    [0001] BACKGROUND OF THE INVENTION Track support of a ground power supply system for a land vehicle, rail comprising such a support and method of implementation The field of the invention is that of ground-based power supply systems for a vehicle of land transport, including a tramway. More particularly, the invention relates to a track support type track support of a ground power system for a land vehicle, including a tram, in the form of a profile of an electrical insulating material, comprising: a substantially planar upper surface, provided with a longitudinal groove for receiving a track segment, and a longitudinal groove for receiving a low voltage power supply cable; and a lower surface for resting on a base for holding the support in the roadway. A ground power system is comprised of a plurality of rails longitudinally connected to one another via junction boxes. Each rail includes a power track support and a power supply track, which is constituted by a plurality of conductive segments separated longitudinally by insulating segments. FR 2 938 800 discloses a track support in the form of a honeycombed fiberglass profile, comprising an upper surface, substantially flat, provided with a single longitudinal groove for receiving the segments of the track, and a flat bottom face, intended to bear on the ground. The profile comprises a core connecting the upper face to the lower face which is provided with at least one longitudinal supply duct, adapted to receive a high low voltage supply line intended to be connected to the conductive segments to bring them to a potential adapted to the needs of the vehicle. The groove and the supply duct of a profile are centrally disposed and symmetrical with respect to a longitudinal median plane of the support, perpendicular to the upper face thereof. For the case of a tramway, such a support is about 11 m long.
    [0002] The method of implantation of such a support consists in making a trench in the roadway to be equipped with such a ground feeding system. Once the trench is cleared, a concrete slab is poured to form a flat surface at the bottom of the trench. The track supports are then placed on metal saddles fixed to the floor. Then, a scuffed sill is cast below and on the sides of the runway support to ensure its anchoring in the roadway.
    [0003] The supports are connected mechanically two by two by a junction box consists essentially of a pair of fishplates, on either side of the longitudinal axis of the supports and a metal cap closing, from above, the junction box.
    [0004] The power cable is placed in the central conduit of the supports and connected to a conductive segment. Finally, the different insulating and conducting segments are fixed in the groove of the profile. The insulating segments are fixed by gluing while the conductive segments are fixed by gluing and screwing on a support.
    [0005] Such a support presents different problems. A first problem is related to the maintenance of the system. In case of an operational accident or simply in case of wear of the various components of a rail, it is necessary to replace this component. If it is a matter of replacing a segment, in particular a conductive segment, the latter being fixed by gluing and screwing to the support, the separation of the segment of the support often leads to the degradation of the support itself. The replacement of the support is extremely complex. It involves breaking the concrete sill so as to clear the saddles of the support to be replaced. Then, it is a question of taking again the different steps of implantation mentioned above to install the new support. Such a maintenance operation necessarily takes a lot of time (about 1 month). It will be understood that, when it comes to performing a maintenance operation at a busy road junction, in the heart of a city for example, it is necessary to reduce the intervention time.
