Abstract
(DE)
Aufbringen von Spritzbeton (S) mittels einer Spritzbetondüse (14) mit zugeordneter Mischeinrichtung (18) zum Zudosieren von Erstarrungsbeschleuniger (24) zu mittels der Spritzbetondüse (14) auszubringendem Spritzbeton (S), wobei eine sensorgesteuerte Zudosierung des Erstarrungsbeschleunigers (24) in Abhängigkeit eines äußeren Parameters vorgesehen ist.
(EN)
Applying sprayed concrete (S) by means of a sprayed concrete nozzle (14) with an associated mixing device (18) for metering setting accelerator (24) to the sprayed concrete (S) to be applied by means of the sprayed concrete nozzle (14), the metering of the setting accelerator (24) being controlled by sensors, depending on an external parameter.
