中新社湖北宜昌10月10日电 (郭晓莹 董晓斌 卢西奥)葛洲坝航运扩能上下游围堰10日正式启动施工。这标志着作为三峡水运新通道工程重要组成部分的葛洲坝航运扩能全面进入主体施工阶段。

葛洲坝航运扩能位于已建成的葛洲坝水利枢纽左岸。工程将拆除既有三号船闸,并在原址新建两座闸室有效尺度为280米×40米×8米(长×宽×槛上最小水深)的万吨级船闸。未来,万吨级单船可顺畅通过葛洲坝枢纽。

围堰是葛洲坝航运扩能建设的第一道关键关卡,当日施工的两道围堰将与岸坡等共同围护施工区域,为万吨级新船闸干地施工创造先决条件。

上游围堰为Ⅰ级临时水工建筑物,防洪标准参照葛洲坝主坝设置,全长835.94米,最大堰高28米,总工期24个月。下游围堰由混凝土围堰、钢管桩围堰、土石围堰和岩埂围堰四部分组成,总长960.85米。

“本次围堰施工区域地处葛洲坝枢纽核心通航水域,既要抢抓枯水窗口期保障围堰按期闭气,又要统筹做好通航保障等各项工作。”三峡集团三峡新通道公司葛洲坝扩能工程管理部副主任王霄表示,项目团队将强化全过程安全质量管控,高标准推进围堰建设,为后续船闸主体施工筑牢坚实基础。

工程建设期间,葛洲坝二号船闸将保持运行,相关航段按照通航管理部门发布的通告实施通航管控。

长江三峡通航管理局通航安全处副处长兰毓峰表示,通航管理部门将在59千米的三峡河段布设1个通航应急保障中心,配套太平溪、乐天溪、黄柏河、庙咀4个综合站点,从船舶过坝联动控制、过坝调度、水上安全监管、航道维护、重点物资保障及船舶待闸服务等方面强化措施,保障三峡水运新通道工程建设期长江黄金水道安全有序畅通。

三峡水运新通道工程于2026年6月8日开工,是三峡工程之后长江干线上集水利、航运、生态等功能于一体的最大综合性工程,是“十五五”时期中国开工建设的首个重大标志性工程。(完)
