The existing construction of Railways supports is based on ties, wood, concrete or prestressed concrete types, to which the two parallel rails are fastened, forming a Track, which is placed on the Ballast, selected material such as crushed stone and all together on the roadbed to hold the track in line and surface. This system is flexible and vulnerable to the dynamic action of vehicles in motion and to the climatic influences. The concentrated loads of the vehicles in motion are transfered directly to the ballast and to the roadbed. My invention is a solid reinforced concrete continuous tunnel type support of the Railway. The concentrated loads of the vehicles in motion are transfered by the reinforced concrete top slab to its side supporting reinforced concrete walls and to their foundations below the frost penetration level as a uniformly distributed loads.

Les voies ferrées existantes sont établies sur traverses en bois, en béton ou en béton précontraint déposées sur ballast, un matériau granulaire de type pierre concassé que l'on place sur la plate-forme de la voie pour maintenir les rails en bon alignement et nivellement. L'ensemble est flexible et vulnérable aux sollicitations dynamiques des véhicules en mouvement et aux conditions météorologiques. Les charges concentrées des véhicules sont transférées directement au ballast et à la plate-forme. La présente invention concerne un support de rail sous forme de profilé continu en béton armé. Les charges concentrées des véhicules en mouvement sont transférées par la dalle supérieure armée du support à ses flancs également en béton armé et à ses semelles établies sous le niveau de gel pour une distribution uniforme de la charge.
