    Background of the invention
    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.
    More specifically, it relates to a drilling machine for making excavations in the ground, and more particularly in hard terrain. More specifically, 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 anchor module provided with at least one drilling device; anchoring to block the displacement in the drilling direction of the anchor module relative to the ground by resting 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 realizing drilling at great depth.
    Object and summary of the invention
    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.
    To do this, 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.
    Because of its articulation, 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.
    Preferably, 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.
    It is thus understood that, 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. According to the invention, 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 anchoring module, this force being able to present a very important intensity to the extent that one can exert a thrust on the drilling module while bearing on the walls of the excavation by anchoring in the ground of the anchor module.
    According to another variant, 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. This articulation member may belong to the displacement means, or be arranged between the displacement means and the drilling module, or between the displacement means and the anchoring module.
    According to a first embodiment of the invention, the anchoring module comprises the first trajectory correction means, which are configured to exert a thrust on the drilling module in a direction transverse to the drilling direction, whereby the actuation of the first path correction means rotates the drilling module relative to the anchoring module.
    It is understood that 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. This pivoting takes place along the pivot axis transverse to the drilling direction, the latter being preferably horizontal.
    Preferably, the pivot axis passes through the anchor module.
    Advantageously, the drilling module comprises a lower section carrying the cutting members and an upper section extending at least partly inside the anchoring module, and wherein the first path correction means are arranged between the anchor module and the upper section of the drilling module. The lower and upper sections can be fixed integrally to each other so as to form a one-piece body, or be movable relative to each other.
    Also, the pivoting of the drilling module relative to the anchor module is performed by the action of the first path correction means on the upper section of the drilling module.
    Considered in a plane perpendicular to the drilling direction, the lower section of the drilling module has a length which is preferably substantially equal to the length of the anchoring module. It is the same for the respective widths of the lower section of the drilling module and the anchor module.
    Advantageously, the upper section of the drilling module is movable inside the anchoring module. Preferably, the upper section of the drilling module is movable in translation and in rotation with respect to the anchoring module.
    According to a first variant of the first embodiment, the first trajectory correction means are arranged in the upper part of the anchoring module, while the pivot axis is arranged in the lower part of the anchoring module, in order to benefit from a lever arm substantially equal to the length of the anchoring module.
    In this first variant, the lower section of the drilling module can be slidably mounted relative to the upper section of said drilling 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. The drilling module therefore has a retracted position in which the distance between the cutting members and the upper section is minimal, and an extended position, in which the distance between the cutting members and the upper section is maximum. The assembly consisting of the upper and lower sections is pivotally mounted relative to the anchor module.
    According to a second variant, the anchoring module comprises a body and a longitudinal sleeve in which is slidably mounted the upper section of the drilling module, the longitudinal sleeve being hinged relative to the body. Preferably, the sleeve is pivotally mounted relative to the body along the pivot axis. The first path correction means are configured to push the sleeve to pivot relative to the body of the anchor module, which de facto causes pivoting of the drilling module relative to the anchor module. Preferably, but not exclusively, the first path correction means are disposed on the sleeve.
    Preferably, the upper section of the drilling module extends longitudinally through the anchoring module. Still preferably, the upper end of the upper section protrudes beyond the upper end of the anchor module.
    Advantageously, the drilling machine further comprises second path correction means which are located on the lower section of the drilling module and which are configured to exert a thrust on one of the walls of the excavation in said transverse direction to drilling direction. The concomitant action of the first and second path correction means facilitates the pivoting of the drilling module around the pivot axis by exerting a greater torque on the latter than that exerted by the first correction means of the drilling module. trajectory alone.
    Advantageously, the first path correction means comprise at least one thrust pad.
    In the first variant, the thrust pad exerts a thrust on the upper section of the drilling module, while in the second variant, the thrust pad exerts a thrust on the sleeve.
    Preferably, said thrust pad is actuated by a jack mounted to the anchor module.
    According to a second embodiment, the first trajectory correction means are disposed on the drilling module and are configured to exert a thrust on one of the walls of the excavation in a direction transverse to the direction of drilling, whereby the actuation of the first path correction means rotates the drilling module relative to the anchor module. Since the walls of the excavation remain immobile, it is understood that the actuation of the first path correction means, causing a thrust exerted on the walls of the excavation in a direction transverse to the direction of drilling, has the effect pivoting the drilling module along a pivot axis perpendicular to the drilling direction, which is preferably substantially horizontal. It is specified that the mass of the anchoring module is preferably greater than that of the drilling module.
