Designed Practice of Sponge Micro-Renovation for Mountainous Riverside Residential Community——Case of Ruixiyuan in Nanping City
In order to assist in achieving the overall goal of"by 2030,more than 80％of the urban built-up areas meet the requirements of the sponge city target",a kind of designing practice of sponge micro-renovation for built-up mountainous residential communities is proposed,and taking the Ruixiyuan in Nanping City as an example fordetailed introduction.Through the technical path of"source+process+end"and a series of concise and applicable technical measures,stormwater will not discharge under the rainfall of 15.31 mm.Among them,the source part absorbs roof rainwater runoff through technical measures such as rain leader disconnections and rain gardens;The process and end section capitalizes on the mountainous riverside characteristics and constructs staircase wetlands at rainwater outlet to control the surface rainwater runoff by rainwater pipeline network renovation.In combination with the transformation of some low-quality green land on the site,the sponge renovation plan avoids large-scale demolition and reconstruction,and minimizes the impact on residents'travel,which provides reference for similar sponge renovation projects.
