High-friction-force sleeper

The utility model relates to the technical field of sleepers, and discloses a high-friction-force sleeper which comprises a sleeper body, coarse aggregate is formed on the surface of the sleeper bottom of the sleeper body to be exposed, and the exposed coarse aggregate is stones in sleeper concrete raw materials. According to the high-friction-force sleeper, the mode that coarse aggregate at the bottom of the sleeper leaks outwards is adopted, the friction force between the sleeper and a ballast bed is increased, and therefore the transverse resistance of the sleeper is increased, the railway transportation requirement of China is met, and the problems or defects existing in a traditional railway concrete sleeper are effectively solved or overcome. 本实用新型涉及轨枕技术领域，公开了一种高摩擦力轨枕，包括轨枕本体，所述轨枕本体的枕底表面形成粗骨料外露，外露的粗骨料为轨枕混凝土原料中的石子。本实用新型所提供的一种高摩擦力轨枕采用枕底粗骨料外漏的方式，增大了轨枕与道床之间的摩擦力，从而增大了轨枕的横向阻力，满足了我国铁路运输要求，有效地解决了传统铁路混凝土轨枕存在的问题或不足。
