Apparatus and Method for Large Tunnel Excavation in Soft and Incompetent Rock or Ground
The invention provides a tunneling machine which, simultaneously with removal of the tunnel face, installs an initial supporting liner on the excavation walls. It provides a machine and method capable of an improved economical advance rate of excavation in loose, wet or unconsolidated earth by use of melt-consolidation techniques in which a tunnel defining kerf is melted into the tunnel face and the melt is simultaneously applied to the excavation bore to form an initial supporting liner.
