Definitions
- the present invention relates to the field of drilling in the ground, in particular to manufacture foundations, such as for example continuous screens consisting of juxtaposed concrete wall elements.
- the invention relates to a drilling machine for excavating a soil in a drilling direction, said excavation having walls and said drilling machine comprising:
- an anchoring module provided with at least one anchoring device for blocking the displacement in the drilling direction of the anchoring module relative to the ground by bearing on one of the walls of the excavation;
- a drilling module provided with cutting members, the cutting members being movable in translation relative to the anchoring module;
- displacement means for translational movement of the cutting members relative to the anchoring module.
- Such a machine is described in particular in document FR 2 806 112. It comprises anchoring means which make it possible to block the displacement in the vertical direction of drilling of the main frame with respect to the walls of the trench, and means for vertically push down on the milling assembly
- Such a machine makes it possible to exert a vertical thrust on the cutting members whose intensity is much greater than the weight of the frame, which makes it possible to drill in hard ground, such as for example the granite.
- a disadvantage of this machine is that the cutting members may tend to slide on hard ground portions, which may cause a deviation in the trajectory of the drilling machine, which is problematic, especially when making drilling at great depth.
- An object of the present invention is to overcome the aforementioned drawbacks by proposing a drilling machine for drilling hard terrain while controlling the drilling path.
- the drilling module is articulated with respect to the anchoring module and the drilling machine comprises at least first trajectory correction means configured to pivot, along a pivot axis transverse to the drilling direction, the drilling module with respect to the anchoring module.
- the drilling direction is substantially vertical, and at least non-horizontal.
- the drilling module is mounted in particular pivoting relative to the anchoring module.
- the pivoting of the drilling module relative to the anchoring module makes it possible to modify the position of the cutting members, and hence to correct the trajectory of the drilling machine.
- the first drilling path correction means are actuated while the anchoring device is actuated, that is to say while the anchor module is stowed in the ground.
- the anchoring module when it is desired to correct the trajectory of the drilling machine, the anchoring module is immobilized in the ground by actuating the anchoring device, and the drilling module is pivoted with respect to the anchoring module. by acting on the first path correction means, and acting on the displacement means to translate the drilling module in translation downwards relative to the anchoring module.
- the pivoting of the drilling module with respect to the anchoring module may take place before, after or concomitantly with the translational movement of the drilling module relative to the anchoring module. It is thus clear that the invention makes it possible to correct the direction of drilling accurately by anchoring the anchoring module.
- Another advantage of the invention is to be able to transmit a force towards the cutting members in a direction inclined with respect to the longitudinal direction of the anchor module, this force may have a very high intensity to the extent that we can exert a thrust on the drilling module while bearing on the walls of the excavation through the anchoring in the floor of the anchor module.
- the anchoring module is immobilized in the ground after pivoting the drilling module relative to the anchoring module to correct the trajectory.
- the articulation between the drilling module and the anchor module is performed by a hinge member which can be made by one or more pivot-type links, by a ball-type connection, or by any other type of means. equivalent articulation.

- the anchor module when the anchor module is anchored to the ground in the excavation, it constitutes a stationary support. Also, a thrust exerted on the drilling module by the first path correction means arranged on the anchor module has the effect of rotating the drilling module relative to the anchor module because of the existing articulation between the drilling module and the anchor module.

Also, during the actuation of the displacement means, the lower section carrying the cutting members moves in translation relative to the upper section in the drilling direction.

It is specified that the mass of the anchoring module is preferably greater than that of the drilling module.
- the first trajectory correction means are disposed on the front and rear faces of the drilling module, so as to be able to pivot the drilling module, considered in a first vertical plane, towards the front or rear of the drilling module.
- the front and rear faces are perpendicular to the axes of rotation of the drums.
