Embodiment Construction
[0020] see figure 1 , showing the prefabricated track slab structure of the present invention with absorbing wheel-rail noise.
[0021] The prefabricated track slab structure with absorbing wheel-rail noise comprises a prefabricated slab 11, the structure and shape of the prefabricated slab 11 can be of a conventional type, the upper surface of the prefabricated slab 11 is provided with a steel rail 12, and the prefabricated slab 11 11 is integrally arranged in a groove of a base 13 , and a vibration damping pad 14 is provided between the prefabricated plate 11 and the groove of the base 13 .
[0022] Vibration between the prefabricated slab 11 and the abutment is eliminated comprehensively through the setting of the vibration damping pad 14. Optionally, the vibration damping pad 14 is located in the middle of the interval between the groove and the prefabricated slab 11, The two ends of the interval are provided with sealing devices to avoid the entry of external rainwater o...
