Ballast mat for ballast track bed and track structure
The invention relates to the technical field of track traffic, and provides a ballast mat for a ballast track bed and a track structure, by adopting an upper, middle and lower three-layer structure, a foundation layer, a contact layer and a vibration reduction layer of the ballast mat are made of rock wool materials and are formed by compression molding according to the compaction density ratio of 1.2: 1: 1.2, it can be guaranteed that the ballast mat is not damaged in the using process, the service life of the ballast mat is prolonged, and the service life of the ballast mat is prolonged. The service life is prolonged. And the railway ballast mat is made of inorganic materials, does not contain any additive, and has excellent aging resistance, weather resistance and fire resistance. The volume of the rock wool fiber material can be compressed, extra space is not needed during deformation, groove design does not need to be carried out on the railway ballast mat, the situation that the vibration reduction performance of the railway ballast mat fails after dirt is mixed into grooves of the railway ballast mat in the using process is avoided, and the railway ballast mat can be effectively used for a long time in the railway environment.
本发明涉及轨道交通技术领域，提供一种用于有砟道床的道砟垫及轨道结构，通过采用上中下三层结构，将道砟垫的基础层、接触层和减振层采用岩棉材料并且以1.2：1：1.2的压实密度比例压制成型制成，能够保证道砟垫在使用过程中不被破坏，延长使用寿命。并且道砟垫采用无机材料制成，不含任何添加剂，具有优秀的耐老化性、耐候性和耐火性。岩棉纤维材料的体积可以压缩，变形时不需要额外的空间，不需要在道砟垫上进行沟槽设计，避免了在使用过程中道砟垫沟槽混入污垢后道砟垫的减振性能失效，能够在铁路环境中长期有效使用。
