Analysis of Rainwater and Sewage Improvement Project in Community of Chaoyang District,Beijing City
This article analyzes the rainwater and sewage renovation project for a residential area in Chaoyang District,Beijing City,which has no drainage outlet for sewage and serious waterlogging during the rainy season.A survey is conducted on the current situation of the community's pipe-lines,surrounding municipal conditions,and existing drainage pipeline problems,so as to verify whether the municipal pipeline network and current river channels meet the requirements for rainwater access in the community.At the same time,after fully understanding the renovation needs,the ren-ovation project of the current rainwater and sewage pipelines is optimized and designed.In view of the large precipitation during the rainstorm period,a rainwater storage tank is set in front of the rainwater lift pump station to reduce the downstream rainwater discharge pressure.During the design process of the rainwater lift pump station,calculations and scheme designs are carried out for both traditional and integrated pump stations,and the traditional pump station is ultimately selected as the better option.The optimization plan has provided drainage outlets for both rainwater and sewage in the community,effectively improving the problem of waterlogging in the community.
