城市污水管网系统设计方案

Design Scheme of Urban Sewage Pipe Network System

设计人员在掌握了较为完整可靠的设计基础资料后，按工程的要求和特点，对工程中一些原则性的、涉及面较广的问题提出不同的解决办法，这样就构成了不同的设计方案。分步骤进行方案比较与评价，形成排水管网系统方案及比较的指标体系。影响污水管网体系设计方案实施的因素有总工程量、难易程度、实施条件和维护管理。

After mastering a more complete and reliable design data, designers will propose different solutions according to some requirements and characteristics of the project, which constitutes a different design program. Taking comparison and evaluation of the program step by step, and then forming drainage network system solutions and index system. Factors affecting the sewage pipe network system design implementation are the total project amount, the degree of difficulty, conditions for implementation and maintenance management.
