出征！国产盾构机首登所罗门群岛

开挖直径为4.48米的盾构机“双精一号”近日在铁建重工长沙第二产业园下线，将用于所罗门群岛蒂娜水电站引水隧洞建设，这是国产盾构机首次出口所罗门群岛。

The "Shuangjing No.1" shield machine, with an excavation diameter of 4.48 meters, rolled off the production line recently at the Second Industrial Park of CRCC Heavy Industry in Changsha. It will be used for the construction of the water diversion tunnel of the Tina Hydropower Station in the Solomon Islands. This marks the first time that a Chinese-made shield machine has been exported to the Solomon Islands.

针对工程难点，研制团队采取了一系列针对性设计，使盾构机具备了强劲的地质适应性能。

In response to the engineering challenges, the R&D team adopted a series of targeted designs, enabling the shield machine to have strong geological adaptability.

蒂娜水电站位于所罗门群岛瓜达尔卡纳尔省马兰戈区，是所罗门群岛在建规模最大的水电站工程。作为所罗门群岛标志性基础设施项目，蒂娜水电站在竣工后可满足首都霍尼亚拉68%的电力需求，惠及超10万民众，促进当地经济社会发展。

The Tina Hydropower Station is located in the Marango District, Guadalcanal Province, Solomon Islands. It is the largest hydropower project under construction in the Solomon Islands. As a landmark infrastructure project in the Solomon Islands, upon completion, the Station can meet 68% of the electricity demand of the capital, Honiara, benefit over 100,000 people, and boost the local economic and social development.
