标题：京津冀地区最大高铁盾构隧道开始掘进
中新社北京1月18日电（记者 刘文文）由中铁十四局承建的津潍高铁津沽海河隧道超大直径盾构机“津城一号”18日顺利始发，标志着京津冀地区开挖直径最大、掘进距离最长的高铁盾构隧道正式掘进。
据了解，津潍高铁是连接天津和潍坊的重要交通线路，而津沽海河隧道则是该线路的关键工程。该隧道的最大直径达到了3.6米，是目前京津冀地区最大的高铁盾构隧道。同时，该隧道的掘进距离也达到了约5.5公里，是京津冀地区最长的高铁盾构隧道。
“津城一号”盾构机的顺利始发，标志着津沽海河隧道的建设进入了新的阶段。据了解，该盾构机采用了先进的全自动化施工技术，能够在复杂的地质条件下稳定、高效地推进隧道的建设。
中铁十四局相关负责人表示，他们将严格按照施工计划，确保津沽海河隧道的安全、顺利建设，为京津冀地区的交通发展做出贡献。
此次津沽海河隧道超大直径盾构机的顺利始发，不仅提升了京津冀地区高铁建设的技术水平，也为今后类似工程的建设积累了宝贵的经验。

Title: The Largest High-Speed Rail Shield Tunnel in Beijing-Tianjin-Hebei Region Starts Excavation
Beijing, China, Jan. 18 (Reporter Liu Wenwen) – The super-large diameter shield machine “Jin Cheng No.1” of the Jin潍High-speed Rail Jingu Sea River Tunnel, built by China Railway Shield Group No.14 Construction Bureau, successfully started construction on Jan. 18, marking the official start of excavation for the super-large diameter, longest tunnel for high-speed rail in Beijing-Tianjin-Hebei region.
It is understood that Jin潍High-speed Rail is an important transportation route connecting Tianjin and Weifang, while Jingu Sea River Tunnel is a key project on this line. The maximum diameter of this tunnel is 3.6 meters, which is currently the largest high-speed rail shield tunnel in Beijing-Tianjin-Hebei region. At the same time, the distance of tunnel excavation also reaches about 5.5 kilometers, which is the longest high-speed rail shield tunnel in Beijing-Tianjin-Hebei region.
The smooth start of the “Jin Cheng No.1” shield machine marks a new stage in the construction of Jingu Sea River Tunnel. It is understood that this shield machine adopts advanced fully automated construction technology, which can steadily and efficiently advance the construction of the tunnel under complex geological conditions.
A representative of China Railway Shield Group No.14 Construction Bureau said that they will strictly follow the construction plan to ensure the safety and smooth construction of Jingu Sea River Tunnel and contribute to the development of transportation in Beijing-Tianjin-Hebei region.
The smooth start of the Jingu Sea River Tunnel’s super-large diameter shield machine not only improves the technical level of high-speed rail construction in Beijing-Tianjin-Hebei region but also accumulates valuable experience for the construction of similar projects in the future.
