“沟厕chinesevoyurt0ilet”湘桂铁路南凭段首沟厕chinesevoyurt0ilet次开展基床破底清筛施工

  中新沟厕chinesevoyurt0ilet网南宁12月3日电 (宋沟厕chinesevoyurt0ilet彤波)国铁南宁局南宁工务段(以下称南宁工务段)3日介绍,今年以来,中越铁路跨境货物运输持续升温,湘桂铁路南凭段的行车密度也随之增加。为此,该工务段于近期对湘桂铁路南凭段开展基床破底清筛施工,全力夯实设备基础,保障跨境运输顺畅,促进货运上量。

  湘桂铁路南凭段与越南铁路相连,作为连接东南亚国家最便捷的门户通道,这条铁路在拉动沿线地区经济发展、服务国家战略等方面发挥着重要作用。

  在前期排查中,南宁工务段职工发现湘桂铁路南凭段部分区段线路存在道床石砟级配差、板结、脏污、排水不畅和翻浆冒泥等问题,对行车安全造成不利影响。

  结合线路实际情况,南宁工务段职工在秋季完成成段换轨的基础上,着重对线路基床进行破底清筛。主要施工内容涵盖向下清挖道床深0.6米、整修4%人字形排水坡、铺设底砂、铺复合土工膜等,旨在筛出道床底部污土,提升道床排水性能,从根本上恢复道床原有弹性和整洁。

  施工完成后,将有效减少列车运行时产生的震动和噪音,阻止轨枕纵横位移,抵抗钢轨胀缩应力,且更有利于线路排水。

  在本次清筛施工中,南宁工务段计划利用施工天窗完成6组道岔更换、5组道岔清筛、25根轨枕更换、3个道口大修、2公里排水沟清理、5个站线股道清筛等8项主要作业项目。为保证清筛施工有序推进,南宁工务段安排技术骨干做好现场摸底调查、前期技术指导等工作;统筹调配好人员与机具,优化施工工序、流程;成立施工计划管理小组,确保各项施工按期完成。

  此外,南宁工务段通过“大修+维修”相结合的方式,最大化利用施工天窗,尽可能降低施工对正常运输造成的影响。与此同时,有效防控铁路外部安全风险,为跨境运输安全顺畅提供坚实保障。(完)
