Abstract

The module (1) has a transversal connection unit (3) connecting support elements i.e. longitudinal beams. Jambs of the unit are extended between troughs (2) such that a transversal space is formed with an opening connected between volumes defined at top and below of the module. Bases of the troughs and the jambs are arranged in a same plane. Two axial end faces of the troughs at a same axial end of the module are vertical and in a same plane when the modules are coupled together in alignment, so that the discontinuity is avoided between inner side faces (21) of channels (20) of the troughs. An independent claim is also included for a method for assembling a railway turfed on a grass surface.

Description

La présente invention concerne un module préfabriqué support de voie ferrée, une voie ferrée comportant de tels modules, une section préfabriquée de voie ferrée ainsi qu'un procédé de montage d'une telle voie ferrée. Elle a des applications dans le domaine du génie civil et plus particulièrement pour la construction de voies ferrées engazonnées en surface, notamment pour des réseaux urbains de tramway.The present invention relates to a prefabricated rail support module, a railway track comprising such modules, a prefabricated railway section and a method for mounting such a railroad track. It has applications in the field of civil engineering and more particularly for the construction of turfed railroad tracks, especially for urban tramway networks.

Les réseaux de tramways urbains connaissent à nouveau un certain regain d'intérêt dans les espaces urbains. Ils nécessitent cependant la réalisation d'une infrastructure relativement lourde par rapport à d'autres systèmes plus légers comme le trolleybus car ils nécessitent la construction d'une voie ferrée spécifique pour y circuler. Dans ces environnements urbains, la présence d'une voie ferrée nue, bien qu'elle ne nécessite pas un entretien très fréquent, n'est pas toujours apprécié du point de vue esthétique. On a donc été conduit à camoufler ces voies ferrées par un engazonnement de surface. Or, du fait des modes de construction des ces voies ferrées, des dalles de béton sont réalisées sous la voie. Il en résulte un compartimentage en hauteur de la voie ferrée et la partie haute de la voie qui est engazonnée se retrouve isolée du terrain naturel ou préparée sur lequel repose la voie. Il est donc nécessaire de prévoir des moyens d'évacuation de l'eau, notamment de pluie ou d'arrosage, sous forme de moyens de drainage adéquats, pour éviter sa stagnation. De plus, du fait de la faible hauteur disponible sur la voie pour l'engazonnement, la quantité de substrat pour la culture du gazon est relativement faible. L'entretien du gazon est donc relativement complexe notamment en ce qui concerne l'obtention d'un niveau d'humidité suffisant et suffisamment stable au cours du temps dans le substrat. Il en résulte un plus grand risque de voir le gazon soumis à des stress environnementaux pouvant conduire à sa perte.Urban tramway networks are once again enjoying renewed interest in urban spaces. However, they require the construction of a relatively heavy infrastructure compared to other lighter systems such as the trolleybus because they require the construction of a specific railway to circulate. In these urban environments, the presence of a bare railway, although it does not require frequent maintenance, is not always appreciated from an aesthetic point of view. So we have been led to hide these railways by a sod surface. However, because of the construction methods of these railways, concrete slabs are made under the track. This results in a subdivision of the railway at a height and the upper part of the track which is sodded is isolated from the natural or prepared ground on which the track rests. It is therefore necessary to provide means for evacuation of water, including rain or watering, in the form of adequate drainage means to prevent stagnation. In addition, because of the low height available on the track for sodding, the amount of substrate for growing turf is relatively small. The care of the lawn is therefore relatively complex, particularly with regard to obtaining a sufficient level of humidity and sufficiently stable over time in the substrate. This results in a greater risk of turf being subjected to environmental stresses that could lead to its loss.

Un des buts de la présente invention parmi d'autres est de proposer un moyen de réaliser une voie ferrée qui, dans le cas d'un engazonnement de surface, assure des conditions de développement plus naturelles au gazon en évitant le compartimentage en hauteur de ladite voie ferrée et en permettant au substrat engazonné de surface de pouvoir venir au contact du sol sous la voie ferrée. D'autres buts et avantages apparaîtront à la lecture de la suite de ce document.One of the aims of the present invention among others is to propose a means of making a railroad which, in the case of a surface turf, ensures more natural development conditions for the turf by avoiding subdivision of said track and allowing the surface grassed substrate to come into contact with the ground under the railway. Other goals and benefits will become apparent from the rest of this document.

Ainsi, l'invention concerne un module support de voie ferrée, le module comportant latéralement par rapport à l'axe central de la voie, deux éléments de support des deux rails de la voie et, dans l'espace transversal entre les deux éléments de support, un moyen de liaison transversal les reliant, l'élément de support étant destiné à recevoir une longrine de béton armé comportant des tiges filetées et sur laquelle sont posées des selles d'ancrage soutenant le rail par boulonnage de patins sur les tiges filetées qui traversent verticalement les selles, ledit module permettant un engazonnement en surface de la voie ferrée.Thus, the invention relates to a railway track support module, the module having laterally with respect to the central axis of the track, two support elements of the two rails of the track and, in the transverse space between the two elements of the track. support, a transverse connection means connecting them, the support element being intended to receive a reinforced concrete sill having threaded rods and on which are placed anchoring saddles supporting the rail by bolting pads on the threaded rods which vertically pass through the saddles, said module allowing sodation on the surface of the railway.

