Construction method for replacing small-radius curve abrasion rail on seamless track
The invention discloses a construction method for replacing a small-radius curve abrasion rail on a seamless track. The construction method comprises the following steps: 1) field investigation and preparation work; (2) two transverse return lines and one longitudinal return line are erected on the rail, buckle accessories are loosened and detached, and then a new rail bar is pulled and leaned; (3) the old rail is sawed off at the rail changing starting point position and the rail changing end point position; (4) the old rail is pulled out of the rail groove, and the new rail is installed in the rail groove; (5) after the new rail is installed in the rail groove and does not displace, starting point closure gap connection is conducted; (6) after the starting point closure gap is connected, stretching the end point closure gap; and (7) after rail changing is finished, speed limiting boards are arranged, the erected return line is dismantled, and a rail line is restored. The construction method is perfect, the technical problem that the stress state requirement is high after the steel rails are laid is solved, the operation safety of constructors can be guaranteed to the maximum extent, the line state after rail replacement is good, construction tasks can be smoothly completed, and related guidance is provided for follow-up similar construction.
本发明公开了一种无缝线路更换小半径曲线磨耗轨施工方法，包括以下步骤：1)现场调查和准备工作；2)在轨道上搭设两横一纵的回流线，松拆扣配件，然后拨靠新的轨条；3)将旧轨道在换轨起点位置和换轨终点位置锯断；4)将旧轨道拔出轨道槽，并将新的轨道安装入轨道槽内；5)在新轨道安装入轨道槽不发生位移后，进行起点龙口连接；6)当起点龙口连接好后，进行终点龙口拉伸；7)换轨结束后，进行限速牌设置，并拆除搭设的回流线，回复轨道线路。本发明提供的施工方法完善，解决钢轨铺设后存在的应力状态要求高的技术难题，能够最大程度保证施工人员的作业安全，换轨后的线路状态良好，能够顺利完成施工任务，为后续类似施工提供相关指导。
