Problems solved by technology

At present, most of the sections of the landscape belt are horizontal structures that are higher than the road surface. The advantage is that the precipitation and runoff of the landscape belt can be eliminated in time, but the water holding effect of the landscape belt is poor, which is easy to cause soil erosion, and is not conducive to the discharge of rainwater from urban roads.
In 2014, the sunken green space was proposed in the construction of the sponge city. Although the seepage process of the landscape belt is prolonged, it is easy to cause water accumulation in the landscape belt, and the road landscape belt may also affect the safety of the roadbed.

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, ...

Abstract

The present invention discloses a retention, storage, filtration, discharge and guide system of a hilly extending landscape zone. The system comprises a vegetation layer, a foundation soil layer, an original soil layer, and a discharge channel vertically disposed through the foundation soil layer to an excavation face, which are arranged in sequence from top to bottom. The excavation face is located at an upper interface of original soil. In the present invention, rainwater is held by the vegetation layer and permeates the layer, thereby reducing a rainwater source of urban runoff. The foundation soil layer provides soil for plant growth. Rainwater on roads is held and permeates, stored, and filtered, thereby decreasing a pollution load of urban runoff. The discharge channel not only can quickly discharge gathered water in the landscape zone, but also can release water stored in the foundation soil layer for plants in the landscape zone during a drought, thereby effectively solving the problem of difficult landscape conservation. The system disclosed by the present invention integrates retention, storage, filtration, discharge and guide functions with a landscape function. The disadvantages of recessed green land are improved. The area of landscape region is increased, the rainwater source of urban runoff is reduced, and the pollution load is decreased. Furthermore, the conservation problem of partially requiring water in the landscape zone is solved. The system is beautiful and practical with a harmonious relationship between human and water, and the construction is simple.

Description

technical field [0001] The invention belongs to the fields of rainwater stagnation, storage, filtration and removal in urban landscape belts, and relates to a landscape belt stagnation, storage, filtration and drainage system. Background technique [0002] The landscape belt has many functions such as greening and environmental protection, beautifying the urban environment, etc. The common types mainly include urban road landscape belt, riverside landscape belt, green land landscape belt, garden landscape belt, etc. At present, most of the sections of the landscape belt are horizontal structures that are higher than the road surface. The advantage is that the precipitation and runoff of the landscape belt can be eliminated in time. However, the water holding effect of the landscape belt is poor, which is easy to cause soil erosion, and is not conducive to the discharge of rainwater from urban roads. In 2014, the sunken green space was proposed in the construction of the spon...