L'invention concerne également une section préfabriquée de voie ferrée à deux rails, de longueur déterminée, telle qu'elle comporte un ensemble de modules selon l'une ou plusieurs des caractéristiques décrites, lesdits modules étant alignés et accolés ensembles, deux longrines en béton armées réalisées par coulage de béton dans les canaux alignés des augets, lesdites longrines comportant en outre des tiges filetées, des selles d'ancrage et patins étant disposés sur les longrines, les rails étant disposés sur les selles et étant maintenus par boulonnage des patins sur les tiges filetées.The invention also relates to a prefabricated railway section with two rails, of predetermined length, such that it comprises a set of modules according to one or more of the described features, said modules being aligned and joined together, two reinforced concrete sills made by pouring concrete into the aligned channels of the buckets, said sills further comprising threaded rods, anchor saddles and pads being arranged on the stringers, the rails being disposed on the saddles and being held by bolting the pads on the threaded rods.

L'invention concerne également un procédé de réalisation d'une voie ferrée à deux rails, engazonnée en surface, tel que :

  • on installe un ferraillage dans les canaux des augets des modules,
  • on installe des tiges filetées, selles, patins et rails,
  • on positionne les rails le long des canaux alignés des augets,

  • la préparation du sol consiste à obtenir une surface portante ayant des caractéristiques de drainage déterminées, par exemple en mettant en oeuvre des matériaux et/ou des équipements adaptés.
In possibly combined variants, the process is such that:

  • for installation and positioning of the rails, a spacing and alignment gauge of the rails is implemented,
  • the template is a rigid organ,

  • the preparation of the soil consists in obtaining a bearing surface having determined drainage characteristics, for example by using suitable materials and / or equipment.

L'utilisation de modules préfabriqués servant à constituer des longrines porteuses de la voie ferrée, permet de préserver entre chaque rails et entre chaque voies des contacts terre (sol sur lequel repose la voie)/terre (substrat engazonné de surface) qui permettent un allègement de la structure et une meilleure tenue des gazons fondés sur un substrat recevant les échanges hygrométriques. De plus, parmi les avantages de l'utilisation des modules préfabriqués, autres que ceux liés aux bénéfices pour le développement du gazon et son entretien sur une voie ferrée engazonnée, on peut citer à titre d'exemple les suivants.The use of prefabricated modules used to build rails carrying the railway, makes it possible to preserve between each track and between each track earth (ground on which the track is based) / ground (surface grassed substrate) contacts which allow a lightening of the structure and a better hold of the turf based on a substrate receiving the hygrometric exchanges. In addition, among the advantages of using prefabricated modules, other than those related to the benefits for grass development and its maintenance on a grassed railway, the following can be cited as examples.

L'invention, par utilisation de modules préfabriqués simplifie la réalisation des voies ferrées en milieu urbain où l'on connaît les inconvénients d'une emprise trop importante et/ou longue sur le domaine urbain. Les modules sont relativement simples à réaliser par moulage de béton dans un/des moules contenant un ferraillage.The invention, by using prefabricated modules simplifies the realization of railways in urban areas where we know the disadvantages of a footprint too important and / or long on the urban domain. The modules are relatively simple to achieve by molding concrete in a molds containing a reinforcement.

Elle permet également de limiter les travaux à réaliser et les délais d'obtention d'une voie ferrée utilisable puisque l'on évite d'avoir à réaliser une ou plusieurs dalles de béton in situ pour supporter la voie ferrée. De plus, par la mise en oeuvre de modules servant par les canaux de leurs augets de réceptacle à un coulage de béton fluide pour réalisation de longrines, on met en oeuvre une technique qui s'apparente au coffrage perdu et, ainsi, le béton est coulé le long de la voie seulement là où il est nécessaire (les longrines) et, ceci, en faible quantité par rapport à la technique traditionnelle. La voie réalisée est également allégée par rapport à la technique traditionnelle.It also makes it possible to limit the work to be carried out and the time required to obtain a usable railway since it is avoided to have to make one or more concrete slabs in situ to support the railway. In addition, by the implementation of modules used by the channels of their receptacle buckets to a pouring of fluid concrete for the production of longitudinal members, a technique is used that is similar to the lost formwork and, thus, the concrete is poured along the track only where it is needed (the stringers) and this, in small quantities compared to the traditional technique. The route is also lightened compared to the traditional technique.

L'invention modifie également les modalités d'écoulement de l'eau au sein de la voie ferrée. Ainsi, outre l'intérêt du module pour la réalisation de voies ferrées engazonnées, la présence d'ouvertures de communications entre les deux faces/espaces supérieur et inférieur du module peut également être utile dans le cas où le sol est naturellement drainant car l'eau, par exemple de pluie, arrivant par le dessus de la voie ferrée, peut traverser cette dernière et atteindre le sol où elle est évacuée, contrairement aux dispositifs traditionnels dans lesquels il existe une barrière s'opposant à l'écoulement de l'eau à travers la voie ferrée (due par exemple à la mise en oeuvre d'un radier en béton ou d'éléments de support et fixation des rails continus sans communication) et où il est alors nécessaire de prévoir un drainage spécifique.The invention also modifies the flow of water in the railway. Thus, in addition to the interest of the module for the realization of turfed railroad tracks, the presence of communication openings between the two faces / upper and lower spaces of the module can also be useful in the case where the soil is naturally draining because the water, for example rain, arriving from above the railway, can cross the latter and reach the ground where it is evacuated, unlike traditional devices in which there is a barrier opposing the flow of water through the railway (due for example to the implementation of a concrete slab or elements supporting and fixing the continuous rails without communication) and where it is then necessary to provide a specific drainage.

