- 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.
