Abstract
Description
L'objet de cette invention est la voie ferree, appliquée aux voies de tramway. The object of this invention is the railway, applied to tramways.
La voie ferrée connue est constituée de la structure ferroviaire ainsi que de l'assiette de voie établie. La structure ferroviaire est constituée des rails fixés sur des supports, formés de traverses en bois ou bien de traverses en béton, encastrées sur le ballast, ainsi que sur l'assiette de voie établie. The known railway consists of the railway structure as well as the established track base. The railway structure consists of rails fixed on supports, formed of wooden sleepers or else of concrete sleepers, embedded on the ballast, as well as on the established track base.
La faiblesse d'une telle voie, ce sont les frais d'exploitation importants, résultant de la nécessité de nombreux nettoyages et du ravitaillement en ballast. Tandis que si l'assiette de la voie n'est pas établie, elle subit différentes déformations, considération faite de l'infiltration dans l'assiette des eaux pluviales, qui s'infiltrent à travers le ballast. The weakness of such a route is the significant operating costs, resulting from the need for numerous cleanings and ballast refueling. While if the attitude of the track is not established, it undergoes different deformations, taking into account the infiltration in the attitude of rainwater, which infiltrates through the ballast.
Il y a des voies ferrées connues dans lesquelles les supports sont constitués de panneaux, qui sont fabriqués en béton arm. Les panneaux sont fabriqués sur place ou bien ils sont préfabriqués par coulage de béton en moule. There are known railways in which the supports consist of panels, which are made of reinforced concrete. The panels are manufactured on site or they are prefabricated by pouring concrete into molds.
Un tel panneau dans la structure ferroviaire est encastré dans la couche intermédiaire en matière élastique, ce qui améliore l'élasticité de la structure ferroviaire, laquelle par ailleurs est encastrée sur l'assiette de la voie établie. Such a panel in the railway structure is embedded in the intermediate layer of elastic material, which improves the elasticity of the railway structure, which moreover is embedded on the base of the established track.
Le défaut d'une telle structure ferroviaire réside dans le fait que le panneau lourd et rigide en béton armé est affaibli par l'application d'une construction à plusieurs couches, en alternance avec des couches élastiques. En outrez le panneau lourd en béton arme, par suite de l'affaissement dans l'infrastructure, occasionne de grandes difficultés dans l'exploitation et notamment dàns la mise de la voke en ligne de rappel. Le mouvement des panneaux a parfois pour résultat le dérangement de la structure ferroviaire. Dans certains supports, en tant que panneaux, ainsi que dans l'assiette de la voie apparaissent des fêlures transversales, provoquées par la chaleur.Etant donné que la majorité des fêlures thermiqueZs passent à travers le fixage des rails, ceci occasionne l'arrachement des fixages des rails. The defect of such a railway structure lies in the fact that the heavy and rigid reinforced concrete panel is weakened by the application of a construction with several layers, alternating with elastic layers. In addition to the heavy reinforced concrete panel, as a result of the subsidence in the infrastructure, causes great difficulties in operation and in particular when putting the voke on the recall line. The movement of the panels sometimes results in the disruption of the railway structure. In some supports, as panels, as well as in the attitude of the track appear transverse cracks, caused by the heat. Since the majority of thermal cracks Zs pass through the fixing of the rails, this causes the tearing of the rail fastenings.
La voie, selon la présente invention, possède un support en forme de polygone ouvert,dont la surface opposée par rapport à la base est brisée de façon qu'elle possède une pente qui assure l'écoulement des eaux pluviales, et elle possède également des nervures transversales de renforcement qui sont avantageuses dans les lieux de fixage des rails. Le support contient au morns-huit couches de toile métallique, avantageusement tissée à mailles en forme de polygone, il est renforcé de tiges de fer dans les nervures de renforcement et rempli de béton - ciment à grain fin mélangé à de la résine, tandis que l'intérieur du polygone du support est rempli d'un élastomère de polyuréthane et enfin les fronts aes supports de la structure ferroviaire sont rendus étanches avec du mastic elas- tique. The track, according to the present invention, has a support in the form of an open polygon, the surface opposite to the base is broken so that it has a slope which ensures the flow of rainwater, and it also has transverse reinforcing ribs which are advantageous in the places of fixing of the rails. The support contains eight layers of metallic fabric, advantageously woven with polygon-shaped mesh, it is reinforced with iron rods in the reinforcement ribs and filled with concrete - fine-grained cement mixed with resin, while the inside of the support polygon is filled with a polyurethane elastomer and finally the fronts of the support of the railway structure are sealed with elastic sealant.
En dehors de ceci, le support est encastré de façon démontable sur une assiette de voie établie, configuré de façon qu'il possède des porte-à-faux en butée qui protègent contre un déplacement transversal du support, tandis que l'espace entre les porte-à-faux en butée et la surface latérale du support est rempli avec du mastic élastique. Apart from this, the support is removably embedded on an established track plate, configured so that it has overhangs in abutment which protect against transverse movement of the support, while the space between the overhang in abutment and the lateral surface of the support is filled with elastic sealant.
Il est avantageux que le support possède au moines deux orifices pour l'introduction de l'élastomère de polyuréthane. It is advantageous that the support has at the monks two orifices for the introduction of the polyurethane elastomer.
Contormément à l'invention, la voie n'exige pas un entretien fréquent par suite de l'elimination du ballast; grâce à l'application de l'élastomère de polyuréthane, on a obtenu un amoindrissement du bruit par l'affaiblissement des vibrations, ce qui est d'importance s'il s'agit de voies franchissante des ponts, des viaducs et cela améliore les conditions d'exploitation du matériel roulant. Contrary to the invention, the track does not require frequent maintenance as a result of the elimination of the ballast; thanks to the application of the polyurethane elastomer, noise has been reduced by weakening vibrations, which is important in the case of crossings of bridges, viaducts and this improves the rolling stock operating conditions.
Ayant appliqué une armature réticulaire dispersée, on a obtenu un matériau homogène qui possède une grande résistance à la traction, résistant au fendillement, car le dépassement des contraintes n'évoque qu'un menu endommagement local, sans élargissement des fêlures sur les zones voisines du support. Having applied a dispersed reticular reinforcement, a homogeneous material was obtained which has a high tensile strength, resistant to cracking, because the exceeding of the constraints only evokes a small local damage, without widening of the cracks on the neighboring areas of the support.
Une telle armature dispersée permet d'obtenir une meilleure répartition des contraintes.Such a dispersed frame makes it possible to obtain a better distribution of the stresses.
La voie, selon cette invention, n'exige aucune application de ballast, ainsi que de traverses et elle est facile à utiliser dans l'exploitation par un démontage facile en cas d'abaissement de la ligne de rappel en améliorant la situation du support, ce qui aiminue le prix de l'entretien. The track, according to this invention, requires no application of ballast, as well as sleepers and is easy to use in operation by easy disassembly in case of lowering of the return line by improving the situation of the support, which reduces the cost of maintenance.