    [0006] A second problem lies in the robustness of the support. It turns out to practice that a honeycomb and fiberglass profile has insufficient mechanical strength. A third problem is related to the realization of curves. In a monobloc version of the track support, it can be slightly bent so as to have a radius of curvature greater than or equal to 95 m. A monoblock support can not be bent further. However, such a support must be bent at the factory and then supplied at the location. To make curves having a lower radius of curvature, a multiblock version of the support presented above has been proposed. According to this version, the core of the support is subdivided into three narrower sections, along two cutting planes parallel to the median plane of the support. Each section of the support can be bent with a radius of curvature of less than 95 m to obtain radii of curvature as small as the turning radius of the vehicle using the feed system. For a tramway, the turning circle is about 18 meters. However, these three sections of the support must be bent at the factory and fixed together at the factory, before the support thus produced is supplied at the location. We understand the logistical difficulties encountered during the implementation of such a support. The invention therefore aims to overcome these problems by providing in particular a clean support to be easily detached its concrete base and which has increased robustness. The invention relates to a track support of the aforementioned type, characterized in that the lower surface is curved, preferably in the form of a "V", so that the support is curved so as to be maintained, at least transversely, in a recess of complementary shape made in the base for holding the support in the roadway. According to advantageous but not obligatory aspects of the invention, such a support can incorporate one or more of the following characteristics, taken in any technically permissible combination: the lower surface of the support is crenellated in a longitudinal direction of the profile which constitutes the support of so as to be maintained, at least longitudinally, in the recess of complementary shape made in the base. - The lower surface comprises transverse slats involved in maintaining the support position in the recess. - The support is made of material, and in that the support is made of an elastomeric material, so that the support is elastically deformable. - Side edges of the support, connecting the lower surface and the upper surface, are provided with through holes for the insertion of studs for direct attachment of the support in the base. a bottom of the groove is in communication with the groove, and flanges of the bottom of the groove situated on either side of the groove are provided with recesses for accommodating the means for attaching a segment to said support; . - Each side wall of the groove has a lateral passage opening into an associated recess in the bottom of the groove, to allow the introduction of a bacon at the bottom of said recess for receiving by screwing a bolt for securing a segment on said support. the upper surface has lateral faces disposed on either side of the groove, each of the faces being inclined so as to have a tilt angle b with respect to a horizontal plane, the tilt angle being between 0 and 4 °, in particular 2 °. - Each side face of the upper surface of the support comprises a drawing promoting the flow of water, and the adhesion to the support. each lateral edge of the support is provided with a channel extending longitudinally through the support and interconnecting the two transverse end faces of the support, said channel being intended to receive an antenna cable. the support has a reduced length and the groove constitutes a cavity, each transverse end face being provided with an orifice opening into the cavity adapted to receive the end of a feed tube of a power cable low voltage and / or antenna cable. - Each side edge of the support being provided with a channel extending at an angle so as to connect a transverse side end face of the support to a side wall of the groove for the circulation of an antenna cable. The invention also relates to a method for installing a support according to the previous support, characterized in that it comprises the steps of: clearing a trench in a roadway; pour a concrete slab; by means of a template, position the support, the support being provided with anchor pins placed in the through holes which are provided with the lateral edges of the support, the support possibly being constrained to give it a suitable radius of curvature; pouring a concrete base substantially up to the height of the upper face of the support; screwing, through the through holes, the support to the base of support of the support in the roadway.
    [0007] The invention also relates to a rail of a ground supply system, characterized in that it comprises a plurality of support arranged end to end on a concrete base for holding said supports in the roadway, each support being a support according to the preceding support, and a plurality of conductive and insulating segments, two successive conductive segments being separated from each other by at least one insulating segment, the segments forming together the track and being received in the grooves of the supports. Preferably, two successive supports are secured to one another by means of a junction sheet shaped so as to have a shape complementary to that of the lower surfaces of the supports to be connected and suitable for avoiding possible electrical leaks. Another subject of the invention is a method for installing a rail conforming to the preceding rail, characterized in that it comprises the steps of: clearing a trench in a roadway; pour a concrete slab; by means of a template, position the various supports constituting a section of rail and the tube for feeding the antenna and low-voltage supply cables, the supports being provided with anchor pins placed in the through holes of which are provided with the lateral edges of each support, the supports possibly being constrained to give them a suitable radius of curvature; pouring a concrete base substantially up to the height of the upper face of the supports; circulating the antenna cable through the media channels and connecting the low voltage power cable to the conductive segment of the rail section; bolting the conductive segments and the insulating segments of the track of the rail section into the grooves of the various supports. The invention and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a support according to its principle, given solely by way of example and with reference to the accompanying drawings in which: Figure 1 is an exploded perspective representation of the various elements of a rail section of a ground power system for a tram; Figure 2 is a diagrammatic perspective view of an intermediate support of the rail section of Figure 1; Figure 3 is a perspective view downwardly of the support of Figure 2; Figure 4 is a partial top view of the intermediate support of Figures 2 and 3: Figure 5 is a section in a transverse plane of the intermediate support of Figures 2 and 3; Figure 6 is a diagrammatic perspective view of a junction support between two rail sections; Figure 7 is a section along a median plane of the junction support of Figure 6; Figure 8 is a cross-sectional view of the junction support of Figure 6; Figure 9 is a low-angle view of a junction support between the ends of two intermediate supports and a supply tube antenna cables and low voltage supply; Figure 10 is a perspective view of a joining sheet between two intermediate supports of a rail section of Figure 1; and, Figure 11 is a flowchart of a method of implementing the ground feeder system in a pavement.
