Air isolation layer construction method, isolation overhead net and frozen soil roadbed construction method
The invention discloses an air isolation layer construction method, an isolation overhead net and a frozen soil roadbed construction method, and belongs to the technical field of roadbed construction. The method comprises the following steps: S1, a sandy gravel cushion layer is laid; and S2, an isolation overhead net is laid on the sandy gravel cushion layer, a hollow layer which can isolate the upper highway pavement from transferring heat downwards and is communicated with the outside on the shady slope side and the sunny slope side is formed, and ventilation holes which are in cold air convection with the shady slope are formed in the position, close to the shady slope, of the bottom of the hollow layer; the air isolation layer can isolate the highway pavement from the frozen earth surface, the hollow layer isolates heat transferred from the highway pavement on the upper portion to the frozen earth surface, convection wind can be formed on the shady slope and the sunny slope to bring the heat out of the hollow layer, and therefore the influence on the frozen earth surface is avoided, and meanwhile the ventilation holes and cold air on the shady slope can form downward convection cold flow. The temperature of the frozen earth surface is further adjusted to guarantee the original state of the frozen earth surface.
本发明公开了空气隔离层施工方法、隔离架空网及冻土路基施工方法，属于路基施工技术领域，包括以下步骤S1、铺设砂卵石垫层；S2、在砂卵石垫层上铺设隔离架空网，并形成可隔绝上部公路路面向下传递热量、且阴坡侧和阳坡侧均与外界相通的中空层，中空层的底部靠近阴坡的位置上设有与阴坡冷气对流的通风孔；空气隔离层能够将公路路面与冻土地表隔离，通过中空层隔绝上部公路路面向冻土地表传递的热量，阴坡阳坡能够形成对流风将热量带出中空层，从而避免对冻土地表的影响，同时通风孔与阴坡的冷空气能够形成向下对流的冷流，从而进一步调节冻土地表的温度保证冻土地表的原始状态。
