Freeze proof bloated ballastless track roadbed structure of rich irrigated land base

The utility model provides a freeze proof bloated ballastless track roadbed structure of rich irrigated land base to effectively improve the freeze proof bloated deformation effect of low embankment of ballastless track high -speed railway and cutting, be convenient for in addition construct. It includes: the reinforced concrete drilled pile, way along the line longitudinal separation sets in a row, the loading board sets up at reinforced concrete drilled pile top and concreties with it, the screed -coat sets up on the base of the rich irrigated land, the buffering supporting layer sets up between loading board and screed -coat, the track board sets up at the loading board top and concreties with it. 种富水地基抗冻胀无砟轨道路基结构，以有效提高无砟轨道高速铁路低路堤及路堑的抗冻胀变形效果，而且便于施工。它包括：钢筋混凝土钻孔桩，沿线路纵向间隔成排设置；承载板，设置在钢筋混凝土钻孔桩顶部并与之固结；找平层，设置在富水地基上；缓冲支撑层，设置在承载板与找平层之间；轨道板，设置在承载板顶部并与之固结。
