丘陵地区大口径输水管线工程若干问题探讨

Approach of a large diameter water conveyance pipeline design in hilly area

以罗安达供水工程中DN900输水管线工程为例,对丘陵地区大口径输水管线设计中的管材选择、水锤防护、排气阀设置、管道的稳定等问题进行了探讨,并提出了解决方案,以确保输水管线工程设计经济、合理。

Based on the characteristics of a 11.13 km water conveyance pipeline of water supply project in Luanda, Angola, some design issues of the large diameter water conveyance pipeline in hilly area, such as selection of pipe material, water hammer prevention, setting of discharge valve and stability of pipeline were discussed. The corresponding schemes were put forward to ensure the economic and reasonable design in the water supply project.
