Prefabricated vibration reduction ballast bed
The invention relates to the technical field of rail transit, in particular to a prefabricated vibration reduction ballast bed. The prefabricated vibration reduction ballast bed comprises a pluralityof prefabricated ballast bed blocks sequentially arranged in the extending direction of the vibration reduction ballast bed and prefabricated sleepers inserted between every two adjacent prefabricatedballast bed blocks, and each prefabricated ballast bed block is of a strip-shaped structure extending in the width direction of the ballast bed. The prefabricated ballast bed blocks are detachably connected with a base of the vibration reduction ballast bed, and elastic cushions are arranged between the prefabricated ballast bed blocks and the prefabricated sleepers. According to the prefabricated vibration reduction ballast bed, the prefabricated sleepers and the prefabricated ballast bed blocks which are small in longitudinal size are adopted, so that transportation and installation are facilitated, and the construction difficulty is reduced; and during maintenance, disassembly and replacement can be facilitated under the condition that normal operation is not affected.
本公开涉及轨道交通技术领域，尤其涉及一种预制减振道床。所述预制减振道床包括沿所述减振道床的延伸方向依次设置的多块预制道床块，以及插设在相邻的两块预制道床块之间的预制轨枕，所述预制道床块采用沿所述道床的宽度方向延伸的条形结构，所述预制道床块与所述减振道床的基底可拆卸式连接，所述预制道床块和所述预制轨枕之间设置有弹性垫。该预制减振道床通过采用纵向尺寸较小的预制轨枕和预制道床块，以方便运输与安装，并降低施工难度；在维护保养时，可以在不影响正常运营的情况下方便拆卸和更换。
