津潍高铁山东段最大跨度连续梁合龙
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) ...

Core Viewpoint - The successful completion of the 220kV oil Pu/oil Dong line power relocation marks a significant milestone for the construction of the Jinwei High-speed Railway in Dongying District, eliminating major obstacles for the project [1][4]. Group 1: Project Details - The 220kV oil Pu/oil Dong line is a crucial power transmission line operated by State Grid Shandong Electric Power Company, crossing three major railways in Dongying District [3]. - The original line's proximity to the construction area of the Jinwei High-speed Railway posed safety risks, necessitating the relocation to meet operational requirements [3][4]. - The relocation was driven by three main factors: the original line's height of 22 meters was insufficient compared to the required 44.5 meters, the safety coefficient of the original line was 1.0 while the required standard is 1.2, and the crossing angle with the railway was initially 36° but needed to be at least 45° [3]. Group 2: Coordination and Execution - Multiple entities, including State Grid Shandong Electric Power Company, Jinan Railway Bureau, and Huangda Railway Company, coordinated to establish a common power outage schedule for the relocation [4]. - The relocation involved a 13-day power outage, during which five new towers were constructed, and 12,000 meters of conductors were installed, alongside the dismantling of five existing towers [4]. - The successful relocation and restoration of power not only facilitated the construction of the Jinwei High-speed Railway but also ensured safe operations post-commissioning [4].
