Comprehensive functional rainwater garden under saline-alkali soil condition
The invention discloses a comprehensive functional rainwater garden under the saline-alkali soil condition, and belongs to the technical field of sponge city construction. According to the method, an LID blind pipe is adopted to discharge underground water carrying saline-alkali components in time when the underground water is at a seasonal high water level. Permeable geotextile is adopted to separate base plain soil from graded broken stone, and two-cloth and one-membrane geotextile is adopted close to the road side. The rainwater garden is purified by laying a medium soil layer. The landscape of the rainwater garden is improved by laying pine barks on the surface of the rainwater garden and spreading pebbles. The mud content of the graded broken stone is less than or equal to 1%, the crushing value is less than or equal to 15%, and layered paving is adopted. The medium soil layer is prepared from coconut residua, volcanic sand, river sand and planting soil according to the mixing ratio of 3: 1: 5: 1. According to the comprehensive functional rainwater garden, the problems that the rainwater garden is unsmooth in regulation and storage and plants in the rainwater garden are poor in growth vigor under the saline-alkali soil condition can be effectively solved.
本发明公开了盐碱土质条件下的综合功能型雨水花园，属于海绵城市建设技术领域，该方法采用LID盲管及时排放在地下水季节性高水位时携带盐碱成分的地下水；采用透水土工布分隔基层素土与级配碎石，靠近道路侧采用两布一膜土工布；通过铺设介质土层实现雨水花园的净化；通过雨水花园表皮铺设松树皮及卵石散布提升雨水花园的景观；所述级配碎石含泥量≤1％，压碎值≤15％，分层摊铺；所述介质土层配合比为椰糠：火山砂：河砂：种植土＝3：1：5：1。本发明能够有效解决盐碱土质条件下雨水花园调蓄不畅、雨水花园内植物长势不良的问题。
