Definitions

  • the invention relates to a trailer of a follower train for a tunnel boring machine.
  • Tunneling machines are known, called tunneling machines, which have a large mobile structure consisting of a large mobile plant at the front of which is disposed a shield having a section compatible with the future section in line with the final shape. of the tunnel (tunnel of circular, bilobed, rectangular section %)
  • the front part of the shield which comes into contact with the cutting face to cut the geological formation traversed by the tunnel comprises a cutting head supporting working tools and driven in rotation at a determined speed which depends on the nature ground to dig.
  • the TBM has a follower train, also known as a back-up, which advances at the same time as the cutting head when digging the tunnel.
  • This following train travels on a taxiway resting on the concrete envelope of the tunnel and consists of several trailers (or wagons) containing the various operating modules, such as for example the power supply devices, the hydraulic systems , air supply and ventilation devices or even sanitary rooms.
  • the various operating modules such as for example the power supply devices, the hydraulic systems , air supply and ventilation devices or even sanitary rooms.

  • the document JP H11 30096 describes a trailer of a train following a tunnel boring machine according to the preamble of claim 1. More specifically, the trailer comprises a carriage mounted on casters and configured to transport segments by moving on a chassis located in the lower part of the trailer. To this end, the carriage is guided along the trailer using rails, extending on either side of the carriage, and moved by the wheels.
  • the document JP 2006 200296 describes a method of constructing a tunnel allowing sufficient construction at high speed by the early construction of a floor slab.
  • An objective of the invention is therefore to propose a solution to the problems described above, and more particularly a trailer including a larger space to allow the passage of operators and maintenance operations, without penalizing its capacity to transport operating modules, and which also makes it possible to simplify logistics operations and limit the risks of co-activity, thereby increasing the level of safety within the train follower in operation.
  • the conveying means comprise two superimposed tracks of the double rail or hatch type.
  • the invention also comprises a train following a tunneling machine comprising at least one trailer as described above.
  • the invention provides a tunneling machine comprising a follower train as described above.
  • a tunnel boring machine 1 comprises, in the front part, a shield 2 having a substantially circular section whose diameter corresponds to the diameter of the tunnel which is dug.
  • the shield 2 is provided with a cutting head which comes into contact with the cutting face to dig the tunnel.
  • the tunnel boring machine 1 also comprises a follower train 3 extending behind the shield 2 and which advances at the same time as the cutting head during the digging of the tunnel.
  • the follower train 3 moves on a taxiway 5 resting on the concrete envelope formed by segments 7 of the tunnel.
  • the following train 3 is made up of several trailers 10 (or wagons) which include the various operating modules 6.
  • the following train 3 includes several trailers 10: a suspended trailer (also called a "bridge” ”) 8, connected to an erector (part of the shield) and configured to set up segments 7 against the wall cut by the cutting head, four or five central trailers 10 comprising the operating modules 6, and two trailers rear 9 configured to load the segments 7 in the following train 3.
  • the trailer 10 is therefore directly used to transport the segments 7 from the rear of the follower train 3 by cooperating with a support 40, without requiring the use of a VMS 4. This therefore makes it possible to greatly reduce the size of the passage necessary for allow the supply and return of the segments 7, since a simple support 40 moving or being moved along conveyor means 30 is sufficient. The volume thus gained can be used for the realization of one or more corridors for operators, maintenance operations or even the transport of parts.
  • the trailer 10 may include a support 40.
  • each central trailer 10 comprises conveying means 30 fixed in their lower part 21 in order to allow the support 40 to move from the rear part of the central trailer 10 furthest from the shield 2 towards the front part of the central trailer 10 closest to the shield 2.
  • the conveying means 30 of a given trailer 10 are therefore connected to the conveying means 30 of the next trailer 10 in order to allow the transfer of the support 40 from a trailer 10 to the 'other.
  • This configuration can make it possible, depending on the size of the tunnel, to store in the follower train 3 at least all of the segments 7 necessary to make a complete ring of the tunnel.
  • the rear trailers 9 can either include conveying means 30, or a housing configured to receive a VMS 4 in order to bring the segments 7 to the central trailers 10 and allow their loading onto the support (s) 40 (s) of the central trailers 10.

