Efficiency of reinforcement of transition sections on the railroad by the developed constructions

Abstract

The article gives the reasons of occurrence and origin of defects of railroad track structure elements on approaches to bridges. The defects arising on sleepers and intermediate fasteners of the track structure and the costs obtained as a result of early replacement of the track structure elements on the transition sections are calculated. As a result of the received constructive decision the technological process of driving of reinforced concrete piles in an embankment for the purpose of maintenance of safe and reliable work of sleepers and intermediate fastenings during service life in 3 m on a transition section is developed. As a result of implementation of the developed design in 1384 transition sections, the economic efficiency amounted to 447.638 million sums. As a result of reinforcement of the transition section, the cost of current and lifting repair of the track is reduced.
