The invention discloses a
solar heat collection device facing seasonal
frost area roadbed construction, and an implementation method, and relate to the technical field of frozen soil roadbed
disease control. The
solar heat collection device facing seasonal
frost area roadbed construction comprises an overground heat collecting unit and a roadbed heat supplying unit, wherein the overground heat collecting unit comprises a heat absorption
pipe; an outer sleeve
pipe sleeves on the outer part of the heat absorption
pipe; a heat insulation cavity is formed between the heat absorption pipe and the outer sleeve pipe; two ends of the heat absorption pipe and the outer sleeve pipe are connected through sealing sections; the roadbed heat supplying unit comprises a heat supplying pipe; the heat absorption pipe communicates with the heat supplying pipe; and
heat transfer fluids are filled in the heat absorption pipe and the heat supplying pipe. According to the
solar heat collection device facingseasonal
frost area roadbed construction, and the implementation method provided by the invention, seasonal heat collection-output balance of a frozen soil roadbed is reasonably and effectively controlled, and an anti-freezing expansion effect is more effective; the energy is saved, and the cost and the manual labor intensity are reduced; the solar heat collection device is high in heat collectionefficiency, good in freezing resistance, leakproof, compact in structure, small in size, small in occupied area, flexible in arrangement ways, and capable of being dispersedly arranged; and comparedwith a boundary protection effect of an existing heat insulation material, all-directional close-range
heat supply of a freezing expansion stratum can be realized.
