Abstract (en)

[origin: EP0299952A1] In a process for driving a tunnel with a shield tunnelling machine, in which the excavation space is sealed off from the shield structure (1) and is put under higher pressure relative to the space inside the shield structure (1), the pressure in the excavation space is transmitted directly to the material in the excavation space via a displaceable and pivotable sealing pressure bell (4), the pressure bell (4) being pressed against the material in the excavation space by means of an adjustable and controllable drive. <IMAGE>
