Sponge city ecological roadbed structure based on original road and construction method thereof
The invention provides a sponge city ecological roadbed structure based on an original road comprises an original retaining wall and an original road surface, the outer wall of the original retaining wall is covered with a lattice frame, the lattice frame is fixedly connected with the original retaining wall through anchor rods, and anchoring sections of the anchor rods are anchored into bed rock; plant bags are arranged in the lattice frame, a plurality of first geogrids are arranged on the side, close to the original retaining wall, of the lower portion of the original road surface, a water-resisting layer and an unloading plate are sequentially arranged above the first geogrids, a flexible soil retaining structure is arranged above the unloading plate, the inner side end of the flexible soil retaining structure extends to the position above the original road surface, and a pervious concrete road surface is laid above the flexible soil retaining structure. Urban vertical space utilization rate is improved, self weight of an upper road structure is reduced, pressure of the original slurry stone retaining wall is reduced, and meanwhile construction efficiency is effectively improved.
本发明公开了一种基于原有道路的海绵城市生态路基构造，包括原始挡土墙与原始路面，在所述原始挡土墙的外壁上覆设有格构框架，该格构框架通过锚杆与原始挡土墙紧固连接，且所述锚杆的锚固段锚入基岩内，在所述格构框架内装设有植物袋，在所述原始路面的下方靠近原始挡土墙的一侧设置有若干道第一土工格栅，在所述第一土工格栅的上方依次设有隔水层与卸荷板，在所述卸荷板的上方设置柔性挡土结构，且该柔性挡土结构的内侧端延伸至所述原始路面的上方，在所述柔性挡土结构的上方铺设透水混凝土路面。提高了城市竖向空间利用率，减少了上部道路结构的自重，减轻了原浆砌石挡土墙的压力，同时有效地提高了施工效率。
