Abstract

The construction process for a tramway track (16) comprises several stages. The sides (3,4) and the underside (5) of a rail (1) are coated with a resilient material (2) before placing on supports (10) on top of a foundation baseplate (13). The supports are adjusted into a position where the surface of the rails is at the same level as the track surface. Concrete (31) is then poured around and under the coated rail to form the road surface (32).

Description

La présente invention a pour objet un procédé de construction d'une voie de chemin de fer, de préférence une voie de chemin de fer en site urbain, notamment pour la réalisation d'un tramway. Elle peut être néanmoins utile dans d'autres domaines, chemins de fer de rase campagne, où les problèmes rencontrés sont du même type que ceux résolus par l'invention.The subject of the present invention is a method of construction a railway track, preferably an elevated railway track urban, especially for the construction of a tram. She may be nevertheless useful in other fields, rural railways, where the problems encountered are of the same type as those solved by the invention.

Une voie ferrée en site urbain se compose en général de quatre sous-ensembles : une plateforme qui se situe sous une couche de fondation, une couche de roulement du tramway qui supporte le rail et ses ancrages et une couche de revêtement qui constitue la partie apparante de l'ouvrage terminé. Cette dernière peut être réalisée en divers matériaux : de la terre engazonnée, une ou plusieurs couches de béton bitumineux et des enrobés bitumineux, des pavés, des dalles de béton, des pierres posées sur sable, du gravier, ou du béton. La réalisation d'une voie de chemin de fer en site urbain pour tramway implique un certain nombre de contraintes qu'il faut satisfaire d'une manière impérative. S'agissant de tramway, à traction électrique, le retour du courant doit être assuré par les rails. En conséquence, la continuité électrique doit être assurée sans défaut. En effet, de nombreux réseaux d'équipements publics sont enterrés dans les voiries des villes. Or, les fuites de courant par les rails provoquent des phénomènes d'électrolyse des parties métalliques des différents réseaux enterrés. Le problème est particulièrement grave en ce qui concerne le transport du gaz, où l'altération des conduites peut conduire à des fuites de gaz qui elles-mêmes donnent lieu à des explosions quand le gaz, qui s'échappe, s'accumule dans une fosse, une cave par exemple. Pour éviter ce problème, il est nécessaire d'isoler le plus possible le rail, électriquement, du milieu où il repose.A railway track in an urban site generally consists of four sub-assemblies: a platform located under a foundation layer, a tramway wearing course which supports the rail and its anchors and a covering layer which constitutes the visible part of the structure completed. The latter can be made of various materials: earth turfed, one or more layers of bituminous concrete and mixes bituminous, paving stones, concrete slabs, stones laid on sand, gravel, or concrete. The construction of a railway track in an urban site for tram involves a certain number of constraints which must be satisfied imperatively. As it is a tram, with electric traction, the current return must be ensured by the rails. As a result, continuity electric must be ensured without fault. Indeed, many networks public facilities are buried in city streets. Leaks of current through the rails cause electrolysis phenomena of metal parts of the different buried networks. The problem is particularly serious with regard to the transport of gas, where the alteration pipes can lead to gas leaks which themselves give explosions when the escaping gas collects in a pit, a cellar for example. To avoid this problem, it is necessary isolate the rail as much as possible, electrically, from the environment in which it rests.

En outre, notamment lorsque le rail est réalisé dans une voirie urbaine, il ne faut pas qu'il soit le siège d'infiltrations d'eau. En effet, l'eau en s'infiltrant dans le corps de chaussée environnant provoque des phénomènes de remontées plastiques qui amoindrissent la tenue de la fondation. La chaussée se dégrade du fait qu'elle n'est plus étanche. In addition, especially when the rail is made in a roadway urban, it must not be the seat of water infiltration. Indeed, the water in seeping into the surrounding pavement body causes plastic lift phenomena which reduce the holding of the foundation. The roadway deteriorates because it is no longer waterproof.

Enfin, on porte de plus en plus attention, aujourd'hui, aux effets du bruit provoqué par les chocs et vibrations des roues des trains et des véhicules qui croisent sur les rails et qui se propage jusqu'aux habitations avoisinantes.Finally, we are paying more and more attention today to the effects of noise caused by shock and vibration from train wheels and vehicles crossing the rails and spreading to dwellings neighboring.