    Preferably, 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. When the machine is a milling cutter, the front and rear faces are perpendicular to the axes of rotation of the drums.
    The first path correction means may also be arranged on the lateral sides of the drilling module in order to allow pivoting, in a second vertical plane, orthogonal to the first vertical plane, towards one or other of the lateral sides.
    According to another embodiment, the first path correction means comprise a set of motorized actuators configured to pivot the drilling module relative to the anchoring module without necessarily bearing on the walls of the excavation.
    Advantageously, the displacement means are pivotally mounted relative to the anchoring module, preferably along said pivot axis. In other words, the drilling module pivots with the displacement means when the first path correction means are actuated.
    Particularly advantageously, the displacement means comprise at least one thrust device for exerting a thrust on the cutting members oriented in the direction of drilling and directed downwards.
    It is understood that the thrust device ensures that the cutting members remain in contact with the ground to be cut.
    The thrust device preferably comprises at least one thrust cylinder disposed between the anchoring module and the drilling module. Still preferably, the thrust device comprises a pair of thrust cylinders disposed on either side of a median longitudinal plane of the drilling machine.
    Advantageously, the anchoring device comprises at least one anchor pad adapted to bear on one of the walls of the excavation to block the displacement in the drilling direction of the anchoring module relative to the ground.
    The anchor pad extends in a transverse direction, preferably orthogonal to the drilling direction. Preferably, each of the front and rear faces of the anchoring module is equipped with at least one anchor pad.
    Advantageously, on each of the front and rear faces of the anchoring module, the anchor pad or pads define a substantially continuous surface which extends along a height, considered in the longitudinal direction of the anchoring module, at least equal to the two thirds of the height of said drilling module.
    According to another variant, the anchoring device comprises a plurality of airbags disposed on at least one, and preferably both, front and rear faces of the anchoring module. The anchoring of the anchoring module is achieved by inflating the cushions which then bear against the walls of the excavation.
    According to a particularly advantageous aspect of the invention, the drilling machine is provided with damping means to damp the vibrations generated by the cutting members during the drilling.
    According to an exemplary embodiment, the damping means act on the hydraulic circuit which supplies the thrust cylinders. This is for example a hydraulic type of accumulator connected to the hydraulic supply circuit of the thrust cylinder. According to one variant, the damping means could also comprise spring means mounted in parallel with the thrust cylinders.
    In a preferred embodiment, the drilling machine comprises a lift cable at the lower end of which the drilling module is suspended.
    The lift cable extends vertically from a mast of a carrier, known elsewhere.
    Advantageously, the upper section of the drilling module is slidably mounted in the anchor module while being suspended at the lower end of the lift cable.
    According to a preferred embodiment, but not exclusive, said drilling machine is a cutter whose cutting members comprise two pairs of drums which are rotatable about parallel axes of rotation, distinct and perpendicular to the direction of drilling.
    Advantageously, the first path correction means are configured to pivot the drilling module relative to the anchoring module along a pivot axis perpendicular to the drilling direction which is perpendicular to the drilling direction and to the axes of rotation of the drilling units. drums.

    DETAILED DESCRIPTION OF THE INVENTION With the aid of FIGS. 1 to 12, a first variant of a first embodiment of the drilling machine 10 according to the present invention will be described. The drilling machine 10 has the function of performing an excavation E in soil S in a drilling direction DF. In the figures, the vertical direction is illustrated by the reference V. As can be understood by the aid, the direction of drilling DF may be vertical, or slightly inclined relative to the vertical direction V.
    Considered in a horizontal plane, the excavation E has the shape of a substantially rectangular trench and defining substantially vertical walls referenced PI, P2, P3 and P4. The machine has a height H, a length L and a width I. As can be understood from FIGS. 2 and 3, the height H of the machine extends substantially vertically, while the length L and the width I extend in a substantially horizontal plane and substantially define the length and width of the cross section of the excavation E.
    In this example, the drilling machine 10 is a cutter which is suspended at the lower end of a lift cable C which is carried by a lifting mast of a hoist (not shown) known elsewhere.
    The drilling machine 10 comprises an anchoring module 12 which is provided in this example with four anchoring devices 14 which, as will be explained in more detail below, are configured to block the displacement along the drilling direction. of the anchoring module 12 with respect to the ground S while bearing on the walls PI and P2 of the excavation E.
