北京地铁九号线军事博物馆站至东钓鱼台站区间,盾构机穿越含大粒径漂石的富水层被困,通过分析盾构机各项参数和地层状况做出正确判断,各施工环节紧密配合,对刀盘刀具采取技术措施,使盾构机顺利脱困,避免了次生灾害的发生。
In the interval between Military Museum Station and East Diaoyutai Station of No.06 segment of Beijing Subway Line 9,the shield tunnel is stuck in water-rich cailloutis-erratic-boulder stratum containing large erratic boulder.After analysis on various parameters of shield machine and stratum conditions and based on practical experiences,various systematic parameters of shield machine are adjusted and special technical measures are adopted for arrangement of shield cutter head and treatment of tunnel face to successfully extricate the shield machine,providing valuable references for similar extrication of shield machine in the future.
