在攻坚过程中，项目团队积极推动技术成果转化，发明相关专利。一系列智能化手段与创新成果的应 用，不仅确保了本次滑移的万无一失，还形成了可复制、可推广的跨运营铁路站房施工成套技术，为未 来同类型、高难度的站房建设提供了范本。 据悉，东营南站项目是津潍高铁正线的重要车站。该站房总建筑面积达7.4万平方米，站场规模为7台20 线，采用"线侧+线上式"高架候车设计，建成后最多可聚集2200人。津潍高铁全线贯通后，将显著加强 京津冀、山东半岛与长三角地区的联通。 中铁建工集团有限公司津潍高铁东营南站项目经理杨光介绍，施工过程中，项目团队先在地面完成各滑 移单元的拼接及屋面、幕墙的附属安装，再利用由轨道梁、滑移车及液压爬行器组成的滑移系统进行整 体顶推。在计算机同步控制系统的精确指挥下，站房钢屋盖单元实现精准滑移。 "为实现对滑移过程的毫米级实时控制，我们还构建了智能监测与指挥系统。"杨光介绍，项目团队通过 振弦式应变传感器网络，对滑移轨迹与结构应力进行全过程数据采集，并利用计算机同步控制系统精确 协调所有顶推点动作。L形限位件与精密导轨的配合，则实现系统的动态微调，共同确保上千吨结构平 稳精准就位。 科技日报讯 （记者宋 ...

Core Viewpoint - The article highlights the successful implementation of a pioneering sliding technology for the steel roof structure at the Dongying South Station of the Jinwei High-speed Railway, marking a significant innovation in large-scale roof engineering in China [1][2]. Group 1: Project Overview - The project is undertaken by China Railway Construction Engineering Group, featuring a final sliding unit that includes three steel trusses and an attached metal roofing system, weighing a total of 1,400 tons and spanning 195 meters [1]. - The sliding unit's installation required innovative techniques due to its heavy weight and long span, necessitating the crossing over an operational railway and a dense network of 27.5 kV high-voltage contact lines [1]. Group 2: Construction Techniques - The construction team employed a "ground assembly and overall cumulative sliding" process, transforming complex high-altitude and high-risk operations into safer ground work [1]. - The project involved ground-level assembly of sliding units and the installation of roofing and curtain walls, followed by the use of a sliding system composed of track beams, sliding vehicles, and hydraulic crawlers for the overall push [1]. Group 3: Technological Innovations - To achieve millimeter-level real-time control of the sliding process, an intelligent monitoring and command system was established, utilizing a network of vibrating wire strain sensors for data collection on sliding trajectories and structural stress [2]. - The project team developed several patents, including the "pre-assembled sliding installation device for steel structure roofs" and "welding device for steel structure roof construction," promoting the transformation of technological achievements [2]. - The application of these intelligent methods and innovative results not only ensured the success of the sliding operation but also created a replicable and promotable complete technology for the construction of complex railway station buildings [2].

Core Viewpoint - The successful completion of the first steel roof sliding operation at Dongying South Station marks a significant advancement in railway station construction technology in China, showcasing innovative construction methods and efficiency improvements [1][6]. Group 1: Project Overview - The total building area of Dongying South Station is 74,000 square meters, with a total steel structure weight of 18,500 tons, and a roof projection area of 59,000 square meters [3]. - The project is a key initiative for Dongying City and an important station on the Tianjin-Weifang High-speed Railway [3]. Group 2: Construction Techniques - The project employs a pioneering construction method of "ground assembly + high-altitude docking + high-altitude sliding," which addresses time constraints and safety issues during construction [3][6]. - The sliding operation involved moving a 52-ton steel truss using a 350-ton crawler crane, ensuring precise placement through advanced construction technologies like Tekla [5]. Group 3: Project Timeline and Efficiency - The application of the new sliding technology has reduced the construction timeline by 20-30 days [6]. - The project team will proceed with the construction in four phases, including continuous lifting of roof sections and installation of the roof system [6]. Group 4: Industry Impact - This innovative sliding technology fills a gap in the construction field and provides new ideas and practical experience for similar large-scale roof projects [6]. - The project has been recognized as a key topic by China Railway Construction Group and has passed the project approval by the China Construction Enterprise Management Association [6].
