[0002] The embankment pavement refers to the pavement structure laid on the embankment surface during the embankment construction project. Its main function is to provide road access, increase the stability of the embankment, and prevent soil erosion. The selection and design of the embankment pavement usually need to consider many factors, including traffic load, soil characteristics, environmental conditions, engineering economy, etc.

The utility model arranges two different road surfaces to adapt to the actual conditions of different river sections, improve the overall performance, and enhance the versatility of the pedestrian walkway. However, the establishment of the walkway structure cannot guarantee the stability of the entire dike top. The dike top road surface may face various problems, the most important of which is foundation instability. If the foundation of the dike is unstable, for example, there is loose soil or collapse, it may cause the dike top road surface to sink, crack or become unstable. Therefore, the dike top walkway structure in the above application is prone to collapse after being used for a long time or being impacted by floods. Utility Model Content

The first reinforcement layer is fixed at the bottom wall of the opening, and one end of the first reinforcement column penetrates the first reinforcement layer and extends into the embankment. The connecting layer is fixed to the upper surface of the first reinforcement layer, and the second reinforcement layer is fixed to the side of the connecting layer away from the first reinforcement layer. One end of the second reinforcement column penetrates the second reinforcement layer, the connecting layer and the first reinforcement layer in sequence and extends into the embankment. The anti-seepage layer and the road surface layer are fixed to the second reinforcement layer in sequence from bottom to top.

[0007] Furthermore, the first reinforcement layer and the second reinforcement layer are a gravel layer and a crushed stone layer respectively, and the connection layer is a concrete layer.

At the same time, the anti-seepage layer and the cooperation between the drainage ditch are adopted to effectively prevent moisture from penetrating into the roadbed soil, further protect the underlying soil from moisture erosion, prevent soil loosening, loss and possible structural instability, thereby effectively ensuring the high strength of the ground.
