METHOD FOR UNINTERRUPTED PATH STRINGS LAYING WITH THEIR EXTENSION, BY WELDING AND ENTERING INTO OPTIMAL FIXATION TEMPERATURE Russian patent published in 2020 - IPC E01B29/17 

FIELD: rail vehicles.

SUBSTANCE: invention relates to the railway track superstructure, in particular to the continuous strings laying methods. Strings to be replaced are arranged in track. Distance between the ends of the strings corresponds to the required elongation of each of the strings for their introduction into the optimum fixing temperature. Ends of installed strings are pulled by straps. Road is prepared for removal of inventory rails laying in track. Then ends of the first pair of newly laid strings are joined to ends of strings lying in the path, and the strings are replaced with laying of paired plates. Ends of laid strings are welded together with ends of straddling strings. Control sections are laid on sleepers and laid strings. Ends of previously laid strings and laid pair of strings are heated to coincide with control sections of strings and sleepers. Strings are fixed on sleepers and paired plates are removed. Position of the ends of the laid pair of strings is fixed, after which the laying process is repeated for the next pairs of strings.

EFFECT: higher reliability of strings laying.
