Abstract

The method of containing bitumen around a tramway rail involves placing a cover formed by two steel side plates (16) connected by at least one cross spacer (17) which engages on the rail. The cover is fixed in place and its lower section placed in an intermediate layer (27). A rolled layer (30) in placed on the intermediate layer up to the top of the frame. The spacer is then removed and a sealing material poured into place.

Description

La présente invention est relative à un procédé de confinement d'enrobés bitumineux au voisinage d'un rail fixé sur un socle et muni de chaque côté d'unE bordure et d'un joint d'étanchéité souple anti-vibrations.The present invention relates to a method of confinement of bituminous mixes in the vicinity of a fixed rail on a base and provided on each side with a border and a flexible anti-vibration seal.

L'invention s'applique en particulier à la réalisation des voies de circulation routières au voisinage des rails de tramways. On entend ici par « tramway » tout véhicule guidé par au moins un rail, qu'il s'agisse d'un véhicule purement ferroviaire, dont les roues circulent sur des rails généralement munis à leur sommet d'une gorge de guidage, ou d'un véhicule sur pneus guidé par un rail central.The invention applies in particular to the construction of road traffic lanes in the vicinity tram rails. “Tram” means here everything vehicle guided by at least one rail, whether it is a purely railway vehicle, the wheels of which run on rails generally provided at their top with a groove of guidance, or of a vehicle on tires guided by a rail central.

L'invention a pour but de permettre l'obtention, dans toutes les configurations de rails, d'une couche de roulement dont le bord adjacent aux rails est franc et situé à un niveau précis par rapport au sommet du rail.The object of the invention is to enable the obtaining, in all rail configurations, a layer of bearing whose edge adjacent to the rails is straight and located at a precise level in relation to the top of the rail.

A cet effet, l'invention a pour objet un procédé caractérisé par la succession d'étapes suivantes :

  • (a) on pose sur le rail une coiffe comprenant deux fers plats latéraux reliés par au moins une entretoise transversale qui prend appui sur le rail ;
  • (b) on fixe la position des fers plats et on en incorpore la partie inférieure dans une couche intermédiaire ;
  • (c) on met en oeuvre sur la couche intermédiaire, jusqu'à un niveau prédéterminé par rapport au bord supérieur des fers plats, une couche de roulement ;
  • (d) on retire l'entretoise ; et
  • (e) on met en place de chaque côté le joint d'étanchéité, notamment par coulée.
    • To this end, the subject of the invention is a process characterized by the following sequence of steps:
  • (A) a cap is placed on the rail comprising two lateral flat bars connected by at least one transverse spacer which bears on the rail;
  • (b) fixing the position of the flat irons and incorporating the lower part thereof into an intermediate layer;
  • (c) a wearing course is applied to the intermediate layer, up to a predetermined level relative to the upper edge of the flat bars;
  • (d) removing the spacer; and
  • (E) the seal is placed on each side, in particular by casting.

    • L'invention a également pour objet un dispositif destiné à la mise en oeuvre du procédé tel que défini ci-dessus. Ce dispositif est caractérisé en ce qu'il comprend une coiffe constituée de deux fers plats sensiblement parallèles dont les bords supérieurs sont reliés par au moins une entretoise transversale.The invention also relates to a device intended for the implementation of the method as defined above. This device is characterized in that it comprises a cap consisting of two substantially flat irons parallel whose upper edges are connected by the minus a transverse spacer.

    Les Figures 1 à 7 illustrent la réalisation d'une voie de tramway sur pneus guidée par un rail central 1. Le rail est constitué d'un pied 2, d'une âme 3 et d'une tête 4 dont la face supérieure 5 est sensiblement plane et horizontale, légèrement bombée dans cet exemple. La voie est symétrique par rapport au plan vertical de symétrie P du rail. Figures 1 to 7 illustrate the realization of a tramway track on tires guided by a central rail 1. The rail consists of a foot 2, a core 3 and a head 4 whose upper face 5 is substantially flat and horizontal, slightly domed in this example. The way is symmetrical with respect to the vertical plane of symmetry P of the rail.

    Le pied 2 est posé sur un socle ou longrine 6 en béton de ciment, flanqué de chaque côté d'une sous-couche 7 en béton bitumineux à module élevé (BBME), par exemple celui commercialisé sous la marque « COMPOMODULE ». La face supérieure de la sous-couche 7 est au même niveau que celle du socle 6.The foot 2 is placed on a base or sill 6 in cement concrete, flanked on either side of an underlay 7 high modulus bituminous concrete (BBME), for example that marketed under the brand name "COMPOMODULE". The face of the underlay 7 is at the same level as that from the base 6.

