Embedded floating slab vibration isolation track structure for continuously supporting steel rails and inhibiting steel rail corrugation
The invention relates to an embedded type floating slab vibration isolation track structure for continuously supporting a steel rail for inhibiting steel rail corrugation, which comprises a track bed foundation (5), elastic supports (4), a vibration mass roadbed slab (3), an embedded type steel rail continuous supporting elastomer (2) and the steel rail (1), and the vibration mass roadbed slab (3) is connected with the track bed foundation (5) through the discretely distributed elastic supports (4); the upper surface of the vibration mass roadbed slab (3) is provided with a steel rail groove extending along the longitudinal direction of the track, and the steel rail (1) is fixed in the steel rail groove through the embedded steel rail continuous supporting elastic bodies (2) which are continuously distributed. Compared with the prior art, the problems of steel rail Pinned-Pinned resonance and steel rail undulation abrasion of a floating slab ballast bed system in the prior art are solved, and the problems that an existing floating slab ballast bed system is poor in dynamic stability, large in ballast bed slab stress, large in ballast bed slab and steel rail noise radiation, large in fastener structure maintenance amount and the like are solved.
本发明涉及一种抑制钢轨波磨埋入式连续支撑钢轨的浮置板隔振轨道结构，包括道床基础(5)、弹性支承(4)、参振质量道床板(3)、埋入式钢轨连续支撑弹性体(2)、钢轨(1)，所述的参振质量道床板(3)通过离散分布的弹性支承(4)与道床基础(5)连接；参振质量道床板(3)上表面设置有沿轨道纵向延伸的钢轨凹槽，钢轨(1)通过连续分布的埋入式钢轨连续支撑弹性体(2)固定于所述钢轨凹槽中。与现有技术相比，本发明解决了现有技术中浮置板道床系统钢轨Pinned‑Pinned共振及钢轨波浪磨耗问题，以及现有浮置板道床系统动态稳定性差、道床板应力偏大、道床板及钢轨噪声辐射大、扣件结构维修量大等问题。
