Rubber cast iron sleeper plate type vibration reduction system
A rubber cast iron sleeper plate type vibration reduction system comprises a steel rail, a fastener, a fastener base plate, a sleeper and a ballast bed. The sleeper is a cast iron sleeper, and the fastener base plate and the cast iron sleeper are integrally formed. Rubber vibration reduction pads are symmetrically arranged on the bottom surface of the sleeper, and the sleeper is provided with a rubber sheath which wraps the bottoms of the rubber vibration reduction pads and extends upwards to wrap the side surface of the sleeper. The ballast bed is arranged below the rubber sheath; the ballastbed is composed of a self-compacting mortar cushion layer or a common reinforced concrete cushion layer; and the self-compacting mortar cushion layer or the common reinforced concrete cushion layer is filled below the rubber sheath and around the side surface of the rubber sheath. Under a condition of the same mass, a volume of the vibration mass can be greatly reduced so that a purpose of greatly reducing a height of a track structure is achieved.
一种橡胶铸铁轨枕板式减振系统，包括钢轨、扣件、扣件垫板、轨枕、道床，所述的轨枕为铸铁轨枕，所述扣件垫板与所述铸铁轨枕一体成型；所述的轨枕底面对称设置橡胶减振垫，并且所述的轨枕设置橡胶包套包裹所述橡胶减振垫的底部并向上延伸到包裹所述轨枕的侧面；所述橡胶包套下设所述道床，所述的道床由自密实砂浆类垫层或普通钢筋混凝土垫层构成；所述自密实砂浆类垫层或普通钢筋混凝土垫层在所述橡胶包套下方及侧面四周填充。本发明在同样质量时，能够大幅度的降低参振质量的体积，从而达到大幅度降低轨道结构高度的目的。
