Hydraulic cementing filler vertical roadbed and road structure
The invention discloses a hydraulic cementing filler vertical roadbed and a road structure, and belongs to the technical field of roadbed construction, the hydraulic cementing filler vertical roadbed comprises protective walls on the left side and the right side and a foundation structure layer, the protective walls are vertically fixed on a soil foundation, and the bottom ends of the protective walls are located outside the soil foundation; the protective walls on the two sides define a filling area, and the outer side faces, back on to the filling area, of the protective walls extend upwards perpendicular to the upper surface of the soil matrix. The foundation structure layer is located in the filling area and fixedly connected with the protective walls on the two sides, and the foundation structure layer comprises a cementing filler part formed by naturally curing hydraulic cementing filler poured in the filling area. According to the vertical type roadbed with the hydraulic cementing filler, the characteristic that the shape is self-stable after the hydraulic cementing filler is cured is utilized, only the protective walls need to be arranged on the left side and the right side of the roadbed to protect the hydraulic cementing filler, and a traditional retaining wall does not need to be adopted to resist soil pressure; the construction difficulty and the construction cost of the roadbed are effectively reduced while the stability of the roadbed is ensured.
本发明公开了一种水硬性胶结填料直立式路基及道路结构，属于路基建设技术领域，该水硬性胶结填料直立式路基包括左右两侧的保护壁和基础结构层，保护壁直立固定在土基上且保护壁的底端位于土基外；两侧保护壁围成填筑区且保护壁背向填筑区的外侧面垂直于土基的上表面向上延伸；基础结构层位于填筑区内且与两侧保护壁固连，基础结构层包括由浇筑在填筑区中的水硬性胶结填料经自然固化形成的胶结填料部分。本发明的水硬性胶结填料直立式路基利用水硬性胶结填料固化后形状自稳的特性，仅需在路基左右两侧设置保护壁保护水硬性胶结填料而无需再采用传统挡墙抵挡土压力，在确保路基稳定性的同时有效降低路基的建设难度和建设成本。
