KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Den Gegenstand vorliegender Erfindung bildet ein Vortreibrohr zur Herstellung von Gründungskörpern aus Zementmörtel, und zwar besteht das Neue der Erfindung darin, daß das Vortreibrohr beim Abteufen eine vollständig geschlossene Wandung hat, die aber durch Fräsung an bestimmten Stellen derart geschwächt ist, daß das Rohr bei Einführung des Zementmörtels unter hohemThe subject of the present invention forms a propulsion pipe for the production of Foundation bodies made of cement mortar, namely the novelty of the invention is that the propulsion pipe has a completely closed wall when sinking, which but is so weakened by milling at certain points that the pipe when introduced of cement mortar under high ίο Druck an diesen Stellen platzt und dem Mörtel den Austritt in das umgebende Erdreich gestattet.ίο Pressure bursts at these points and the mortar escapes into the surrounding soil allowed. Fig. ι zeigt ein derartiges Vortreibrohr im Längsschnitt. Fig. 2 bis 5 veranschauliehen verschiedene Formen der eingefrästen Rillen.Fig. Ι shows such a propulsion pipe in longitudinal section. Figures 2 through 5 illustrate different shapes of the milled grooves. ■ Das Rohr wird entweder durch Einrammen oder Bohren abgeteuft, wobei die noch geschlossene Wand das Eindringen von Erd-■ The pipe is sunk either by ramming or drilling, with the still closed Wall of the ingress of earth ao massen verhindert. Hierauf wird dünnflüssiger Zementmörtel unter hohem Druck in das Rohr eingepreßt, der schließlich das Rohr an den geschwächten Stellen zum Platzen bringt, wobei die eingefrästen Rillen aufschlitzen, sich zu Längs- und Querrissen erweitern und die Lappen α (Fig. 2 bis 5) sich nach außen umkrempeln, so daß dem Zementmörtel große Öffnungen zum Austritt ins Erdreich freigegeben werden.ao masses prevented. Then thin cement mortar is pressed into the pipe under high pressure, which finally causes the pipe to burst at the weakened points, the milled grooves slit open, expand into longitudinal and transverse cracks and the tabs α (Fig. 2 to 5) follow Turn the outside inside out so that the cement mortar has large openings to escape into the ground.
