芜湖青弋江分洪道工程需改建芜铜铁路线路4.501 km,其中2.599 km为特大桥工程。为保证特大桥预制梁及长轨条运输,施工中采用正线插入无尖轨道岔方案,在既有线与工程线之间进行临时拨移衔接,此方案的运用确保了运梁、铺架施工,缩短了封锁时间,减少了大量的通信、信号设施设备投入及运输组织作业人员,满足了工期要求,确保了既有线运营安全,方法简便易行,对以后类似工程具有借鉴意义。
Wuhu Qingyi River flood diversion project to be reconstructed Wuhu Railway 4.501 km, of which 2.599 km for the bridge project. In order to ensure the transportation of prefabricated beams and long rails of the super large bridge, the project of inserting the non-sharp rail turnout with the positive line in the construction and temporarily shifting the connection between the existing and the project lines, the application of this scheme ensures that the girders are transported and laid , Shorten the blockade time, reduce a large number of communications, signaling facilities and equipment input and transport organization operators to meet the construction period requirements to ensure the safety of existing lines of operation, the method is simple and easy, with reference for similar projects in the future.
