摘要:
The invention relates to a cleaning device for the dry cleaning of a tunnel, comprising a feeding device for feeding a flow of air to a surface being cleaned, wherein the feeding device has an exit opening, through which the flow of air emerges from the feeding device, and a removal device comprising at least one removal pipe with a free end with an opening for suctioning away direct or trash from the surface with the opening of the free end in a first direction. The feeding device is arranged such that the flow of air from the exit opening emerges from the feeding device in a second direction toward the opening of the free end of the removal pipe and impinges on the surface. The first direction is oriented at an angle between 45° and 80° to the second direction.
