FIELD: construction, road engineering. ^ SUBSTANCE: invention relates to rail transport, namely to superstructure of track, elements of rail joint. Sleeper gasket of intermediate rail joint is made of elastic material in the form of rectangular plate with holes for location of fixture elements and slots between figures of surface elements. Gasket is arranged between sleeper and gasket. Upper surface of gasket is arranged as double-level and contacts with gasket. The first level represents hexahedrons, and the second level represents cylindrical ledges with spherical end surface. Hexahedrons are limited by slots brought out to periphery and are arranged with identical cross section and specified pitch. Ledges are arranged with specified pitch and size and are inscribed into hexahedron. ^ EFFECT: invention provides for increased reliability of fixture and working resource of rail tracks, due to two various characteristics of gasket surface rigidity. ^ 2 cl, 3 dwg |
