南水北调渠道抽排泵站运行工况研究

Study on Operation Condition of Pumping and Drainage Station in the Channel of Soutto-North Water Transfer Project

南水北调工程事关战略全局、长远发展、人民福祉。抽排泵站是南水北调总干渠高地下水位段调节地下水位确保渠道安全的重要保证建筑物之一,文章主要通过背景分析、失效逆止阀对抽排泵站的影响分析、泵站抽排过程对水位的影响分析(抽排井工作泵停止值调整对工作水泵抽排时间影响)、安全监测数据与抽排泵站地下水位的分析与研究,探讨了抽排泵站运行工况下各因素之间的关联。在“7·20”特大暴雨期间该理论成果的运用为工程消除了安全隐患,确保了工程运行安全,希望文章能够抛砖引玉为其他类似工程的设计及运行提供参考。

The South-to-North Water Transfer Project is related to the overall strategic situation,long-term development and people’s well-being.The pumping and drainage station is one of the important guarantee buildings for regulating the groundwater level in the high water level section of the main canal of the South-to-North Water Transfer Project to ensure the safety of the channel.This paper mainly analyzes and studies the background analysis,the influence of the failure check valve on the pumping and drainage pump station,the influence of the pumping and drainage process on the water level(the influence of the adjustment of the stop value of the working pump of the pumping and drainage well on the pumping and drainage time of the working pump),the safety monitoring data and the groundwater level of the pumping and drainage pump station.The relationship between various factors under the operation condition of pumping and drainage pump station is discussed.During the7.20 rainstorm,the application of the theoretical results eliminated the potential safety hazards for the project and ensured the safe operation of the project.It is hoped that this paper can offer a reference for the design and operation of other similar projects.
