Abstract

A dry mixture of concrete and aggregates is mixed with water prior to bulk injection by tube or pipe to a structure. The mixing action of water to dry components is supplemented in a secondary mixing assembly which is a pipe (1) containing a rising V-shaped plane, translating through a saddle to a descending through a V-shaped plane.

Description

Ein wesentliches Problem beim Trockenspritzbetonverfahren ist u.a. das 100%ige Vermischen des trockenen Mischguts mit Wasser. Um dieses Problem zu lösen, gibt es zahlreiche Vorrichtungen, sowohl im Wasserdüsenbereich, als auch an anderen Stellen des Systems. Es ist jedoch nach wie vor ein Problem, trockenes Mischgut im Durchlaufmischen staubfrei mit Wasser zu vermischen. Es gibt bereits ein Umlenkkammermischrohr, wie in dem Gebrauchsmuster DE 201 06 434. U1 beschrieben. Dieses Umlenkkammermischrohr kann sich jedoch zusetzen.One of the main problems with the dry shotcrete process is the 100% mixing of the dry mix with water. To solve this problem, there are numerous devices, both in the water nozzle area and elsewhere in the system. However, it is still a problem to mix dry mix dust-free with water in continuous mixing. There is already a deflection chamber mixing tube, as in the utility model DE 201 06 434. U1 described. However, this deflection chamber mixing tube can become clogged.

Die Aufgabenstellung der Erfindung besteht darin, eine einfache, kostengünstige und baustellengerechte Lösung zu finden.The object of the invention is a simple, inexpensive and site-friendly solution to find.

Im Nachmischrohr trifft das mit Wasser benetzte Mischgut zunächst auf die Aufprallflächen (2.1) und (4.1) und wird von diesen auf die Reflexionsflächen (3.1) und (3.2) umgelenkt. Ein weiteres Umlenken erfolgt beim Auftreffen auf die Aufprallfläche (2.2) von wo aus das Mischgut weiter nach unten und vorne ins Rohr geblasen wird.In the post-mixing tube, the mixed material wetted with water first hits the impact surfaces ( 2.1 ) and ( 4.1 ) and is transferred from these to the reflective surfaces ( 3.1 ) and ( 3.2 ) redirected. Another deflection takes place when it hits the impact surface ( 2.2 ) from where the mix is blown further down and into the pipe at the front.

Durch diesen Umlenkprozess erfolgt ein intensives Vermischen des Mischguts mit Wasser, sodass die Staubbildung beim Austritt des Mischguts aus dem Rohr vernachlässigbar gering bzw. nicht vorhanden ist. Der Rückprall wird durch die gute Durchmischung des Mischguts mit Wasser ebenfalls wesentlich geringer.Through this redirection process an intensive mixing of the mix with water, so that the dust formation negligible when the mix emerges from the pipe low or nonexistent. The rebound is due to the good mixing the mix with water is also much lower.

Eine Ausführung des Nachmischrohres ist so ausgeführt, dass die Wasserdüsen für die Benetzung des Mischgutes im verlängerten, zuführenden Rohr angeordnet sind.One version of the post-mixing tube is executed so that the water jets for the Wetting of the mixed material in the extended afferent Pipe are arranged.
