突泉县水资源调配工程方案及关键技术研究

Research on water transfer project of Tuquan county and its key techniques

概括总结了突泉县水资源开发利用现状与存在的4个主要问题。针对突泉县"工程性缺水"特征,提出了突泉县水资源调配工程的推荐方案及分期实施建议。推荐方案包括突泉镇第二水源地建设工程,大、小额木特河水资源调配工程和蛟流河水资源调配工程等3个相对独立的分项工程;建议分两期实施,并力争2020年前建成运行。初步研究了突泉县水资源调配工程中的——水资源供需平衡计算、调水率与洪水资源化利用、渠道泥沙设计与水库清淤、渠道蒸发与渗漏损失估算、渠首渠道防冻设计、水体纳污能力计算等6个关键问题与技术。

The paper summarized the present situation of water resources development and utilization of Tuquan County and 4 related major problems. Based on the characteristics of water shortage in engineering of the County due to lack of water transferring project, it proposed the recommended scheme and two - phase implementation for the water transfer project of Tuquan County. The scheme consisted of 3 subprojects such as the second water source project of Tuquan town, the water transfer project between large and small Ermute Rivers and the water transfer project of Jiaoliu River. The project will be completed before 2020. Finally, the paper preliminarily researched the six key issues or techniques of the project such as supply - demand balance of water resources, water transfer ratio, floodwater utilization, canal sediment design , reservoir dredging, canal water loss rate from evaporation and seepage, antifreeze design for headwork and canal, and environmental carrying capacity.
