Embodiment 1

[0029] A rain garden system for community rainwater diversion, peak shaving and ecological purification is installed in the high-rise residential area of ​​Baoshan Yanghang Residential Community in Shanghai to collect runoff generated by community roof rainfall.

[0030] The community is a 12-story high-rise residence with a plot ratio of 4, a green area of ​​40%, and a roof area of ​​33%. The area enclosed by the outer circle of the annular slope of the pretreatment facility 7 is 50m 2 , the shape is kidney-shaped, the bottom length is 10.0m, the width is 6.0m, and the structure thickness is 200cm. The pretreatment facilities include that the slope of the circular slope is 33° and the width is 70cm; the thickness of the gravel covered on the slope is 6cm, and the particle size is 4cm; the bottom of the aquifer 12 is about 20cm lower than the green land 9; The thickness of the fine stone is 5cm, and the particle diameter is 1cm; The vegetation of planting layer 14 is the vine...

Embodiment 2

[0033] A rain garden system for community rainwater diversion, peak shaving and ecological purification was installed in the residential green space of Shenghui Community in Baoshan Greenland Sea Area, Shanghai, to collect the runoff generated by community roof rainfall.

[0034] The community is a 6-storey multi-storey residence with a plot ratio of 1.5, a green area of ​​40% and a roof area of ​​25%. The area enclosed by the outer circle of the annular slope of the pretreatment facility 7 is 20m 2 , the shape is kidney-shaped, the bottom length is 8.0m, the width is 4.0m, and the structure thickness is 80cm. The slope of the annular slope of the pretreatment facility 7 is 35°, and the width is 40cm; the thickness of the gravel covered on the slope is 4cm, and the particle size is 4cm; the bottom of the aquifer 12 is about 15cm lower than the green sag; The thickness of the stone is 5cm, and the particle size is 1cm; the planting layer 14 vegetation is dwarf Ophiopogon japon...

Abstract

The invention discloses a rainwater garden system for community rainwater diversion, peak shaving and ecological purification, comprising community roof rainwater flow-through facilities, inverted U-shaped buffer diversion pipes, green space rainwater garden facilities and rainwater wells; the community roof rainwater The flow-through facility is connected with the green space rain garden facility in two ways, one way is directly connected with the green space rain garden facility, and the other way is through the inverted U-shaped buffer diversion pipe and the green space rain garden facility. The facility is connected; the green space rain garden facility is also connected with the rainwater well. The inverted U-shaped buffer diversion pipe and the green space rain garden facilities from the ground down include the water storage layer, covering layer, planting layer, transition layer, filling layer, drainage layer and supporting pipelines so that the rain garden system has the initial stage of treatment. The role of diversion, peak shaving and purification regulation of rainwater runoff.

Description

technical field [0001] The invention belongs to the field of rain garden systems for treating rainfall in urban green areas, and specifically relates to the construction of a rain garden system suitable for rainwater diversion, peak shaving and ecological purification on urban community roofs. Background technique [0002] Since the 1970s, the concept of international urban rainwater control has changed. Rainwater storage, slow discharge, and utilization have become important contents of rainwater management. From the perspective of water quantity and water quality management, implement "ecological drainage" through various engineering and non-engineering measures to promote precipitation into the natural water cycle process as much as possible, thereby reducing the amount of rainwater entering the urban drainage system and promoting rainwater drainage. The utilization of resources can alleviate urban flood disasters, reduce urban sewage treatment loads and construction cost...
