摘　　要：在将城市排水合流管改造为雨、污分流管道的过程中,如条件允许可将合流管局部或整体保留用做雨水管,再另外新建污水管道。结合苏州市中心城区完善污水管网工程,介绍了在该市吴县新村内的应用实例。实践表明,保留的合流管能有效地排放正常年份的降雨,甚至是台风暴雨时产生的地面径流。该措施不仅能节约工程投资、缩短工期,还能减少因地面开挖对居民生活造成的不利影响。During modifying urban combined sewer into separated sewers, the urban combined sewer can be locally or totally retained as storm sewer on favorable conditions and new wastewater sewer can be built. Combining the sewer perfection engineering in the central district of Suzhou City, this paper introduces the application example in Wuxian New Village of Suzhou. The results show that the retained combined sewer can effectively discharge rainfall in the normal period and surface runoff caused by typhoon rainstorm. This measure can save the engineering investment, shorten the construction period, and reduce negative impacts of land excavation on inhabitants living.
