Train through will frequently possessed dynamic intermittent combination of impact load and contraction stress, elastic cushion is applied to convex frantic jumble track spacing vertical plane, convex and buried in concrete, which can effectively limit lateral force transfer orbit system, guarantee the safety of train operation. The elastic cushion layer of the steel plate is based on the introduction of the German kalinberg S70 technology, which is designed by the structure and rubber formula, which is suitable for the high iron products in China.
