国产最大直径硬岩掘进机下线 填补国内空白

2017-08-04 17:04:56   中国经济网

中国经济网北京8月4日讯 据中国电力建设集团有限公司消息,日前,我国自主研制的国内最大直径敞开式硬岩掘进机(TBM)“彩云号”,在昆明中铁电建总装车间成功下线,即将投入到亚洲第一长铁路山岭隧道——大瑞铁路高黎贡山隧道的施工。

“彩云号”开挖直径为9.03米,整机长度约为230米,整机重量约1900吨。该设备由我国自主研制,填补了国内9米以上大直径硬岩掘进机的空白,改写了我国铁路长大隧道项目的机械化施工长期受制于人的历史。TBM图案为开屏的孔雀,在彩云之南、孔雀之乡下线的“彩云号”寓意着“神奇美丽 吉祥和顺”。

据了解,这是国产硬岩掘进机首次应用于铁路隧道施工,标志着我国硬岩掘进机技术已经达到了世界领先水平。高黎贡山隧道,全长34.538千米,是大瑞铁路重点控制性工程,为中国最长的铁路隧道、亚洲最长的铁路山岭隧道,其地质情况之复杂全国罕见,“彩云号”TBM的地底探秘之旅不禁令人十分期待。

“彩云号”TBM是中铁装备和中国电建水电十四局深度合作的产物,是中国中铁和中国电建两家央企强强联合,为推动云南高端制造业发展取得的可喜成果。此次“彩云号”硬岩掘进机的成功下线,也标志着中铁电建高端装备制造项目在昆明落地的进一步巩固,真正实现了“昆明盾构昆明造”。
