原标题：官路水库完成主体建设 来源：大众日报 01版 记者从山东省水利厅了解到，官路水库主体工程近日顺利完工。作为山东省近年来新建的兴利库容最大 水库，官路水库计划于2026年下半年充库蓄水。 官路水库位于青岛市胶州市西北的墨水河下游，是山东省构建现代水网的重要结点和骨干工程，总投资 91.45亿元，总库容2.11亿立方米，相当于青岛棘洪滩水库、崂山水库两座水库库容总和。工程建成后， 青岛将告别引黄济青、棘洪滩水库"单渠单库"供水和超负荷运行现状，形成双水源互补格局，大幅提升 青岛乃至胶东半岛水资源统筹调配、供水保障和储备能力，助力区域经济社会高质量发展。 自2023年全面开工以来，项目锚定"百年工程、千年品质"建设目标，克服库区地下水位高、有效施工时 间短、跨汛交叉作业等不利因素，攻坚大体量均质坝填筑、库区断裂带防渗帷幕、大体积联锁块护砌等 施工难点，全面保障水库围坝、泵站和连接线三大主体工程建设高效有序推进。建设过程中持续开 展"样板引路+标准指南+智慧建造"质量闭环体系运行，深入践行绿色施工，创新工法专利10余项，先 后获山东省工程勘察设计成果竞赛奖、优秀工艺奖、绿色施工示范工程等荣誉。（方垒） 想爆料 ...

Core Insights - The construction of the "super reservoir" in Qingdao, with a total investment of 9.145 billion yuan and a total capacity of 211 million cubic meters, is crucial for the city's future development and water security [2][3][6]. Group 1: Project Overview - The project, known as the Guanlu Reservoir, commenced full construction in December 2022 and is currently in the final stages of development [2]. - The reservoir's design capacity is classified as large (Type II), with a total capacity of 211 million cubic meters, equivalent to four Laoshan Reservoirs [4]. - The construction includes various components such as embankments, pumping stations, and river channel diversions, with innovative technologies employed to enhance durability and adaptability [4]. Group 2: Water Resource Challenges - Qingdao faces significant water resource shortages, with per capita water availability at only 186 cubic meters, far below the national average [3]. - The city's current annual water supply capacity is 670 million cubic meters, but projected demand by 2035 is expected to reach 1.6 billion cubic meters, resulting in a shortfall of 930 million cubic meters [3]. Group 3: Benefits and Impact - Once completed, the Guanlu Reservoir will provide an annual water storage capacity of 600 million cubic meters, serving as a vital water source for Qingdao and surrounding areas [6]. - The reservoir will enhance regional water supply security, supporting urban and industrial water needs while addressing the water demands of neighboring cities [6]. - The project aims to transform Qingdao's water supply system from a single-channel approach to a dual-insurance model, significantly improving strategic water reserve capabilities [6][7]. Group 4: Construction Progress - As of now, the project has completed an investment of 6.417 billion yuan, with major construction milestones nearing completion: embankment filling at 99%, pumping station at 93%, and the connecting line at 97% [7]. - The main construction is scheduled for completion by the end of 2025, with full project completion expected in 2026, marking a significant advancement for Qingdao's high-quality development [7].
