有压输水管道排进气问题的研究

Research of the issue to discharge and injection of pipelines with pressing and injecting water

列举了有压管道输水系统中气体产生的原因、存在条件和危害,论述了防止有压输水管道事故发生的技术措施和设计、施工中应注意的问题,为进一步研究有压管道排(进)气问题提供了参考。

The paper enumerates the reasons how to cause gas＇ occurance in injecting water system with pressure pipelines and its existing conditions and harms. Meanwhile, it also discusses some technical measures to avoid accident＇ occurance for pressure-injecting water pipelines and its problems to be noticed in construction design, which will provide a reference for furtherly studying the issue from discharge and injecting gas with pressure pipelines.
