近日,深圳市白石岭区域天然气管线调整工程关键控制性工程——白石岭隧道顺利贯通,标志着我国长输管道TBM隧道实现“0”到“1”的飞跃,填补了长输管道行业TBM隧道空白。
深圳市白石岭区域天然气管线调整工程线路总长6.35千米,白石岭隧道作为其“咽喉”工程,长约6.1千米,是我国目前长输管道专用隧道施工周边环境最复杂、距离最长、单根管道断面最大的首座TBM(Tunnel Boring Machine)隧道。
白石岭隧道自2023年9月TBM始发以来,由于地理位置所限,需穿越城市公园和8处不同断层破碎带,且临近高铁、地铁、水库、高压铁塔等,给项目设计及施工带来巨大挑战。在施工过程中,各参建单位精密配合,经过9个多月努力,高质量实现了白石岭隧道贯通,实现了长输管道行业TBM隧道由“0”到“1”的飞跃。