    A intervalles réguliers, le rail 1 est fixé en place par des dispositifs de calage appropriés 8.At regular intervals, the rail 1 is fixed in place by suitable wedging devices 8.

    L'étape suivante (Figure 2) consiste en la pose, de part et d'autre du rail, d'une bordure rigide 9 en béton de ciment, fixée au socle 6 par collage au moyen d'une couche 10 d'un adhésif approprié. Le positionnement de chaque bordure 9 est assuré par une ou plusieurs cale(s) 11 interposée(s) entre la tête du rail et la face latérale adjacente de la bordure.The next step (Figure 2) consists of laying, on either side of the rail, a rigid edge 9 of concrete cement, fixed to the base 6 by bonding by means of a layer 10 with a suitable adhesive. The positioning of each border 9 is provided by one or more wedges 11 interposed between the head of the rail and the side face adjacent to the border.

    La face latérale intérieure de chaque bordure est munie à sa base d'évidements 12 qui reçoivent les dispositifs 8 de calage du rail. La face latérale extérieure 13 de chaque bordure est coplanaire à la face latérale correspondante du socle, et les faces supérieures 14 des deux bordures, qui constituent les voies de roulement des pneus du tramway, sont au niveau du point haut le plus élevé O du rail, situé dans le plan P. Ceci est facile à obtenir avec une précision élevée, car les bordures et le socle sont des éléments en béton de ciment.The inner side of each border is provided at its base with recesses 12 which receive the rail wedging devices 8. The outer side face 13 of each border is coplanar with the lateral face corresponding to the base, and the upper faces 14 of two edges, which constitute the tracks of the tram tires are at the highest point O of the rail, located in plane P. This is easy to obtain with high precision, because the edges and the base are cement concrete elements.

    Pour obtenir une précision analogue, typiquement de l'ordre de 1 mm, sur le niveau supérieur des voies de circulation routière adjacentes en béton bitumineux, on procède de la manière suivante.To obtain similar precision, typically from around 1 mm, on the upper level of the adjacent asphalt concrete road traffic, proceed as follows.

    On utilise une coiffe 15, représentée sur la Figure 3, constituée de deux fers plats verticaux et parallèles 16 reliés par soudage à des feuillards horizontaux et transversaux 17 rigides formant entretoises. Les tranches d'extrémité 18 de ces entretoises se trouvent dans les plans des faces extérieures 19 des fers plats.We use a cap 15, shown in Figure 3, consisting of two vertical and parallel flat bars 16 welded to horizontal strips and transverse 17 rigid forming spacers. The slices end 18 of these spacers are in the plans outer faces 19 of flat irons.

    Comme représenté sur la Figure 4, la coiffe 15 est posée sur l'ensemble constitué du rail, des deux bordures 9 et des deux cales 11. Le dimensionnement est tel que chaque fer plat est juxtaposé, avec un jeu latéral, à la face latérale extérieure de la bordure adjacente. Le milieu de chaque entretoise 17 s'appuie au sommet O du rail, tandis que ses parties latérales s'appuient sur la face supérieure 14 des deux bordures.As shown in Figure 4, the cap 15 is placed on the assembly consisting of the rail, the two edges 9 and two wedges 11. The dimensioning is such that each flat iron is juxtaposed, with lateral play, on the face lateral exterior of the adjacent border. The middle of each spacer 17 is supported at the top O of the rail, while that its lateral parts rest on the upper face 14 of the two borders.

    Une plaque d'amortissement de vibrations 20 en élastomère emplit l'espace compris entre chaque fer plat et la bordure adjacente. Cette plaque part du niveau supérieur du socle 6 ou de la sous-couche 7 et s'étend vers le haut presque jusqu'aux entretoises 17. Elle comporte dans sa partie supérieure, en regard du fer plat, une ligne de déchirure longitudinale 22, par exemple une encoche latérale.A vibration damping plate 20 in elastomer fills the space between each flat iron and the adjacent border. This plate starts from the upper level the base 6 or the underlay 7 and extends upwards almost to the spacers 17. It has in its upper part, opposite the flat iron, a line of longitudinal tear 22, for example a notch lateral.

    De cette manière, le bord supérieur 21 de chaque fer plat se trouve exactement au niveau du point 0, et les fers plats sont positionnés avec précision dans le sens latéral.In this way, the upper edge 21 of each iron flat is exactly at point 0, and the irons dishes are precisely positioned in the lateral direction.