    [0008] Referring to Figure 1, a ground power system 10 is intended to be implanted in a roadway 12 between the two rails 13 and 14 running the tram. The system 10 comprises a rail 20 held in position in the roadway 12 by a base 22.
    [0009] The system 10 also comprises a low voltage supply means and a detection means of a tramway. A rail 20 is constituted by a track support 24 and a track 26. The track 26 is housed in a groove of the track support 24. The track support 24 is formed by the assembly in a longitudinal direction Z of several sections of Track support 30 via a junction support 32. Such a track support section is shown in FIG. 1. A track section is itself composed of a plurality of intermediate supports. In the embodiment shown in FIG. 1, a track support section 30 successively comprises a first intermediate end support 34, a first central intermediate support 36, a second central intermediate support 36, a second intermediate intermediate support 34. For the sake of clarity, in FIG. 1, only a first half of the runway support section 30 is shown, the second half of the runway support section 30 being symmetrical to the first relative to a transverse plane P. The track 26 is made by assembling, in the longitudinal direction Z, a plurality of segments comprising conductive segments 44 and, between two successive conductive segments, insulating segments 42. As illustrated in FIG. , an insulating segment 42 covers a connecting support 32 and the adjacent end portion of the two intermediate end supports 34 connected by this sup junction port. A conductive segment 44 covers the portion, which is not covered by the insulating segment 42, of each intermediate end support 34 of a support section, as well as the first and second central intermediate supports 36.
    [0010] An insulative segment 42 is made of an insulating material of the electric current, while a conductive segment 44 is made of a metallic material conductive of the electric current. The segments have a parallelepiped plate shape with a thickness e and a small width L in front of their length L. Referring now to FIGS. 2 to 5, a central intermediate support 36 will be described in detail. The support 36 is a solid profile extending along the longitudinal axis Z. The support 36 is made of an elastomer material based on natural or synthetic rubber, such as EPDM (according to the acronym "ethylene-propylene- diene monomer "). In this way the support 36 has a certain elasticity. In particular, the support 36 can be deformed elastically by applying a suitable force, so as to confer a predetermined radius of curvature support 36 when producing a curved rail.
    [0011] Such elastomeric material also has high impact resistance and good electrical insulation. Without constraints, the support 36 is symmetrical with respect to a median plane XZ, the X axis being intended to be arranged substantially vertically when the support 36 is implanted in the roadway 12.
    [0012] The support 36 has an upper surface 50, a lower surface 52, side edges 53 and 54, interconnecting the upper and lower surfaces. The support 36 also has transverse end faces 55 and 56. While the upper surface 50 is substantially planar and is intended to be disposed in a substantially horizontal plane when the support 36 is implanted, the lower surface 52 is, in section transverse, curved so that the support is bulged outwardly and can be received and maintained transversely in a recess of conjugate form formed in the base 22. Preferably, the lower surface 52 has a shape "V". More specifically, in a transverse section (shown in FIG. 5), in the vicinity of the median plane XZ, the lower surface 52 has a central section 522 in the form of an arc which extends towards the lateral edge 53, respectively 54, by a section lateral 523, respectively 524, substantially rectilinear. The opening half-angle of the "V" of the lower surface 52 is large, between 70 and 80 °. Such a shape of the lower surface 52 allows a good distribution of efforts. It also allows the support is easily removed from its housing in the base 22.
