Rail train noise-reduction bumpiness elimination steel rail and transition connecting method thereof
A rail train noise-reduction bumpiness elimination steel rail comprises a rail head, a rail web and a rail bottom. The steel rail is fixedly connected with the rail bottom through the rail web. The rail train noise-reduction bumpiness elimination steel rail is characterized in that the two end faces of the rail are not planes which are perpendicular to the axis in the extension direction of the rail, the shapes of the two end faces are complementary with each other, the two end faces can be connected with each other in a matched mode. A rail train noise-reduction bumpiness elimination steel rail transition connecting method comprises the step that multiple steel rails used in railway are sequentially in butt joint with one another in a head-to-tail mode, and small gaps exist between the butt joint portions. The rail train noise-reduction bumpiness elimination steel rail and the transition connecting method thereof have the advantages that the joint strength in not reduced, the practicability and the universality are achieved, the technology is simple, materials are not increased, the installation is the same as before, the steel rail is durable in use, good feasibility is achieved, and the popularization is facilitated.