Il est déjà connu, pour remédier à ce type de problèmes, de poser les rails sur des socles, en général des traverses, et de munir ensuite les rails d'une protection d'enrobage élastique. La difficulté rencontrée vient de ce que le rail, en place, est maintenu environ tous les 70 cm, voire tous les 50 cm sur les traverses, et que l'incorporation des protections d'enrobage est fastidieuse d'une part, et n'est pas très efficace d'autre part.It is already known, to remedy this type of problem, to pose the rails on bases, in general of the sleepers, and then to provide the elastic coating protection rails. The difficulty encountered comes from that the rail, in place, is held approximately every 70 cm, or even every 50 cm on the sleepers, and that the incorporation of coating protections is tedious on the one hand, and not very effective on the other.

En effet, à l'endroit où le rail repose sur les traverses, il n'est pas possible d'assurer la continuité de l'enrobage. Il en résulte des troubles partiels, mais non négligeables. En outre, dans le cas de réalisation de voie ferrée urbaine, il est nécessaire que le dessus du rail affleure au niveau de la chaussée. Du fait du mode opératoire ainsi imaginé, poses de rails, fixations des rails, enrobages des tronçons des rails, et mises à niveau de l'espace autour des rails, la charge de main-d'oeuvre en quatre étapes devient lourde à supporter.Indeed, at the place where the rail rests on the sleepers, it is not possible to ensure the continuity of the coating. This results in troubles partial, but not negligible. In addition, in the case of track construction urban rail, it is necessary that the top of the rail is flush with the pavement. Due to the operating method thus imagined, rail laying, fixings rails, coatings of rail sections, and space upgrades around the rails, the workload in four stages becomes heavy to support.

Ce problème est particulièrement ressenti dans les pays fortement développés, qui sont par ailleurs amateurs de tramway, où la main-d'oeuvre n'est jamais bon marché. En outre, pour tenter de résoudre le problème de la discontinuité des tronçons d'enrobage, il a été réalisé des accessoires, finalement très complexes à mettre en place. Notamment, la fixation du rail et/ou la fixation des tronçons d'enrobage, nécessite la mise en place de supports provisoires qu'il convient d'enlever avant la finition du revêtement. Ces accessoires gênent par ailleurs la mise en place automatique du revêtement par une machine du type à coffrage glissant dans le cas de la réalisation d'un béton de ciment.This problem is particularly felt in countries with strong developed, who are also tram enthusiasts, where the workforce is never cheap. Furthermore, in an attempt to resolve the problem of discontinuity of the coating sections, accessories have been produced, ultimately very complex to set up. In particular, the fixing of the rail and / or fixing the coating sections, requires the installation of temporary supports which must be removed before finishing the coating. These accessories also hamper the automatic positioning of the coating by a machine of the sliding formwork type in the case of concrete cement.

La présente invention a pour objet de remédier à ces inconvénients par un procédé complètement différent, remettant en cause toutes les techniques utilisées jusqu'ici. Selon l'invention, on renonce à fixer de manière rigide, de place en place, classiquement, le rail sur des traverses ou des supports. Au contraire, on enrobe le rail, avant sa mise en place sur toute sa longueur, sur les côtés et par en dessous, de manière à ce qu'il soit enrobé complètement dans un matériau élastique. The object of the present invention is to remedy these disadvantages by a completely different process, calling into question all the techniques used so far. According to the invention, it gives up fixing rigidly, from place to place, conventionally, the rail on sleepers or supports. On the contrary, the rail is coated, before it is placed on its entire length, on the sides and below, so that it is completely wrapped in elastic material.

Bien entendu, l'enrobage ne recouvre pas le rail dont la partie supérieure servira toujours de surface de roulement pour le train. Du fait de la forme en I du rail, l'enrobage constitue alors une structure autobloquante de maintien du rail sur toute sa longueur. Ce maintien, tout en étant élastique, est effectué en continu. Il n'a pas besoin par conséquent d'être aussi puissant qu'une fixation intermittente. Il en résulte que le rail est bien maintenu dans son enrobage.Of course, the coating does not cover the rail, the part of which will always serve as a running surface for the train. Because of the I-shape of the rail, the coating then constitutes a self-locking structure rail maintenance over its entire length. This maintenance, while being elastic, is carried out continuously. It therefore does not need to be as powerful as intermittent fixation. As a result, the rail is well maintained in its coating.