The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • The figure 1 is an axial view (along the axis of the path, therefore), of a cross section of a module according to the invention,
  • The figure 2 is a top view of the module,
  • The figure 3 is a lateral view (transverse / perpendicular to the axis of the track, therefore), of an axial section of the module,
  • The figure 4 is an axial view, a cross section of a double track made with the modules of the invention,
  • The figure 5 is a top view of a railway constituted by the assembly of modules juxtaposed and in alignment,
  • The figure 6 is an axial view, in transverse section, of a trough of the module of a track mounted with its rail, in the case of a sill obtained by pouring a fluid concrete, and
  • The figure 7 is an axial view, in transverse section, of a trough of the module of a track mounted with its rail, in the case of a sill comprising a blocket held by a setting concrete.

Sur les Figures 1 à 3, le module 1 de support de rails de voie ferrée qui est un élément monobloc en béton armé (les fers sont schématisés en pointillés épais sur la Figure 1) préfabriqué, comporte latéralement par rapport à l'axe central de la voie deux éléments appelés augets 2 pour support et fixation des deux rails de la voie et dans l'espace transversal entre les deux augets un moyen de liaison transversal 3 reliant les deux augets 2.On the Figures 1 to 3 , the railway track support module 1 which is a reinforced concrete monobloc element (the irons are schematically dotted thick on the Figure 1 ) prefabricated, comprises laterally with respect to the central axis of the track two elements called buckets 2 for support and fixing of the two rails of the track and in the transverse space between the two buckets a transverse connection means 3 connecting the two buckets 2.

L'auget 2 est en forme de canal 20 ouvert vers le haut et latéralement à ses deux extrémités axiales (dans la longueur du rail de la voie). Le canal 20 de l'auget 2 est donc limité latéralement par deux faces internes latérales 21 et un fond 22. Dans cet exemple de réalisation, les deux faces internes latérales 21 du canal de l'auget sont inclinées pour réaliser une forme globale de canal d'auget en queue d'aronde en vue axiale, le fond 22 du canal de l'auget étant plus large que l'ouverture supérieure vers le haut du canal 20 de l'auget 2. Cette forme en queue d'aronde assure une meilleure tenue à l'arrachement de la longrine qui est réalisée dans le canal 20. Dans une variante, les deux faces internes latérales 21 du canal de l'auget sont verticales. L'auget comporte en outre des orifices 4 (diamètre approximatif 40 mm) destinées à permettre la prise du module pour sa manipulation.The trough 2 is channel-shaped 20 open upwardly and laterally at its two axial ends (in the length of the rail of the track). The channel 20 of the bucket 2 is thus limited laterally by two lateral internal faces 21 and a bottom 22. In this embodiment, the two lateral internal faces 21 of the bucket channel are inclined to form a global channel shape. bucket dovetail in axial view, the bottom 22 of the channel of the bucket being wider than the upper opening up the channel 20 of the bucket 2. This form dovetail provides a better resistance to tearing of the sill which is made in the channel 20. In a variant, the two lateral internal faces 21 of the channel of the bucket are vertical. The bucket further comprises orifices 4 (approximately 40 mm diameter) designed to allow the module to be gripped for handling.

Dans cet exemple de réalisation, la forme générale du gabarit externe de l'auget 2 en vue axiale (Figure 1) est sensiblement pyramidale tronquée, les faces externes latérales 23 de l'auget étant sensiblement inclinées (sauf en partie basse coté central du module sur la Figure 1). Dans une variante la forme générale est parallélépipédique, les faces externes latérales 23 étant verticales. La forme générale externe du module 1 en vue de dessus (Figure 2) est globalement rectangulaire et est plus particulièrement adaptée à une voie linéaire droite, les modules s'accolant parfaitement entre eux le long de la voie. On verra plus loin que des formes à bords axiaux non parallèles sont possibles pour des voies courbes.In this embodiment, the general shape of the external jig of the bucket 2 in axial view ( Figure 1 ) is substantially pyramidal truncated, the external lateral faces 23 of the bucket being substantially inclined (except in the lower part of the central part of the module on the Figure 1 ). In one variant, the general shape is parallelepipedal, the lateral external faces 23 being vertical. The general external shape of module 1 in top view ( Figure 2 ) is generally rectangular and is more particularly adapted to a straight linear path, the modules perfectly fitting together along the path. It will be seen later that shapes with non-parallel axial edges are possible for curved paths.

Les dimensions typiques d'un module sont pour le gabarit externe : longueur (le long de l'axe de la voie) 750mm, largeur (perpendiculairement à l'axe de la voie) à la base 2130 mm, largeur au sommet 2110 mm, hauteur 300 mm. Largeur du canal de l'auget à son sommet ouvert étroit 400 mm, à sa base large 480 mm et hauteur 200 mm. Distance de séparation des deux augets (= longueur du jambage) 720 mm. Largeur du jambage à la base 125 mm et au sommet 110 mm, le bord du jambage coté ouverture centrale étant incliné, la hauteur du jambage 200 mm. Il en résulte que l'ouverture mesure axialement (le long de l'axe de la voie) à la base du module 500 mm. La distance transversale séparant le sommet des deux augets est de 790 mm. Orifices 4 de prise du module de diamètre approximatif 40 mm. On comprend bien que ces dimensions sont approximatives et indicatives.The typical dimensions of a module are for the external gauge: length (along the axis of the track) 750mm, width (perpendicular to the track axis) at the base 2130 mm, width at the top 2110 mm, height 300 mm. Width of the bucket channel at its narrow open top 400 mm, at its wide base 480 mm and height 200 mm. Separation distance of the two buckets (= leg length) 720 mm. Width of the jamb at the base 125 mm and at the top 110 mm, the edge of the jamb side opening central being inclined, the height of the jamb 200 mm. As a result, the aperture measures axially (along the axis of the track) at the base of the 500 mm module. The transverse distance separating the top of the two buckets is 790 mm. 4 plug socket holes of approximate diameter 40 mm. It is understood that these dimensions are approximate and indicative.

