Drilling machine

Abstract

The invention relates to a drilling machine (10) for making an excavation in ground in a drilling direction, said drilling machine comprising: an anchor module (12) having an anchor device for preventing the anchor module from moving in the drilling direction relative to the ground by bearing against one of the walls of the excavation; a drilling module (20) provided with cutter members connected to the anchor module while being movable in translation relative to the anchor module; and movement means (35) for moving the cutter members in translation relative to the anchor module. The drilling module is also hinged relative to the anchor module, and the drilling machine comprises first path correction means (40) for causing the drilling module to pivot relative to the anchor module about a pivot axis (X) perpendicular to the drilling direction.