Par ailleurs, l'enrobage est lui-même ensuite maintenu en place dans un béton coulé sur toute sa longueur de manière à assurer son maintien dans le corps de la chaussée dans le cas d'un revêtement en béton de ciment.Furthermore, the coating is itself then held in place in a concrete poured over its entire length so as to ensure its maintenance in the body of the roadway in the case of a concrete coating cement.

On montrera que le procédé de l'invention permet de réaliser en trois étapes seulement au lieu de quatre précédemment, la mise en place du rail.It will be shown that the method of the invention makes it possible to carry out only three steps instead of four previously, the establishment of the rail.

L'invention a donc pour objet un procédé de construction d'une voie de chemin de fer urbaine, notamment pour tramway, caractérisé en ce qu'il comporte les étapes suivantes :

  • on enrobe les cotés et le dessous d'un rail avec un matériau élastique selon un profil d'enrobage affleurant à la surface supérieure du rail,
  • on réalise une semelle de fondation dans une voie de circulation urbaine,
  • on supporte et on règle, après réalisation de l'enrobage, avec des supports provisoires le rail enrobé au dessus de cette semelle, dans une position où sa surface affleurante est destinée à être définitive et sensiblement au même niveau que la surface de la voie de circulation urbaine,
  • on coule en place, autour et en dessous du rail enrobé, une masse de béton s'élevant vers la surface de la voie urbaine pour maintenir le rail et servir à la réalisation de la surface de chaussée.
The subject of the invention is therefore a method of constructing an urban railway track, in particular for a tram, characterized in that it comprises the following steps:
  • the sides and the underside of a rail are coated with an elastic material according to a coating profile flush with the upper surface of the rail,
  • we make a foundation sole in an urban traffic lane,
  • support and adjust, after completion of the coating, with temporary supports the coated rail above this sole, in a position where its flush surface is intended to be final and substantially at the same level as the surface of the track city traffic,
  • we pour in place, around and below the coated rail, a mass of concrete rising towards the surface of the urban road to maintain the rail and serve for the realization of the road surface.

L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles-ci ne sont données qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent :

  • Figure 1 : une représentation schématique de la mise en place d'un rail selon le procédé de l'invention,
  • Figures 2a et 2b: les détails d'une phase d'enrobage du rail selon une étape essentielle du procédé de l'invention,
  • Figure 3: une variante de réalisation de l'enrobage permettant une amovibilité du rail dans son enrobage.
The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are given for information only and in no way limit the invention. The figures show:
  • FIG. 1: a schematic representation of the installation of a rail according to the method of the invention,
  • FIGS. 2a and 2b: the details of a coating phase of the rail according to an essential step of the method of the invention,
  • Figure 3: an alternative embodiment of the coating allowing the rail to be removable in its coating.

La figure 1 montre, schématiquement, les différentes étapes du procédé de l'invention. Elle montre un rail 1 enrobé dans un enrobage 2. L'enrobage 2 peut être du caoutchouc, du PVC ou tout autre matériau élastique, notamment un polymère. L'enrobage 2 possédera naturellement une certaine rigidité. L'enrobage 2 enrobe le rail 1 essentiellement sur les côtés 3 et 4 du rail, et sous le dessous 5 du rail. Par exemple, la couche 5 située sous le rail aura une épaisseur de 2 cm environ. L'enrobage forme au sommet du rail une surface qui prolonge le rail de part et d'autre à un même niveau ou à un niveau voisin, le rail pouvant être en légère saillie. Ainsi enrobé, le rail 1 forme un caisson dont la section est de l'ordre de 20 cm par 20 cm. Dans l'exemple représenté, le rail 1 est un rail à omière 6. Néanmoins, il est envisageable de prévoir des rails simples. Dans ce cas, l'enrobage 2 comportera une cavité pour permettre l'insertion du boudin de la roue du train.Figure 1 shows, schematically, the different stages of method of the invention. It shows a rail 1 embedded in a coating 2. Coating 2 can be rubber, PVC or any other material elastic, in particular a polymer. Coating 2 will naturally have a certain rigidity. Coating 2 coats the rail 1 essentially on the sides 3 and 4 of the rail, and under the underside 5 of the rail. For example, layer 5 located under the rail will be approximately 2 cm thick. The coating forms at top of the rail a surface which extends the rail on both sides to the same level or at a neighboring level, the rail may protrude slightly. So coated, the rail 1 forms a box whose section is of the order of 20 cm per 20 cm. In the example shown, the rail 1 is a shaded rail 6. However, it is conceivable to provide simple rails. In that case, coating 2 will include a cavity to allow insertion of the flange of the train wheel.

