城市污水管网优化设计探究

Research on Optimization Design of Urban Sewage Pipe Network

文中重点探究了城市污水管网在现有条件下的优化设计。结合目前城市污水管网使用中存在的问题,分别从充满度、流速、管径、坡度、埋深、管材、衔接等方面对污水管网进行优化,并通过污水管网工程投资费用计算,在比较单条管道投资费用的基础上,对整个管网的总投资做量化对比,使工程投资成本最小,实现管网的优化。

This paper focuses on the optimal design of urban sewage pipe network under the existing conditions. Combined with the existing problems and planning of urban sewage pipe network, the optimization of sewage pipe network was carried out from the aspects of fullness,flow velocity, pipe diameter, slope, buried depth, pipe material and connection, etc., through calculating and comparing the investment cost of sewage pipe network project, on the basis of comparing the investment cost of single pipe, at the same time, the total investment of the whole pipe network is compared quantitatively so as to minimize the project investment and realize the optimization of the pipe network.