Le moyen de liaison transversal 3 comporte ici deux jambages 31 séparés axialement par une ouverture 30 de communication. Les jambages 31 sont donc étendus entre les deux augets 2 afin que l'espace transversal comporte l'ouverture 30 pour communication entre les deux volumes définis au dessus et en dessous du module. Les deux jambages sont aux deux extrémités axiales (axe de la voie) du module. On peut remarquer Figure 2 et Figure 3 que le bord d'extrémité axiale 32 du jambage d'extrémité axiale du module est dans le même plan que les deux faces axiales 24 des deux augets 2 de même extrémité axiale du module afin que lorsque les modules sont accolés ensembles, il n'y ait pas de discontinuité sensible entre les bords d'extrémités axiales 32 de deux jambages adjacents et entre les deux faces axiales 24 de deux augets 2 adjacents. Il en résulte, au moins en section droite de voie, que le canal allongé formé de la mise bout à bout des canaux 20 d'un assemblage de modules accolés et alignés est sensiblement continu et ne présente pas de discontinuité dans l'alignement de ses faces internes latérales 21. Le béton fluide qui est coulé dans ces canaux alignés ne peut donc pas s'en échapper (sous la réserve de la présence d'orifices de prise 4).The transverse connection means 3 here comprises two legs 31 axially separated by an opening 30 of communication. Jambs 31 are therefore extended between the two buckets 2 so that the transverse space comprises the opening 30 for communication between the two volumes defined above and below the module. The two legs are at both axial ends (axis of the track) of the module. We can notice Figure 2 and Figure 3 that the axial end edge 32 of the axial end leg of the module is in the same plane as the two axial faces 24 of the two buckets 2 of the same axial end of the module so that when the modules are joined together, there is there is no substantial discontinuity between the axial end edges 32 of two adjacent legs and between the two axial faces 24 of two adjacent buckets 2. As a result, at least in the cross-section of the track, the elongate channel formed by the end-to-end splicing of the channels 20 of an assembly of contiguous and aligned modules is substantially continuous and has no discontinuity in the alignment of its internal lateral faces 21. The fluid concrete that is poured into these aligned channels can not escape (subject to the presence of the intake ports 4).

Le canal 20 de l'auget 2 est destiné à recevoir une longrine de béton armé 5 obtenue par coulage d'un béton fluide et comportant des tiges filetées et sur laquelle est posé et fixé le rail 8 correspondant par boulonnage sur les tiges filetées et utilisation de selles et patins 9 comme représenté Figure 6. Dans une variante représentée Figure 7, la longrine comporte un blochet 6 en béton armé fixé dans le canal par un béton de calage 7 et sur lequel est posé et fixé le rail 8 correspondant. Le rail 8 est fixé à la longrine ou au blochet par boulonnage sur des tiges filetées avec interposition de selles et utilisation de patins identifiés par la référence numérique commune 9 sur les Figures.The channel 20 of the bucket 2 is intended to receive a reinforced concrete sill 5 obtained by casting a fluid concrete and having threaded rods and on which is placed and fixed the corresponding rail 8 by bolting on the threaded rods and use of saddles and skates 9 as shown Figure 6 . In a variant represented Figure 7 , the sill comprises a rattle 6 reinforced concrete fixed in the channel by a concrete wedge 7 and on which is placed and fixed the corresponding rail 8. The rail 8 is fixed to the sill or the rattle by bolting on threaded rods with the interposition of saddles and use of pads identified by the common reference numeral 9 in the figures.

Figure 4, une voie ferrée double engazonnée a été réalisée. Elle repose sur un sol 10 préparé pour avoir une portance suffisante. Des réseaux 14, par exemple, électricité, signalisation, arrosage... ont également été réalisés. Des moyens de drainage 13 type drain agricole D80 ont également été réalisés. Les faces inférieures (bases) des deux augets 2 et des jambages 31 sont dans un même plan et le module repose donc uniformément sur le sol 10 formant la plate-forme. Le sol est soit un sol naturel, soit un sol rapporté et qui, dans les deux cas, est travaillé et sur lequel une couche de réglage peut être déposées pour un nivellement à +/- 1 cm. Dans cet exemple, un géotextile 15 posé sur la surface du sol est interposé entre le sol et les modules. Un remplissage adéquat formant une couche de remplissage 11 de hauteur correspondant sensiblement à la hauteur d'un module a été effectué. Sur cette couche de remplissage 11 est disposée la couche d'engazonnage 12 arrivant jusqu'au niveau supérieur des rails 8. Figure 4 a double grassed railway has been completed. It rests on a soil prepared to have sufficient lift. Networks 14, for example, electricity, signaling, watering ... have also been made. Drainage means 13 type agricultural drain D80 have also been made. The lower faces (bases) of the two buckets 2 and jambs 31 are in the same plane and the module therefore rests uniformly on the ground 10 forming the platform. The soil is either a natural soil or a reported soil and in both cases is worked and on which a layer of adjustment can be deposited for leveling to +/- 1 cm. In this example, a geotextile 15 placed on the ground surface is interposed between the ground and the modules. An adequate filling forming a filling layer 11 of height substantially corresponding to the height of a module has been performed. On this filling layer 11 is disposed the turf layer 12 arriving up to the upper level of the rails 8.

