Sleepers are also called sleepers and are one type of railway fittings. The material is not only wood, so the sleeper is more scientific. The sleepers are required to support the rails, maintain the position of the rails, and transmit the large pressure transmitted by the rails to the track bed. It must have a certain flexibility and elasticity. When the train passes by, it can be properly deformed to buffer pressure, but the train must be recovered as far as possible after passing.

The prior Chinese patent with the granted publication number of CN1376831A discloses a high-speed railway sleeper capable of resisting horizontal vertical vibration, which comprises a bottom plate, a lower seat on a figure point, a lifting seat in threaded connection with the lower seat, a spherical support arranged on the lifting seat and matched with a lifting spherical surface, a spherical solid arranged on the spherical support and matched with the spherical surface of the spherical support to lay a rail on the upper surface of the spherical solid, and a transverse vibration resisting sleeve connected with a nut arranged on the base.

Although the technical scheme can buffer horizontal and vertical vibration of the sleeper to a certain extent, the buffering effect is poor, the spherical solid body matched with the rail is inconvenient to install, the processing technology of the spherical support is complex, and the production cost of enterprises can be increased. Therefore, we propose a high speed railway sleeper resistant to horizontal vertical vibration.
