ABSTRACT:
Tunnel-driving apparatus has a drive shield which can be composed of a series of planks arranged side-by-side around the tunnel and supported by a frame. The drive shield is advanced to penetrate the working face by operating hydraulic rams. To control and guide the shield and to inhibit rotary motion thereof a drifting cutter is positioned radially externally of the drive shield to cut a channel in the wall and preferably in the floor of the tunnel. In the latter case the channel can also be useful for drainage purposes. The drifting cutter is of elongate form guided for shifting parallel to the tunnel axis in advance of the drive shield. The axis of the cutter can be adjusted slightly by pivoting, for example, to control the guidance imparted by the drifting cutter.
