湖南日报8月23日讯(记者 曹娴 通讯员 胡清)8月22日,在吉林省中部城市引松供水工程总干线二标段,“长春号”岩石隧道掘进机(TBM)穿隧而出,标志着国产首台大直径敞开式岩石隧道掘进机,在吉林省最大规模水利工程成功贯通。
引松工程是吉林省投资规模最大、输水线路最长、受益面积最广、施工难度最高的大型跨区域引调水工程。二标段采用的大直径岩石隧道掘进机,由中国铁建重工集团、中国铁建十八局集团联合浙江大学、天津大学、中南大学等科研院校自主研制。
该项目自2011年申请国家立项后,成立了以铁建重工为首的样机研发项目组。针对引松工程“长距离、岩层不稳定、较多断裂带、围岩强度软硬交接”等地质特点和技术难点,项目组突破大直径TBM高效破岩、多系统协调控制、关键部件状态监测与诊断等核心技术,为工程量身定制施工装备。
2014年,国产首台8米级大直径敞开式TBM样机研制成功。2015年1月,TBM部件陆续运达工地,铁建重工服务团队入驻现场组装调试,当年3月开始试掘进。
国产首台大直径敞开式TBM打破了国外技术长期垄断,推动我国现代化隧道施工装备和施工技术迈向世界领先水平。掘进期间,TBM施工最高日进尺86.5米,最高月进尺1209.8米,月平均进尺661.59米,刷新国内敞开式TBM施工纪录;TBM利用率月均56.85%,最高达66.86%,施工水平达到国际领先。
