Recycled gravel rapid drainage roadbed structure
The invention relates to the technical field of highway subgrade structures and particularly relates to a recycled gravel rapid drainage roadbed structure. The drainage roadbed structure comprises a pavement layer, an upper recycled gravel layer, a geogrid layer, a gravel hardcore, a lower recycled gravel layer, a bottom gravel drainage layer and a side slope drainage plate, wherein the side slope drainage plate is arranged in an inclined mode and extends to the bottom gravel drainage layer from the road surface layer. Aiming at the base material used in the practical engineering of the secondary road, on one hand, through the arrangement, the downward seepage water of the pavement layer can be rapidly infiltrated downwards and guided, so the adverse effect of the seepage water on the roadbed and the pavement layer is effectively avoided, and phenomena of frost heaving, thaw collapse, frost boiling and the like of the pavement are prevented; on the other hand, due to the arrangement of the side slope drainage plates, the structural strength of the side slope can be remarkably enhanced, horizontal sliding resistance of the roadbed structure is increased, the roadbed structure can be more resistant to immersion and erosion of rainwater, and rapid drainage is further achieved.
本发明涉及公路路基结构技术领域，尤其涉及一种再生碎石快速排水路基结构,包括路面层、上路再生碎石层、土工格栅层、碎石垫层、下路再生碎石层、底部碎石排水层和边坡排水板；边坡排水板呈斜向设置，边坡排水板从路面层延伸至底部碎石排水层。本发明针对二级公路实际工程中所使用的基层材料，一方面通过上述设置，使得路面层向下的渗水能够快速下渗及导流，从而有效避免渗水对路基及路面层造成的不利影响，防止路面出现冻胀、融沉及翻浆等现象；另一方面，边坡排水板的设置不仅能够显著增强边坡的结构强度，增大了路基结构水平滑移的阻力，还能够使得路基结构更耐受雨水的浸入和侵蚀，进一步实现快速排水。
