Seasonally frozen soil area roadbed anti-freezing structure and construction method thereof
The invention relates to a seasonally frozen soil area roadbed anti-freezing structure and a construction method thereof, and belongs to the technical field of seasonally frozen soil area roadbed anti-freezing. The overall longitudinal section of the roadbed structure is trapezoidal, the roadbed structure sequentially comprises a roadbed, a gravel layer, a packing layer, a cement stabilized macadam layer, a conductive base layer and a pavement layer from bottom to top, and the roadbed structure further comprises a roadbed anti-freezing structure heating control system and a power supply system; and the gravel layer can prevent underground water in cold seasons from migrating to the upper part of the roadbed structure. Some industrial waste can be mixed into the conductive base layer to beturned into wealth, the electric heating effect is achieved, freezing of the roadbed structure is prevented, freezing of the roadbed structure side slope can be prevented through the hard heat preservation plate and the gravel slope protection layer of the side slope, water in the roadbed can be drained through an one-way drainage pipe, and freezing of the roadbed structure is prevented. Accordingto the seasonally frozen soil area roadbed anti-freezing structure and the construction method thereof, active defense, passive heat preservation and waterproof and drainage principles are comprehensively adopted, frost heaving of the roadbed in the seasonally frozen soil area can be effectively prevented, and the freeze-thaw resistance stability of the roadbed structure is improved.
本发明涉及一种季节冻土区路基防冻结构及其施工方法，属于季节冻土区路基防冻技术领域。所述路基结构整体纵截面为梯形，路基结构从下往上依次为路基、砂砾层、填料层、水泥稳定碎石层、导电基层和路面层，还包括路基防冻结构加热控制系统和供电系统；砂砾层可以阻止冷季地下水向路基结构上部的迁移通道。导电基层可以将有些工业废料掺入变废为宝，具有电热效应，防止路基结构的冻结，边坡的硬质保温板和砂砾护坡层可以防止路基结构边坡的冻结，单向排水管可以将路基内部的水分排出，防止路基结构冻结。本发明综合采用了主动防御、被动保温以及防排水原理，可以有效地防止季节冻土区路基的冻胀，提高路基结构的抗冻融稳定性。
