李江龙透露，11号线此次采用的盾构机"江城先锋号"是一台全国产盾构机，设计理念贴 合长江复杂水文地质，曾成功经受住武汉地铁12号线国博中心南站至凌吴村站越江区间全断 面泥岩掘进难题的考验。面对江底复杂地质条件，项目团队汲取了数次穿越长江的经验，盾 构机刀盘采用39%的大开口率设计，同时设置喷淋口对刀盘中心、泥浆门等进行冲刷，降低 刀盘结泥和渣土滞排、堵仓概率。 1月29日，随着直径12.56米的"江城先锋号"盾构机刀盘缓缓启动，武汉地铁11号线四期 工程关键段——江国路站至国博中心北站区间（以下简称江国区间）越江隧道正式进入盾构 掘进阶段。 编辑：赖俊 "我们这支队伍是12号线国博中心南站至凌吴村站越江区间盾构施工的原班人马。"施工 方中铁隧道局越江盾构项目经理史渊介绍，项目经理、盾构机操作员等骨干成员将系统总结 过江施工经验，为11号线四期越江工程整体推进筑牢基础。 武汉地铁二级项目经理李江龙告诉记者，11号线四期江国区间长约4.26公里，是目前武 汉地铁过江隧道最长的区间。隧道设计为单洞双线，即两个方向运行的地铁列车在一个隧道 内行驶，因此盾构机刀盘的外挖直径高达12.56米，挖出来的隧道是普通地铁隧道的 ...
