“强㢨一级二级202”“粤西要道”阳强㢨一级二级202信高速板塘岭隧道右洞主体全部完工

  中新强㢨一级二级202网阳江12月23日电 (记者强㢨一级二级202 王坚)随着最后一车混凝土泵送完成,粤西重要交通道路——阳春至信宜(粤桂界)高速公路(下称“阳信高速”)板塘岭隧道右洞最后一板二衬混凝土于23日浇筑,标志着全长2278米板塘岭隧道右洞主体全部完成,为全线强㢨一级二级202如期通车奠定了坚实基础。

  阳信高速是广东省境内连接阳江市和茂名市的高速公路,线路全长约142公里,采用双向六车道高速公路标准建设,设计速度为120公里/小时。

  阳信高速建成后,将形成由粤西中部通往粤港澳大湾区中南部地区的快速通道,将大幅压缩阳春至信宜的公路通行时间,极大改善当地公路货运能力及沿线民众出行条件,对完善广东省高速路网、落实广东省委省政府“推进乡村振兴战略”等战略部署具有重要的推动作用。

  据介绍,板塘岭隧道由中铁南方投资、中铁六局承建,位于广东省高州市大坡镇,左洞全长2782米,最大埋深225米,右线全长2278米,最大埋深91.5米,隧道围岩主要为片麻状花岗岩,隧道Ⅳ、Ⅴ级围岩占比大,施工难度大、风险高,是该项目唯一一个高风险隧道,该项目通过加强设计、严格施工管控,保障了板塘岭隧道建设安全。(完)
