湖南造盾构机开掘澳门轻轨隧道

A Hunan-made shield tunneling machine "Haojiang Pioneer" commenced tunneling for the Macao Light Rail project in Macao SAR on May 7.

5月7日，湖南造盾构机“濠江先锋号”在澳门顺利始发，开启澳门轻轨隧道掘进。

With a total length of about 2,077 meters, the tunnel section is entirely constructed underground. The project holds high demands for precision control, geological adaptability, and risk mitigation during the tunneling process, due to multiple factors, such as dense urban architectures, limited construction space, and complicated hydrogeological conditions in the construction areas. 

该工程盾构隧道区间长约2077米，全地下敷设。受限于施工区域城市建筑密集、施工场地狭窄及水文地质条件复杂等因素，对盾构施工的精准度控制、地层适应性以及应对风险叠加等方面有很高要求。

The shield tunneling machine "Haojiang Pioneer" measures 87 meters in length and approximately 690 tonnes in weight, with an excavation diameter of 7.28 meters. It was jointly developed and manufactured by the China Railway Construction Heavy Industry Co. Ltd (CRCHI), China Civil Engineering Construction Corporation (CCECC), China Railway 16th Bureau Group Corporation Limited (CR16G), and Nam Kwong Real Estate Co., Ltd.

“濠江先锋号”整机长87米，总重约690吨，刀盘开挖直径7.28米，由铁建重工、中国土木、中铁十六局、南光置业联合打造。

"To meet the project demands, the machine is equipped with intelligent monitoring and high-precision deviation rectification systems, which enables it to analyze soil structure changes ahead in real time and accordingly adjust rotation speed and thrust," explained a person-in-charge of the project. Beyond that, the machine is equipped with advanced visual cameras in the soil chamber and automatic spraying systems, which can enhance multi-party coordination efficiency during tunneling process while minimizing impacts on surrounding environment.

“针对工程建设要求，‘濠江先锋号’配置了智能化监测、高精度纠偏等功能，可实时分析掘进前方土层结构变化，调整刀盘转速与推力。”该项目相关负责人介绍，该盾构机引入土仓可视化摄像头及自动喷洒等先进系统，提升了掘进过程中多方联动管理效率，能最大程度减轻对周边环境的影响。

Upon completion, the light rail line will connect Macao's core areas, including the Border Gate (Portas do Cerco), New Urban Zone Area A, and the Taipa Ferry Terminal. It is expected to alleviate customs clearance pressure at the Border Gate, significantly improve ground transportation efficiency, and mitigate traffic congestion in the urban area.

据了解，工程建成通车后，澳门关闸、新城A区、氹仔客运码头等核心区域将实现快速联通，有效缓解关闸口岸通关客流压力，大幅提升地面交通通行效率，改善城市交通拥堵状况。
