Patent

CA 2247039

On a railway track comprising a ballast bed (10), sleepers (12) provided on the ballast bed and tracks (14) mounted on the sleepers, the sleepers are disposed closely adjoining one another but out of mutual contact, leaving a gap, the sleepers defining drainage channels (134) extending transversely to the longitudinal direction of the track for lateral water drainage. The gaps between the sleepers may be covered by covering elements (142) or the sleepers may overlap without touching one another. In this manner the track bed is substantially kept free of water, the positional stability of the track is increased, therefore reducing or rendering superfluous the normally required maintenance work such as tamping as well as cleaning and weed control.

L'invention concerne une voie ferrée comportant un lit de ballast (10), des traverses (12) placées sur ledit lit de ballast et des rails (14) fixés sur les traverses. Les traverses sont placées très proches les unes des autres, mais sans contact, avec un espace entre elles et définissent des galeries d'évacuation des eaux transversales au sens longitudinal de la voie, qui servent à évacuer latéralement l'eau. Les espaces situés entre les traverses peuvent être recouverts d'éléments de recouvrement (142) ou les traverses peuvent se chevaucher sans contact. La couche de forme est ainsi maintenue hors de portée de l'eau et la stabilité de positionnement de la voie est augmentée. Les travaux d'entretien indispensables, tels que le bourrage, le nettoyage et l'arrachage des mauvaises herbes sont de ce fait réduits ou deviennent superflus.
