Embodiment

[0030] The diversion-type water-holding garden is located in the low-lying place in the middle of the low-lying green space 8, and the surrounding area of ​​the green space is 2m away from the outer wall of the diversion-type water-holding garden sump.

[0031] Annular sump 1, the width of the inner tank is 0.5m, and the height of the inner wall is 0.75m. The opening 2 on the outer wall of the tank is in the shape of an inverted equilateral trapezoid, the width of the bottom of the trapezoid is 0.25m, the angle between the hypotenuse and the vertical direction is 30°, and the height of the trapezoid is 0.375m. Pave pebbles with a diameter of about 5cm at the bottom of the sump.

[0032] The water inlet 3 of the water-holding area is as wide as the corridor, and its elevation is equal to the low elevation of the sump, and also equal to the elevation of the gravel barrier in the water-holding area. There is a right-angled triangle-shaped gravel belt at the water inlet in the wa...

Abstract

The invention discloses a baffled water holding garden system for treating rainwater collected in an urban residential area. The system comprises a baffled water holding region arranged in a lower greenbelt, and one side of the baffled water holding region is flush with one side of the lower greenbelt and provided with an overflowing water outlet channel; an annular water collecting trough encircles the left side, the lower side and the right side of the baffled water holding region; the outer wall of the annular water collecting trough close to the edge of the lower greenbelt is provided with a plurality of water inlet breaches, and the inner wall of the annular water collecting trough close to the lower left part of the baffled water holding region is provided with a water holding region water inlet; and a plant growing region which covers the baffled water holding region is arranged on the baffled water holding region. The system is provided with a guide wall and a broken stone blocking belt, the whole baffled water holding region is gridded, and the rainwater overflows to the next grid from each grid of the water holding region, so that the flowing time of the rainwater is prolonged, continuous flowing and seepage of the rainwater in the water holding region are promoted, and meanwhile, scouring of rainwater runoff to the vegetation belt is reduced.

Description

technical field [0001] The invention belongs to the technical fields of municipal engineering and environmental protection, and in particular relates to a baffle-type water-holding garden system for treating rainwater collected in urban residential quarters. Background technique [0002] With the acceleration of China's urbanization process, my country's natural environment has also been greatly damaged, natural watersheds have been greatly affected, and land use conditions have also been greatly changed. Concrete buildings, asphalt pavements, industrial and commercial areas, residential areas, parking lots and other large numbers of impermeable surfaces in cities have increased significantly, resulting in increased urban surface runoff, increased peak flow, and earlier peak flow. Changes in the natural hydrological cycle of cities caused by human activities have exacerbated the risk of urban waterlogging due to rainfall runoff, and the groundwater level has also decreased. ...
