Sinking type greenbelt
The invention discloses a sinking type greenbelt. The sinking type greenbelt comprises a planting layer located on a surface layer of the sinking type greenbelt, and is characterized in that a first-stage detention tank is arranged in the sinking type greenbelt; a water retention sand layer is located between the planting layer and the first-stage detention tank; a second-stage detention tank is arranged in the first-stage detention tank; the interior of the second-stage detention tank is divided into three areas; an central area is a settling area, and the two sides are osmotic filtration areas; the settling area and the osmotic filtration areas are separated by a clapboard; the top end of the clapboard is an overflow weir; a water inlet of the second-stage detention tank is formed abovethe central settling area; and water outlets are formed in the bottoms of the osmotic filtration areas. The sinking type greenbelt overcomes the defects of a traditional sinking type greenbelt, has the advantages of being good in rainwater regulation and storage effect, high in purification efficiency and capable of avoiding pollution to underground water, and meanwhile is simple in structural design, low in operation cost and easy to apply and popularize.
本发明公开一种下沉式绿地，包括种植层，所述种植层位于下沉式绿地表层，其特征在于：下沉式绿地内设有一级调蓄池，所述保水砂层位于种植层与一级调蓄池中间，一级调蓄池内设有二级调蓄池，所述二级调蓄池内部分为三个区域，中央区域为沉淀区，两侧为渗透过滤区，沉淀区和渗透过滤区之间利用隔板隔开，隔墙顶端为溢流堰；中央沉淀区的上方设有所述二级调蓄池的进水口，渗透过滤区底部为出水口。本发明克服了传统下沉式绿地的不足，具有雨水调蓄效果好、净化效率高、避免污染地下水的优点，同时结构设计简单、运行成本低、易于推广应用。
