基于景观提升的镇江古运河雨水系统构建研究
Study on the Enhancement of Rainwater System for Zhenjiang Ancient Canal by Landscape Improvement Works

基于镇江古运河上段高落差的河岸空间、独特的地理位置与人文内涵,依据海绵城市的理论与技术,在保持古运河河坡稳定的前提下,兼顾景观提升目标,通过下沉式雨水花园、多层级雨水滤蓄带、人行道雨水收集系统三种雨水收集过滤形式,创新性构建镇江古运河特色雨水收集系统。对同类项目的实践具有指导借鉴意义,对海绵城市技术在老城区雨水管理中的运用具有示范作用。
With consideration of steep gradient of riverbank,unique geographical location and humanistic connotation within the upper region of the ancient canal in Zhenjiang,and based on the theory and technology of “Sponge City” together with maintaining the ancient canal river slope stability,the improvement works of the landscape were carried out by adopting sunken garden,rainwater storage,multi level filter with pavement rainwater collection system.By using these innovation systems of rainwater collection and filtering,it has not only effectively enhanced the rainwater system of Zhenjiang ancient canal,but also demonstrated an important and excellent guideline for practice of similar projects in future.These landscape measures also manifest as an exemplary role in the application of the “Sponge City” Technical Guidelines of this ancient city’s rainwater management.
