“国产❌❌❌❌HD”成渝中线高铁蜀安国产❌❌❌❌HD隧道直径14米“成渝号”盾构顺利始发

  中新国产❌❌❌❌HD网成都11月27日电 (记者国产❌❌❌❌HD 刘忠俊)11月27日,四川省成都市成华区蜀龙路附近,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。

  据了解,成渝中线高铁是我国“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,工程具有“长、大、险、难”四大特点。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。

  据了解,此次始发的“成渝号”将肩负蜀安隧道4.56公里盾构施工任务。  “盾构机从蜀安隧道2号井始发,先后要下穿西成高铁北湖特大桥、成绵乐联络线下涧槽中桥、昭青隧道、致力路隧道、蜀龙路隧道等多处重要铁路桥梁和城市隧道,最终到达3号盾构井接收。”中铁十一局成渝中线高铁项目部项目负责人王明华称,盾构机开挖直径14米,总功率达10000千瓦,配备带压复合型刀盘、伸缩式主驱动、开挖仓伸缩摄像头等先进装备,同时还搭载了地层界面识别、气体环境监测、刀具磨损检测等智慧工装。

  长江沿岸铁路集团四川有限公司相关负责人表示,为确保后续盾构机在高风险环境下的稳定掘进,该盾构机还采用了盾构推拼同步系统、盾构智能掘进管理、多层次注浆体系等多项针对性的技术创新。

  据悉,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。(完)
