VIBRATION ISOLATING BASE OF SUPERSTRUCTURE OF SUBWAY TRACK Russian patent published in 2024 - IPC E01B1/00 E01B2/00 E01B3/40 

FIELD: construction.

SUBSTANCE: invention relates to the field of railway track structure in tunnels, in particular, to the subway track superstructure vibration isolating bases. Base comprises multiple transverse support plates with rail supports. Plates are installed on vibration isolators. Each transverse support plate comprises a rectangular narrow part connected to an expanding trapezoidal part connected to a rectangular wide part. Rectangular narrow part of each support plate is installed so that it is in contact with two rectangular wide parts of adjacent transverse support plates. Under rectangular narrow part on longitudinal axis there is one vibration isolator, and under rectangular wide part at equal distance in longitudinal axis there are two vibration isolators. Vibration isolators are located on two parallel longitudinal lines at the same longitudinal distance from each other.

EFFECT: reduced intensity of vibration from passing rolling stock.