    [0013] Alternatively, the central section of the lower surface 52 is wider and the angle is smaller, the support then becoming more trapezoidal, see rectangular. However, such a shape requires the use of a larger amount of material for producing the medium, which therefore has a higher cost. In addition, the lower the angle is, the more difficult it is to extract the support out of the base, which complicates the maintenance operations. The thickness of the support 36 thus decreases from the median plane XZ to each lateral edge 53, 54. Longitudinally, the lower surface 52 is crenellated. The transverse ribs 51 thus formed in the surface 52 contribute to holding the support 36 in position in a conjugated recess 23 made in the base 22. The upper surface 50 is provided with a groove 60, longitudinal and central, comprising a bottom 62 and lateral walls 63 and 64 respectively. The dimensions of the groove 60 are adapted to those of a segment, so as to fitably receive such a track segment. More precisely, the width of the groove corresponds to the width I of a segment, and the depth of the groove corresponds to the thickness e of a segment. Therefore, in position, a segment is flush with the upper surface 50 of the support on which it is attached. The support 36 has a groove 70, longitudinal and central, which opens on the bottom 62 of the groove. The groove 70 comprises a bottom 72 and side walls respectively 73 and 74. The groove 70 opens on the transverse end faces of the support 36. The groove 70 is intended to allow the circulation of a low voltage power cable, belonging to the supply means of the system, from a transverse end face of the support 36 to a mechanical and electrical connection point to the conductive segment 44 received in the groove 60 of the support 36. A segment received in the groove 60 is fixed to the support 36 only by a bolt-nut assembly (not shown in the figures). For the reception of such fixing means, the support 36 comprises, on the bottom 62 of the groove 60, on either side of the groove 70, and regularly spaced longitudinally, a recess 68. The recess 68 is extends parallel to the X axis. It has, in a plane orthogonal to the X axis, an elliptical section, the major axis of which is oriented along the axis Z. At the right of a recess 68, the side wall 73, respectively 74, the conduit 70 has a passage 69 extending substantially along the Y axis and opening at the bottom of the recess 68 corresponding. The passage 69 also has an oblong shape along the longitudinal axis. Such a passage allows the installation of a bacon at the bottom of the recess 68. A bolt inserted into a spacer through a suitable hole which is provided with the segment to be fixed and inserted into the recess 68 to be associated, by screwing, gibbered previously positioned at the bottom of this recess 68. A lateral edge 53, respectively 54, is provided, regularly spaced longitudinally, through holes 83, 84. A hole 83, 84, connects the upper surface 50 of the support 36 at the bottom surface 52 thereof. A hole 83, 84 has an internal shoulder. A hole 83, 84 is adapted to receive a fixing stud by screwing the support 36 in the base 22 for holding the support in the roadway 12. The head of the stud bears on the shoulder of the hole 83, 84, to maintain the support 36 integral with the base 22. Each lateral edge 53, respectively 54, also comprises a channel 85, respectively 86, extending longitudinally and opening on the transverse end faces 55, 56 of the support 36. Such a channel is intended receiving an antenna cable belonging to the detection means of the presence of a tram. The upper surface 50 of the support 36, has on each side of the groove 60, side faces 93 and 94. A side face 93, 94 has, in a transverse plane, a tilt angle b with respect to a horizontal plane, of so that said lateral face is inclined from the median plane XZ to the corresponding lateral edge 53, 54. The tilt angle b is for example 2 °. This promotes the flow of rainwater on the rail. In addition, each side face 93, 94 has a relief pattern. This further improves the flow of water and increase the coefficient of friction between the support and the wheel of a vehicle rolling on the rail, to promote adhesion.
    [0014] The support 36 just described is a central intermediate support. A similar description could be made of an intermediate end support 34. The only difference between these two types of intermediate supports lies in the fact that on a first portion of the support 34, the groove 70 has a first width, while on a second portion of the support 34, the groove 70 has a second width, the first width being smaller than the second width, the second width being equal to that of the groove 70 of a central intermediate support 36. The first portion of the support 34 corresponds to the portion to be covered by an insulating segment 42, the second portion of the support 34 corresponding to the portion to be covered by a conductive segment 44. The first width is substantially equal to the diameter of the low voltage supply cable so as to pinch lightly to keep it in position. The second width accommodates means for mechanical and electrical connection of the power cable to the conductive segment 44. In Figures 6 to 9, a junction support 32 between two track support sections is shown.
