Rainwater retention system
The invention relates to the technical field of urban rainwater management, in particular to a rainwater retention system. The rainwater retention system comprises a covering layer, a soil medium layer and a drainage layer which are arranged from top to bottom. The covering layer comprises a plurality of covering layer recycled aggregate particles, the soil medium layer comprises a soil medium recycled aggregate assembly and a landscaping waste compost product assembly, and the drainage layer comprises a plurality of drainage recycled aggregate particles. According to the rainwater retention system, arrangement of a transition layer is avoided, the drainage pipe does not need to be wrapped by geotechnical cloth, the overall structure is simple, it can be guaranteed that the emptying time of the system at the initial operation stage reaches 1-3 h, soil particle loss can be prevented, the blocking risk is low, the failure risk is small, and plant growth can be guaranteed.
本发明提供了一种本发明涉及城市雨水管理技术领域，尤其是涉及一种雨水滞留系统。所述雨水滞留系统，包括：由上而下设置的覆盖层、土壤介质层和排水层；所述覆盖层包括多个覆盖层再生骨料颗粒，所述土壤介质层包括土壤介质再生骨料组合件和园林绿化废弃物堆肥产物组合件，所述排水层包括多个排水再生骨料颗粒。本发明提供的雨水滞留系统避免设置过渡层，无需用土工布包裹排水管，整体结构简单，能保证系统运行初期排空时间达到1h～3h，可防止土壤颗粒流失，堵塞风险低，失效风险小，并能保证植物生长。
