Abstract

Zum Aufbringen von Spritzbeton auf Wandungen und bruchgefährdete Flächen werden Zuschläge sortierter Körnung, Zement, Bindemittel, Wasser und eventuell weitere den Beton verbessernde Zusatzstoffe und Zusatzmittel auf die zu sichernden Wandungen oder Flächen aufgeschleudert. Um einerseits ein unerträgliches Stauben beim Mischen der Betonkomponenten zu vermeiden und andererseits zu den benötigten Zeiten einen Beton guter Qualität und guter Halffähigkeit bereitstellen zu können, wird am Einsatzort unmittelbar vor dem Spritzen chargenweise Zementleim aus Zement und Wasser sowie eventuell aus weiteren den Zementleim verbessernden Stoffen hergestellt. Die Zuschläge werden getrennt bereitsgehalten. Der Zementleim wird zu einer Spritzdüse gefördet und aus dieser unter hohem Druck ejiziert unter Vermischung mit den getrennt durch Druckluft zugeführten Zuschlägen in der oder im Bereich der Spritzdüse. For applying shotcrete to walls and fragile ones Areas are aggregates of sorted grain, cement, binder, water and possibly other additives that improve the concrete and Additive to the walls or surfaces to be secured hurled. On the one hand an unbearable dusting when mixing the concrete components to avoid and on the other hand to the required Provide concrete of good quality and good semi-ability at times To be able to do this is carried out in batches immediately before spraying Cement glue from cement and water and possibly from other Made of cement paste improving substances. The surcharges will be already held separately. The cement paste becomes a spray nozzle pumped and ejected from this under high pressure with mixing with the supplements supplied separately by compressed air in or Area of the spray nozzle.
