“男生的坤坤㩙进老师的句号作文”瑞梅铁路江男生的坤坤㩙进老师的句号作文西段首座超两公里长隧道贯通

  中新男生的坤坤㩙进老师的句号作文网江西会昌12月6日电 (吴男生的坤坤㩙进老师的句号作文鹏泉 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,加强革命老男生的坤坤㩙进老师的句号作文区与粤港澳大湾区,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)
