METHOD OF FASTENING CONTINUOUS WELDED RAIL LENGTH OF BRIDGES

railway transport; permanent ways. SUBSTANCE: according to proposed method rail lengths are rigidly secured on section in zone of fixed end of each bridge superstructure and on the other section of each superstructure rail lengths are secured to provide displacement of superstructure relative to rail lengths. Novelty is that special fixing devices are installed on rail lengths of said other section of each bridge superstructure. Said fixing devices are arranged at both sides of under-rail bases along rail way at distance from under-rail bases preventing engagement of fixing devices with corresponding under-rail base at longitudinal shifts of bridge superstructure. Proposed method ensures prevention of formation of inadmissible clearance in case of bending of rail length, increase in bridge length of which continuous welded rails can be. EFFECT: enlarged range of laying of continuous welded rails on bridges and reduced cost of maintenance of rails and bridge members. 2 dwg
