開挖直徑為4.48米的盾構機“雙精一號”近日在鐵建重工長沙第二產(chǎn)業(yè)園下線,，將用于所羅門群島蒂娜水電站引水隧洞建設，這是國產(chǎn)盾構機首次出口所羅門群島,。

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.

針對工程難點,，研制團隊采取了一系列針對性設計，使盾構機具備了強勁的地質(zhì)適應性能,。

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.

蒂娜水電站位于所羅門群島瓜達爾卡納爾省馬蘭戈區(qū),，是所羅門群島在建規(guī)模最大的水電站工程。作為所羅門群島標志性基礎設施項目,，蒂娜水電站在竣工后可滿足首都霍尼亞拉68%的電力需求,，惠及超10萬民眾，促進當?shù)亟?jīng)濟社會發(fā)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.
