Sunward’s TBM Technology Empowers Fangbai Intercity Railway Project
Project Overview
The Fangcun – Baiyun Airport Intercity Railway (Fangbai Intercity) is a vital transportation link in the Greater Bay Area, connecting downtown Guangzhou to the International Airport. Sunward’s high-quality TBM equipment has provided strong support for the “Civil Engineering Section 7,” which was recently recognized by Guangzhou Metro Group for its outstanding performance.
Targeted Engineering Solutions
The project faced unprecedented challenges, including small-radius curves and steep slopes, often described as tunneling in “Water Tofu” (extremely soft geological environments). To overcome this, Sunward’s R&D team developed:
- Shuttle-type Shield: A unique structure with a large front and small rear to ensure sufficient swing space during tight turns.
- Optimized Geometry: Shortened main engine length and increased excavation diameter to maintain stability even after tool wear.
- Intelligent Systems: Equipped with advanced geological radar, water drilling, and pre-treatment systems for 24-hour safety monitoring.
Risk Management & Safety
Tunneling through dense building groups posed a “group-level risk” of settlement. In collaboration with China Construction Fourth Engineering Division, Sunward implemented a rigorous 24-hour shift system combined with automatic monitoring and karst cave reinforcement, ensuring zero damage to urban infrastructure.
Building the Future of the Greater Bay Area
Sunward’s commitment to R&D and premium service ensures high-quality completion for global infrastructure.
