Composite material sleeper and preparation method thereof
The invention provides a composite material sleeper and a preparation method thereof.The composite material sleeper comprises a metal frame, the metal frame comprises an inner-layer frame and an outer-layer frame, concrete materials are arranged between the inner-layer frame and the outer-layer frame, the metal frame divides an inner cavity of the sleeper into vibration reduction areas and weight reduction areas, the vibration reduction areas are arranged at the positions close to the two ends, and the weight reduction areas are arranged at the positions close to the two ends. A steel rail fixing part is arranged at the top of the vibration reduction area, a vibration reduction module is installed in the vibration reduction area on the lower portion of the steel rail fixing part, the weight reduction area is arranged at the position close to the middle, and a resin concrete composite material is poured in the weight reduction area. The concrete material fully guarantees the strength of the sleeper, the resin concrete composite material reduces the overall weight of the sleeper, construction is convenient, shrinkage cracks are reduced, the mechanical property is good, and compared with a common concrete sleeper, the strength and elasticity are improved, and steel rail vibration is effectively buffered and conducted.
本发明提供一种复合材料轨枕及其制备方法，包括金属框架，所述金属框架包括内层框架和外层框架，所述内层框架和外层框架之间设置混凝土材料，所述金属框架将轨枕内部空腔分为减振区和减重区，所述减振区设置在靠近两端的部位，所述减振区的顶部设置钢轨固定部，在所述钢轨固定部下部的减振区内安装减振模块，所述减重区设置在靠近中间的部位，在所述减重区内浇筑树脂混凝土复合材料。混凝土材料充分保证轨枕的强度，树脂混凝土复合材料降低轨枕整体重量，便于施工，减少干缩裂缝，力学性能好，与普通混凝土轨枕相比，提高强度和弹性，有效缓冲和传导钢轨振动。
