“尺八话的巡り动画免费看”瑞梅铁路江尺八话的巡り动画免费看西段首座超两公里长隧道贯通

  中新尺八话的巡り动画免费看网江西会昌12月6日电 (尺八话的巡り动画免费看吴鹏泉 华辛明)瑞金至梅州铁路(以下简称“瑞梅铁路”)枫树排隧道6日贯通,这是瑞梅铁路江西段贯通的首座两公里以上长的隧道。

  枫树排隧道位于江西省会昌县麻州镇境内,全长2566米。该隧道穿越断层破碎带,隧道区址地下水发育,易引发突泥涌水、围岩掉块等风险。

  据隧道承建方中铁二十五局瑞梅铁路项目部三工区负责人程阳介绍,项目部在隧道施工过程中,遇到了一处埋深小于五米的浅埋段。针对这处浅埋段,项目部根据现场地质情况,将原设计长管棚施工改为一次性40米的长管棚施工,使得隧道的贯通工期提前了30天。

  此外,铁路建设者还应用湿喷机械手、自行式隧道衬砌台车等机械化、智能化设备进行施工,克服了地面塌陷、围岩破碎等困难。

  瑞梅铁路是中国“十四五”规划纲要确定的102项重大工程项目之一,线路北起“共和国摇篮”江西省瑞金市,向南经赣州市会昌县、安远县至寻乌县,再经广东省梅州市平远县、梅江区,接入漳平至龙川铁路梅州站。

  瑞梅铁路正线全长240.29公里,设计时速160公里,为国家一级单线电气化客货共线铁路。铁路部门表示,瑞梅铁路建成通车后,将进一步完善赣粤地区铁路网,加强革命老区与粤港澳大湾区,粤东地区与中部地区间的交通联系,对促进沿线经济社会发展具有重要作用。(完)
