摘要
在供水管线工程中,供水工程管道投资一般占工程投资的1/2以上,管材费用约占管道工程投资2/3甚至更多,合理选择管材的种类对工程的安全及投资具有重大意义。本文以察布察尔县自流灌区管材的比选为例,就管材在水力特性、水头损失、综合造价、运行管理等方面进行定性分析,总结管材优缺点及在工程中的使用情况进行探讨,为大中型灌区自压管道管材的选择提供依据。
In the water supply pipeline project,the water supply pipeline project investment usu-ally accounts for more than 1/2 in construction investment,pipe costs accounted for about 2/3 or evenmore investment in pipeline engineering, it is of great significance for the safety and investment of theproject to choose the type of pipe reasonably.In this paper,gravity irrigation pipe Qapqal county is se-lected as an example, from the aspects of hydraulic characteristics, head loss, comprehensive cost,op-eration and management qualitative analysis is made, and the advantages and disadvantages of the useof pipes in engineering were discussed,which provides the basis for large and medium-sized irrigationto select the materials of the self-pressure pipeline.
