Abstract (en)
The method involves using an overpressure air curtain, which uses air as a cleaning medium. The curtain produces a turbulence that is immanent in a cleaning region by inclining air nozzles to support the overpressure air curtain. The curtain is varied corresponding to a suction power. The curtain avoids lateral spacing of air that is necessary for cleaning. Suction air is concentrated and sucked from a bottom in a loss free manner via the use of the air curtain. Blowing nozzles are integrated in a suction trap (2) in a mechanical, constructive and functional manner. An independent claim is also included for a device for cleaning the track bed structure and the tunnel wall.
