Claims20
An angle-adjustable conveying apparatus for a tunnel boring machine (TBM), the apparatus comprising:
- a deck trailing the TBM;
- an endless bottom belt operatively associated with the deck and extending therefrom to a discharge end, wherein the bottom belt operatively associates with a deflection pulley just downstream of the deck so as to define a receiving belt portion of the bottom belt between the deck and the deflection pulley;
- and
- an endless cover belt operatively associated with the deck in such a way that the cover belt is urged against an upper surface of the bottom belt downstream of the deflection pulley;
- and
- two belt storage units disposed adjacent the discharge end, wherein each of the belts pays out from one of the two belt storage units, respectively, as the TBM forms a tunnel.

- and
- an endless cover belt operatively associated with the deck in such a way that the cover belt is urged against an upper surface of the bottom belt downstream of the deflection pulley;
- the deck comprising a loading station configured to transfer a product of the TBM to the receiving belt portion, wherein the deck provides a plurality of drive pulleys, at least one of the drive pulleys operatively associated with each said belt;
- and
- two belt storage units disposed adjacent the discharge end, wherein each of the belts pays out from one of the two belt storage units, respectively, as the TBM forms a tunnel.
