NOVELTY - The utility model claims a railway track mechanism for preventing leakage of track circuit, comprising a rail and a rail sleeper, two sides of the rail is provided with a rail gauge baffle, the surface of the rail gauge baffle is fixedly connected with an elastic strip through a spiral spike, the rail gauge baffle is fixedly connected with the bottom of the rail by the elastic strip, the rail bottom of the rail, the surface of the rail waist and the rail bottom slope is sprayed with an insulating coating. The utility model graphene the insulating anti-corrosive paint to the rail bottom of the rail, rail waist and rail bottom slope part spraying the rail with anti-corrosion, insulating effect, not affecting the ultrasonic flaw detection, using polyurethane rigid foam and continuous alkali-free fibre composite rail sleeper made of insulating material for supporting the steel rail, even if there are these scattered coal ash, rail and brake shoe abrasion of iron powder, sanding of locomotive, the dust of the ballast, will not affect the rail circuit characteristics the whole mechanical property is good.
