“产子岛 ~ 每周怀孕生育7次”中国应用最大直产子岛 ~ 每周怀孕生育7次径单护盾TBM下线

  中新产子岛 ~ 每周怀孕生育7次社长沙12月23日电 (向一鹏产子岛 ~ 每周怀孕生育7次)一台开挖直径为12.23米的隧道掘进机(以下简称“TBM”)23日在湖南长沙下线,将应用于引江补汉工程,这是中国应用最大直径单护盾TBM。

  该设备取名“江汉云梦号”,由中国铁建重工集团与中铁隧道局集团联合打造,整机长约140米,重约3200吨,设计最小水平转弯半径600米,适应最大坡度10%,掘进长度11.77公里,是中国应用的最大直径单护盾隧道掘进机。

  引江补汉工程沿线地质条件复杂,具有埋深大、线路长、洞径大、断层多、软岩多、地应力高等特点。

  为应对本标段长距离硬岩、断层破碎带、突泥涌水、软岩大变形、有毒有害气体等多重施工挑战,研发团队创新攻关,对TBM进行刀盘刀具小间距布置、刀盘大范围扩挖、超高压脱困、主驱动防涌门、大扭矩减速机、护盾应变受力检测预警装置等针对性优化设计,还特别配置智能掘进、围岩信息采集、岩渣智能识别、数字钻机、超前探测系统等多项智能化技术,为工程智能监造提供支撑。

  引江补汉工程是南水北调后续工程首个重大项目,工程实施后将使南水北调工程和三峡工程紧密连接。(完)