Le rail enrobé est porté de préférence, au moins localement, dans des berceaux 7. Les berceaux 7 sont des parties métalliques, en forme globalement de U et qui épousent la forme de la section du rail enrobé dans sa partie inférieure. Les berceaux 7 ne sont pas nécessaires si le matériau élastique d'enrobage est suffisamment rigide. Ils peuvent être particulièrement utiles si ce matériau est du caoutchouc.The coated rail is preferably worn, at least locally, in cradles 7. The cradles 7 are metal parts, in the form overall of U and which follow the shape of the section of the rail coated in its lower part. Cradles 7 are not necessary if the material elastic coating is sufficiently rigid. They can be particularly useful if this material is rubber.

Les berceaux 7 sont munis, sur leurs flancs verticaux, de part et d'autre du rail enrobé, de corbeaux 8 comportant chacun un alésage fileté 9 vertical. Dans les alésages 9, sont vissées des tiges filetées 10 dont la tête peut être manoeuvrée selon une rotation 11 pour s'enfoncer plus ou moins le long du filetage 9. Les tiges filetées 10 possèdent une base 12 qui repose sur une semelle 13 de fondation réalisée préalablement.The cradles 7 are provided, on their vertical sides, on the side and on the other side of the coated rail, with crows 8 each comprising a threaded bore 9 vertical. In the bores 9, threaded rods 10 are screwed, the head of which can be operated according to a rotation 11 to sink more or less the along the thread 9. The threaded rods 10 have a base 12 which rests on a foundation 13 made previously.

Par exemple, la semelle 13 est réalisée sur le fond 14 d'une tranchée 15. La tranchée 15 est réalisée dans une chaussée existante 16. La chaussée 16 peut aussi être une chaussée à créer. La base 12 de la tige 10, repose sur la semelle de fondation 13, de préférence par l'intermédiaire d'une plaque de réaction 17 qui évite sa pénétration dans la fondation 13. En effet, celle-ci peut être munie de réseaux divers: télésignalisation 18, alimentation électrique 19, ou autres. La plaque de réaction 17 est particulièrement nécessaire si la constitution de la semelle de fondation est faite avec un béton maigre peu résistant. Autrement, on peut s'en passer.For example, the sole 13 is made on the bottom 14 of a trench 15. Trench 15 is made in an existing roadway 16. The pavement 16 can also be a pavement to be created. The base 12 of the rod 10, rests on the foundation plate 13, preferably via a reaction plate 17 which prevents its penetration into the foundation 13. In Indeed, it can be provided with various networks: remote signaling 18, power supply 19, or others. The reaction plate 17 is particularly necessary if the constitution of the foundation sole is made with lean concrete with little resistance. Otherwise, we can do without it.

En agissant sur les tiges filetées 10, on peut régler le rail en position verticale, de manière à ce que sa surface supérieure soit affleurante à l'altitude de la chaussée finie 16. De préférence, les longueurs des tiges filetées 10 seront inférieures à la hauteur qui sépare la plaque 17, ou la semelle 13, de cette altitude de chaussée finie. De cette façon, à l'issue, il ne sera pas nécessaire d'enlever les tiges filetées 10 qui resteront perdues dans la masse de béton d'enrobage.By acting on the threaded rods 10, the rail can be adjusted in vertical position, so that its upper surface is flush at the altitude of the finished roadway 16. Preferably, the lengths of the rods threaded 10 will be less than the height which separates the plate 17, or the sole 13, of this finished pavement altitude. In this way, at the end, it does not will not be necessary to remove the threaded rods 10 which will remain lost in the mass of coating concrete.

