F市多井水源给水管网水力建模及改扩建分析
|
摘要
针对采用多井水源的F市给水管网,建立了水力模型,并根据管网现状监测资料进行了模型校验。在此基础上,针对该市引水工程项目,拟定了4套管网改扩建方案,从建设运营成本和降低爆管风险两个方面进行了分析,根据计算结果确定了经济性和安全性较佳的方案。最后利用水力模型成果查询管网中流速较大的管段,有选择性地进行扩径改造,消除了管网瓶颈,为管网优化运行和改扩建提供了科学依据。
A hydraulic model was established for the water distribution network of F city with multi-well water source, and the model was calibrated according to the monitoring data of pipe network. On this basis, develop a 4 sets of pipe network expansion program for the city water diversion project, analyze from two aspects of the costs of construction and operating,and reducing the risk of bursting, and determine the best program in economy and safety according to the calculation results. Finally, the hydraulic model results are used to find the pipe sections with large flow velocity in the pipe network, and the pipe sections were selectively reconstructed with larger diameter, which eliminates the pipe network bottleneck and provides a scientific basis for the optimal operation and expansion of the pipe network.
