Example Embodiment

[0039] Example 1:

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

[0041] The structure of the functional rain garden 21 includes pretreatment facilities 23, aquifer 24, seepage facilities 25, and overflow facilities.

[0042] Among them, the pretreatment facility 23 includes a circular slope and gravel covering the circular slope. The circular slope is located at the junction of the functional rainwater garden 21 and the green space 22. The slope of the circular slope is 35°, the width is 43cm,...

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...