Les dimensions typiques en hauteur des différentes couches de la voie à partir du sol à la cote approximative - 490 mm jusqu'à l'air libre, coté engazonné, sont : couche de remplissage 300 mm, couche d'engazonnage 170 mm, hauteur libre de rail 20 mm au dessus de la couche d'engazonnage. On comprend bien que ces dimensions sont approximatives et indicatives, d'autant plus que la couche d'engazonnage comporte un élément vivant qui se développe.The typical height dimensions of the different layers of the track from the ground to the approximate dimension - 490 mm to the open air, grassed side, are: filling layer 300 mm, turf layer 170 mm, free height rail 20 mm above the turf layer. We understand that these dimensions are approximate and indicative, especially as the turf layer has a living element that develops.

Figure 5 on peut voir la disposition cote à cote, en alignement, des modules le long de la voie ferrée, en l'absence de la couche de remplissage et de l'engazonnage. De préférence, le ferraillage de la longrine s'effectue sur une longueur supérieure à la longueur (axiale) d'un module afin qu'un même fer passe à travers plusieurs augets de modules. Figure 5 we can see the layout side by side, in alignment, modules along the railway, in the absence of the filling layer and sodding. Preferably, the reinforcement of the sill is made over a length greater than the (axial) length of a module so that the same iron passes through several modules buckets.

Le principe général de pose des voies ferrées mettant en oeuvre les modules de l'invention est maintenant décrit. Sur la base (directement ou non, par exemple avec interposition d'un géotextile) d'une plate-forme terrassée et réglée avec une profondeur d'environ 50 cm par rapport au niveau fini du rail, des modules préfabriqués comportant des augets sont posés au contact les uns des autres, en alignement, pour permettre la constitution de deux alignements de canaux d'augets destinés à la réalisation de deux longrines parallèles par voie. Les rails équipés de blochets ou de selles de maintient sont ensuite positionnés sur les longrines réalisées à l'intérieur de ces augets et sont réglés en altimétrie et planimétrie de façon conventionnelle à l'aide de gabarits et de tiges de relevage. Un béton très plastique ou fluide est mis en oeuvre pour assurer le calage des rails à l'intérieur de chacun des augets, constituant ainsi deux longrines cohésives qui maintiendront les rails en place. Dans le cas d'utilisation de selles de maintien avec tiges d'ancrages, un ferraillage du béton de calage sera prévu sous forme de filants en acier ligaturés entre eux et de section adaptée. Dans le cas d'utilisation de blochets, ces derniers sont fixés dans les canaux des augets par la prise du béton qui y est coulé.The general principle of laying railways implementing the modules of the invention is now described. On the base (directly or not, for example with the interposition of a geotextile) a platform terraced and set with a depth of about 50 cm from the finished level of the rail, prefabricated modules with buckets are placed in contact with each other, in alignment, to allow the formation of two alignments of bucket channels for the realization of two longitudinal parallel runners. The rails equipped with rattles or saddles of maintenance are then positioned on the sills made inside these buckets and are adjusted in altimetry and planimetry in a conventional way using jigs and lifting rods. A very plastic or fluid concrete is used to ensure the setting of the rails inside each of the buckets, thus constituting two cohesive stringers that will keep the rails in place. In the case of using saddles holding with anchor rods, reinforcement concrete reinforcement will be provided in the form of steel rods ligated together and adapted section. In the case of use of rattles, the latter are fixed in the channels of the buckets by the setting of the concrete which is poured therein.

Une fois les voies montées de la sorte, un remplissage en grave D2 ou calcaire de granulométrie adaptée par rapport au substrat végétal devant être mis en place, est réalisé sur les rives de la plate-forme, entre les rails et entre les voies, formant la couche de remplissage.Once the tracks mounted in this way, a D2 gravel or grading of appropriate particle size with respect to the plant substrate to be implemented, is performed on the banks of the platform, between the rails and between the tracks, forming the filling layer.

A noter que dans l'intervalle, il aura été mis en place tous les réseaux nécessaires (secs et humides) au dispositif d'arrosage automatique, dans l'épaisseur de la structure de la voie.It should be noted that in the meantime, all the necessary networks (dry and wet) have been set up for the automatic irrigation device, in the thickness of the track structure.

Typiquement, dans le cas de deux voies parallèles, l'écartement entre les deux voies de circulation (à l'entraxe) est de 3,4 m et peut descendre localement à 3,0 m. L'écartement entre les deux rails est de 1,435 m. L'espacement longitudinal des blochets est de 0,75 m.Typically, in the case of two parallel tracks, the spacing between the two traffic lanes (at the center distance) is 3.4 m and can fall locally to 3.0 m. The distance between the two rails is 1.435 m. The longitudinal spacing of the blocks is 0.75 m.

