作为高速铁路的“神经中枢”与“动力之源”,四电工程涵盖通信、信号、电力和牵引供电等多个子专业,技术标准高、接口交叉多。

C | 接触网是铁路牵引供电专业的主构架,由接触网悬挂、支持装置、定位装置、支柱与基础等组成。
为确保接触网首杆成功组立,山东铁投济青高铁公司会同潍宿高铁至青岛连接线四电施工2标施工单位中铁武汉电气化局科学谋划、统筹安排,制定了专项施工方案和作业指导书,严把支柱运输、验收、组立等关键工序,严格作业流程和工艺标准,将安装后误差控制在毫米级,为全线接触网支柱组立施工打造首件样板工程。
当天,“站后四电工程”强国示范劳动竞赛同步启动,标段各班组围绕安全管控、质量创优、节点推进开展攻坚,全力推动各项目标任务落地见效。潍宿高铁至青岛连接线是国家“八纵八横”高速铁路网京沪辅助通道与沿海通道的重要联络线,线路全长108.78公里,设计时速350公里,串联青岛西海岸新区、潍坊诸城、日照五莲,打通青岛直达京沪二线的快速通道。
项目建成后,将大幅缩短胶东半岛往返京津冀、长三角的通行时间,进一步完善山东半岛立体铁路交通网,为区域经济协同发展注入新的动力。
