北京市南水北调环线工程2021年防汛工作与思考

Practice and thought of flood prevention in 2021 of Beijing South-to-North water transfer ring pipeline

北京市南水北调环线工程是北京市南水北调配套工程的重要组成部分,承担着向北京市东部、南部主要水厂输送南水北调水的任务。汛期,该工程沿线大量地下阀井易积水威胁井下设备安全,且作为南水北调中线下游工程,水质水量易受工程上游省份险情影响。2021年,北京市南水北调环线管理处围绕“工程沿线阀井积水防治”及“水质水量调度”两大重点任务,通过全面落实“四预”(预报、预警、预案和预演)、建设智能阀井实现积水监测和自动抽排、科学调度化解河南省2021年“7·20”暴雨南水北调水短期浑浊风险等措施,确保了所辖工程的平稳度汛和供水安全。基于防汛实际,提出了拓宽信息共享渠道、提升技术自研水平、加快推进工程遗留问题解决的工作建议。

Beijing South-to-North water transfer ring pipeline is an important part of Beijing South-to-North Water Diversion project,which undertakes the task of transporting the South-to-North water to the main water plants in the East and South of Beijing.In flood season,a large number of underground wells along the pipeline are prone to runoff ponding,threatening the safety of underground equipment,and as the pipeline is the downstream of the middle route of South-to-North Water Transfer,the water quality and quantity are vulnerable to the dangerous situations of the upstream provinces.In 2021,The Ring Pipeline Management Department focused on two key tasks of"prevention and control of well ponding"and"water quality and quantity dispatching",took actions such as fully implementing the"forecast,early warning,rehearsal and plan",developing intelligent wells to realize ponding monitoring and automatic pumping,scientifically dispatching to dispose the yellow water risk of South-to-North Water Transfer due to"2021.7.20"rainstorm in Henan,finally ensured the safety of the pipeline operating and water supply.Based on the practice of flood prevention work,some suggestions are further proposed,such as broadening the information sharing channels,improving the technology research level,and accelerating the solution of the remaining problems of the project.
