  • the conveyor 42 extends from the end of the conveyor 41 opposite the felling shield 130, up to the interior of the zone defined by the partitions 251 and 252, and therefore crosses the partitions 252 and 253.

  • the reference numeral 18 designates a central front part, that is to say a part of tapered shape and oriented towards the front of the body 1, which constitutes the end of the central shaft 15 on the side of the front end 11.
  • the central front part 18, which is provided with complementary tools 184 is arranged so as to project outwards from the body 1, that is to say the peripheral cutting edge 110. Also, since this central front part 18 rotates around XX ′ when the shaft 15 is rotated, the latter can carry out a pre-felling, or felling blank, at the center of the cutting face F.
  • FIG. 3 shows another embodiment of the central front part which can be mounted at the end of a central shaft 15, and which is designated at 18 '.
  • This front part 18 ' which is shown without additional tools but which can be provided with it, has the particularity of being not fixed on the shaft 15, but guided in sliding in the direction of XX' under the effect of a double-acting cylinder shown diagrammatically at 181 and disposed in the axial recess of the shaft 15, so that the latter can carry out a deeper felling blank by moving in a direction of advance approximately parallel to A

  • each pivoting flap of the shield 130 is constituted by a sliding pivot, the pivot and sliding axis of which here consists of a bar is oriented along a radius of the central shaft 15, and therefore of the body 1. Consequently, the pivot axis of a flap is approximately parallel to the axis of its third articulation 54.
  • the mobile part which is here constituted by an eyelet crossed by the guide bar mentioned above, is fixed to the corresponding flap. More precisely, as is clear from FIG. 1, each flap has the shape of a portion of a circle, that is to say of a V, each free end of which is connected by an arc of a circle.
  • each flap 141 to 148 is connected to one of the articulations 54, 154 or 114 of this flap.

It is on this disc 52 that the fixed part of the articulation in the form of a sliding pivot 54 of each flap is fixed. Obviously, it is also possible to provide elements for guiding the external periphery of the disc 52, which would cooperate with the internal casing 2 of the body 1. Near the central shaft 15, the disc 52 cooperates with a ball stop or the like.

This sliding takes place between a position of the ball stop 51, and therefore of the disc 52 which corresponds to the open state of the shield 130, and a position corresponding to its closed state.
  • each of the jacks 5 are fixed to the transverse partition 252, for example by welding, and passes through orifices suitable made in the transverse wall 253.
  • These cylinders have their longitudinal axis of sliding disposed substantially parallel to the axis XX '. It goes without saying that other arrangements which do not necessarily include a sliding pivot and jacks can also be provided, as long as they allow both the flaps 141 to 148 to pivot about their axis, and this preferably by allowing the central shaft 15 to rotate simultaneously.
  • the flaps 141 to 148 of the shield 130 each extend along a plane roughly parallel to the axis XX ′, or with a small angle relative to to this one.
  • the area along a plane perpendicular to XX 'of the openings 161 to 168 of the shield 130 is maximum, and therefore substantially equal to the opening of the cutting edge 110.
  • the rods of the jacks 5 are returned to the bodies of these, so that the total length along XX 'of these cylinders is minimum. As can be seen in FIG. 1, this length corresponds to the distance between the transverse partition 252 and the disc 52.
  • the part secured to the flaps of the joints 54 is in its position closest to the central shaft 15.
  • the flaps 141 to 148 can be at least partially closed, to limit the penetration of cuttings towards the carpet 41.
  • the angle of the tools 14 can be adjusted with respect to the direction of XX ', and this continuously during the advance of the tunnel boring machine T.
  • This tunnel boring machine T is also particularly safe insofar as it makes it possible, in the event of the front F collapsing and / or if sludge or liquids have tended to enter the boring tunnel through the front end 11 the shield 130 until sufficient drying of the soil to start the felling is carried out.
  • the tunnel boring machine T which has been described allows a quick and free transformation from a mud front type to a full section shield type, for example in the case of the ground S where a gallery G must be dug changes its structure as the TBM advances along the next A.
  • Yet another advantage of the TBM specific to the invention is that it provides visibility to its operator, for example if the operator This is in cabin 26, so that the felling and / or advancement parameters of this TBM can be permanently adjusted, depending on the structure of the ground which constitutes the size F front.
  • the TBM according to the invention has considerable advantages. It allows you to vary the felling angle depending on the state of the ground. The harder the ground, the greater the felling angle and the more the shutters can be opened. When the ground is less hard or soft up to a state close to the liquid state, the angle of slaughter will be reduced by closing the flaps until complete obturation. The variation of the angular position of the flaps also makes it possible to regulate the amount of earth extracted. In addition, the flaps produce a guiding effect on the soil which has been removed, so that it is transmitted to the conveyor 41.
