中新Welcome back. It's good to see you. Click below to log in to the rewards program at your property.社长沙12月23日电 (向一鹏Welcome back. It's good to see you. Click below to log in to the rewards program at your property.)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Welcome back. It's good to see you. Click below to log in to the rewards program at your property.，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)