    The anchoring devices 14 comprise anchor pads 16 which are able to bear on the walls PI and P2 of the excavation, as illustrated in particular in FIGS. 4 to 6 and 10 to 12, in order to block the displacement according to the drilling direction of the anchor module relative to the ground during the drilling operation. The anchor pads 16 are actuated by jacks 18 which are configured to exert a horizontal thrust on the anchor pads 16 so that the latter are pressed against the walls PI and P2 vis-à-vis so as to immobilize the anchoring module in the ground.
    In this example, the anchoring module comprises four pads 16 which extend substantially over the entire height of the anchor module 12. Without departing from the scope of the present invention, it would be possible to provide a different number of pads, provided that their number and their area are sufficient to immobilize the anchoring module in the ground during the drilling operations.
    The drilling machine 10 further comprises a drilling module 20 which is provided with cutting members 22. In this example, the cutting members 22 comprise two pairs of drums 24 which are rotatable about axes of rotation A1, A2 parallel, distinct and perpendicular to the direction of drilling DF.
    With reference to FIGS. 2 and 3, it is understood that axes of. rotation A1, A2 extend according to the width I of the drilling machine 10.
    As can be understood from FIGS. 2 and 8, the cutting members are connected to the anchoring module while being movable in translation relative to said anchoring module. To do this, the drilling machine 10 comprises displacement means 35 for translational movement of the cutting members 22 with respect to the anchoring module 12.
    The drilling module 20 has a lower section 26 which carries the cutting members 22 and an upper section 28. The upper section 28 comprises a lower portion 30 and an upper portion 32 which extends longitudinally through the anchoring module 12. 2 and 8, the lower section 26 of the drilling module is slidably mounted relative to the lower portion 30 of the upper section 28 of the drilling module 20. The displacement means, which are configured to move the drilling members relative to the anchor module 12, comprise a thrust device 36, in this case thrust cylinders 37, configured to exert a thrust on the cutting members which is oriented in the direction of DF drilling and directed down.
    In Figures 1 to 6, the drilling module is in the retracted position, that is to say that the distance between the drilling tools 22 and the anchor module 12 is minimal. In this retracted position, the lower section 26 of the drilling module comprises an upper portion 27 which engages in the lower portion 30 of the upper section 28 of the drilling module in FIGS. 7 to 12, the drilling module being in position. deployed position, that is to say that the distance between the drilling tools 22 and the anchoring module 12 is maximum.
    According to the invention, the drilling module 20 is further articulated with respect to the anchoring module 12. In this example, the articulation consists of a pivot axis pivot connection X defined between the anchoring module 12 and the drilling module 20. The pivot axis X is perpendicular to the drilling direction DF and, in this example, extends substantially horizontally. In this first embodiment, the pivot axis X is located between the lower portion 30 and the upper portion 32 of the upper section 28 of the drilling module 20. It is also noted that the pivot axis X is disposed at the top lower end of the anchor module 12. In addition, the upper portion 32 of the upper section 28 of the drilling module 20 extends inside the anchor module 12 and protrudes beyond the end upper 12a of the anchoring module 12. It is therefore understood that the upper section 28 of the drilling module 20 is pivotally mounted about the pivot axis X relative to the anchor module 12. This articulation allows to correct the trajectory of drilling by rotating the drilling module. To do this, the drilling machine further comprises first trajectory correction means 40 which are configured to pivot the drilling module 20 relative to the anchoring module 12 along the pivot axis X. It is also specified that the thrust cylinders 37 pivot with the cutting members 22.
    Referring to FIGS. 5 to 7, it can be seen that, in this first variant of the first embodiment, the first trajectory correction means 40 are arranged on the anchoring module 12, at its upper end 12a, and are configured to exert a thrust in a first direction T1 or T2 in a second direction T2 opposite to T1, both directions being transverse to the direction of drilling DF, whereby the actuation of the first path correction means 40 rotates the module drilling relative to the anchor module around X pivoting tax in one direction or the other. It is also noted that the displacement means 35, in this case the thrust cylinders 37, are pivotally mounted relative to the anchoring module 12 about the pivot axis X.
