劳宾Ⅱ水电站引水隧洞全线贯通
Lao Biang II Hydropower Station Water Conveyance Tunnel Fully Breaks Through
2026年1月30日，公司承建的印度尼西亚劳宾Ⅱ水电站关键控制性工程——引水隧洞实现安全顺利贯通。标志着公司在海外复杂地质条件下隧洞施工能力取得重大进展。
On January 30, 2026, the water conveyance tunnel— a key controlling component of the Lao Biang II Hydropower Station in Indonesia, undertaken by the company—was safely and successfully completed. This milestone marks a major advancement in the company’s tunnel construction capabilities under complex geological conditions in overseas projects.
本工程引水隧洞全长（含支洞）2942.37米，开挖断面14.81~16.47㎡，先后穿越岩石层、土层及断层破碎带等多种复杂地质区段。面对地质条件多变、传统施工方法难以兼顾高效、安全与环保的复合需求，项目团队创新采用针对性机械化施工方案，实现了不同地质区段的精准高效施工，在技术层面取得重要突破。
The water conveyance tunnel has a total length of 2,942.37 meters (including adits), with an excavation cross-section ranging from 14.81 to 16.47 square meters. During construction, it passed through multiple complex geological sections, including rock strata, soil layers, and fault fracture zones. Faced with highly variable geological conditions and the challenge of balancing efficiency, safety, and environmental protection using traditional construction methods, the project team innovatively adopted targeted mechanized construction solutions. This enabled precise and efficient excavation across different geological sections, achieving significant technical breakthroughs.
在建设用地交付延迟六个月的被动局面下，项目团队通过科学统筹与精细管理，不仅确保了工程按期推进，更在施工效率、工程质量、成本控制及综合工期方面取得了系统性成果，圆满完成了全部开挖任务。
Despite a six-month delay in the handover of construction land, the project team, through scientific planning and meticulous management, not only ensured that the project progressed on schedule but also achieved systematic results in construction efficiency, engineering quality, cost control, and overall project duration, successfully completing all excavation works.
项目在实施过程中取得了单个工作面单月最高进尺349.0米卓越成绩，创公司历史单月进尺最高纪录，月均进尺稳定在200.3米的突出成果。
During implementation, the project achieved an outstanding single-face monthly advance of 349.0 meters, setting a new historical record for the company’s highest monthly advance. The average monthly advance was stably maintained at 200.3 meters, reflecting remarkable overall performance.
此次引水隧洞的顺利贯通，是公司深化国际工程技术合作的重要成果，展现了公司过硬的项目执行力和技术整合能力。公司将持续推动技术创新与管理升级，将成功经验转化为未来发展的新动力，致力于为全球客户提供更优质的工程建设服务。
The successful breakthrough of the water conveyance tunnel represents an important achievement in the company’s efforts to deepen international engineering and technical cooperation, showcasing its strong project execution capabilities and technical integration strength. The company will continue to promote technological innovation and management upgrades, transforming successful experience into new momentum for future development, and remains committed to providing higher-quality engineering construction services to clients worldwide.
