Plastic track plate, preparation process thereof and railway track structure
The invention provides a plastic track plate. The plastic track plate comprises, by mass, 20-30% of plastic particles, 20-45% of synthetic resin, 30-40% of natural resin and 10-20% of additives. The invention further provides a preparation process of the plastic track plate. The preparation process comprises the steps of mixing, drying, injection molding, forming and the like. The invention further provides a railway track structure. The railway track structure comprises a foundation bed, a supporting layer, a damping layer, the plastic track plate and a steel rail which are sequentially laidfrom bottom to top. The plastic track plate is low in manufacturing cost, light in weight, short in manufacturing period, convenient to transport and easy to install, improves the construction efficiency, has better elasticity than a steel-concrete structure, can optimize the rigidity of a ballastless track system, facilitates optimization the dynamic response of a wheel track, can achieve the vibration and noise reduction effect, and reduces the maintenance workload.
本发明提供了一种塑胶轨道板，包括塑胶粒、合成树脂、天然树脂及添加剂，所述塑胶粒的质量百分比为20％～30％；所述合成树脂的质量百分比为20％～45％；所述天然树脂的质量百分比为30％～40％；所述添加剂的质量百分比为10％～20％；本发明还提供了一种塑胶轨道板的制备工艺，包括混料、烘干、注塑、成型等步骤，本发明还提供了一种铁路轨道结构，包括从下往上依次铺设的基床、支撑层、阻尼层、塑胶轨道板和钢轨。本发明中的塑胶轨道板不仅造价低，质量轻，制造周期短，运输方便又易于安装，提高了施工效率，而且弹性较于钢混结构更加优秀，可优化无砟轨道系统的刚度，有利于优化轮轨动态响应，并能起到减振降噪的作用，有利于减少养护维修工作量。
