“人c交ZZZ0OOZZZ0002022”清花高速北人c交ZZZ0OOZZZ0002022江特大桥首个主塔封顶

  中新人c交ZZZ0OOZZZ0002022社清远12月25日电 (蔡敏人c交ZZZ0OOZZZ0002022婕 周顺)粤港澳大湾区工程清花高速(清远清新至广州花都高速公路)北江特大桥首个主塔25日封顶。

  清花高速项目起于广东省清远市北侧,连入广州花都西二环高速,全长54公里。北江特大桥主桥是清花高速项目的关键控制性工程。主桥全长1440米,为主跨360米的钻石型四塔双索面半漂浮体系混凝土梁斜拉桥,桥面总宽37.6米,共设置四座主塔。

  大桥以“凤凰展翅”为主题,将凤凰羽翼的弧形层叠曲线应用于主塔造型,造型优美独特,与清远“凤城”的称号相呼应,有鲜明的地域特色,建成后将成为清远市的新地标。

  本次封顶的5号主塔总高144.7米,共28节段,约50层楼高。塔冠采用钢壳结构,由钢结构部分和钢混结合段两部分组成,总高度15.5米。

  据中铁大桥局清花高速项目总工程师路灵伟介绍,目前北江特大桥主塔均已进入上横梁施工阶段,主梁全面转入牵索挂篮施工。

  路灵伟称,清花高速建成后将有利于构建佛山东部经清远向北通道,对强化粤港澳大湾区对清远的辐射作用,推进广(州)清(远)一体化发展具有重要意义。(完)
