Abstract
The present invention relates to a seamless connection method for railway rails. When rails are rolled in a hot mode, an end head moulding method or other processing methods are adopted, the two ends of the rails are processed into butt joints corresponding to each other in a concave and convex mode or in a parallel mode and are connected by the existing or improved fishplate to make the butt joint position compensated in the longitudinal direction, guarantee the always longitudinal continuation of the rails on the aspect of structure and eliminate joints penetrating cross section, which effectively avoids vibration and noise generated by the impact of the rails and correspondingly improves butt joint strength and butt joint rigidity. The present invention is suitable for high-speed railways laid by long rails and short rails and is favorable for exerting the superiority of the short rails, such as low cost on the aspects of manufacture, transportation, construction, etc., and safer and more reliable joints of the short rails.