    More specifically, in this first variant, the first trajectory correction means 40, located at the upper end 12a of the anchoring module 12, are arranged between the upper end of the anchoring module and the upper part of the section. upper 28 of the drilling module, so that a thrust exerted by the first path correction means 40 has the effect of rotating the drilling module around the pivot axis X. As seen in Figure 7 , the first path correction means 40 are arranged on either side of the upper portion of the upper section 28 of the drilling module.
    For example, in FIG. 5, when the first trajectory correction means 40 exert a transverse thrust T1 directed towards the wall P2 of the excavation E, this has the effect of rotating the drilling module around the pivot axis X in the direction of rotation SI, which has the effect of bringing the cutting members 22 of the opposite wall PI, as shown in FIG. 5. Considered in a plane perpendicular to the pivot axis X, the direction of drilling DF has an angle α with respect to the lower direction. Conversely, as illustrated in FIG. 6, a thrust exerted by the first trajectory correction means 40 in a direction T2, opposite to the direction T1, has the effect of rotating the drilling module relative to the anchoring module of FIG. an angle a2 about the pivot axis X in a direction of rotation S2 opposite to the direction of rotation SI, whereupon the cutting members tend to move towards the wall P2 of the excavation E.
    The first trajectory correction means 40 comprise thrust pads 42 which are actuated by the jacks 44 mounted at the upper end 12a of the anchoring module 12.
    Referring again to FIG. 2, it can be seen that the levitation cable C is fixed by its lower end C1 to a fastener 41 which is secured to the upper end of the upper part 32 of the upper section 28 of the drilling module 20. As mentioned above, the upper end of the upper portion of the upper section of the drilling module protrudes beyond the upper end 12a of the anchoring module 12.
    With reference to FIG. 1, it can be seen that the drilling machine further comprises second path correction means 43 which are located on the lower section 26 of the drilling module 20 and which are configured to exert thrust on the walls. excavation PI, P2 transversely to the drilling direction DF. Also, the concomitant actuation of the first and second path correction means 40, 43 facilitates the pivoting of the drilling module 20 relative to the anchoring module 12 about the pivot axis X.
    In this example, the second path correction means 43 are pads disposed on the front and rear faces of the lower section of the drilling module 20.
    In this example, the drilling machine 10 is provided with damping means 45 for damping the vibrations generated by the cutting members 22 during the drilling. In this variant, the damping means 45 comprise a damping hydraulic device which is connected to the hydraulic circuit feeding the thrust cylinders 37.
    An example of use of the drilling machine 10 will now be described. During drilling of the floors, after introduction of the drilling machine 10 into the ground, the anchoring devices are actuated in order to immobilize the drilling module. 12, as shown in Figure 4. Then, the cutting members being activated, it actuates the thrust cylinders 37 to push on the cutting members. Finally, the drilling module is rotated to correct if necessary the direction of drilling DF. According to another example of use, the drilling direction is corrected, then the anchoring devices are actuated before activating the cutting members and actuating the thrust cylinders. With the help of Figures 13 to 20, will now be described a second variant of the first embodiment of the drilling machine 110 according to the invention. The drilling machine 110 comprises an anchoring module 112 which is provided with four anchoring devices 114 for blocking the displacement in the drilling direction of the anchoring module 112 relative to the ground S, in particular during the drilling operation. , taking support on the walls PI, P2 of the excavation E.
    The anchoring devices 114 comprise several deployable anchor pads 116 which are able to bear on the walls PI, P2 of the excavation E to block the vertical displacement of the anchor module relative to the ground S. In this second In the embodiment, the anchoring devices 114 extend over the entire height of the anchor module, the anchors forming four rows extending along the lateral ends of the front and rear faces of the drilling module.
    The drilling machine 110 further comprises a drilling module 120 which is provided with cutting member 122, similar to the cutting members of the first embodiment. These cutting members are connected to the anchoring module 112 while being movable in translation relative to said anchoring module.
    The drilling machine 110 comprises displacement means 135 for moving the cutting members 122 relative to the anchoring module 112, these moving means comprising a thrust device 136, comprising thrust cylinders 137 arranged between the module anchorage and the drilling module. This thrust device 136 is configured to exert a thrust on the cutting members 122 oriented in the direction of drilling DF and directed downwards. The drilling module has a lower section 126 carrying the cutting members 122, and an upper section 128 which extends inside the anchoring module 112.
