从世界最长高速公路隧道--新疆天山胜利隧道出口端出来消息,5月24日,该隧道TBM服务隧道创下了单日进尺30.15米的新纪录。
天山胜利隧道全长22.11公里,采用“三洞+四竖井”方案。利用TBM快速掘进的优势,开辟主洞的辅助工作面,实现长隧超短打,该技术为国内高速公路隧道施工首次应用,单洞高峰期可实现3个工作面同时施工。

今年开工以来,天山胜利隧道出口端WYTJ-06标段项目经理部紧紧围绕TBM为中心组织施工生产,过程中不断优化施工工艺、强化技术攻关,在施工过程中加强超前地质预报,确保安全快速掘进。截至5月24日,TBM服务隧道累计进尺2605.05米,月均进尺达到了350米以上,并创造了月进尺500.2米的施工记录。
