Method for producing a substructure for a track for rail vehicles

摘要

In a method for producing a substructure for a track for rail vehicles which runs at the same height as the individual motor-vehicle traffic, provision being made under each of the rails forming the track for a load-bearing foundation, for example a sleeper, a concrete slab, a rigid beam or the like, to which the rail is fastened, for each rail (2, 19) a channel (3, 16) running in the longitudinal direction of the rail is produced, the width (B1) of which is greater than the width (B2) of the rail foot - or if components are provided under or against the rail foot, being greater than the width (B3) or the extreme distance of these components from one another - and the height (H) of which corresponds approximately to the distance from the bottom edge of the rail foot - or the distance from the bottom edge of the components provided under or against the rail foot - up to the top edge of the rail (2, 19). The foundation is then aligned by packing, underlaying or the like. Thereafter, the spaces on both sides of the rail (2, 19) are filled up to the walls of the channel (3, 16) and approximately up to the bottom edge of the rail head with filling bodies (5), bulk material (28) or the like. Finally, the spaces above the filling bodies (5), the bulk material (28) or the like are filled with a waterproof, preferably permanently elastic casting compound (8, 29). <IMAGE>
