METHOD OF REINFORCEMENT OF END PARTS OF REINFORCED CONCRETE SLEEPERS BY ADDITIONAL REINFORCEMENT WITH SPIRALS

摘要

FIELD: railway construction.;SUBSTANCE: invention relates to railway track superstructure, namely to methods of making concrete sleeper sleeper. End parts of the reinforced concrete sleeper are additionally reinforced with spirals. Spiral is made in the form of a cone, at that the smaller diameter of the spiral is fixed on butt end caps of the sleeper accessories.