En pratique, le dimensionnement des modules préfabriqués et du béton de longrine est déterminé par calcul sur la base de données relatives au matériel roulant qui doit emprunter la voie (charges à l'essieu, entraxe de bogies, contact rail/roue, etc.) et aux conditions de circulation des tramways (vitesse, profil, courbes, freinages, etc.).In practice, the dimensioning of prefabricated modules and sill concrete is determined by calculation based on rolling stock data which must follow the track (axle loads, bogie spacings, rail / wheel contact, etc.). and tramway traffic conditions (speed, profile, curves, braking, etc.).

A titre d'exemple, on peut considérer les éléments qui suivent et qui ont servis à effectuer des calculs de résistance pour des modules de structure donnée et une mise en oeuvre avec blochets. La chaussée du tramway repose sur un sol de module fixé à E = 35 MPa ou E = 50 MPa. La plate-forme est constituée de modules à deux augets et deux jambages en béton préfabriqué à l'intérieur desquels sont posés les blochets supportant les rails. Les blochets disposés dans les canaux des augets sont noyés dans un béton de calage. Un ferraillage des augets, jambages et des blochets est réalisé. A titre d'exemple, il est mis en oeuvre des armatures pour le béton armé qui sont des barres à haute adhérence de nuance FeE500 et avec un enrobage minimum de 3 cm.For example, we can consider the following elements that were used to perform resistance calculations for modules of given structure and implementation with blocks. The roadway of the tramway is based on a module ground fixed at E = 35 MPa or E = 50 MPa. The platform consists of modules with two buckets and two jambs precast concrete inside which are placed the rattles supporting the rails. Blocks placed in the channels of the buckets are embedded in a concrete blocking. A reinforcement of the buckets, jambs and blochets is realized. For example, it is implemented reinforcement for reinforced concrete which are high-adhesion bars of FeE500 grade and with a minimum coating of 3 cm.

Les blochets et les modules sont constitués de béton de classe C50 (fc28 = 50 MPa). Le béton de calage est un béton de classe C30 (fc28 = 30 MPa).Blocks and modules consist of Class C50 concrete ( fc28 = 50 MPa). The setting concrete is a class C30 concrete (f c28 = 30 MPa).

Il a été calculé dans diverses conditions et notamment de charge de la voie, que les tassements et contraintes restaient inférieurs aux limites généralement admises pour les matériaux considérés. De même, la reprise des efforts horizontaux et dus à la dilatation est satisfaisante.It has been calculated under various conditions and in particular the load of the track that the settlements and stresses remained below the generally accepted limits for the materials considered. Similarly, the recovery of horizontal forces and due to expansion is satisfactory.

Plus en détail, la réalisation de la voie ferrée avec les modules de l'invention nécessite que la plate-forme sur laquelle repose la voie soit terrassée, réglée et stabilisée au niveau moins 50 cm par rapport au plan de roulement du rail avec une tolérance de -1/+2 cm, ou mieux +/- 1 cm. Cette plate-forme constitue le sol qui est soit d'origine, soit rapporté selon les caractéristiques initiales locales du terrain. La portance de la plate-forme doit permettre d'obtenir un EV2 > 35 Mpa. De préférence, cette caractéristique doit être vérifiée par un essai de plaque à même la plate-forme ou fond de forme.In more detail, the realization of the railway with the modules of the invention requires that the platform on which the track rests be earthed, adjusted and stabilized at least 50 cm with respect to the running surface of the rail with a tolerance -1 / + 2 cm, or better +/- 1 cm. This platform is the soil that is either original or reported according to the initial local characteristics of the land. The lift of the platform must make it possible to obtain an EV2> 35 MPa. Preferably, this characteristic must be verified by a plate test on the platform or bottom of form.

La plate-forme doit être propre et exempte d'aspérité. Le cas échéant et afin de s'affranchir des éventuelles intempéries qui pourraient dégrader la portance du fond de forme, un traitement de surface par gravillonnage et application d'une couche d'émulsion pourra être préconisé. De même, en cas d'inégalité du fond de forme, une fine couche de sable ou de granulats criblés de granulosités réduite (0/8 mm) pourra être disposée et proprement régalée avant la pose des modules.The platform must be clean and free of roughness. If necessary and in order to overcome the possible bad weather that could degrade the lift of the bottom of form, a surface treatment by gravelling and application of an emulsion layer may be recommended. Similarly, in case of unevenness of the bottom of form, a thin layer of sand or aggregates screened with reduced granulosities (0/8 mm) may be arranged and properly regaled before laying the modules.

Dans le cas où la voie est totalement construite in situ, les rails sont livrés sur le chantier par camions à remorques extensibles, à raison de 22 rails de 18 ml par camion. Ils sont déchargés à l'aide d'une pelle mécanique équipée d'une pince à rail. En cas de besoin, les rails sont élingués pour limiter leur amplitude de mouvement. Les rails sont distribuées le long de la plate-forme, de chaque coté de la future voie. Dans une autre modalité de réalisation, les rails sont amenés sur le chantier après la mise en place des modules.In the case where the track is completely built in situ, the rails are delivered to the site by extensible trailer trucks, with 22 rails of 18 ml per truck. They are unloaded using a digger equipped with a rail clamp. If necessary, the rails are slung to limit their range of motion. The rails are distributed along the platform, on each side of the future track. In another embodiment, the rails are brought to the site after the introduction of the modules.

