Municipal road roadbed drainage structure and construction method thereof
The invention relates to a municipal road subgrade drainage structure which comprises a road body, the road body sequentially comprises a rammed earth layer, a gravel layer, a concrete base layer, a permeable layer, a leveling layer and a surface layer from bottom to top, a waterproof roll layer is laid between the concrete base layer and the gravel layer, a drainage pipe is embedded in the rammed earth layer, and the drainage pipe is connected with the permeable layer. The drainage pipe is communicated with a municipal sewage pipe network; a plurality of water retaining strips are fixedly arranged on the concrete base layer located on the slope road section, the length direction of each water retaining strip is horizontal, the water retaining strips are embedded in a permeable layer, drainage grooves are formed in the concrete base layer and located between every two adjacent water retaining strips, the drainage grooves are communicated with flow guide pipes, and the flow guide pipes are communicated with the drainage grooves. And the flow guide pipe is communicated with the drainage pipe. The method has the effect of reducing water and soil loss in the roadbed of the ramp road section.
本申请涉及一种市政道路路基排水结构，其包括道路本体，所述道路本体从下到上依次包括素土夯实层、砂石层、混凝土基层、透水层、找平层和面层，所述混凝土基层与砂石层之间铺设有防水卷材层，所述素土夯实层的内部埋设有排水管，所述排水管与市政污水管网连通；位于边坡路段的所述混凝土基层上固定设置有若干挡水条，各所述挡水条的长度方向水平，且所述挡水条嵌设在透水层内，所述混凝土基层上且位于相邻两所述挡水条之间均设置有排水槽，所述排水槽连通有导流管，所述导流管与排水管连通。本申请具有减少坡道路段路基内部水土流失的效果。
