“jl zzz 56”成渝中线高铁蜀jl zzz 56安隧道直径14米“成渝号”盾构顺利始发

  11月2jl zzz 567日,四川省成都市成华区蜀龙路jl zzz 56附近,直径14米的“成渝号”大盾构在38米深的蜀安隧道2号盾构井缓缓启动始发,标志着成渝中线高铁进入盾构施工阶段。

  成渝中线高铁是中国“八纵八横”高铁网沿江通道重要组成部分,线路自重庆枢纽重庆北站起,向西经重庆市渝北区、沙坪坝区、璧山区、铜梁区、大足区,四川省资阳市、成都市,引入成都枢纽成都站,正线全长292公里,设计时速350公里。

  蜀安隧道长约10380米,采用“盾构法+明挖法”施工。其中,盾构段长约9824米,是目前国内掘进距离最长、直径最大的土压平衡盾构隧道。蜀安隧道由“蜀安号”和“成渝号”两台盾构分段施工,“蜀安号”已先期开始掘进施工,“成渝号”将肩负隧道4.56公里盾构施工任务。

  成渝中线高铁项目建成后,将与已建成运营的西安至成都高铁、郑州至重庆高铁和在建的西宁至成都高铁、成都至达州至万州高铁等jl zzz 56多条线路连通,成渝两地旅行时间也将进一步压缩,极大方便沿线群众出行,对助力成渝地区双城经济圈建设等具有十分重要的意义。
