FIELD: construction.
SUBSTANCE: invention relates to construction of railway track in tunnels, in particular, to methods of construction of vibration isolating base of superstructure of subway track. Method includes the stage of installation of vibration isolators with forms on the lower structure of the track. Transverse support plates are pre-laid on vibration isolators. Plates contain rectangular narrow part, rectangular wide part and trapezoidal part. Trapezoidal part connects rectangular parts. Plate is lifted to the design height and positioned horizontally. Then the transverse plate is fixed by pouring the gravy mixture into the mounting holes of the plate. At the stage of preliminary laying, orientation of plates is alternated by 180° relative to adjacent so that rectangular narrow part of each support plate adjoins rectangular wide part of neighbouring plates. Resilient seals are arranged between fixed plates.
EFFECT: reduced intensity of vibration from passing rolling stock.
