FIELD: transportation.SUBSTANCE: invention relates to methods of longitudinal movement (creep) of sections of jointless rail track. Method for assessing the rail stalk creep consists in the fact that on each reference sleeper and rail stalk, on the non-working side of the rail and at a known distance from each other, there are installed beacons - ferromagnetic elements so as to provide reliable detection of signals from them with the help of a magnetic flaw detector. Invention presupposes measurement of a time mismatch between beacons and determination of the distance between them. Rail stalk creep is evaluated by comparing the current distance between beacons with results of previous measurements taking into account the allowable value limit, as well as by comparing rail creepings on nearby reference sleepers.EFFECT: higher accuracy and reliability of evaluation of rail stalk creep.1 cl, 3 dwg |
