Embodiment 1

[0024] Embodiment 1: a kind of low potential green space system (referring to attached figure 1 , attached figure 2 ), including the low-level green space 1 and drainage channel 2 whose edge is lower than the road surface 17, and the edge of the low-level green space is equipped with a hidden overflow channel 3, the overflow channel is placed above the drainage channel, the overflow channel is connected with the drainage channel, and the overflow channel An overflow plate 4 is arranged on the edge of the flow channel, and the upper end of the overflow plate is higher than the low-level green space; vegetation 5 is planted on the low-level green space. The low-lying green space includes a planting soil layer 6, a crushed stone layer 7, and a compacted plain soil layer 8 from top to bottom, and a permeable geotextile 9 is laid between the planting soil layer and the crushed stone layer.

Embodiment 2

[0029] Embodiment 2: a kind of low-potential green space system (referring to attached image 3), its structure is similar to that of Embodiment 1, the main difference is that in this embodiment the upper end of the overflow channel is hinged with a decorative plate 22, the decorative plate covers the upper opening of the overflow channel, and there is an overflow gap between the decorative plate and the overflow plate 23. An arc-shaped flushing plate 24 is hinged in the overflow channel. The flushing plate is connected to the ejector rod 25. The ejector rod is arranged obliquely, and the upper end of the ejector rod abuts against the lower surface of the decorative plate; The deflector 26 provided, the lower end of the deflector is placed above the flushing plate. Decorative vegetation 27 is arranged on the surface of the decorative board. The lower surface of the decorative plate is provided with a limiting protrusion 28, and the upper end of the push rod abuts against the ...

Abstract

The invention discloses a low greenbelt system, and aims to overcome the defects that a sunken greenbelt overflow well occupies a large area, has great influence on a greenbelt landscape effect and is poor in overflowing capacity. The low greenbelt system comprises a low greenbelt with the edge lower than the road surface and a drainage channel, wherein the edge of the low greenbelt is provided with a hidden overflow channel, the overflow channel is arranged above the drainage channel, the overflow channel communicates with the drainage channel, the edge of the overflow channel is provided with an overflow plate, the upper end of the overflow plate is higher than the low greenbelt, and vegetation is planted on the low greenbelt. According to the low greenbelt system, an overflow port of the low greenbelt system is designed in a hidden manner, so that the occupied area is greatly reduced, the influence on the landscape effect of the greenbelt is reduced, and the overflow capacity is good.

Description

technical field [0001] The invention relates to a rainwater management technology for urban green space, more specifically, it relates to a low-lying green space system. Background technique [0002] At present, China has entered a stage of rapid urbanization. With the transformation of old cities and the construction of new cities, the city's water security, water environment, water resources, and water ecological conditions are facing severe challenges. The degree of urban development continues to increase, the impermeable area gradually increases, and the surface runoff increases rapidly, resulting in a sharp increase in the pressure on the traditional "drainage-based" pipe network system, frequent occurrence of waterlogging, and threats to urban water security. Practice has proved that simple engineering measures are not an effective way to solve problems such as "the city looks at the sea", "runoff pollution", "heat island effect", and "hydrological cycle damage", but ...
