Abstract (en)
[origin: DE102012219134A1] The method involves opening an aperture (22) of a discharging device (18) in a discharging direction in open tunneling or earth pressure-supported tunneling. Another aperture (28) is closed and arranged downstream in the discharging direction of the former aperture. The former aperture is closed and the latter aperture is opened in a fluid-assisted tunneling. The closed former aperture and opened latter aperture are conveyed from a rinsing chamber (34). A closure (23) is arranged between conveying screws (19, 37) that are located at a distance from each other. An independent claim is also included for a device for discharging an excavated material with a tunnel boring machine.
