Study On Optimization Of Mountain City Zoning Water Supply Integration

The national new urbanization planning(2014-2020)was put forwarded On March 16,2014,the country’s historic changes have taken place in urban and rural structure.Is yunxian county,a city with a long history of culture with the characteristics of a typical mountain towns in the country in the new urbanization construction representative.In the process of urbanization,the integration of water supply in cities and towns construction is a key link.For national new urbanization construction planning requirements,the old town in yunxian county of hubei province as an example,analyzes the present situation of water supply,and combined with the region’s terrain features and security requirement,the water source of south-to-north water transfer project in yunxian county implement the integration of urban water supply planning.With the development of national urbanization construction,yunxian county demonstration significance in the implementation of the integration of urban water supply planning.At the same time,the implementation of integration of yunxian county town water supply planning,strengthen the core yunxian county water source protection,to protect the water quality of danjiangkou reservoir and the benefits of south-to-north water transfer project of the play is of great significance for a long time.Integrated water supply planning research in yunxian county town,the main work and conclusions are as follows:(1)according to the characteristics of mountainous city yun county,respectively from the perspectives of water quantity,water pressure,water supply security,analyzes the present situation of water supply,and combining the analysis of characteristics of water supply in the region,puts forward the integration of urban water supply planning and design,and its existing problems are studied.(2)in view of the mountainous small towns water supply network,from the choice of the ways of partitioning of water supply,water supply energy analysis and partitioning optimization method theoretical research on three aspects of water supply pipe,mountain city energy analysis model is put forward and the mountain city of network partition optimization model.City pipe network in mountainous region and water hammer problems were discussed,and corresponding prevention measures are put forward.Finally,according to the theory research,integration of yunxian county town water supply scheme is optimized,implements with the aim of theory research to guide the actual engineering design.(3)Before combining yunxian county chengguan district as an example,through the optimization design of water supply and partition the optimized design of water supply scheme comparison,and to evaluate the safety and reliability of water supply and pipeline construction economy,finally,after using partition optimization design,network with a total investment of cost savings of 1.347 million yuan,8.33%;Network conversion cost,to reduce 417300 yuan,save 21.64%.
