Embodiment 1
[0024] Embodiment 1: The hilly continuous type landscape belt stagnation storage, filtration and drainage system adopted in this embodiment (attached figure 1 ) can be used for long strips of landscape belts in areas such as urban roads, expressways, expressways, river banks, and lakesides. The construction method is as follows: Excavate the original soil 3 at the position of the landscape belt to 1500mm-2000mm below the road surface. Base soil layer 2, that is, backfill the original soil with fine clay 12 with a particle size of less than 0.001 mm and a thickness of 500 mm, coarse powder with a particle size of 0.05-0.01 mm and a thickness of 500 mm 13, and a particle size of 0.1-0.25 mm in thickness 500mm of fine sand 14, hilly planting soil 15 with a thickness of 300mm, and the vegetation layer 1 is arranged on the planting soil 15. Considering terrain undulations, landscape requirements, water distribution, etc., select medium and small trees 16, various shrubs 17, and la...
Embodiment 2
[0028] Embodiment 2: The hilly continuous type landscape belt stagnation, storage, filtration and drainage system adopted in this embodiment (attached figure 2 ) can be used for landscape belts in wide areas such as living areas, gardens, and squares. The construction method is as follows: Excavate the original soil 3 at the position of the landscape belt to 1000mm-1500mm below the road surface. Base soil layer 2, that is, backfill the original soil with fine clay 12 with a particle size of less than 0.001 mm and a thickness of 500 mm, coarse powder with a particle size of 0.05-0.01 mm and a thickness of 300 mm 13, and a particle size of 0.1-0.25 mm. 100mm fine sand 14, hilly planting soil 15 with a thickness of 300mm, and a vegetation layer 1 is arranged on the planting soil 15. Taking into account the undulations of the terrain, landscape requirements, and water distribution, various trees 16, shrubs 17, and lawn grasses 16 are optimally arranged in the planting soil layer, ...