Les modules à augets et jambages sont ensuite livrés par camions semi-remorques directement depuis leur site de fabrication ou bien depuis un lieu de stockage proche du chantier. Conditionnés sur bois de calage, les augets sont déchargés à l'aide d'une pelle mécanique équipée de fourches ou à l'aide d'un chariot élévateur. Ils sont disposés directement bord à bord, alignés, pour continuité des canaux des augets, sur la plate-forme, le long de repères d'alignement de voie préalablement mis en place par les géomètres.Bucket and leg modules are then delivered by semi-trailer trucks directly from their manufacturing site or from a storage near the site. Packed on timbers, the buckets are unloaded using a digger equipped with forks or using a forklift. They are arranged directly edge to edge, aligned for continuity bucket channels, on the platform, along track alignment marks previously set up by the surveyors.

Une fois les modules mis en place, les rails sont positionnés sur des supports en bois en appui sur les faces supérieures des augets. Des selles isolantes équipées d'un système d'attache (Nabla®) sont ensuite montées sur les rails. Une fois l'armement de la voie réalisé, un système de réglage altimétrique et planimétrique est ensuite mis en place sur les rails (gabarits de réglage) afin de permettre le positionnement en X, Y, Z des voies. Les rails sont alors soudés par aluminothermie. Le garnissage des rails est réalisé de façon conventionnelle avant que les rails ne soient calés dans le béton de longrines, pour pouvoir accéder au patin du rail et assurer le meilleur isolement possible.Once the modules are in place, the rails are positioned on wooden supports resting on the upper faces of the buckets. Insulating saddles equipped with an attachment system (Nabla®) are then mounted on the rails. Once the arming of the track has been achieved, an altimetric and planimetric adjustment system is then put in place on the rails (adjustment jigs) in order to allow positioning in X, Y, Z of the tracks. The rails are then welded by aluminothermie. The lining of the rails is done in a conventional way before the rails are wedged in the concrete of sills, in order to be able to access the runner of the rail and to ensure the best possible insulation.

A noter que dans le cas de zones difficiles d'accès ou nécessitant un impact chantier limité pour les riverains, les commerçants et les usagers, les rails peuvent être pré montés en atelier avec les selles déjà assemblées et les pièces de garnissage des rails mis en place et livrés sur le chantier directement par des moyens conventionnels (camions semi-remorque et pelles mécaniques). Le montage sur place se trouve alors particulièrement accéléré et le délai global d'intervention peut être considérablement raccourci.It should be noted that in the case of areas that are difficult to reach or that require limited site impact for local residents, shopkeepers and users, the rails can be pre-assembled in the workshop with the already assembled saddles and the rail packing pieces installed. placed and delivered on site directly by conventional means (semi-trailer trucks and excavators). On-site assembly is then particularly accelerated and the overall response time can be significantly shortened.

Dans une variante encore plus rapide à mettre en oeuvre, ce sont des sections préfabriquées de voie ferrée à deux rails, de longueur déterminée qui sont livrées et posées sur la plate-forme. Chacune de ces sections comporte un ensemble de modules alignés et accolés ensembles, deux longrines en béton armées réalisées par coulage de béton dans chacun des deux canaux des augets, lesdites longrines comportant en outre des tiges filetées, des selles et patins étant disposés sur les longrines, les rails étant disposés sur les selles et étant boulonnés avec des patins aux tiges filetées pour fixation. Les divers réseaux éventuels peuvent être installés dans les nombreuses zones réservées.In an even faster variant to implement, it is prefabricated railway sections with two rails, of fixed length that are delivered and placed on the platform. Each of these sections comprises a set of modules aligned and joined together, two reinforced concrete sills made by pouring concrete in each of the two channels of the buckets, said sills further comprising threaded rods, saddles and pads being arranged on the sills , the rails being disposed on the saddles and being bolted with pads to the threaded rods for fixing. The various possible networks can be installed in the many reserved areas.

Pour le calage de la voie réalisée in situ, le réglage fin est réalisé par les géomètres et une fois les voies correctement positionnées, elles sont calées par coulage d'un béton de granulométrie adaptée (0-16), très plastique ou auto plaçant si la géométrie des voies le permet. Une fois que le béton a fait sa prise, les équipements de réglage sont déposés et évacués, les travaux de nettoyage et de finitions peuvent être alors réalisés.For the calibration of the track realized in situ, the fine adjustment is carried out by the surveyors and once the tracks correctly positioned, they are wedged by pouring a concrete of suitable size (0-16), very plastic or self-placing if the geometry of the tracks allows it. Once the concrete has set, the adjustment equipment is removed and evacuated, and the cleaning and finishing work can be done.

Un remplissage de tous les vides de la plate-forme (entre rails, rives et entre voie) peut ensuite être réalisé à l'aide d'une grave calcaire, de tout venant de faible granulométrie (0/10 par exemple) ou de terre végétale alourdie par un mélange de sable et de cailloux (4-16 mm). Ce remblai destiné à former la couche de remplissage 11 subira ensuite un compactage et sera régalé au niveau moins 20 cm approximativement pour réserver le reste de la structure à la pose du substrat à engazonner et au semis du gazon formant la couche engazonnée 12.A filling of all the voids of the platform (between rails, banks and between lane) can then be realized using a serious limestone, any coming of small particle size (0/10 for example) or earth plant weighted by a mixture of sand and pebbles (4-16 mm). This backfill intended to form the filling layer 11 will then undergo compacting and will be regaled at least 20 cm approximately to reserve the rest of the structure for the laying of the substrate to be sodded and the sowing of the grass forming the turfed layer 12.

