Abstract (en)

A tunneling plant to perform an excavation, a mucking and a lining from a face side, which plant comprises a transfer platform for sheets (7), a centering (8) and a continuous belt conveyor (5) to convey muck. The continuous belt conveyor has two sections, a tunnel supporting section (a support section (1a) and a lining section (1c)) where the conveyor is supported from a tunnel side in front of a transfer platform for sheets part and in the rear of a centering part, and a tunnel non-supporting section (waterproof sheet section (1b)) where the conveyor is not supported from the tunnel side, whereby the continuous belt conveyor passes through the transfer platform for sheets and the centering part. When a continuous belt conveyor is used to convey muck, the lining can be performed at the same time as the excavation (mucking). This leads to a rapid construction, remarkable improvement of safety and a clean working environment in the tunnel. <IMAGE>
