Description

Vorrichtung zum Einleiten der Ausziehbewegung bei unmittelbar in den Boden eingesenkten Pfählen oder bei Kernpfählen für Senkrohre Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Einleiten der Ausziehbewegung bei unmittelbar in den Boden eingesenkten Pfählen oder bei Kernpfählen für Senkrohre.Device for initiating the pull-out movement at directly in the Soil countersunk piles or core piles for countersunk pipes The present invention refers to a device for initiating the pull-out movement at directly Piles sunk into the ground or, in the case of core piles, for countersunk pipes.

Die Erfindung besteht darin, daß zwischen Pfahlschuh und Pfahl eine hydraulische Presse eingeschaltet ist, so daß durch Einführung eines Druckmittels das Anheben des Pfahles erfolgt.The invention consists in that between the pole shoe and pole a hydraulic press is switched on, so that by introducing a pressure medium the pile is raised.

Zweckmäßig ist hierbei der Pfahlschuh zu dem einen Teil einer hydraulischen Presse ausgebildet, der mit dem den entsprechenden anderen Teil bildenden Pfahl zusammenwirkt. Durch diese Ausgestaltung wird, abgesehen von der leichten Bedienung, die Ausübung größerer Kräfte, Anwendung verschiedener Albersetzung und die Verwendung maschineller Energie ermöglicht.The pole shoe is useful for one part of a hydraulic one Press formed, which with the corresponding other part forming pile cooperates. With this design, apart from the ease of use, the exercise of greater powers, the application of various translations and the use machine energy enables.

Die Verwendung von Preßwasser zum Lockern von Pfählen ist bereits vorgeschlagen worden, doch wurde hierbei so vorgegangen, daß das Preßwasser zwischen Kern und Mantelrohr eingeführt wurde und lediglich durch Erweiterung des letzteren eine Art Ausschrauben des Kernes erleichterte. Im vorliegenden Falle handelt es sich jedoch um die unmittelbare Erzeugung eines Axialschubes, dem der Pfahlschuh als Wi-derlager dient.The use of press water to loosen piles is already has been proposed, but the procedure was so that the press water between Core and jacket tube was introduced and only by expanding the latter a kind of unscrewing the core made it easier. In the present case it is However, it is about the immediate generation of axial thrust, which the pile shoe serves as a resistance camp.

In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsforrn im Längsschnitt veranschaulicht.In the drawing, the subject matter of the invention is shown in an exemplary embodiment illustrated in longitudinal section.

Der Pfahl bzw. Pfahlkern i trägt an seinem Ende einen Preßzylinder z, der durch eine den Pfahl durchsetzende Leitung 3 mit einer Druckflüssigkeitspumpe in Verbindung steht. Der Pfahlschuh q. bildet den Preßkolben. Wird Druckflüssigkeit eingepumpt, so wird der Pfahl i von dem Schuh d. abgehoben.The pile or pile core i carries a press cylinder at its end z, through a line 3 penetrating the pile with a hydraulic fluid pump communicates. The pole shoe q. forms the plunger. Becomes hydraulic fluid pumped in, the post i is driven by the shoe d. picked up.
