“四川XXXXXLMEDJYF”广西横钦高四川XXXXXLMEDJYF速公路郁江特大桥北岸主塔封顶

  中新四川XXXXXLMEDJYF网南宁11月29日电 (杨四川XXXXXLMEDJYF志雄 曾文豪 张子禾)11月29日,随着最后一方混凝土经地泵入模,广西横钦高速公路郁江特大桥北岸主塔顺利封顶,该大桥建设取得突破性进展。

  由中国能建葛洲坝一公司承建的横钦高速公路,是西部陆海新通道中高速路网主通道。郁江特大桥是横钦高速公路的关键控制性工程,位于广西南宁横州市横州镇与那阳镇之间,是一座主跨度580米的双塔混合梁斜拉桥,分南北两座主塔,桥梁总长2200米,采用“三角塔”造型。

  此次封顶的郁江特大桥北岸主塔高169米,塔柱分为29节,截面呈“正六边形”结构,第29节浇筑方量达160立方米。

  据横钦高速公路总承包项目部党支部书记刘权厚介绍,自2023年3月18日桩基施工以来,项目团队克服重重困难,历时622天,完成了主塔的封顶任务。

  为确保浇筑工作顺利进行,项目团队对施工方案进行多次优化,对管理流程进行了精细化调整。在建设过程中,主塔塔身施工采用125型液压自动爬模系统,该爬升机构具有自动导向、液压升降、自动复位等锁定机构,能实现架体与导轨互爬的功能,大幅提升施工过程中的安全性、稳定性及施工效率。

  据了解,横钦高速公路北起横州市云表镇,南至钦州市犀牛脚镇,主线全长约160.875公里,采取双向四车道设计,设计速度120公里/小时,路基宽度26.5米,是《广西实施国家战略高速公路网规划(2018-2030)》布局方案中“纵5”的重要组成部分。

  截至目前,横钦高速已完成土方开挖回填6466万立方米、桩基4381根、墩柱2330根、涵洞26627米。横钦高速建成后,将进一步完善当地交通网络,成为广西东部地区出海新通道,同时将加速珠江—西江经济带及北部湾城市群建设。(完)
