Abstract: The invention relates to a method of drilling ground along a drilling direction, the method comprising: providing at least first and second drill tubes (40, 42); providing an articulated and motorized manipulator arm (12) having a gripper member (30); using the gripper member (30) to take hold of the first drill tube (40); moving the gripper member in the drilling direction so as to drive the first drill tube into the ground, the gripper member releasing the first drill tube; then taking hold of the second drill tube and fastening the second drill tube to the first drill tube; and moving the gripper member so as to drive the first and second drill tubes into the ground.

Abstract: A drilling machine (10) for making an excavation in ground (S) in a vertical drilling direction (F). The drilling machine (10) includes: a support (12) having a longitudinal direction (L); a drilling module (14) provided with cutter members (16), the drilling module being movable in translation relative to the support; and a movement device arranged between the support and the drilling module in order to move the drilling module (14) relative to the support along the longitudinal direction of the support. The machine is characterized by the fact that the movement device includes a damper (70) for damping the vibration generated by the drilling module while drilling.

Abstract: A drilling machine for drilling ground in a vertical direction, the machine including: an anchor module having front and rear faces, the anchor module including an anchor device having front and rear anchor pads that are deployable in a deployment direction, to bear against walls of the excavation to hold the anchor module stationary in the ground. The anchor module further includes: a frame carrying the front and rear anchor pads, the frame supporting the drilling module; and an actuator device to which the front and rear anchor pads are fastened, the actuator device being movable relative to the frame in a movement direction that extends transversely to the longitudinal direction; whereby the assembly constituted by the front anchor pad, the rear anchor pad, and the actuator device is movable in the movement direction relative to the frame and the drilling module.

Abstract: A drilling machine (10) for making an excavation in ground in a drilling direction that is substantially vertical, the drilling machine including: an anchor module (22) having at least one anchor element for preventing the anchor module from moving relative to the walls of the excavation in the drilling direction, the anchor module having a longitudinal direction that is substantially vertical; a drilling module (12) provided with cutter members, the drilling module being movable in translation relative to the anchor module in the drilling direction; and a movement device (50) arranged between the anchor module and the drilling module in order to move the drilling module in translation relative to the anchor module in the drilling direction. The machine is suspended from a lift cable (70) that is fastened to the drilling module (12).

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.
