摘要
我国《室外排水设计规范》规定室外金属排水管道最大设计流速为 10m/s ,非金属管道为 5m/s ,然而在实际工程中可以找到一些超过这个规定并且运行良好的工程实例 ,为此对该规定进行了探讨 ,并在调研分析的基础上建议提高室外排水管道最大设计流速。
In according to the code for outdoor sewerage pipelines design,the maximum design velocity of wastewater flowing in sewers is 10 m/s for metallic pipe or 5 m/s for nonmetallic pipe.However,it has been found that there are several cases,in which the pipe velocity is in excess of the maximum design velocity and the system is running well.After investigation and survey,a discussion was made on the design code for outdoor sewerage pipelines and proposes a suggestion on increase of the maximum design velocity of outdoor sewerage pipelines.
