HIGH-SPEED RAILWAY TRACK SUPERSTRUCTURE DESIGN AND METHOD OF ITS CONSTRUCTION Russian patent published in 2024 - IPC E01B2/00 

FIELD: railway transport.

SUBSTANCE: invention relates to the field of railway transport, in particular to the structures of the superstructure of the ballastless railway track and can be used to create a high-speed railway. High-speed railway track superstructure comprises support plates on which the support blocks are mounted including lengthwise support beams arranged along the rail directly under it and crosswise load-bearing webs. Said support blocks are mounted on said support plates by threaded connection by means of rods, twice orthogonally bent while maintaining parallelism of axes of threaded parts of rods, which pass through said transverse load-bearing webs and are fixed in support plates in anchor devices installed in the body of support plates. Position of support blocks relative to support plates is fixed and fixed against movements relative to each other by inserts which are plastic during installation and hardening during mounting, installed between inner walls of support blocks and stops of support plates and between rectangular cutouts of longitudinal support beams and upper surface of support plates. In the body of the support blocks there installed are adjustment units, the upper platform of the longitudinal support beams is covered with sheet metal, and the rail foot is recessed into the upper platform of the longitudinal support beams. Rail lines have a detachable connection to each other by means of a thermal expansion compensation unit. Invention also relates to a method of constructing a high-speed railway track.

EFFECT: possibility of creation of design of superstructure of high-speed railway track with high operational properties, namely high reliability and speed of its assembly/disassembly.
