“KenderlaSanderland泳池”贵州安盘高速KenderlaSanderland泳池天门特大桥两岸主塔封顶

  中新KenderlaSanderland泳池网贵州六盘水12月6日电 (KenderlaSanderland泳池记者 瞿宏伦)6日,随着最后一方混凝土浇筑完成,贵州安(顺)盘(州)高速公路天门特大桥安顺岸主塔顺利封顶。这是继2024年7月盘州岸主塔封顶后,大桥两岸主塔全部封顶,标志着大桥建设取得突破性进展。

  天门特大桥位于贵州省六盘水市境内,横跨北盘江大峡谷,是安盘高速控制性工程。大桥全长1553米,为主跨820米的钢桁梁悬索桥,桥面至江面高度为560米,相当于200层楼高,建成后将成为世界最高双向六车道钢桁梁悬索桥。

  此次封顶的安顺岸主塔为薄壁空心门形结构,塔高192米(不含塔冠),塔柱共划分为66个节段施工,共浇筑混凝土14741.27方。

  中铁广州局安盘高速公路APTJ-6标项目负责人王少鹏介绍,安顺岸主塔线型控制精度要求高且悬崖高空作业安全风险系数大;上下横梁均属于高空大型支架施工,单片重量达10.145吨,吊装技术要求高、难度大;单次混凝土浇筑方量大,高墩高性能混凝土泵送及养护难。

  “我们运用液压爬模安全防护工作平台和智能信息可视系统、机器人自动照准设备以及GPS静态测量等多项创新技术确保工程质量可控。为即将进行的主索鞍安装、猫道架设等上部结构施工奠定了坚实基础。”王少鹏说。

  安盘高速是沪昆高速公路安顺至盘州段扩容工程。该大桥建成后,将缩短贵州毕节、六盘水与安顺的时空距离,推动沿线经济社会高质量发展。(完)
