On February 17th, 2025, the Tunnel boring machine “Shuangjing No.1” was exported to the Solomon Islands for the first time, marking the construction of the diversion tunnel at the Tina Hydropower Station. The project, which spans approximately 3.2 kilometers, faces engineering.
Challenges such as long-distance tunneling, crossing fractured zones, and high-pressure water conditions. To address these, the development team implemented targeted designs, including a composite cutter head for hard rock strata, substantial reserves of thrust and torque, an integrated pressurized manlock, intensive back-up support, and an advanced geological prediction system.
The Tina Hydropower Station, located in the Malango region of Guadalcanal Province in the Solomon Islands, is the largest hydropower project currently under construction in the Islands. Upon completion, the Tina Hydropower Station will meet 68% of the electricity demand of the capital city Honiar, benefiting over 100,000 residents and promoting local economic and social development.
In recent years, shotcrete technology for underground rock support has seen significant advancements, particularly with the integration of digital technologies like SmartScan and other IoT-based innovations. Robbins, in-house manufacturing facility in Vadodara, India, to encourage the growing business opportunities in tunnel construction for transportation infrastructure.
China has successfully exported a Tunnel Boring Machine (TBM) to the Solomon Islands for the first time, marking a significant milestone in infrastructure collaboration between the two nations. The TBM, manufactured by a leading Chinese engineering firm, is set to play road and urban connectivity projects.
Enhancing Infrastructure in the Solomon Islands
The Solomon Islands, an archipelago in the South Pacific, has been facing infrastructure challenges due to its rugged terrain and scattered islands. With a growing need for improved transportation for enhance road connectivity and reduce travel time between key regions.
The Chinese-made TBM is expected to be used in a major road tunnel project, which will help in reducing congestion, improving access to remote areas, and fostering economic growth. Given the limited road networks and difficult landscapes, tunnel construction is seen as a game-changer for the country’s urban planning and transportation system.
China’s Growing Influence in Pacific Infrastructure
China has been expanding its infrastructure investments in the Pacific Islands, providing funding and technological expertise for roads, bridges, and public facilities. The export of the TBM highlights China’s growing presence in the construction and engineering sector of the region.
particularly in countries that are looking to modernize their infrastructure with cost-effective and efficient solutions. With this project, Chinese engineering firms have further demonstrated their ability to design and manufacture advanced TBMs that can operate in diverse geological conditions.
offering high precision, safety, and efficiency in tunnel excavation. The Solomon Islands’ government has welcomed the initiative, citing China’s technical expertise and financial assistance as key factors in accelerating national infrastructure projects.
The TBM exported to the Solomon Islands is a state-of-the-art machine, equipped with advanced tunneling technology that ensures smooth and precise excavation. Some of its notable features include.
- Automated cutting heads to deal with varying rock and soil conditions High-powered hydraulic systems for better excavation efficiency Enhanced safety mechanisms to ensure stability during tunnel boring Real-time monitoring and guidance systems for precision engineering.
The machine is expected to be deployed in a multi-kilometer tunnel project, which will significantly improve road transportation and strengthen the Solomon Islands’ infrastructure resilience against climate-related challenges.
Economic and Strategic Implications
Moreover, the partnership strengthens bilateral economic relations, paving the way for more Chinese-funded projects in the Pacific region. This move aligns with China’s Belt and Road Initiative (BRI), which aims to boost global connectivity through major infrastructure developments.
