METHOD OF JOINTLESS TRACK RAIL LENGTH LAYING IN CURVILINEAR RAILROAD SECTIONS

摘要

FIELD: railroad repairs. SUBSTANCE: method of jointless track rail length laying in curvilinear railroad sections provides, that one rail length and adjacent to it equalizing rails are laid inside track and other rail length and adjacent to it equalizing rails are laid outside the track. Changed rails are dismantled, end sections of rail length and equalizing rails are laid in project position and are fixed to avoid longitudinal motion. Middle sections of rail length are moved to under rail base to center or from center of curvilinear track section. In the case if movement is exercised from center of the section, then middle parts of rail length are heated before that, and if movement is exercised to center of the section, then middle parts of rail length before movement are cooled. EFFECT: improved quality of repairs.
