Description
Füllrohr für die Herstellung von Ortpfählen aus Beton Die Erfindung betrifft ein Verfahrnen zur Verdrängung des Grundwassers bei Herstellung von Ortpfählen aus Beton oder Eisenbeton mittels eines Füllrohres, das in einem Vortreibrohr lose geführt wird und in dem der Beton. gegen das Grundwasser durch einen lösbaren Boden abgeschlossen ist.Filling pipe for the production of cast-in-place piles from concrete The invention relates to a method for displacing the groundwater in the production of site posts made of concrete or reinforced concrete by means of a filling pipe, which is loosely in a driving pipe is performed and in which the concrete. against the groundwater through a removable soil is completed.
Gem;ä"ß der Erfindung soll. eine Ausgestaltung dieses Verfahrens durch eine besondere Ausbildung des Füllrohres erfolgen, indem der rechtwinklig umgebogene Randu des Füllrohres mit sich nach oben öffnenden Ventilen versehen wird, um so zu erreichen, daß eine Vermischung des Grundwassers mit dem Beton beim Ziehen des Füllrohres wirksam vermieden wird.According to the invention, an embodiment of this method is to be carried out a special design of the filling tube is made by the bent at right angles Randu of the filling tube is provided with upward-opening valves, so to achieve that a mixing of the groundwater with the concrete when pulling the Filling tube is effectively avoided.
In der Zeichnung ist die neue Ausbildung des Füllrohres veranschaulicht, und zwar zeigt die Abb. i den Bauzustand beim Absenken und die Abb. z den Bauzustand beim Hochziehen. des Füllrohres.In the drawing, the new design of the filling tube is illustrated, Fig. i shows the state of construction when lowering and Fig. z shows the state of construction when pulling up. of the filling pipe.
Die in der Umbördelung u am Fuße des Füllrohres angebrachten Ventile gestatten den Durchtritt des Wassers nach oben, nicht aber nach unten. Dieses kann z. B. dadurch geschehen, daß .die Umbör delung bis zur Innenwandung des Vortreibrohres reicht und Ausnehmungen oder Löcher erhält, die von oben durch Ventilklappen, einen gemeinsamen Ventilring o. dgl. geschlossen werden. Beim Einführen des Betons in das Füllrohr strömt das Wasser durch die sich öffnenden Ventile nach oben ab (Abb. i). Beim Ziehen des Füllrohres schließen sich die Ventile (Abb. z) und halten derart das zwischen den Wandungen der beiden Rohre stehende Wasser von dem Beton fern.The valves in the flange u at the foot of the filling pipe allow the water to pass upwards, but not downwards. This can z. B. happen that .the Umbör delung up to the inner wall of the propulsion pipe is enough and recesses or holes received from above through valve flaps, a common valve ring o. The like. Be closed. When inserting the concrete into the filling pipe flows the water upwards through the opening valves (Fig. i). When the filling tube is pulled, the valves (Fig. Z) close and hold in this way the water standing between the walls of the two pipes away from the concrete.
