FIELD: construction.SUBSTANCE: sleeper sole includes cogs. The cog height is reduced to 10-50 mm in the mid-part of sleeper bed, at distance equal to effective zone of compressing edge stress. Rail pad area does not have cogs. At the ends and partly in the middle of rail support sole where elongation stress is absent or insignificant, the cog height is increased to 30-100 mm.EFFECT: rated increase of rail support shearing force approximately in 10-15 times.2 dwg |
