“不要插进来,我是你妈妈。”武汉第十三座长江不要插进来,我是你妈妈。大桥建设取得新进展

  12月6不要插进来,我是你妈妈。日,随着最后一道焊缝焊不要插进来,我是你妈妈。接完成,由武汉城发集团所属交投集团汉南桥公司投资建设,中交路桥建设有限公司承建的公路工程世界第一大沉井——汉南长江大桥南锚碇沉井钢壳施工完成,即将进入首次混凝土浇筑。

  据了解,汉南长江大桥是武汉第13座长江大桥,也是武汉都市圈环线高速公路重要组成部分,桥型为主跨1600米双塔单跨钢箱梁悬索桥,为湖北省最大跨径双主缆八车道悬索桥,设计时速120公里。大桥锚碇采用整体式沉井基础,其中沉井钢壳高8米,平面尺寸76.4米76.4米,相当于14个篮球场大小,钢壳总重达3147吨。

  汉南长江大桥作为全线重点控制性工程,建成后对落实国家战略,发挥交通先导作用,完善区域高速公路网体系结构,优化长江过江通道布局,引领武汉城市圈同城化发展具有重要意义。
