| Zusammenfassung: | The invention provides a special-shaped steel rail which comprises a rail head 11, a rail waist 12 and a rail bottom 13. The steel rail further comprises an arch slope 14 protruding out of the surface of the steel rail. The invention further provides a steel rail glue joint insulating joint. The insulating joint comprises two special-shaped steel rails connected in series. By means of the glue joint insulating joint, a large rail seam does not occur on the connection portion of the two steel rails connected in series. Besides, the probability that the steel rail glue joint insulating joint is damaged by temperature stress and train impact and accordingly fails can be substantially reduced. The steel rail glue joint insulating joint can fully resist temperature stress changes of a seamless line and impact force generated during running of a train, and development requirements of the trans-section seamless line are met. |
