摘要
上海市崇明东滩启动区供水工程为管径DN150～DN600,总长约34 km的配水管网。配水管网布置范围约为12.51 km2,管网以环状网为主,与枝状网相结合。通过对2种供水系统方案比选,运用管网水力计算软件进行管网平差计算,分析计算结果,同时考虑安全性、合理性和经济性,推荐方案1(无增压泵站)为最优方案。
Dongtan Starting Area water supply project in Chongming of Shanghai is adopting the total length of about 34 km distribution system pipelines with the diameters from DN150 to DN600.The layout scale of the distribution system is about 12.51 km2 with circular network mainly and combined with branch-shaped network.Through a plan selection of two water supply systems,the pipe network balancing calculation is done by pipelines network water force calculation software to analyze the results.Meanwhile,Plan 1(without booster bumping station) is recommended to be the best one according to safety,rationality and economic efficiency.