    On fixe alors la position des fers plats au moyen d'un certain nombre d'équerres métalliques 23, dont une seule est représentée sur la Figure 3. La branche verticale 24 de chaque équerre est accolée à la face 19 du fer plat et soudée sur celle-ci, tandis que sa base 25 est fixée à la sous-couche 7 par « spittage », c'est-à-dire par mise en place de clous 26 au moyen d'un pistolet.The position of the flat irons is then fixed by means of a number of metal brackets 23, one of which only one is shown in Figure 3. The vertical branch 24 of each bracket is attached to the face 19 of the flat iron and welded to it, while its base 25 is fixed to the sublayer 7 by "spittage", that is to say by setting place nails 26 by means of a pistol.

    L'ensemble ainsi réalisé est représenté en perspective sur la Figure 5, où les équerres sont espacées sensiblement de la même manière que les entretoises 17.The assembly thus produced is represented in perspective in Figure 5, where the brackets are spaced substantially in the same manner as the spacers 17.

    L'étape suivante consiste à mettre en oeuvre sur la sous-couche 7 une couche intermédiaire 27 en béton bitumineux à module élevé, de composition analogue à celle de la sous-couche, jusqu'à un niveau légèrement supérieur à celui de l'extrémité supérieure des équerres 23.The next step is to implement on the underlay 7 an intermediate layer 27 of concrete high modulus bituminous, similar in composition to that of the underlay, to a level slightly higher than that of the upper end of the brackets 23.

    Ainsi, ces équerres sont entièrement incorporées dans la couche 27, de même que la partie inférieure des faces latérales 19 des fers plats. Au-dessous de ces derniers, la couche 27 prend appui latéralement sur la plaque en élastomère 20.So these brackets are fully incorporated in layer 27, as well as the lower part of lateral faces 19 of flat irons. Below these last, layer 27 is supported laterally on the elastomer plate 20.

    Ensuite, on pose sur la sous-couche 27 une structure alvéolaire métallique semi-rigide 28. Cette structure, en tôle d'acier, est telle que décrite dans le FR-A-2 640 297 de la Demanderesse et est commercialisée sous la marque « METALFLEX ». Elle peut notamment avoir une structure en nid d'abeille avec chaque tôle disposée verticalement, comme représenté sur la Figure 7. Les bords d'extrémité de la structure 28 peuvent être soudées aux faces 19 des fers plats, comme indiqué en 29. Eventuellement, la structure 28 peut être fixée par spittage sur la couche 27, grâce à des pattes perforées prévues à sa partie inférieure.Next, a structure is placed on the underlay 27 semi-rigid metallic honeycomb 28. This structure, in sheet steel, is as described in FR-A-2 640 297 from the Applicant and is marketed under the brand "METALFLEX". It can in particular have a structure in honeycomb with each sheet arranged vertically, as shown in Figure 7. The end edges of the structure 28 can be welded to the faces 19 of the irons flat, as indicated in 29. Optionally, the structure 28 can be fixed by spitting on layer 27, thanks to perforated legs provided at its lower part.

    Ensuite, on met en oeuvre sur la couche 27 une couche de roulement 30 en enrobés bitumineux à module élevé, de composition analogue à celle de la couche 27, jusqu'à un niveau situé légèrement au-dessous du niveau supérieur des fers plats 16.Then, a layer 27 is implemented wearing course 30 in high modulus bituminous mixes, of composition similar to that of layer 27, up to a level located slightly below the upper level of flat irons 16.

    La couche 30 incorpore totalement la structure 28, et, comme elle est compactée contre la face 19 parfaitement plane et rigide d'un fer plat, elle peut être réalisée avec une arête 31 très nette et avec un niveau réglé de façon très précise par rapport au bord supérieur du fer plat, et donc par rapport au sommet O du rail.The layer 30 fully incorporates the structure 28, and, as it is compacted against the face 19 perfectly flat and rigid with a flat iron, it can be made with a very sharp edge 31 and with a level adjusted so very precise with respect to the upper edge of the flat iron, and so compared to the top O of the rail.

    Ensuite, on retire les entretoises 17 par meulage, on élimine la partie supérieure des plaques 20, jusqu'à l'encoche 22, et on coule dans l'espace ainsi libéré un joint d'étanchéité souple 32 anti-vibrations en une matière appropriée, notamment en polyuréthane. Then, the spacers 17 are removed by grinding, the upper part of the plates 20 is eliminated, up to the notch 22, and one flows into the space thus freed a flexible anti-vibration seal 32 made of a material suitable, especially in polyurethane.

    Après enlèvement des cales 11, l'ensemble de la voie est tel que représenté sur la Figure 8. En cours d'utilisation, on constate que l'arête 31 ne se détériore pas, et qu'il n'y a pas de tendance à la fissuration de la couche de roulement 30 au voisinage des fers plats.After removal of wedges 11, the entire track is as shown in Figure 8. In progress of use, it is noted that the edge 31 does not deteriorate not, and that there is no tendency to crack the wearing course 30 in the vicinity of the flat bars.

