Apparatus for converting a tunneling machine by means of an intermediate station located between two tunnel sections.

摘要

Device for the displacement of a tunnelling machine and for transferring it across an intermediate station between two tunnel sections, characterised in that there are removable stringers (7) consisting of successive segments (18) and arranged in sets to form a rolling cradle, the last segments being engaged cantilevered within the outer casing (8) of the tunnelling machine, to serve as support for jacks (9) advancing this tunnelling machine, those parts of the stringers (7) located at the rear of the said tunnelling machine forming on top runways for carriages associated with the tunnelling machine, which, moreover, is supported by the outside of its casing.
