Description

Verfahren zum Herstellen von Preßbetonkörpern. Die Erfindung betrifft ein Verfahren zum Herstellen von Preßbetonkörpern. Das Neue besteht darin, daß man das gasförmige oder flüssige Druckmittel bei stetem Wechseln ihrer Spannungen unmittelbar auf den herzustellenden Betonkörper einwirken l,äßt und die Spannungsänderungen durch stoßweises Öffnen und Schließen einer Ausblasevorrichtung hervorgerufen werden.Process for the production of pressed concrete bodies. The invention relates to a method for the production of pressed concrete bodies. The new thing is that one the gaseous or liquid pressure medium with constant changing of their voltages immediately to act on the concrete body to be produced, and the changes in tension caused by intermittent opening and closing of a blow-out device.

Beim Öffnen der Ausblasevorrichtung entweicht die Druckluft plötzlich, und ihre Spannung sinkt, während bei deren plötzlichen Schließung der Druck nicht nur die volle Höhe des Betriebsdruckes von z. B. 6 Atmosphären wieder erreicht, sondern infolge des Rückschlages stoßartig darüber hinaus, z. B. auf 2o Atmosphären, anwächst. Durch immer wiederholtes und rasch aufeinanderfolgendes Öffnen und Schließen der Ausblasevorrichtung wird also der frische Beton einer großen Anzahl starker und schneller Schläge ausgesetzt, immer wieder aufs Neue zusammen;gepreßt und auf diese Weise in seinem Gefüge verbessert.When the blow-out device is opened, the compressed air suddenly escapes, and its tension sinks, while when it suddenly closes the pressure does not only the full height of the operating pressure of z. B. 6 atmospheres reached again, but as a result of the setback abruptly beyond, z. B. on 2o atmospheres, grows. By repeatedly opening and closing in rapid succession Thus, with the blowing device, the fresh concrete of a large number becomes stronger and exposed to faster blows, again and again together; pressed and open this way improved in its structure.

Man kann dieses Verfahren besonders zum Herstellen von Preßbetonpfählen verwenden: hierbei wirken. die durch den steten Wechsel der Spannung des Druckmittels erzeugten Schläge nicht nur auf die im Bohrrohr anstehende flüssige Betonmasse., sondern durch diese hindurch auch auf die anstehenden Untergrundschichten, so daß infolgedessen der Beton die nachgiebigeren Schichten wertkräftiger zurückdrängt, als es durch ruhenden Luftdruck möglich ist. Die weitere Folge aber ist, daß ein solcher Pfahl auf das innigste in den Untergrund eingetrieben wird.One can use this method especially for the production of pressed concrete piles use: act here. caused by the constant change in the tension of the pressure medium generated impacts not only on the liquid concrete mass in the drill pipe., but through this also on the pending subsurface layers, so that as a result, the concrete pushes back the more pliable layers of greater value, than is possible with static air pressure. The further consequence is that a Such a post is driven deeply into the ground.