Pour réaliser une voie, bien entendu, on met en place deux rails et un deuxième rail 20 peut être mis en place de la même façon que le rail 1. Le rail 20 sera par ailleurs réglé en écartement par rapport au rail 1 par une entretoise 21 comportant une double bride 22, à vis sans fin.To make a track, of course, two rails are put in place and a second rail 20 can be installed in the same way as rail 1. The rail 20 will also be adjusted in spacing relative to rail 1 by a spacer 21 comprising a double flange 22, worm.

L'entretoise 21 comporte ainsi deux tiges filetées 23 et 24 qui prennent appui, en poussée et en traction, dans deux corbeaux respectivement 25 et 26. Par une rotation 27 de la bride 22, on règle l'écartement des rails 1 et 20. Si le matériau d'enrobage est relativement mou, les corbeaux 25 et 26 seront portés par des berceaux 7 et 28. Par contre, si le matériau 2 est plus résistant, les corbeaux peuvent y être appliqués directement. La position en altitude de l'entretoise 21 sera notablement inférieure à la surface de la chaussée finie 16. Au besoin, les corbeaux 25 et 26 seront fixés sous les berceaux.The spacer 21 thus comprises two threaded rods 23 and 24 which take support, in push and pull, in two crows 25 and 26 respectively. By rotation 27 of the flange 22, one adjusts the spacing of the rails 1 and 20. If the coating material is relatively soft, crows 25 and 26 will be carried by cradles 7 and 28. By however, if the material 2 is more resistant, the crows can be there applied directly. The altitude position of the spacer 21 will be significantly less than the surface of the finished pavement 16. If necessary, crows 25 and 26 will be fixed under the cradles.

Une fois que les rails enrobés de matériaux élastiques sont ainsi supportés et réglés au-dessus de la semelle de fondation 13, on coule en place une masse de béton pour maintenir le rail. Le béton peut être un béton de ciment, un béton bitumineux ou plus généralement tout matériau permettant une mise en place par coulage et effectuant ensuite une prise durcissante hydraulique, thermique (asphalte) ou même chimique (émulsion). Ce coulage en place est par exemple obtenu, par un dispositif 29 de dispense situé à l'avant par rapport à un sens d'avancement 30 d'un ensemble 34 de mise en place. La dispense 29 peut comporter plusieurs orifices d'épandage situés notamment de part et d'autre et entre les deux rails 1 et 20. Du béton fluide 31 coule ainsi au-dessus de la semelle 13, sous la partie inférieure 5 de l'enrobage 2, et de part et d'autre des flancs verticaux des rails enrobés. A l'arrière de la dispense 29, se trouve une règle de lissage 32 ainsi qu'une aiguille vibrante 33 qui plonge dans la masse, relativement liquide, du béton qui vient d'être mis en place.Once the rails coated with elastic materials are thus supported and adjusted above the foundation sole 13, we sink in places a mass of concrete to hold the rail. Concrete can be concrete cement, bituminous concrete or more generally any material allowing placement by pouring and then setting hardening hydraulic, thermal (asphalt) or even chemical (emulsion). This pouring in place is for example obtained by a device 29 for exemption located at the front with respect to a direction of advance 30 of a set 34 of implementation. Exemption 29 may include more than one spreading orifices located in particular on either side and between the two rails 1 and 20. Fluid concrete 31 thus flows over the sole 13, under the lower part 5 of the coating 2, and on either side of the sides vertical coated rails. At the back of dispensation 29 is a rule smoothing 32 as well as a vibrating needle 33 which plunges into the mass, relatively liquid, concrete that has just been put in place.

La dispense 29, la règle 32, l'aiguille 33 ainsi que d'autres équipements peuvent par ailleurs, être portés par un chariot 34 qui a la particularité de rouler directement sur les rails 1 et 20 ou sur la chaussée 16 tout en étant guidé par les rails 1 et 20. Si la voie ferrée ne doit pas être réalisée dans une tranchée 15 mais, en élévation seulement au-dessus d'une semelle 13 existante, le chariot 34 portera également des coffrages latéraux. Dans ce cas, le type du béton utilisé sera tel qu'après glissement du coffrage, sa tenue soit suffisante pour ne pas s'effondrer.Exemption 29, rule 32, needle 33 and others equipment can also be carried by a carriage 34 which has the special feature of driving directly on rails 1 and 20 or on roadway 16 while being guided by rails 1 and 20. If the track should not be made in a trench 15 but, in elevation only above of an existing sole 13, the carriage 34 will also carry formwork lateral. In this case, the type of concrete used will be such that after sliding the formwork, its holding is sufficient not to collapse.

