中新网北京10月31日电 (记者 贾天勇)记者从中国铁路北京局集团有限公司获悉：10月31日上午，在位于河北省保定市的石雄铁路定州区段建设现场，经过大型机械精准控制，首榀重达数百吨的预制箱梁稳稳落于桥墩上，标志着石雄铁路建设进入桥梁架设阶段，为后续无砟轨道铺设打下了坚实基础。
为确保箱梁架设顺利进行，京津冀城际铁路投资有限公司组织各参建单位主动攻关，以“智能化、高效化、绿色化”为导向，打造全流程智能化建造体系：采用智能震动上料系统实现砂石骨料精准配比与匀速输送，从源头保障混凝土品质；在施工中应用橡胶棒拔管穿管机实现管道铺设自动化，彻底消除人工误差。大量智能装备的投入应用，使得箱梁从建造到架设实现了“精准化、标准化、高效化”，为后续施工开展创造了良好条件。
据悉，石雄铁路起自石家庄枢纽新建裕华东站，经石家庄市高新区、正定县、无极县、安国市、蠡县等地，接入京广高铁保定东站在建雄忻高铁场，并利用雄忻高铁引入雄安站。石雄铁路线路设计时速350公里每小时，由京津冀城际铁路投资有限公司建设。线路通车后，对完善京石通道现代化综合交通运输体系布局、贯彻落实京津冀协同发展国家战略、助力雄安新区建设具有重要意义。(完)
