Abstract RU 2733595 C1

FIELD: construction.

SUBSTANCE: invention relates to railway track superstructure, including to upper track structure in subway tunnel. Top structure of track comprises monolithic concrete tunnel base, under-rail reinforced concrete plates and rails. Rails are attached to reinforced concrete slabs by rail fasteners. Under-rail reinforced concrete plates rest on monolithic concrete tunnel base by means of two groups of elastomer mats – bearing and side mats-fillers. Rigidity of load-carrying mats is higher than stiffness of filler mats.

EFFECT: reduced level of vibration and structural noise.
