World's first technology successfully implemented

In the northern waters of Abu Dhabi, the 1B underwater tunnel project led by China Railway International Group and constructed by China Railway Tunnel Group is steadily advancing. The project connects Sadiat Island and Umyafina Island, adopting an advanced process system of "open excavation cofferdam backfilling" and achieving multiple key technological innovations. The most eye-catching among them is the world's first large-scale successful application of single row steel pipe pile cofferdam technology. At present, the innovative design of the cofferdam structure has been successfully completed and has maintained long-term stable operation in complex marine environments, creating a crucial waterless working surface for the subsequent dry construction of the tunnel main structure. Project manager Liu Kun introduced that the seawater inside the cofferdam has been completely drained, forming a solid and flat working platform, marking the perfect transformation of this highly challenging design scheme from drawings to engineering reality. The head of the Swiss PINI Group design team also sincerely praised it after the on-site visit, calling it a dual breakthrough in design concept and engineering execution ability.

China's infrastructure hard power is praised

The successful application of this technology has sparked strong reactions in the international engineering community. It is not only an innovation in a single construction method, but also a concentrated display of China's comprehensive infrastructure technology capabilities, precision manufacturing level, and excellent project management system. From precise installation of giant steel pipe piles, high-strength sealing and waterproofing, to stable structural control in dynamic water environments, every step demonstrates the "hardcore" strength of Chinese engineering teams in solving world-class problems. The smooth progress of this project has become a shining business card for Chinese infrastructure brands in the high-end overseas market, effectively confirming China's profound transformation from an "engineering powerhouse" to a "technological powerhouse". The on-site astonishment of foreign experts - 'unable to imagine successful application' - is the most direct affirmation of China's technological innovation and engineering reliability.

Connecting islands to empower regional development

The Abu Dhabi Undersea Tunnel project goes beyond its engineering itself and has multiple strategic implications. First of all, in terms of cooperation mode, it is a successful example of Chinese enterprises' high-level management and technology output in the joint venture mode overseas, providing a new model for international engineering cooperation under the "the Belt and Road" framework. Secondly, at the socio-economic level, after the completion of the tunnel, it will completely break through the physical barriers between the two important islands of Abu Dhabi, ensure the safe two-way navigation of the newly built permanent waterway, greatly improve the local three-dimensional transportation network, promote efficient flow of personnel and logistics, and inject lasting momentum into the tourism, commercial, and overall economic development of Abu Dhabi and the entire region. The project is scheduled to be completed by the end of 2026, and Chinese builders are pushing forward with high standards and high quality. Finally, the project vividly interprets the core connotation of the "the Belt and Road" initiative, which is another landmark achievement of China's efforts to help partner countries modernize infrastructure and achieve common development through practical cooperation and technology sharing.
