Regulation type ballast bed slab, ballast bed and construction method of ballast bed
According to the regulation type roadbed slab, the roadbed and the construction method of the regulation type roadbed slab, the regulation type roadbed slab is provided with the multiple regulation type vibration isolators, and the track slab is arranged on the base through the rubber springs of the multiple regulation type vibration isolators, that is, rigid connection between a track structure and a base structure is cut off in a point supporting mode; impact energy generated when a train runs is absorbed through the multiple rubber springs, and therefore the effect of reducing vibration and noise of the rail is achieved. During construction, the outer sleeve is pre-buried in the plate body, the spring assembly, the spring supporting plate, the height adjusting gasket and the locking gasket only need to be placed in from the opening in the upper end of the outer sleeve in sequence, the spring supporting plate and the height adjusting gasket are rotated to form a supporting structure during placement, then the supporting structure is fixed through the connecting piece, and therefore installation of the vibration isolator can be completed, construction is convenient, and the construction time is shorter. Similarly, during later maintenance, the vibration isolator can be conveniently disassembled and assembled, and the spring assembly can be conveniently replaced.
本发明提供一种规制式道床板、道床及其施工方法，由于该规制式道床板具有多个规制型隔振器，轨道板通过多个规制型隔振器的橡胶弹簧设置在基底上，即采用点支撑的方式，隔断轨道结构与基底结构之间的刚性联结，通过多个橡胶弹簧吸收列车运行时的冲击能量，从而实现轨道减振降噪的效果。在施工时，外套筒预埋在板体中，只需依次将弹簧组件、弹簧支撑板、调高垫片以及锁紧垫片从外套筒的上端开口放入，放入时转动弹簧支撑板和调高垫片形成支撑结构，再通过连接件固定即可完成隔振器的安装，因此，施工方便，施工时间更短。同样地，后期维护时，也可以方便地拆装该隔振器，更换弹簧组件。
