Municipal soft soil roadbed and construction method
The invention discloses a municipal soft soil roadbed and a construction method, and relates to the technical field of municipal roads; the municipal soft soil roadbed comprises a soft soil base layer, the upper surface of the soft soil base layer is provided with a base layer groove, the inner bottom wall of the base layer groove is provided with a lime layer, the upper surface of the lime layer is provided with a bedding layer, and the upper surface of the bedding layer is provided with a concrete reinforcing layer; transverse reinforcing ribs are arranged in the concrete reinforcing layer, and longitudinal reinforcing ribs are arranged in the concrete reinforcing layer. According to the municipal soft soil roadbed and the construction method, the bedding layer is subjected to three-time laying construction and layered leveling and compaction, the compactness is improved, and then the stability of the roadbed is improved; in the cushion layer, the transverse reinforcing ribs and the longitudinal reinforcing ribs are arranged between the first-time laying and the second-time laying and between the second-time laying and the third-time laying respectively, the supporting force of the soft soil base layer is enhanced, the bearing force of the soft soil base layer is further improved, and the situation that a road structural layer is damaged due to landslide and instability of a pavement embankment is avoided.
本发明公开了一种基于市政软土路基及施工方法，涉及市政道路技术领域，包括软土基层，所述软土基层的上表面设有基层槽，所述基层槽的内底壁设有石灰层，所述石灰层的上表面设有铺垫层，所述铺垫层的上表面设有混凝土加固层，所述混凝土加固层的内部设有横向加强筋，所述混凝土加固层的内部设有纵向加强筋。该基于市政软土路基及施工方法，通过铺垫层采用三次铺设施工，分层整平压实，提高密实度，进而提高路基的稳定性；本发明的垫层中，第一次与第二次铺设之间和第二次与第三次铺设之间分别设有横向加强筋和纵向加强筋，增强软土基层的支撑力，进一步提高软土基层的承载力，避免了路面路堤塌方，失稳，造成道路结构层的破坏。
