Steel spring vibration isolation system and construction method thereof
The invention provides a steel spring vibration isolation system which comprises a plurality of roadbed slabs which are sequentially connected end to end, slab bodies of the roadbed slabs are loaded on a base through a plurality of steel spring vibration isolators, rigid connection between a track structure and a base structure is isolated in a point supporting mode, and impact energy generated when a train runs is absorbed through a plurality of steel springs. And the vibration and noise reduction effect of the track is achieved. Furthermore, each steel spring vibration isolator comprises a vertically-through outer sleeve pre-buried in the plate body, a height adjusting gasket, a locking gasket and an elastic element, each elastic element comprises a spring shell, a first steel spring and a second steel spring, the first steel springs and the second steel springs are arranged in the spring shells, and when track construction is conducted, the elastic elements only need to be installed as a whole, so that the construction efficiency is improved. During installation, the elastic element, the height adjusting gasket and the locking gasket are sequentially placed from the upper end opening of the outer sleeve, the elastic element and the height adjusting gasket are rotated to form a supporting structure with the outer sleeve during placing, then the supporting structure and the outer sleeve are fixed through the connecting piece, and therefore construction is convenient, and the construction period is short.
本发明提供一种钢弹簧隔振系统，包括多块依次首尾相接的道床板，道床板的板体通过多个钢弹簧隔振器载置在基底上，采用点支撑的方式隔振轨道结构与基底结构之间的刚性联结，通过多个钢弹簧吸收列车运行时的冲击能量，实现轨道减振降噪的效果。进一步，钢弹簧隔振器包括预埋在板体中的竖直贯通的外套筒、调高垫片、锁紧垫片以及弹性元件，弹性元件包括弹簧壳体以及设置在弹簧壳体内的第一钢弹簧和第二钢弹簧，在进行轨道施工时，弹性元件仅需作为一个整体进行安装，依次将弹性元件、调高垫片和锁紧垫片从外套筒的上端开口放入，放入时转动弹性元件、调高垫片使其与外套筒形成支撑结构，再通过连接件固定即可完成安装，因此，施工方便、工期短。
