城市化进程的加快,增加了城市管网的建设数量,选择城市给排水管道材质的时候,需要考虑外部荷载、内压、管径、敷设区域地质、管材供应等情况,遵守运行耐久、安全、维护方便、减少漏损、防止二次污染、经济合理的基本原则,综合分析安全、经济以及技术,以此本文着重阐述了市政给水排水管道设计的技术措施。
The speeding up of urbanization has increased the number of urban pipe networks. When choosing the materials for urban water supply and drainage pipelines, external loads, internal pressures, pipe diameters, the geology of the laying area and the supply of pipe materials need to be taken into account. Operation in terms of durability, safety, Maintenance convenience, reduce leakage, prevent secondary pollution, economic and reasonable basic principles, a comprehensive analysis of safety, economy and technology, so this article focuses on the municipal water supply and drainage pipe design of technical measures.
