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 secondary rain garden suitable for the construction of sponge cities, which includes a pit body, a covering layer, a planting layer, a sand layer, a gravel layer, and an overflow pipe. A soil loosening unit is set in the sand layer. After a period of use, the sand layer on the left side is loosened by the soil loosening unit to improve its purification effect; when loosening the sand layer, first wait for the sand layer to be dried, then The auxiliary drive mechanism sequentially drives the installation shafts in each loosening unit to rotate reciprocally; the rotation of the installation shafts drives the two rollers to rotate around the axis of the installation shafts, and at the same time, the rollers rotate around the installation shafts. Through the rotation of the rollers And rotate around the installation shaft to loosen and turn over the sand layer.

Description

[0001] Technical field [0002] The invention belongs to the technical field of rainwater gardens, in particular to a rainwater secondary use type rainwater garden suitable for sponge city construction. 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 coverin...
