摘　　要：历史文化街区的基础设施改造一直是改造中的难点和痛点,而雨污分流改造则由于现有街区建筑地基较浅、街区狭窄和现有管线错综复杂,更增大了雨污水分流改造的实施难度。该项目雨污分流设计结合街区现有排水体系,针对现状地形坡度特点,因地制宜采取了不同的排水体制,并提出三种不同的改造策略,很好地实施了雨污分流改造,既实现了污水的收集排放,也消除了街区长久以来的内涝点。The infrastructure reconstruction of historical cultural blocks is always the difficulty and pain point in the reconstruction process.And the reconstruction of rainwater and sewage separation increases the difficulty in the implementation of rainwater and sewage separation reconstruction even more due to the shallow foundation of existing block buildings,the narrow blocks and the complex existing pipelines.Combined with the existing drainage system of the block,and aiming at the characteristics of the current terrain slope during the design of rainwater and sewage separation of the project,the different drainage systems are adopted according to the local conditions,and three different reconstruction strategies are proposed better to implement the reconstruction of rainwater and sewage separation,which not only achieves the collection and discharge of sewage,but also eliminates the waterlogging points for a long time in the block.
