“拢萝卜又痛又叫”金沙江上游拉哇水拢萝卜又痛又叫电站大坝填筑突破1000万立方米

  中新拢萝卜又痛又叫网成都10月30日电 (禹拢萝卜又痛又叫娇艳 侯树芃)10月30日,金沙江上游拉哇水电站大坝累计填筑量突破1000万立方米大关,填筑高度攀升至125米,向着2026年首批机组投产发电目标稳步迈进。

  拉哇水电站由华电金沙江上游水电开发有限公司(以下简称华电金上公司)开发建设,位于四川巴塘县和西藏芒康县境内,是金沙江上游规划“一库十三级”的第8级电站。电站装机容量200万千瓦,多年平均发电量90.89亿千瓦时,大坝最大坝高239米,大坝设计总填筑量1661万立方米。

  华电金上公司针对拉哇水电站地质条件复杂、填筑工期紧张、高原地区机械降效明显等诸多难题,联合多家科研单位开发“拉哇云”智能建造系统,对大坝填筑全过程智能感知、分析与馈控,全面应用无人碾压、智能物料、智能加水、智能摊铺等技术联动“智慧大坝”协同指挥平台,通过精准监控和主动纠偏,全面规避人工碾压精度低、质量控制难度大等问题,保障高坝填筑碾压质量。大坝日填筑量突破3.3万立方米,施工进度快、安全稳、质量优。

  截至目前,大坝填筑标准碾压遍数覆盖率均超过97%以上,一次质检合格率100%,优良率达到98.4%。参与研究的《复杂条件高坝工程智能建设关键技术及应用》荣获国家科学技术进步奖二等奖,实现了智能建造技术在传统坝工建设领域的突破。

  建设过程中,华电金上公司积极践行“绿色低碳、清洁美丽”环保理念,因地制宜探索新能源技术在工程建设过程中的应用落地,开创性地在高原寒冷地区全面应用新能源自卸车运输填筑坝料,降低工程建设对传统化石能源的依赖,实现“零排放”。大坝填筑期间,新能源自卸车的投入使用预计可减少柴油消耗约2027.77万升,可累计减少二氧化碳排放量6.4万吨,真正实现“低碳工地”目标,助力高原生态环境保护。电站建成后,每年可节省标煤282万吨,减少二氧化碳排放685万吨。(完)
