The invention discloses a construction method of a rainwater garden in sponge city transformation. The construction method is characterized by comprising the following steps of S1, performing construction preparation; S2, treating a base layer; S3, building and joining water collecting wells; S4, paving an HDPE impermeable layer; S5, paving a gravel cushion layer, a gravel cushion layer and a water-permeable blind pipe; S6, constructing a non-horizontal filtering water storage layer; S7, backfilling the planting soil; S8, performing construction of drainage curbs and a buffer area; and S9, performing green land planting. The construction method of the rainwater garden in sponge city reconstruction has the advantage of relatively low construction management cost, the construction of hard pavement and municipal rainwater pipelines is greatly reduced by the construction of the rainwater garden, urban rainwater is effectively absorbed by ecological vegetation, and the project construction cost is saved. Meanwhile, rainwater permeation is effectively carried out, rainwater runoff is reduced through retention and absorption of plants and soil, downstream structures and water are protected, and compared with traditional rainfall flood management measures, the method is low in manufacturing cost and high in economic applicability.
本发明公开了海绵城市改造中雨水花园的施工工法，其技术方案要点是：包括以下步骤：S1、施工准备；S2、基层处理；S3、集水井砌筑及衔接；S4、HDPE防渗层铺设；S5、碎石、砾石垫层与透水盲管铺设；S6、非水平过滤蓄水层施工；S7、种植土回填；S8、排水路缘石及缓冲区施工；S9、绿地栽植。本海绵城市改造中雨水花园的施工方法具有施工管理费用相对较低的优点，雨水花园的建造大大减少了硬质铺装以及市政雨水管道的施工，运用生态植被有效地吸纳城市雨水，节约了项目施工成本。同时，有效地进行雨水的渗透，通过植物和土壤的滞留和吸收减少雨水径流量、保护下游构筑物和水体，它比传统的雨洪管理措施造价费用低，经济适用性强。