  • the conveying means 30 may comprise at least two superposed tracks.
  • the tracks can be formed by rails or a conveyor.
  • the conveying means 30 comprise at least one rail 32.
  • the support 40 then comprises means configured to cooperate with the rail 32 and thus allow the movement of the support 40 along the rail 32.
  • the support 40 can be placed on the rail 32, in which case the segment 7 can be placed on the support 40, or alternatively be suspended from said rail 32, in which case the segment 7 is fixed on the support 40.
  • the conveying means 30 comprise two parallel rails 32 and the support 40 comprises a carriage comprising associated displacement means, for example wheels 42 of the rail wheel type 42 comprising a tread, at least one flange (preferably two) and a bandage.
  • the support 40 is therefore placed on the rails 32.
  • the rails 32 extend in a horizontal plane (parallel to the ground).

  • These shims 45 can be substantially identical to those described above.
  • the support 40 brings the segments 7 by moving along the rails 32 from the rear of the trailer 10 towards the front of the trailer 10 (that is that is to say towards the shield 2), where the segments 7 are unloaded, then returns by moving along these same rails 32 to the rear of the trailer 10 in order to allow it to be reloaded with new segments 7.
  • the support 40 is unloaded by a mechanism configured to place the segments 7 at the disposal of the erector for their attachment to the wall of the tunnel.
  • the conveying means 30 comprise two superimposed tracks formed by two pairs of rails 32 extending in parallel two by two, one of the pairs of rails 32 being configured to transport the support 40 loaded with segments 7 towards the shield 2 while the other pair of rails 32 is configured to bring the support 40 empty towards the rear of the follower train 3.
  • the pairs of rails 32 are preferably superimposed, that is to say that they extend generally one above the other (in a vertical direction, that is to say perpendicular to the layout tunnel).
  • This configuration in fact makes it possible to reduce the space required on the ground for the conveying means 30 and the supports 40 while leaving a sufficient volume above the supports 40 to arrange the corridor for the operators, the maintenance and the transport of parts. .

  • the segment 7 is therefore placed on the support 40 so its greatest length is parallel to its direction of travel.
  • the axis defining the curvature of the convex face of the segment 7 is perpendicular to the direction of movement.
  • the segment 7 is then unloaded onto a gripping table of the erector.
  • the plate 50 is lowered in order to place it in line with the pair of lower rails 32, and turned again by 90 ° (in one direction or the other) in order to position the wheels 42 of the support 40 opposite the rails 32 ( figure 5b ).
  • the support 40 is slid over the lower rails 32 and returned empty to the rear of the follower train 3.
  • the support 40 may comprise a motor configured to rotate all or part of its wheels 42 so as to allow its movement along the rails 32.

  • the support 40 comprises two pairs of studs 47 fixedly attached to two chains and configured to support one or more segments 7.
  • the studs 47 are of substantially rectangular shape, a rod projecting from each of said studs 47, and the segment 7 is placed in balance on the four rods.
  • the studs 47 can be connected two by two in order to stiffen the support 40.
  • the segment 7 is also placed on the support 40 so that its greatest length is parallel to its direction of movement in order to minimize its bulk, it can be envisaged to receive the segment 7 on a turntable 50 in order to rotate it 90 ° before it is gripped by the erector.
  • the plate 50 can only be a rotating plate and that it is not necessary for this plate to be able to move vertically.
  • the support 40 then has a substantially smooth lower face configured to slide on the conveying rollers or the spherical balls and to interface with the rollers or the balls so as not to risk damaging the segments 7 during their displacement.

  • supports 40 can be stored in a row in the central trailers 10, so that the follower train 3 can transport a large number of segments 7 at the same time, this number being sometimes sufficient to produce a complete segment of segments 7 covering the entire periphery of the tunnel to be built.
  • the volume thus recovered corresponds to the central corridor 12, which is delimited by the central plate, the uprights 26 and the upper part 26 of the chassis 20 (front, rear and side crosspieces) (see figure 2 ).
  • This central corridor 12 thus allows operators to circulate on a different lane from that used by the means of transport of segments, which eliminates the risks of coactivity between operators and different vehicles.
  • This passage also simplifies logistics operations, notably by facilitating maintenance operations and transporting consumables.
