关于市政供水管道工程设计若干问题的探讨

Exploration on Some Issues Concerning Municipal Water Supply Pipeline Engineering Design

为降低供水管网漏损率,提高供水安全性与可靠性,越来越多的城市对原有供水管网进行改造。结合工程设计经验,就供水管道管材的选取,管道覆土厚度的确定,管沟回填材料及压实度的要求,附属设施的布置进行探讨。

To reduce leakage percentage of water supply distribution system,also improve water supply security and reliability,more and more cities have been upgrading their original water supply network.Combining engineering design experience,some explorations on selection of water supply pipeline material,determination of thickness of overlying soil,requirements of trench backfill materials,degree of compaction,and arrangement of ancillary facilities were given.
