Freeze-thaw cycle roadbed disposal method and structure
The invention discloses a freeze-thaw cycle roadbed treatment method, which belongs to the technical field of road construction, and comprises three parts, namely water blocking and water insulation, water drainage and deformation compensation, and the water blocking and water insulation are used for blocking surface water from entering a roadbed and isolating a connection channel between underground water outside the roadbed and the roadbed; the drainage is to collect underground water in the ground layer within the roadbed range and discharge the collected underground water out of the roadbed; according to deformation compensation, a cushion layer with the deformation characteristic opposite to that of the pavement base layer is used for counteracting the influence of deformation of the pavement base layer on the pavement. The invention further provides a freeze-thaw cycle roadbed structure, the water insulation assembly can block the connection between the pavement base layer and external formation water, water supply in the pavement base layer is reduced, and the increment problem is solved; the drainage assembly can reduce the content of underground water in the pavement base layer and solve the storage problem; the compensation cushion layer can correct the influence of the residual underground water, and plays a role in counteracting the deformation acting force of the pavement base layer. The invention has obvious effect and is suitable for wide popularization.
本发明公开了一种冻融循环路基处置方法，属于道路施工技术领域，包括三部分，分别是阻水隔水、排水和变形补偿，其中阻水隔水是阻断地表水进入路基及隔离路基以外地下水与路基的联系通道；排水是将路基范围内地层中的地下水汇集并排出路基；变形补偿是利用与路面基层相反的变形特性的垫层抵消路面基层的变形对路面的影响。本发明还提供一种冻融循环路基结构，隔水组件可以阻隔路面基层与外部地层水的联系，减少路面基层内水的补给，解决增量问题；排水组件可以降低路面基层内部地下水的含量，解决存量问题；补偿垫层可以对剩余地下水的影响进行纠正，起到抵消路面基层变形作用力的作用。本发明作用效果显著，适于广泛推广。
