Da Zhong Ri Bao· 2025-08-10 00:30
津潍高铁是国家"八纵八横"高铁骨架的重要"一纵",是京沪辅助通道和沿海通道的共同组成部分。 线路北起天津滨海站,南至济青高铁潍坊北站,全长约348.9公里。 8月9日凌晨,随着最后一斗混凝土精准注入预留接口,由中铁十四局承建的津潍高铁关键控制性工 程——东寿特大桥跨荣乌高速连续梁成功合龙,为津潍高铁通车建设按下"加速键"。 据介绍,东寿特大桥跨荣乌高速连续梁是津潍高铁山东段最大跨度连续梁。工程施工干扰因素多、 安全风险较大、施工技术要求高,连续梁成功合龙为下一步架梁和无砟轨道施工奠定了基础。 作为交通强国山东示范区的重大标志性工程,津潍高铁建成通车后,将结束寿光不通高铁的历史, 填补鲁北地区高铁发展空白。与济青高铁在潍坊北站相连,从此青岛到北京、天津,不用再绕行济南。 (记者 王晓芳 陈景郁) ...
