Problems solved by technology

[0008] 3. Sand layer, due to the small particles of the sand layer, some pollutants with larger particles will be trapped in this layer during the infiltration of rainwater, which will block the sand layer and affect the infiltration speed
[0010] Through the above analysis, it can be seen that the particulate pollutants in the rainwater are easily accumulated in the gaps in the sand layer; and after several years of cumulative use, it will seriously affect the water absorption effect of the rain garden

Abstract

The invention belongs to the technical field of rain gardens, and in particular relates to a rain garden used in urban parks, which includes a pit body, a covering layer, a planting layer, a sand layer, a gravel layer, and an overflow pipe. In the present invention, by designing a drainage unit, the In stormy weather, the rainwater beyond the normal purification range of the rain garden is introduced into the sand layer on the right side of the partition through the drainage unit, and the part of the rainwater is purified to a certain extent through the sand layer on the right side. This part of the rainwater is relatively normal filtered rainwater Poor, but better than unpurified rainwater; therefore, compared with traditional rainwater gardens, the present invention has a part of rainwater that has been purified to a certain extent in addition to the normal purified rainwater, and the purification effect is relatively good.

Description

[0001] Technical field [0002] The invention belongs to the technical field of rain gardens, in particular to a rain garden used in city parks. Background technique [0003] The rain garden is a naturally formed or artificially excavated shallow concave green space, which is used to gather and absorb rainwater from the roof or the ground. Through the comprehensive action of plants and sand, the rainwater is filtered and purified, and it is gradually infiltrated into the soil to conserve groundwater. , or make it replenish urban water such as landscape water and toilet water. It is an ecologically sustainable rainwater control and rainwater utilization facility. [0004] But impurities in the early stages of rainwater can clog the permeable layer. [0005] The penetration layer is roughly divided into the following layers: [0006] 1. Covering layer. The covering layer refers to some impurities such as leaves covering the upper side. The covering layer has large pores and r...
