Roadbed structure in frozen soil area and construction method
The invention relates to the technical field of road engineering, in particular to a permafrost region roadbed structure and a construction method.The permafrost region roadbed structure comprises a lower roadbed, a first heat insulation layer and an upper roadbed which are sequentially arranged from bottom to top, the middle of the first heat insulation layer is low, the two sides of the first heat insulation layer are gradually raised, and a water collecting groove is formed in the upper end of the lower roadbed; an opening of the water collecting tank is vertically opposite to the lowest part of the first heat insulation layer; a drainage pipe for draining water in the water collecting tank is arranged in the lower roadbed; after being condensed at the lower end of the first heat insulation layer, water in the lower roadbed flows from higher positions on the two sides to a lower position in the middle along the lower end of the first heat insulation layer under the action of gravity and adsorption and flows into the water collection tank, and water in the water collection tank is discharged out of the water collection tank through a water drainage pipe; therefore, the permafrost region roadbed structure can discharge the condensed water at the lower end of the first heat insulation layer in time, soil softening of the lower roadbed is avoided, and then the safety of the roadbed is guaranteed.
本发明涉及道路工程技术领域，特别是涉及一种冻土区路基结构及施工方法，冻土区路基结构包括从下至上依次布置的下部路基、第一隔热层和上部路基，第一隔热层的中部低，且第一隔热层的两侧逐渐升高，下部路基的上端设有集水槽，集水槽的开口与第一隔热层最低处上下相对，下部路基中设有用于将集水槽中的水排出的排水管；下部路基中的水分在第一隔热层的下端凝结后，因重力和吸附作用沿着第一隔热层的下端从两侧较高的位置处向中部交较低的位置处流动，并流入集水槽中，集水槽中的水通过排水管排出集水槽；因此，本发明的冻土区路基结构能够将第一隔热层下端的凝结水及时排出，避免了下部路基的土质软化，进而保证了路基的安全。
