Embodiment 1

[0040] A functional rainwater garden 21 is set up in the green space between the model houses in the southern part of the landscape demonstration area of ​​the villa area in Xiangcheng District, Suzhou Greenland, to collect the runoff generated in the green space 22 . Such as image 3 and 4 As shown, the functional rain garden 21 has an area of ​​12m 2 , the shape is kidney-shaped, the length of the bottom is 4.8m, the width is 2.5m, and the thickness of the structure is 105cm, image 3 and Figure 4 The arrow 40 in gives the flow direction of the rainfall runoff.

[0041] The structure of the functional rain garden 21 includes a pretreatment facility 23, an aquifer 24, an infiltration facility 25 and an overflow facility.

[0042] Wherein, the pretreatment facility 23 includes a circular slope and gravel covered on the circular slope. The circular slope is located at the junction of the functional rain garden 21 and the green space 22. The slope of the circular slope is 3...

Embodiment 2

[0049] A functional rainwater garden 41 is set up in the green space among high-rise residential buildings in Shenghui Community, Baoshan Green Sea Area, Shanghai, to collect the runoff generated in the green space 42 . Such as Figure 5 and 6 As shown, the functional rain garden 41 has an area of ​​39m 2 , the shape is kidney-shaped, the bottom length is 8.5m, the width is 4.6m, and the structure thickness is 160cm, Figure 5 and Figure 6 The arrow 60 in gives the flow direction of the rainfall runoff.

[0050] The structure of the functional rain garden 41 includes a pretreatment facility 43, an aquifer 44, an infiltration facility 45 and an overflow facility.

Abstract

The invention discloses a functional rainwater garden suitable for the interior of an urban community grassy area in Shanghai. The functional rainwater garden suitable for the interior of urban community grassy area in Shanghai comprises pretreatment facilities, a water storage layer, water seepage facilities and an overflow facilities, wherein the pretreatment facilities comprise a ring-shaped side slope and gravels; the ring-shaped side slope is positioned on the periphery of the functional rainwater garden; the gravels are covered on the ring-shaped side slope; the water storage layer is a space formed by the ring-shaped side slope and the bottom of the functional rainwater garden in a horizontally encircling manner; the water seepage facilities are positioned at the bottom of the functional rainwater garden; the overflow facilities comprise an overflow pipe penetrating through the thickness direction of the water storage layer and an overflow drain pipe positioned at the bottom of the functional rainwater garden. The functional rainwater garden suitable for the interior of urban community grassy area in Shanghai provided by the invention can decrease the rainfall runoff peak value, purify water quality, supplement groundwater, reduce pressure on municipal water draining, improve microclimate and lift the livable degree of Shanghai.

Description

technical field [0001] The invention relates to a functional rainwater garden, in particular to a functional rainwater garden suitable for the interior of Shanghai urban community green spaces, and belongs to the technical field of rainwater management. Background technique [0002] In recent years, the impact of the "rain island effect" and "turbid island effect" in Shanghai has been intensified, and the precipitation in the city has been significantly greater than that in the surrounding suburbs. According to statistics, the rainfall in the flood season from June to September in the Shanghai area in the past 30 years has been in Xujiahui, an urban area. It is nearly 1.5% more than Fengxian in the suburbs. In addition, with the acceleration of urbanization, the area of ​​river courses in cities has been greatly reduced, and the underlying surfaces are mostly asphalt roads and cement roads, etc., which affect water infiltration. At present, my country's drainage standards a...
