[0003] In response to the above needs, highway design and construction units are trying to improve the landscape effect of highways. They green the slopes of highways, add landscapes on roadside platforms, design roadside trees on both sides of highways, plant flowers and grass, etc. However, due to the steep terrain inside some highways, in order to reduce excavation during construction, the space inside the highway is limited, making it difficult to plant plants.

[0004] Specifically, there is a ditch with an upward opening on the inner side of the highway, and the side of the ditch away from the road surface is a slope. The inner ditch of the highway refers to a longitudinal artificial ditch set on the outside of the shoulder of the excavated roadbed, which is mainly used to collect and drain precipitation from the road surface, shoulder and slope to ensure the stability of the roadbed and the smoothness of the drainage system. The ditch is an important part of the surface drainage facilities of the highway and plays an important role in maintaining the stability of the roadbed. The space of the inner ditch of the existing highway is limited, making it difficult to plant plants, and no green landscape design has been carried out, and the ditch is simple in form.
