Study On The Establishment And Optimal Design Of Funing District Water Supply Network Based On Hydraulic Model

With the continuous improvement of the domestic economic level,the urbanization process has become more and more deep,and the number of small and medium-sized cities and towns has increased,and the demand for urban water supply facilities and other infrastructure construction has also increased.As a result,the urban water supply demand has exceeded the water distribution capacity of the pipe network to a certain extent.Reasonable optimization of infrastructure and supporting facilities has now become a core issue in the construction of a new urban area.This article first analyzes and studies the objective conditions of Funing District to determine the scale of the urban area and lay the foundation for the next water demand forecast and water source selection.Then the scale of the entire city is determined,according to relevant regulations,the comprehensive water consumption index method is used to get the water demand of this area to be 1.0×10~5m~3/d.After the analysis and calculation of the above content,reasonable planning,design and research of the water supply system in Funing District are carried out to determine the rationality of the pipe materials,pipe diameter,pressure and direction of the pipes selected for the water transmission and distribution pipelines of the urban water supply network,so as Ensure that the water supply of this book is stable,the water quality is safe,and the economic benefits are maximized.The second is to take the optimization design of the water supply network transformation in Funing District as a specific engineering case,and use the EPANET software to construct the hydraulic model of the water supply network.Aiming at the simulation of the current pipe network status,the pipe network accident check,and the EPANET software is used to quickly identify the pipe network fire check points,and efficiently realize the pipe network fire check and water supply evaluation of the entire Funing District.Based on the simulation of fire fighting conditions,the influence of fire on the water supply of downstream nodes is analyzed.Based on the actual situation of the project,two different main ring network transformation plans were formulated.After that,simulation analysis was adopted to construct a multi-objective decision-making evaluation system to evaluate the simulation situation of the plan.From the perspective of technology and economy,the plan was analyzed as a whole,and the qualitative evaluation was turned into a quantitative calculation that can be measured by data.So as to determine the optimal plan.
