Soft soil roadbed structure and construction method thereof
The invention discloses a soft soil roadbed structure and a construction method thereof. Belongs to the technical field of roadbed construction, the soft soil roadbed structure comprises a first sheet-pile wall, a second sheet-pile wall, a reinforcing layer, a backfill layer, a pavement layer and a drainage maintenance system, the backfill layer comprises second gravel backfill soil, a water retaining piece and clay backfill soil which are sequentially arranged from top to bottom, and the backfill layer uses the clay backfill soil as a part of filling materials. The use amount of the first gravel backfill soil in the backfill layer can be reduced, so that the engineering cost is saved, the water retaining piece can prevent water from falling into the clay backfill soil, the clay backfill soil is kept dry, the structural strength of the backfill layer is guaranteed, and the stability of the soft soil roadbed structure is guaranteed.
本发明公开了一种软土路基结构及其施工方法。属于路基施工技术领域，该软土路基结构包括第一板桩墙、第二板桩墙、加固层、回填层、路面层和排水维护系统，回填层包括由上至下依次排布的第二砂石回填土、挡水件和黏土回填土，回填层利用黏土回填土作为一部分填充材料，可减少回填层中第一砂石回填土的用量，从而有利于节省工程成本，挡水件可阻挡水落入黏土回填土中，有利于保持黏土回填土干燥，从而保证回填层的结构强度，保证软土路基结构的稳定性。