    La variante de la Figure 9 est destinée à la réalisation de voies de tramways ferroviaires dont les roues circulent sur deux rails 1 munis chacun d'une gorge longitudinale de guidage G dans leur surface supérieure.The variant of Figure 9 is intended for the construction of railway tramways including wheels run on two rails 1 each provided with a groove longitudinal guide G in their upper surface.

    Contrairement à ce qui a été décrit précédemment, la voie ne comporte pas de bordure rigide 9, mais deux éclisses 109 semi-rigides disposées de part et d'autre du rail, directement contre celui-ci, et épousant la forme du pied, de l'âme et de la tête du rail. Dans le sens vertical, les éclisses 109 s'étendent de la surface supérieure du pied 2 jusqu'à un niveau intermédiaire de la tête 4 du rail. Les éclisses sont par exemple constituées d'une mousse de polyuréthane ayant une densité de 100 kg/m3.Contrary to what has been described above, the track does not have a rigid edge 9, but two semi-rigid ribs 109 arranged on either side of the rail, directly against the latter, and conforming to the shape of the foot, the soul and head of the rail. In the vertical direction, the ribs 109 extend from the upper surface of the foot 2 to an intermediate level of the head 4 of the rail. The fishplates are for example made of a polyurethane foam having a density of 100 kg / m 3 .

    La réalisation de la voie utilise la coiffe 15, les équerres 23 et les structures 28 précédemment décrites, mais d'une manière légèrement différente, qui va maintenant être décrite.The realization of the track uses the cap 15, the brackets 23 and the structures 28 previously described, but in a slightly different way, which is now going to be described.

    Le rail 1 étant mis en place sur le socle 6 en béton de ciment, éventuellement avec interposition d'une rehausse 33, les deux éclisses sont mises en place de part et d'autre du rail, puis la coiffe 15 est mise en place. Le dimensionnement est tel que les fers plats 16 encadrent les deux éclisses, au contact direct de celles-ci.The rail 1 being placed on the concrete base 6 of cement, possibly with the interposition of an extension 33, the two fishplates are placed on both sides of the rail, then the cap 15 is put in place. The dimensioning is such that the flat irons 16 frame the two fishplates, in direct contact with them.

    Ce faisant, les entretoises 17 prennent appui sur le point O le plus élevé du rail, qui est dans ce cas décalé par rapport au plan longitudinal médian de l'âme 3.In doing so, the spacers 17 are supported on the highest point O of the rail, which in this case is offset relative to the median longitudinal plane of the core 3.

    Ensuite, la position des deux fers plats est fixée au moyen des équerres 23, comme précédemment, puis on enrobe ces dernières dans la couche intermédiaire 27. Then the position of the two flat irons is fixed by means of the brackets 23, as above, then we coat the latter in the intermediate layer 27.

    Ensuite, la structure 28 formant armature semi-rigide est posée sur la couche 27 et fixée par soudage aux fers plats 16 et à la couche 27, et la couche de roulement 30 est mise en oeuvre.Next, the structure 28 forming a semi-rigid frame is laid on layer 27 and fixed by welding to flat bars 16 and layer 27, and the wearing course 30 is implemented.

    Enfin, les entretoises 17 sont éliminées par meulage, et les joints d'étanchéité souples anti-vibrations 32 sont coulés dans les espaces délimités par la face intérieure des fers plats, la face supérieure des éclisses 109 et le bord latéral de la tête de rail 4.Finally, the spacers 17 are eliminated by grinding, and flexible anti-vibration seals 32 are poured into the spaces delimited by the face interior of flat irons, upper side of fishplates 109 and the side edge of the rail head 4.

    Il est à noter que lorsque, comme décrit plus haut, les structures 28 sont fixées aux fers plats 16, l'utilisation des équerres 23 peut devenir superflue. Dans ce cas, les étapes sont successivement, par exemple dans la variante de la Figure 9 : pose de la coiffe 15; mise en oeuvre de la couche 27 ; pose et fixation des structures 28 ; mise en oeuvre de la couche de roulement 30 ; enlèvement des entretoises 17 ; mise en place des joints 32.It should be noted that when, as described above, the structures 28 are fixed to the flat bars 16, the use of brackets 23 may become superfluous. In this case the steps are successively, for example in the variant of Figure 9: fitting the cap 15; setting artwork from layer 27; laying and fixing of structures 28; implementation of the wearing course 30; removal of the spacers 17; installation of seals 32.
