介绍了小区庭院给水管网改造在设计过程中如何进行现场踏勘和管线布置,对工程中应用的球墨铸铁管、聚乙烯给水管、钢塑复合管3种管材从性能、造价、施工等方面进行了对比分析,并通过工程实例对优化设计过程进行了阐述。
This paper introduces how to reconstruct the courtyard water supply network in the design process and how to carry out on-the-spot reconnaissance and pipeline layout. The three types of ductile iron pipe, polyethylene water pipe and steel-plastic composite pipe used in the project are made from the aspects of performance, cost, construction and so on The comparative analysis is carried out, and the optimization design process is expounded through the engineering examples.
