Embodiment Construction
[0023] The present invention firstly provides a special-shaped rail, which includes a rail head 11 , a rail waist 12 and a rail bottom 13 , and the rail also includes an arch 14 protruding from the surface of the rail. Preferably, the arch slope is located on the upper surface of the rail bottom.
[0024] In a specific implementation manner, the vertical cross-sectional shape of the arch slope in the length direction of the rail is trapezoidal. Preferably, the vertical cross-sectional shape of the arch slope in the rail length direction is isosceles trapezoidal, and the length of the upper bottom surface of the arch slope in the rail length direction is 20-70 mm, the height of the arch slope is 10-20 mm, and the arch slope The included angle between the slope and the bottom plane is 5-60°.
[0025] In a specific embodiment, the arch slope is arranged at a position between two adjacent bolt holes on the rail in the length direction of the rail. Preferably, the distance from t...
