FIELD: railway.
SUBSTANCE: invention relates to the construction of the superstructure of a railway track, in particular to methods for relieving temperature stresses in adjacent strands of a seamless track. In the process of calculating elongation, adjacent strands are divided into fifty meter sections. The calculated elongation risks are applied to the lashes and the anchor sections are calculated. The rail is laid with a shortening equal to the lengthening of both strands. A hydraulic tensioning device is installed at the junction of the shortened rail and the lash. Alternate forced input of adjacent lashes into the required temperature range is carried out.
EFFECT: reduced time interval of the technological process.