Il ressort de cette manière de faire, que l'opération de mise à niveau de la chaussée sur les bords du rail enrobé, peut être effectuée en une passe. Notamment, la position de l'entretoise 21 sera suffisamment profonde pour que l'aiguille vibrante 33 puisse passer au-dessus pour l'accrocher. De même, dans le cas où la couche de revêtement doit être réalisée différemment de la couche de roulement, la masse 31 est réglée à un niveau inférieur à la surface définitive pour permettre la mise en place ultérieure de la couche de revêtement.It follows from this way of doing things, that the operation of updating level of the roadway on the edges of the coated rail, can be carried out a pass. In particular, the position of the spacer 21 will be sufficient deep so that the vibrating needle 33 can pass over it to hang it. Likewise, in the case where the coating layer must be produced differently from the wearing course, the mass 31 is adjusted to a level below the final surface to allow placement subsequent coating layer.

Pour diverses raisons, il pourra être requis d'enlever les tiges filetées 10, et éventuellement les entretoises 21. Cependant, on constate que le rail porte par sa semelle 5 directement sur la masse de béton sous-jacente. Par conséquent, il n'y a pas de risque de constitution de point dur à l'endroit où les corbeaux 8 sont fixés aux berceaux 7. Dans ces conditions, l'enlèvement des tiges 10 et entretoises 21 n'est pas indispensable. Les supports 10 et 21 sont en fait provisoires, même s'ils ne sont pas enlevés parce qu'à terme ils ne contribuent que très peu au maintien des rails. Ce maintien est assuré par le béton l'environnant.For various reasons, it may be necessary to remove the rods threaded 10, and possibly the spacers 21. However, it can be seen that the rail carries by its sole 5 directly on the underlying concrete mass. Consequently, there is no risk of a hard point being formed. the place where the crows 8 are fixed to the cradles 7. Under these conditions, the removal of rods 10 and spacers 21 is not essential. The supports 10 and 21 are in fact temporary, even if they are not removed because ultimately they contribute very little to the maintenance of the rails. This maintenance is ensured by the surrounding concrete.

Les figures 2a et 2b montrent une phase préalable préférée de réalisation de l'enrobage du rail 1. L'enrobage 2 se présente sous la forme d'un profil ayant, sensiblement, la forme définitive qu'il doit avoir autour du rail. Dans une première phase, on écarte les flancs 3 et 4 de l'enrobage 2. On peut néanmoins livrer sur le chantier un profil d'enrobage déjà écarté au repos.Figures 2a and 2b show a preferred preliminary phase of realization of the coating of the rail 1. The coating 2 is in the form a profile having, substantially, the final shape which it must have around the rail. In a first phase, the sides 3 and 4 are removed from the coating 2. It is nevertheless possible to deliver on the site a coating profile already discarded at rest.

Dans ces conditions, les ailes 35 et 36 du piétement du rail 1 sont introduites dans des cavités respectivement 37 et 38 de l'enrobage 2. Ceci étant réalisé, on referme l'enrobage 2 en appuyant sur les flancs 3 ou 4. Au besoin, on utilise des cerclages 380 en PVC ou en fer, du type de ceux utilisés dans le domaine de l'emballage. Ces cerclages seront perdus par la suite. On en coupera la partie supérieure.Under these conditions, the wings 35 and 36 of the base of the rail 1 are introduced into cavities 37 and 38 respectively of the coating 2. This being carried out, the coating 2 is closed by pressing on the sides 3 or 4. Au need, we use 380 PVC or iron straps, of the type of those used in the packaging field. These straps will be lost by the after. We will cut the upper part.

