　　近日，中铁隧道集团公司自主研发的国内首台盾尾密封刷耐磨性测试平台投入使用，实验检测和现场实际使用表明，国产盾尾密封刷性能达到国内领先水平，而造价只有国外同类产品的三分之一。

　　盾构机是一种国际先进的隧道掘进专用工程机械，已广泛用于地铁、铁路、公路、市政、水电等隧道工程。盾尾密封是盾构形成密封式结构的关键点之一，是盾构施工尤其是水下与海底隧道施工安全的重要保证。盾尾密封失效，容易导致漏水漏浆现象,甚至导致隧道塌陷，因此密封刷的质量影响着盾构的掘进速度和效果。据了解，中铁隧道集团专用设备中心于2012年成功研制出国产版盾尾密封刷，目前年产盾尾密封刷一万个以上。

　　近年来，中铁隧道集团公司投入巨资研发盾构配套设备，成立盾构刀盘生产车间，实现盾构配套设备的国产化，努力降低盾构使用成本。依托公司成立的盾构及掘进技术国家重点实验室、河南省院士工作站等高端平台，承担起国家863计划、973等多项课题。中铁隧道集团公司是采用盾构进行地铁施工的佼佼者，参与全国20多个城市地铁建设，不仅能够生产盾构整机，还在盾构再制造方面走在前列，日前完成直径6.4米、累计掘进10千米的海瑞克S217盾构的再制造，形成了从研发、施工，到制造、再制造的完整产业链。
