipe is filled with concrete in a known manner and gradually pulled up out of the ground as the filling progresses.



   The concrete layer filled in each case can, if necessary, also be specially rammed. Incidentally, you can only pull out the jacket pipe after the pile has been completed.



   PATENT CLAIMS:
1. Propulsion pipe for concrete piles, characterized in that the downwardly open, retracted end of the core pipe serving as a propulsion head consists of two or more flaps which can be determined when driving and can be released again after pulling out the propulsion pipe to remove the core.

Claims (1)

2. Treibrohr nach Anspruch 1, dadurch gekennzeichnet, dass die einzelnen drehbar angelenkten Klappen, die die Spitze bilden, in der Schlusslage durch einen auf dem Kernrohr verschiebbaren Ring gehalten sind, der sich gegen Ansätze der Klappen stützt. 2. Propulsion tube according to claim 1, characterized in that the individual rotatably hinged flaps which form the tip are held in the final position by a ring which is displaceable on the core tube and which is supported against approaches of the flaps.
