Description

Rammrohr zur Herstellung von Pfählen Es ist bekannt, Pfähle herzustellen, indem ein Rammrohr mit einem Innenrohr eingerammt, das Innenrohr mit dem Erdkern herausgehoben und schließlich das Rohr unter gleichzeitigem Betonieren gezogen wird. Das Herausheben des Innenrohres mit dem Erdkern setzt voraus, daß dasselbe unten verschlossen wird. Für dieses Verschließen des Innenrohres gibt es verschiedene Vorrichtungen, die jedoch zumeist umständlich, schwierig zu handhaben und unzureichend sind. Die Erfindung zeigt .eine Vorrichtung, nach welcher der Abschluß des Innenrohres einfach und durchaus zuverlässig ermöglicht wird. Die Erfindung besteht darin, daß dex Verschluß des Innenrohres durch an seinem unteren Ende befindliche Zungen gebildet wird, die unter der Wirkung leichter Rammschläge auf das obere Ende des Innenrohres durch schräg gerichtete Flächen des Rammrohres abgelenkt werden und sich zusammenschließen.Driving pipe for the production of piles It is known to produce piles, by ramming a ramming pipe with an inner pipe, the inner pipe with the earth's core lifted out and finally the pipe is pulled while concreting at the same time. The lifting out of the inner tube with the earth's core assumes that the same is below is closed. There are different ways of closing the inner tube Devices that are usually cumbersome, difficult to use and inadequate are. The invention shows .ein a device according to which the closure of the inner tube is made possible simply and reliably. The invention consists in that dex closure of the inner tube formed by tongues located at its lower end which under the effect of light ramming hits the upper end of the inner tube be deflected by inclined surfaces of the ram pipe and join together.

In den Abb. i bis q. ist die Erfindung in zwei Ausführungsbeispielen dargestellt. Abb. i zeigt den unteren Teil des ,eingerammten Rohres a mit dem Innenrohr b. Dias Innenrohr b, das während des Rammens an seinem oberen Ende am Rohr a festgemacht ist, endigt unten in den Zungen c. Die Spitzten dieser Zungen c berühren eine über der Schneidecl des Rohres a angeordnete, nach unten und inneu geneigte kegelförmige Fläche e. Wird das Innenrohr b oben freligemacht und mit leichten Rammschlägen geschlagen, so gleiten die Zungen c über die Schrägflächee und biegen sich zu einem geschlossenen kegelförmigen Boden zusammen. wie .dies in Abb. 2 dargestellt ist. Nun -,wird das Innenrohr b mit dem Erdkern herausgehoben und das Rohra unter gleichzeitigem Betonieren gezogen. Das Innenrohr b wird sodann vom Erdkern befreit, und es werden die Zungen c wieder geradegebogen, worauf es wieder verwendungsbereit ist.In Figs. I to q. the invention is shown in two embodiments. Fig. I shows the lower part of the rammed pipe a with the inner pipe b. The inner tube b, which is fastened at its upper end to the tube a during ramming, ends at the bottom in the tongues c. The pointed tips of these tongues c touch a conical surface e which is arranged above the cutting edge of the tube a and inclines downwards and inwards. If the inner tube b is opened at the top and hit with light ramming strokes, the tongues c slide over the inclined surface and bend together to form a closed, conical bottom. as shown in Fig. 2. Now - the inner pipe b with the earth's core is lifted out and the pipe a is pulled while concreting at the same time. The inner tube b is then freed from the earth's core, and the tongues c are straightened again, whereupon it is ready for use again.

Die Abb. 3 und 4. zergen ein Stahlbetonrohr f mit Stahlschneiden d. Die Schrägflächen e sind hier in die Stahlschneiden d eingeschnitten. In Abb.3 ist der bereits geschlossene Zun enboden dargestellt. Nach dem Herausheben des Innenrohres b mit dem Erdkern verbleibt das Stahlbetonrohr f im Erdboden und wird mit Betan h gefüllt, wie dies in Abb. 4. zur Darstellung gebracht ist.Figs. 3 and 4. zoom a reinforced concrete pipe f with steel cutting edges d. The inclined surfaces e are cut into the steel cutting edges d here. In Fig. 3 the already closed bottom is shown. After lifting out the inner pipe b with the earth core, the reinforced concrete pipe f remains in the ground and is filled with betane h, as shown in Fig. 4.
