“男生和女生一起相差差差30免费观看”中国单体最长最男生和女生一起相差差差30免费观看重跨铁路悬浇T构转体桥成功转体

  12月1男生和女生一起相差差差30免费观看1日,中国单体最长、最重跨铁路男生和女生一起相差差差30免费观看悬浇T构转体桥——云南宣(威)富(源)高速公路上跨盘西铁路立交桥成功转体,刷新中国悬浇法施工跨铁路T型刚构转体桥新纪录。

  该立交桥位于云南省曲靖市富源县杨二冲附近,上跨盘西铁路,离铁路最近的墩柱距离男生和女生一起相差差差30免费观看仅有17.6米。为最大限度减少对铁路运输的影响,该桥采用转体法施工,平行于铁路线路挂篮悬臂浇筑梁体,最后球铰转动使桥梁跨越铁路后与设计桥位完美重合。

  大桥转体梁长度为169米,主体桥面宽25.7米,桥面面积相当于10个标准篮球场,转体重量2.4万吨,是目前中国单体最长、最重的跨铁路悬浇T构转体桥。(制作 白玲 视频来源 云南建投集团)