    [0015] A junction support constitutes an alternative embodiment of an intermediate support, such as the support 36 described previously in detail. Accordingly, an element of the junction support 32 similar to an element of the support described in FIGS. 2 to 5 is identified by the same reference numeral increased by a hundred.
    [0016] The junction support 32 thus has an upper surface 150. The junction support 32 has a lower surface 152 of generally "V" shape. The thickness of the junction support 32 is greater than that of the support 36. Since they have the same width, the opening half-angle of the "V" of the support 32 is reduced. The lower surface 152 is crenellated with a pitch identical to that of the intermediate supports. The junction support 32 has side edges 153 and 154, connecting the top 150 and bottom surfaces 152, and end cross faces 155 and 156. The junction support 32 has a reduced length.
    [0017] The upper surface 150 is provided with a central groove 160 and a groove 170 at the bottom of the groove 160. In this embodiment, the dimensions of the groove 170 are such that it defines a cavity inside. of the connecting element 32. Each transverse end face 155, 156 respectively of the junction support 32 is provided with a circular orifice 157, 158 respectively, opening into the groove 170. The axis of the orifice 157, 158, is slightly inclined with respect to the axis X, an angle e. This orifice is intended to receive the end of a supply tube 27 of the low-voltage power supply 28 and antenna 29 as shown in FIG. 9. The low-voltage supply cable is therefore introduced into the support at a junction support 32, and then flows from the junction support, through the groove 70 intermediate end and central supports to finally be connected to the conductive segment of the track. Each end wall 155, 156, of the junction support 32 has a notch whose contour corresponds to the cross section of the duct 70 of a neighboring intermediate support. This notch makes it possible to pass the power supply cable from the cavity of the connection support 32 directly into the duct 70 of the adjacent intermediate support 34. Each lateral edge 153, 154 is provided with through-holes 183, 184, allowing the fixing junction support directly into the concrete base 22, by means of studs. Each side edge is provided with an antenna channel 185, respectively 186. However, the antenna channel 185, 186 forms an angle substantially at 45 ° with respect to the median plane XZ so as to connect a transverse face of end 155 or 156 to a side wall 173 or 173 of the conduit 170. An antenna cable forms a loop associated with a support section 30. Thus, the antenna cable introduced into the support 24 at a first support junction 32, flows in the channel 185 of the first junction support, in the channel 83 of the intermediate supports defining the support section 30, and in the channel 183 of a second junction support; then back flowing in a channel 184 of the second junction support, in the channel 84 of the intermediate supports defining the support section 30, then in the channel 184 of the first junction support to return to the groove 170 thereof. The antenna cable thus forms an induction loop for detecting the presence of a tramway directly above the support section 30. This makes it possible to control the power substation of the driver segment associated with this section of the support at the time of the passage of a tram. In Figure 10 is shown a connecting sheet 38 between two consecutive intermediate supports 36 and 34. The sheet 38 is flexible and thin. It is made of an elastomeric material. It serves as a barrier preventing any electrical leaks in the ground. The sheet 38 is shaped to have a conjugate upper face of the lower surface 52 of the intermediate supports to be connected. In particular, the upper surface of the sheet 38 has crenellations complementary to those of the ends of the intermediate supports to be connected. Each intermediate support is fixed by gluing to the sheet 38. The notches of the central crenel of the upper surface of the sheet bear respectively on a redan of the end slot of a support and on the redan of the end slot of the other support, so as to apply them longitudinally against each other. The method of implantation 100 of a ground supply system in a roadway will now be presented with the aid of FIG. 11. In a step 105, carried out beforehand in the factory, a track support section 30 is made by combining the various intermediate supports 34 and 36 by means of joining sheets 38. Each sheet 38 is glued to the ends of two adjacent intermediate supports. The section 30 thus produced is sourced on site. In a step 110, a trench is cleared on the roadway 12. In the next step 120, to level the bottom of the trench, a concrete slab is poured. The track slab and the bearing rails are positioned on this raft in the case of a railway system. Then, at step 130, by means of a template specifically adapted for this purpose, the section of the support 30 is pre-assembled. positioned above the slab. It should be noted that during the pre-positioning of a support, the template is adapted to apply a suitable force for bending the support so as to confer a radius of curvature corresponding to a required profile. The template also allows precise positioning of the support along the X, Y and Z axes and suitable for exerting an appropriate force to withstand the pressure of the concrete or the material used to make the base.
