摘要:- 北京老城區現狀排水系統大部分為雨污合流系統，汛期溢流污水常對下游河道造成一定程度的水環境污染。胡同平房區作為北京老城區的主要建筑代表形式，其排水系統的雨污分流改造工程存在一定的困難，胡同通常較窄、地下空間狹小，無法滿足市政管線的敷設要求。因此，有必要結合老城胡同平房區的實施條件盡可能選擇適宜的形式實現雨污分流改造。分析了北京老城胡同平房區現狀排水系統存在的問題及雨污分流改造的難點，總結了胡同和平房院落內的雨污分流改造方式。并以北京南鑼鼓巷地區的雨污分流改造為實例，采用模型技術及豎向優化的方法,探索采用管溝和胡同路面排水相結合的方式實現老城胡同平房區的雨污分流改造，為老城區的雨污分流改造提供思路和技術方法。
Abstract:- Most of the current drainage systems in Beijing old town are combined systems. In the flood season, the overflow often causes a certain extent of water pollution to the downstream rivers. As the main representative form of Beijing old town, Hutong cottage area has certain engineering difficulties in the rainwater and sewage diversion transformation. Most of the Hutong areas have narrow width and limited underground space, which cannot meet the laying requirements of all municipal pipelines. Therefore, it is necessary to combine the implementation conditions of Hutong cottage area to select the appropriate form to transform the rainwater and sewage drainage system. This paper analyzed the existing problems of the drainage system and the difficulties of the rainwater and sewage diversion transformation in the Hutong cottage area of Beijing old town, and summarized the transformation mode of rainwater and sewage diversion in the Hutong road and courtyard. Taking the rainwater and sewage diversion transformation in the Nanluoguxiang area of Beijing as an example, this paper used model technology and vertical optimization methods to explore the combination of pipe drainage and road drainage to meet the rainwater and sewage diversion in the Hutong cottage area, which could provide the transformation ideas and technical methods for the combined sewer separation of the old town area.
