FIELD: road construction.
SUBSTANCE: invention relates to track superstructure, including track superstructure in subway tunnels. Device for protection of vibration-protective structure of upper structure of track contains two parts, one of which, upper, is made wavy in cross-section and is intended for attachment to vibration protection structure of upper structure of track, and the other, lower, part is made L-shaped in cross section and is intended for attachment to the tunnel structure. Upper part is overlapped with lower part, and in gap between them there is at least one resilient elastic element.
EFFECT: long-term efficiency of the vibration protective structure of the upper structure of the track; reliability of the vibration rupture is increased at provision of the possibility of movement of the vibroactive structure with its operating amplitude with exclusion of the possibility of ingress of foreign objects inside the vibration suture.
