Frost heaving prevention roadbed and laying method thereof
The invention provides a frost heaving prevention roadbed and a laying method thereof. The frost heaving prevention roadbed comprises a roadbed body, a heating layer arranged on the top of the roadbed body and a control device electrically connected with the heating layer. The heating layer comprises at least two standard heating blocks; the standard heating block comprises a heating rod, a geogrid, a wire and a plug, the heating rod is arranged in a groove of the geogrid, and the heating rod is electrically connected through the wire. The anti-frost heaving roadbed can be used in newly built or reconstructed road engineering projects, and can also be mainly applied to transition sections such as bridges and culverts and frost heaving sections with poor geological conditions. The structure can quickly heat the subgrade in the area to form a layer of horizontal'hot film ', so that cold energy of air in winter is prevented from being quickly conducted downwards, and frost heaving of the subgrade is prevented.
本发明提供一种防冻胀路基及其铺设方法，该防冻胀路基包括路基体，设置于所述路基体顶部的加热层，以及与加热层电连接的控制装置；加热层包括至少2个标准加热块；所述标准加热块包括加热棒、土工格栅、导线以及插头，加热棒设置于所述土工格栅的凹槽内部，所述加热棒通过所述导线电连接。该防冻胀路基可在新建或者改建道路工程项目使用，也可重点应用在桥涵等过渡段和地质条件较差的冻胀段。该结构能快速加热区域路基温度，形成一层水平“热膜”，防止冬季空气的冷量快速向下传导，防止路基冻胀病害的产生。
