Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0022] like Figure 1 As shown, a green landscape road includes a carriageway 1 and a sidewalk 2, and the sidewalks 2 are arranged on both sides of the carriageway 1. A green belt 3 is arranged in the middle of the carriageway 1 and on the side of the sidewalk 2 away from the carriageway 1. The height of the green belt 3 is lower than the carriageway 1 and the sidewalk 2 and is provided with an overflow pipe. The overflow pipe includes a first overflow pipe 35 and a second overflow pipe 36. The green belt 3 in the middle of the carriageway 1 is provided with a first overflow pipe 35, and the green belt 3 on the side of the sidewalk 2 is provided with a second overflow pipe 36. The green belt 3 has the function of alleviating water accumulation on the road and at the same time plays the role of dust prevention and noise reduction.

[0023] like Figure 2 As shown, a drainage mechanism is provided at the bottom of the carriageway 1, a water delivery mechanism is provided at the bottom of the sidewalk 2, an overflow pipe is connected to the drainage mechanism, and the drainage mechanism is connected to the water delivery mechanism. The overflow pipe allows the accumulated water on the road to flow into the water delivery mechanism and the drainage mechanism through the overflow pipe, so as to prevent flooding of the road in time.

[0024] The carriageway 1 includes an asphalt layer 17 and a cement layer 18, and the asphalt layer 17 is arranged on the cement layer 18. Below the cement layer 17, a gravel layer 12, a medium sand layer 14 and a base soil 34 are arranged in sequence. The gravel layer 12 has a stable structure, and the gaps between the gravel layers 12 can absorb a lot of water. The drainage mechanism is arranged in the gravel layer 12, and the position is stable and not easy to deform. The medium sand layer 14 can further filter and purify the water to prevent polluted water from infiltrating the base soil 34. A first waterproof geotextile 15 is arranged between the gravel layer 12 and the medium sand layer 14. The first waterproof geotextile 15 is used to prevent the materials between the gravel layer 12 and the medium sand layer 14 from being lost or mixed, so as to maintain the overall structure and function of the carriageway 1. The drainage mechanism includes a drainage pipe 13 and a first bottom pipe 16. The height of one end of the first overflow pipe 35 is located between the road surface of the carriageway 1 and the ground of the green belt 3, so as to collect the water flowing from the carriageway 1 to the green belt 3. The other end of the first overflow pipe 35 is connected to the drain pipe 13 through the first bottom pipe 16, and the excess water is discharged to the water body near the road or the municipal drainage network through the drain pipe 13. The road arch slope of the carriageway 1 is controlled at 1% to 1.5%, which does not affect traffic and can guide the accumulated water to both sides of the carriageway 1. There are curbstones 11 on both sides of the carriageway 1, and drainage holes are provided at the bottom of the curbstones 11. The curbstones 11 serve as the boundary between the carriageway 1 and the sidewalk 2, and at the same time guide the accumulated water out of the carriageway 1.

[0025] The sidewalk 2 is paved with sidewalk bricks, and the gaps between the sidewalk bricks are filled with gravel to ensure that the sidewalk 2 has a certain ability to seep water and prevent excessive water accumulation on the sidewalk 2. The one-way longitudinal slope of the sidewalk 2 is less than 2.5%. The side of the sidewalk 2 close to the carriageway 1 is higher than the side close to the green belt 3. It is convenient to guide the accumulated water to the green belt 3 to prevent excessive water accumulation on the sidewalk 2. The sidewalk 2 is composed of a layer of plain soil 22, a gravel layer 12, a medium sand layer 14 and a base soil 34 in order from the surface to the underground. A second waterproof geotextile 24 is provided between the plain soil 22 layer and the gravel layer 12, and the second waterproof geotextile 24 is used to maintain the stability of the sidewalk 2 structure. The gravel layer 12 is provided with a water conveying mechanism, which includes a second bottom pipe 33 and a plurality of permeable blind pipes 25. The height of one end of the second overflow pipe 36 is located between the pavement of the sidewalk 2 and the ground of the green belt 3, and the other end is connected to the permeable blind pipe 25 through the second bottom pipe 33, and the permeable blind pipe 25 is connected to the drainage mechanism. The excess water in the green belt 3 is led to the drainage mechanism through the water delivery mechanism. A plurality of tree pits 21 are provided on the sidewalk 2, and the tree pits 21 are evenly distributed along the length direction of the sidewalk 2, and trees 23 are planted in the tree pits 21. The tree pits 21 have a certain water storage function and can accommodate a part of the water on the road. The trees 23 can provide shade for the sidewalk 2 and absorb dust and noise on both sides of the roadway 1.

[0026] The green belt 3 is composed of a planting soil layer 31 and a base soil 34 in order from the surface to the ground. The planting soil layer 31 is planted with a variety of local waterlogging-resistant shrubs 32. The various shrubs 32 can increase the species diversity of the green belt 3 and enhance the ecological value and ornamental value of the green belt 3. The use of local waterlogging-resistant shrubs 32 varieties can increase the survival probability of the green belt 3.

[0027] The working principle of the specific implementation of the utility model is as follows: the accumulated water on the roadway 1 flows to the drainage mechanism and the water delivery mechanism through the first overflow pipe 35 and the second overflow pipe 36 respectively, and is finally discharged. The multi-layer structure at the bottom of the roadway 1 and the sidewalk 2 can store a part of the accumulated water, and the green belt 3 can absorb a certain amount of accumulated water and provide ecological value.