La figure 2b montre un atelier de réalisation de l'enrobage du rail. Une section 39 déjà enrobée repose sur des tréteaux 40. Une section à enrober 41 présente une continuité avec le rail de la section 40, notamment par soudage de tronçons de rail. Un tronçon 42 d'enrobage est mis en oeuvre, conformément à la description de la figure 2a. Une fois cette mise en place effectuée, ou au cours de cette mise en place, le tronçon 42 est repoussé vers le tronçon 40 de manière à minimiser les fuites. Au besoin, la section apparente 43 entre les tronçons 40 et 42, peut être munie d'une colle pour assurer la continuité de l'enrobage. A l'autre extrémité, le rail 1 est porté par des tréteaux 44. Puis on déplace l'atelier pour un tronçon suivant.Figure 2b shows a workshop for coating the rail. A section 39 already coated rests on trestles 40. A section with coating 41 has continuity with the rail of section 40, in particular by welding sections of rail. A coating section 42 is put in work, as described in Figure 2a. Once this setting place performed, or during this establishment, the section 42 is pushed back towards section 40 so as to minimize leaks. If necessary, the visible section 43 between sections 40 and 42, can be provided with an adhesive to ensure the continuity of the coating. At the other end, the rail 1 is worn by trestles 44. Then the workshop is moved for a next section.

La figure 3 montre un exemple de forme particulière de l'enrobage 2 dans lequel celui-ci est réalisé sous forme de plusieurs sections emboítables. L'enrobage 2 peut comporter ainsi une première partie 45 formant le flanc d'un côté et la semelle d'enrobage. Il comporte également deux autres parties 46 et 47. La partie 46 a un profil qui doit épouser la forme du rail 1. Elle présente une forme globalement plane pour venir combler juste l'espace situé en dessous du champignon 48 du rail 1. La troisième partie 47 vient compléter la forme globale de l'enrobage pour qu'elle soit du même type que celle vue précédemment. Les parties 46 et 47 forment ainsi des clés dont l'enlèvement ultérieur permet d'enlever le rail 1 pour le remplacer.Figure 3 shows an example of a particular form of the coating. 2 in which this is produced in the form of several sections nestable. The coating 2 can thus comprise a first part 45 forming the sidewall on one side and the coating sole. It also includes two other parts 46 and 47. Part 46 has a profile which must follow the shape of rail 1. It has a generally flat shape to just fill the space below the head 48 of the rail 1. The third part 47 completes the overall shape of the coating so that it is the same type as the one seen previously. Parts 46 and 47 thus form keys whose subsequent removal makes it possible to remove the rail 1 to replace it.

L'enlèvement s'effectue de la manière suivante: la partie 47 est relevée verticalement selon une direction 49. Ensuite, la partie 46 est déplacée latéralement selon une direction 50 avant d'être également élevée selon la direction 49. Une fois les parties 46 et 47 enlevées, le rail 1 peut être lui-même enlevé par une élévation et éventuellement une légère rotation.The removal is carried out as follows: part 47 is raised vertically in a direction 49. Then, the part 46 is moved laterally in a direction 50 before being also elevated in direction 49. Once the parts 46 and 47 have been removed, the rail 1 can be itself removed by an elevation and possibly a slight rotation.

La figure 2a montre également des percements éventuels pouvant être réalisés de place en place dans le rail 1. En correspondance, l'enrobage 2 comportera des excroissances. Par ailleurs, l'enrobage 2 peut comporter des motifs en relief par rapport à son profil. Par exemple, l'enrobage 2 peut avoir une forme avec des ailes 51 et 52 pour être maintenu correctement sur et au fond dans la masse de béton. Les ailes 51 et 52 peuvent être réalisées sur des éléments d'enrobage avec clé ou sur les éléments d'enrobage normaux.Figure 2a also shows possible openings that can be made from place to place in rail 1. Correspondingly, the coating 2 will include growths. Furthermore, coating 2 may comprise patterns in relief relative to its profile. For example, coating 2 can have a shape with wings 51 and 52 to be properly maintained on and at the bottom in the mass of concrete. Wings 51 and 52 can be made on coating components with key or on coating components normal.

Lorsque l'enrobage 2 est réalisé en plusieurs parties, il est possible de tirer avantage de cette particularité et de disposer d'un profilé clé pour forcer le serrage des lèvres de l'enrobage sur la forme de maintien 31 après séchage de cette forme. Avec de tels profilés démontables, on peut ainsi renforcer le maintien des rails après la prise. Par exemple la partie 47 permet une expansion horizontale à l'endroit de la flèche 50.When coating 2 is made in several parts, it is possible to take advantage of this feature and have a key profile to force tightening of the lips of the coating on the holding form 31 after drying this form. With such removable profiles, you can thus strengthening the maintenance of the rails after setting. For example part 47 allows horizontal expansion at the location of arrow 50.