Les modules sont fabriqués par des méthodes classiques de moulage de béton dans des moules contenant un ferraillage. Cependant, pour la réalisation des canaux des augets en forme de queue d'aronde qui comportent un rentrant, lors du moulage on installe dans le moule une contreforme en acier ou une pièce perdue en plastique par exemple, qui permet de réaliser le rentrant et qui sera enlevée une fois le béton pris. Le ferraillage est étendu aussi bien dans les augets que dans les jambages. Par ailleurs, lors de la réalisation ultérieure des longrines, un ferraillage est également mis en place dans les canaux des augets avant que du béton fluide y soit coulé.The modules are manufactured by conventional methods of molding concrete in molds containing a reinforcement. However, for the realization of dovetail-shaped buckets channels which comprise a reentrant, during molding is installed in the mold a steel counterfoil or a lost piece of plastic for example, which allows the re-entrant and which will be removed once the concrete is taken. The reinforcement is extended both in the buckets and in the jambs. Furthermore, during the subsequent realization of the longitudinal members, a reinforcement is also set up in the channels of the buckets before fluid concrete is poured therein.

Les modules tels que décrits jusqu'à présent et qui ont un gabarit externe globalement parallélépipédique sont spécifiquement adaptés à des sections de voie linéaire (=droite) puisqu'il faut éviter des discontinuités entre les parois latérales des canaux alignés des augets et à travers lesquelles le béton fluide qui est coulé pour réaliser la longrine pourrait s'échapper. En effet, ce gabarit assure une continuité des parois des canaux alignés pour une voie linéaire. Dans le cas où une courbe est présente, plusieurs solutions sont possibles. Si la courbe a un grand rayon, le décalage angulaire entre les modules de gabarit parallélépipédique sera faible et les discontinuités entre les parois de canaux successif faible et on peut envisager de combler ces discontinuités avant le coulage du béton fluide de longrine par des bouchons en toute matière adéquate. A titre d'autre exemple, on peut isoler ces discontinuités par une bande de largeur réduite disposée dans les extrémités adjacentes de canaux de deux augets de deux modules adjacents et en pont sur la discontinuité, la bande peut être par exemple souple en caoutchouc vulcanisé ou un clip en matière plastique épousant la forme en queue d'aronde des faces du canal. Dans ce dernier cas, le béton coulé de la longrine ne sera plus au contact des parois et fond du canal vers les extrémités dudit canal d'un auget pour un module donné. Dans une variante une telle bande souple est disposée tout le long des canaux aussi bien en section linéaire que courbe de voie et ainsi, le béton de la longrine est séparé des parois et fonds des canaux des augets par la bande qui peut être résiliente, ce qui peut donner un effet d'amortissement/souplesse/isolation supplémentaire dans la voie.The modules as described heretofore and which have a generally parallelepipedal external template are specifically adapted to linear track sections (= right) since it is necessary to avoid discontinuities between the side walls of the aligned channels of the buckets and through which the fluid concrete that is poured to make the sill could escape. Indeed, this template ensures continuity of the walls of the aligned channels for a linear path. In the case where a curve is present, several solutions are possible. If the curve has a large radius, the angular offset between the parallelepipedal template modules will be small and the discontinuities between the successive low channel walls and it can be envisaged to fill these discontinuities before the pouring of the stiletto fluid concrete by plugs in all adequate material. As another example, these discontinuities can be isolated by a band of reduced width disposed in the adjacent ends of channels of two buckets of two adjacent modules and bridged over the discontinuity, the band may for example be flexible vulcanized rubber or a plastic clip conforming to the dovetail shape of the faces of the channel. In the latter case, the cast concrete of the sill will not be in contact with the walls and bottom of the channel to the ends of said channel of a bucket for a given module. In one variant, such a flexible strip is arranged all along the channels in both linear and track sections, and thus the concrete of the sill is separated from the walls and bottoms of the channels of the buckets by the band which can be resilient, which can give an additional damping / flexibility / insulation effect in the track.

Une autre solution pour les portions en courbe de la voie est de mettre en oeuvre des modules qui ont une forme non plus à deux faces d'extrémités axiales parallèles entre elles mais qui soient convergentes, vu de dessus le module ayant alors une forme externe en triangle à sommet tronqué. On comprend cependant que cette solution pour que la continuité entre les canaux des augets soit parfaite nécessite la réalisation de modules dont les angles de convergence des faces d'extrémités axiales soient parfaitement adaptés au rayon de courbure de la voie. Si cela n'est pas le cas, il y aura discontinuité et on se retrouve dans le cas décrit plus haut et les solutions présentées peuvent alors être mises en oeuvre pour combler/isoler les discontinuités et éviter la fuite du béton fluide lors de son coulage pour réalisation de la longrine.Another solution for the curved portions of the track is to implement modules which have a shape no longer with two faces of axial ends parallel to each other but which are convergent, seen from above the module then having an external shape. triangle with truncated vertex. However, we understand that this solution for the continuity between the buckets channels is perfect requires the realization of modules whose angles of convergence of the axial end faces are perfectly adapted to the radius of curvature of the track. If this is not the case, there will be discontinuity and we find ourselves in the case described above and the solutions presented can then be implemented to fill / isolate the discontinuities and prevent leakage of the fluid concrete during its casting for realization of the sill.

On comprend bien que l'invention peut être déclinée selon de nombreuses autres possibilités sans pour autant sortir du cadre défini par la description et les revendications.It is well understood that the invention can be declined according to many other possibilities without departing from the scope defined by the description and the claims.
