Concrete-filled steel tube elastic sleeper and preparation method thereof
The invention discloses a concrete-filled steel tube elastic sleeper and a preparation method thereof, and belongs to the field of ballastless track concrete sleeper structures, the concrete-filled steel tube elastic sleeper comprises a concrete-filled steel tube sleeper and an anti-vibration pad arranged on the periphery of the concrete-filled steel tube sleeper so as to isolate the concrete-filled steel tube sleeper from concrete in a ballast bed, and the invention further provides three preparation methods. The preparation method comprises the steps that a corresponding anti-vibration pad is prefabricated, then the anti-vibration pad wraps a sleeper structure, the sleeper structure is placed in a mold for pouring and demolding to form the elastic sleeper, and rapid preparation is conducted through an assembly line workshop, and the three preparation modes meet the large-scale preparation requirement of the elastic sleeper. According to the concrete-filled steel tube elastic sleeper and the preparation method thereof, the concrete-filled steel tube elastic sleeper can be suitable for the field of existing ballastless tracks, stress concentration between the sleeper and a ballast bed is reduced, the friction effect between steel tube vibration and ballast bed concrete is relieved, the service life of the sleeper is greatly prolonged, and large-scale production is easy; good popularization values are realized.
本发明公开了一种钢管混凝土弹性轨枕及其制备方法,属于无砟轨道混凝土轨枕结构领域,包括钢管混凝土轨枕和设置在其外周设置减振垫,以将钢管混凝土轨枕与道床内的混凝土相隔绝,且还提供了三种制备方法,其包括了预制对应的减振垫再将减振垫包裹在轨枕结构上、通过将轨枕结构放置在模具中进行浇筑脱模形成弹性轨枕以及通过流水线车间进行快速制备的制备方法,上述三种制备方式满足弹性轨枕大规模的制备需求。本发明所提供的钢管混凝土弹性轨枕及其制备方法,其可适用于现有的无砟轨道领域,降低了轨枕与道床之间的应力集中,减轻了钢管振动与道床混凝土之间摩擦效应,使得轨枕使用寿命大幅度提升,且易于大规模生产,具有良好的推广价值。
