中新网重庆10月4日电 (贾楠 殷雄辉)3日,在由中铁建设集团承建的成渝中线高铁重庆科学城站,随着最后一榀贝雷架顺利拆除,国内首例“四车同步并进”跨铁路贝雷架拆除工艺成功实施,为后续同类跨铁路贝雷架拆除施工提供了宝贵经验。

成渝中线高铁重庆科学城站坐落于重庆市沙坪坝区,站房建筑面积1.93万平方米,车场规模2台6线。本次施工的站西二路桥全长117.5米,总宽51米。

“本次拆除作业工况复杂、管控难度大。由于桥下汽车吊无法进入,传统吊拆工法不适用。此外,轨道处于曲线段,且多吊点作业对拆除施工精度控制标准要求很高。”中铁建设集团成渝中线重庆段站房1标项目部负责人康宽彬介绍。

据悉,此次拆除作业施工区域横跨既有铁路线路,常规吊拆方案不具备实施条件。为破解拆除难题,项目团队创新采用“液压提升落梁+台车平移转运+场外逐组吊拆”三步工法,首创四车同步并进控制技术。该工法对提质增效、零干扰施工具有明显效果。单组贝雷架从拆除到运出仅需约1小时,8组循环核心拆除工序仅占用线路3天,较传统方案节省工期约28天。

长江沿岸铁路集团重庆有限公司大足指挥部指挥长黄成华表示,目前,重庆科学城站跨线区域大跨度贝雷架拆除施工已全部完成,项目进入装饰装修收尾和收官冲刺阶段,预计10月底达到全面亮相条件,建成通车后将大幅缩短重庆与成都的时空距离,加速两地“1小时通勤圈”的形成。
