Box-type roadbed structure with active vibration isolation performance and construction method
The invention discloses a box-type roadbed structure with active vibration isolation performance and a construction method, and relates to the field of active vibration isolation of high-speed railway roads.The box-type roadbed structure comprises short piles, the short piles are vertically buried in foundation soil, the upper surfaces of the short piles are provided with wave resistance plates, the wave resistance plates are horizontally buried in the surface layer of a foundation, and the upper surfaces of the wave resistance plates are horizontally provided with bottom plates; a vertical plate is vertically placed on the upper surface of the bottom plate. The wave resistance plate with the groove and the groove hole is additionally arranged on the lower portion of the box-type roadbed, the groove hole is formed in the wave resistance plate and used for being filled with glass wool, the groove is formed in the surface of the wave resistance plate and used for containing the rubber cushion layer, and through the two vibration reduction and isolation measures, the wave resistance plate can weaken vibration of the box-type roadbed structure and reduce downward transmission of vibration, so that the vibration reduction effect is good. The short piles connected with the bottom plate not only can prevent vibration from spreading into foundation soil and play a role in protecting surrounding buildings, but also can improve the integrity and stability of the box type roadbed structure in the running process of a train.
本发明公开了一种具有主动隔振性能的箱式路基结构及施工方法，涉及到高速铁路路基主动隔振领域，包括短桩，短桩竖向埋置于地基土中，短桩的上表面设置有波阻板，波阻板水平埋设在地基表层，波阻板的上表面水平放置有底板，底板的上表面竖直放置有竖板。本发明箱式路基下部加了带凹槽和槽洞的波阻板，该波阻板内部有槽洞用于填充玻璃棉，波阻板表面有凹槽，用于放置橡胶垫层，通过这两种减隔振措施，波阻板既可以减弱箱式路基结构自身的振动，又可以减少振动向下传播，与底板相连接的短桩，既可以阻挡振动向地基土中传播，对周围筑物起到了保护作用，又可以提升列车运行过程中箱式路基结构的整体性和稳定性。
