Novel nanometer hot rod high-speed rail roadbed for preventing frost heaving of roadbed in seasonal frozen soil area

The utility model discloses a novel nanometer hot rod high-speed rail roadbed for preventing frost heaving of a roadbed in a seasonal frozen soil area, the roadbed is wrapped by a layer of C25 fiber concrete, and fillers in the roadbed sequentially comprise a graded broken stone layer, a two-cloth one-film layer, a frost heaving prevention A/B group filler layer, a common A/B group filler layer and a plain soil compaction layer from top to bottom; wherein more than one nano hot rod mounting hole is formed in two sides of the roadbed, and a nano hot rod (3) is correspondingly arranged in each mounting hole. The utility model provides a new means for frost heaving prevention design and frost heaving treatment of the high-speed railway subgrade in the seasonal frozen soil area. The novel nanohot rod technology takes active prevention and control as a core thought, solar driving is used, heat is input through unpowered heating, the temperature of soil is increased, the freezing depth of aseasonal active layer of the roadbed is reduced, and the purposes of eliminating or reducing longitudinal irregularity and transverse deformation difference of the roadbed caused by frost heaving areachieved. 本实用新型公开了一种季节性冻土区防路基冻胀的新型纳米热棒高铁路基，所述路基由一层C25纤维混凝土包裹，所述路基内部填料由上到下依次为级配碎石层、两布一膜、防冻胀性A/B组填料层、普通A/B组填料层和素土夯实层；所述路基两侧开设有一个以上的纳米热棒安装孔，每个安装孔内对应设置有一个纳米热棒(3)。本实用新型为季节性冻土区高速铁路路基防冻胀设计及冻胀治理提供新手段。新型纳米热棒技术以"主动防治"为核心思想，使用太阳能驱动，无动力加热输入热量，升高土体温度，降低路基季节活动层冻深，达到消除或减小冻胀导致的路基纵向不平顺和横向变形差异的目的。
