Abstract

The head has an external ferrule (20) including a flared portion (22) and a cylindrical portion (24), and mobile adjusting pads (44c, 44d) presenting a sliding face sliding along an external face of the flared portion of the ferrule and a contact face (46) in relation to an internal wall of a tunnel. A jack (50) moves each pad between an inactive position and a set of active positions. The contact face of the pad is completely placed inside a cylinder of diameter (Do) in the inactive position. A part of the contact face of the pad is at an exterior of the cylinder in the active positions. An independent claim is also included for a tunnel construction equipment comprising a drilling machine.