    More specifically, the upper section 128 of the drilling module is slidably mounted inside the anchor module 112 in the longitudinal direction of the anchoring module. The actuation of the thrust cylinders 137 has the effect of moving the assembly consisting of the lower section 126 and the upper section 128 of the drilling module relative to the anchoring module, as illustrated in FIGS. 19 and 20. Like the first variant, the actuation of the thrust cylinders 137 is preferably carried out after the anchoring module 112 is immobilized in the ground. In FIGS. 16 and 20, the drilling machine 110 immobilized in the ground S is illustrated by the actuation of the anchoring devices 114. FIG. 20 shows the machine of FIG. 16 after actuation of the thrust cylinders 137 which exert a downward thrust on the cutting members 122.
    According to the invention, the drilling module 120 is further articulated with respect to the anchoring module 112. Like the first embodiment, this articulation consists of a pivot connection about a pivot axis X allowing a pivoting of the drilling module 120 relative to the anchoring module 112 as in the first variant, the pivot axis X and substantially horizontal.
    Referring to FIG. 13, it can be seen that the upper section 128 of the drilling module 120 is in the form of a longitudinal bar which is engaged in a sleeve 160 articulated with respect to the body 161 of the anchoring module 112. It is easy to understand this sleeve 160 belongs to the anchoring module 112 and forms a tube through which the upper section 128 of the drilling module 120 can slide. This sleeve 160 is pivotally mounted relative to the body 161 of the anchoring module around the pivot axis X.
    Also, the pivoting of the drilling module 120 relative to the anchoring module 112 is achieved by pivoting the sleeve 160 relative to the body 161 of the anchoring module 112 about the pivot axis X, the pivoting of the sleeve 160 causing the pivoting of the upper section 128 of the drilling module, and thus the pivoting of the drilling module 120 in the direction of rotation SI, or in the direction of rotation S2.
    It is specified that the thrust cylinders 137 are disposed between the sleeve 161 and the lower section of the drilling module, so that the thrust device 136 pivots with the drilling module 120.
    To perform this pivoting, the drilling machine comprises first trajectory correction means 140, better visible in the detail view of FIG. 17, which are actuable and configured to pivot the sleeve 160 relative to the body 161 of the module. anchoring around the pivot axis X. In the example of FIG. 17, the drilling direction DF corresponds to the longitudinal axis of the upper section 128 of the drilling module, and thus also corresponds to the longitudinal direction of the drilling unit. sleeve 160. It is understood that the pivot axis X is perpendicular to the drilling direction DF. It can also be seen in this FIG. 17 that the displacement means 135, in this case the thrust cylinders 137, are pivotally mounted with respect to the anchoring module 112 around the pivot axis X.
    The anchoring module 112 comprises the first trajectory correction means 140, which are configured to exert a thrust on the drilling module 120 in a direction T which is transverse to the drilling direction DF, whereby the actuation of the first path correction means rotates the drilling module relative to the anchor module. To do this, the first path correction means 140 are arranged between the sleeve 160 and the body 161 of the anchor module, so that the actuation of the first trajectory correction means 140 along the direction T has the effect of rotate the sleeve 160 relative to the body 161 of the anchoring module around pivoting tax X.
    In this example, the first trajectory correction means 140 comprise thrust pads 142 which are actuated by jacks 144 mounted on the sleeve 160 of the anchoring module.
    In Figure 21, there is illustrated a second embodiment of the drilling machine 210 according to the invention. The drilling machine 210 is similar to that of the second variant of the first embodiment.
    The elements of the machine 210 figure 21 which correspond to those of the drilling machine 110 illustrated in FIGS. 17 and 18 bear the same references, increased by the value one hundred.
    The drilling machine 210 differs from that of FIG. 18 essentially in that, in this second embodiment, the first path correction means 280, 282 are disposed on the drilling module 220, and more particularly on the front face 271 and the rear face 273 of its lower section 226.
    The first path correction means 240 are configured to exert thrust on one or other of the walls PI and P2 of the excavation in a direction transverse to the direction of drilling.
    In the example of FIG. 21, the first trajectory correction means comprise thrust pads which extend along the height of the lower section 226 of the drilling module 220 and which are configured to deploy transversely in order to push on. one or the other of the walls PI and P2 in the desired direction of rotation. In this example, each of the front and rear faces has a pair of thrust pads. The actuation of the first path correction means has the effect of pivoting the drilling module relative to the anchoring module around the pivot axis X.
