Permafrost region side slope ventilation pipe block stone cooling roadbed
The invention relates to a permafrost region side slope ventilation pipe block stone cooling roadbed. The cooling roadbed comprises block stone layers laid on the two slope surfaces of an embankment, and geotechnical cloth, a heat preservation plate and a clay layer which are sequentially laid on the block stone layers. And a plurality of ventilation pipes are uniformly distributed in the block stone layer. The slope heat insulation structure not only has a remarkable slope heat insulation effect, but also has the ventilation and cooling effects of the block stone layer and the ventilation pipe; the convection intensity of forced convection flowing through the pores of the block stone layer in a cold season is obviously increased compared with that of a common block stone slope protection roadbed, so that more heat in the roadbed is taken away more quickly, permafrost at the lower part is cooled, and the long-term thermal stability of the roadbed is realized.
本发明涉及一种多年冻土区边坡通风管块石冷却路基，该冷却路基包括铺设于路堤两坡面上的块石层以及依次铺设在所述块石层上的土工布、保温板、粘土层；所述块石层内均布有数根通风管。本发明不仅具备显著的边坡隔热效果，同时具备块石层、通风管的通风降温效果；冷季流经块石层孔隙的强迫对流的对流强度较之普通块石护坡路基要明显增大，从而更快更多地带走路基内的热量，进而冷却下部多年冻土，实现路基的长期热稳定性。
