METHOD FOR ARRANGEMENT OF BALLAST BASE OF RAILWAY TRACK AND DEVICE FOR ITS REALISATION

摘要

FIELD: construction.;SUBSTANCE: material of a track base, for instance, granite, is filled in an even layer with height of up to 300 mm from a hopper (4) onto metal reinforcement, for instance, a net (1) laid on the levelled earth. Then at least one laser (8) melts the filled layer. Lasers (8) are installed as capable of reciprocal or circular motion in the horizontal plane and are connected to a diesel generator of a self-propelled machine. Then a rotary water-cooled roller (10) is squeezed in the hardening melt of an indent (12) with depth of up to 100 mm and dimensions equal to the sleeper base. After cooling into the indents (12) sleepers are laid with ready rail sections.;EFFECT: increased strength and reliability of a railway track with appropriate increase of train motion speed.;2 cl, 1 dwg