    [0018] In a sub-step 132, the first junction support is positioned. The section 30 is placed in continuity with the end of the support section. In a sub-step 134, the feed tube of the antenna and power supply cables is pulled to and connected to the first connection support. The power cable is passed through the first junction support, into the groove of the intermediate supports of the section 30, and then pulled so that its end reaches the point of connection to the conductive segment. The antenna cable is passed, through the first junction support, the intermediate supports and the second junction support of the section 30, then, on return, through the second junction support, the supports intermediate of the section 30 and the first junction support, so as to form a loop. It should be noted that dowels are prepositioned on the lower surface 52 and 152 of the supports, in continuity with the through holes 83, 84, 183, 184. Then, in step 140, a suitable concrete is poured between the floor and the supports so as to form the base 22 for holding the support in the roadway. The concrete is poured into a formwork (fixed or sliding), until it reaches either the level of the upper surface of the supports or the low level of the edges 53, 54, 153, 154. The prepositioning of the supports allows, when the concrete is poured, to reserve by molding a recess in the base 22. This recess has a shape complementary to that of the lower surface 52, 152 supports, possibly bent.
    [0019] Once the concrete is taken, in step 150, studs are screwed through the through holes of the supports. These studs engage the anchors now anchored in the concrete base 22. The pressure of the stud on the shoulder of a through hole allows the attachment of the support on the base. In step 160, the track is performed. In a sub-step 162, the end of the low voltage power supply cable flowing in the groove of the supports is mechanically and electrically connected to the conductive segment. In a sub-step 164, the segments are placed in the grooves of the supports and then fixed by bolting. The process is then iterated for the next section.
    [0020] In a variant, the operation of pulling and connecting the cables, the power supply or the antenna, is carried out, not at each iteration, but after the installation of the supports before the positioning of the segments forming the track. Those skilled in the art will find that the maintenance of such a power supply system by the ground is extremely simple.
    [0021] If it is a question of replacing a damaged track segment, simply unscrew the bolts of the segment to be replaced, then remove it from the throat. Since the segment is not glued to the support, disconnecting the segment does not damage the support. This can therefore receive a replacement segment, which is fixed on the support, in place of the damaged segment, as indicated above in the corresponding step of the implantation process. If it is a question of replacing a damaged support, it is enough to unscrew the corresponding dowels to separate the support of the base. The support is then disengaged by force of the recess in the form of a cradle made in the base. Then a new support is put in place. The crenellated form of the bottom surface of a support being standard, the replacement support is received in the recess of the base. When the damaged support has a radius of curvature, the replacement support is deformed transversely in order to force it into the recess made so as to conform to the radius of curvature of the recess. Once the replacement medium inserted in the recess, the latter constrains the support so that the support retains the radius of curvature that has been conferred. The studs are then put back in place to secure the support to the base. The track segments are then put back in place. In the present application, land vehicle means any vehicle contributing to land transport, guided on tires or on iron, of passengers or freight.
    [0022] In particular, land-based transport guided on iron, all rail-type transport, urban type, for example tram, suburban type, for example metro, suburban type, regional type or high speed type, very high speeds. In ground guided transport, on the other hand, any ground transportation using tires, for example of the pneumatic subway, pneumatic tramway type, or any type of ground transportation associated with electrical roads of the electric bus, electric truck or electric car type.
