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。
