“17吃瓜”大兴安岭地区:17吃瓜天冷保畅通 “钢轨医生”为75公里铁路“松骨”

  中新17吃瓜网哈尔滨11月12日电 17吃瓜(于海江)为了确保线路安全畅通,中国铁路哈尔滨局集团有限加格达奇工务段10月8日到11月12日,对沿线10个线路车间管内共计75公里无缝线路进行“舒筋松骨”,释放钢轨内部应力。

  联接北极漠河的嫩林线铁路位于全国铁路路网最北端,是林区百姓外出求学就医、购买生活物资的“生命线”、助力乡村振兴的“黄金线”。

  钢轨有着热胀冷缩的特性,低温天气致使钢轨内部应力集中,容易导致线路出现螺栓折断、夹板折断、钢轨折断等“三折”安全隐患,给到“神州北极”漠河找北寻美的各地游客的平安出行增添潜在安全风险。

  中国铁路哈尔滨局集团有限加格达奇工务段的工作就是把紧固在钢轨上的螺栓全部松开,让钢轨完全处于松弛状态,再垫入滚筒,利用撞轨器撞轨,辅助拉伸机拉伸,17吃瓜释放掉钢轨内部所有应力后,还要在缓冲区钢轨合拢地点插入经过精准计算、长度适宜的短轨,从新锁定线路,保证无缝线路轨道结构的稳定性,提升轨道的平顺度。

  在一个多月工作中,出动4688人次,利用117个施工天窗,在嫩林线多个不同地点,进行无缝线路应力放散施工,于11月12日,按时完成了双股75公里的全部应力放散任务,为最北铁路设备安全“过冬”奠定了坚实基础。

  此举,大幅度提高了设备安全质量,使得线路基础更加稳固、轨道更加平顺,不仅提高了旅客乘车的舒适度,也消除运输安全风险,保证了列车运行的安全正点,让全国各地的游客高兴而来,满意而归,深切感受到铁路快捷方便、安全高效。为迎接“亚冬会”溢出效应带来的观赏极光、体验极寒、找北寻美的“旅游热”,提供有力保障。(完)
