RAILWAY TRACK IN AREA ADJACENT TO MANMADE STRUCTURE Russian patent published in 2012 - IPC E01B1/00 

FIELD: construction.

SUBSTANCE: railway track in an area adjacent to a manmade structure comprises a section of a railway track laid onto a reinforced concrete base of a manmade structure and a section of a railway track adjacent to a manmade structure and laid onto an earth bed with a ballast layer that are serially arranged and joined. On the section of the railway track laid onto the earth bed there is a transition section with a reinforcement frame installed in a bed layer in the form of rows of spatial metal grids. The size of cells in spatial grids is made with the possibility for crushed stone to penetrate inside a spatial grid. At the outer side of the frame facing the edge of the earth bed the frame height is more to retain the slope part of the ballast prism against side thrusting and fall. The distance between the rows of a spatial grid reduces as the section of the railway track laid on the reinforced concrete base of the manmade structure is approached.

EFFECT: invention provides for smooth coupling, stiffness and minimised deformation of a track at the joint between a section of a railway track laid onto a reinforced concrete base of a manmade structure and a section of a railway track adjacent to a manmade structure and laid onto an earth bed with a ballast layer.
