Roadbed structure at road filling and digging junction and construction method thereof
The invention discloses a road filling and digging junction roadbed structure and a construction method thereof, and relates to the technical field of road roadbed structures, the road filling and digging junction roadbed structure comprises a foundation road section, the foundation road section comprises a filling road section, a layering road section and a paving road section, a pavement layer is arranged above the filling road section, and a roadbed layer is arranged below the filling road section; a gravel layer is arranged at the bottom of the roadbed layer, double layers of geogrids are placed in the gravel layer, the upper layer of geogrid is located at the roadbed layer, and the lower layer of geogrid is laid below the upper layer of geogrid and has the same distance with the upper layer of geogrid located on the pavement layer; the longitudinal direction of the double-layer geogrid is perpendicular to the filling and digging boundary line of the roadbed. By arranging the filling compartments, the geogrids, the gravel blind ditches with a certain drainage function, the geocells and the like, the stability of the roadbed at the filling and digging junction of the road is higher, cracking of the concrete pavement is not prone to occurring, and therefore the economic burden needed for repairing the road and traffic obstruction are relieved.
本发明公开了一种公路填挖交界处路基结构及其施工方法，涉及公路路基结构技术领域，包括基础路段，所述基础路段包括填方路段、分层路段和铺筑路段，所述填方路段上方设有路面层，所述填方路段下方设有路床层，所述路床层底部设有碎石层、所述碎石层内放置有双层土工格栅，上层所述土工格栅位于路床层处，下层所述土工格栅铺设于上层所述土工格栅下方距离上层土工格栅位于路面层距离相同处，所述双层土工格栅纵向与路基填挖界限线垂直。本发明通过设置填方隔室、土工格栅以及具有一定排水功能的碎石盲沟以及土工格室等，使得公路填挖交界处的路基平稳性更强，不易出现混凝土路面的开裂，从而减轻了修复公路所需要的经济负担以及通行阻碍。
