Double Shield Launch! Sunward’s TBMs Power Two Major Shenzhen Rail Projects Simultaneously
📍 Shenzhen, Greater Bay Area
01 Empowering the Greater Bay Area Rail Transit
On July 1, 2025, Sunward’s technical team achieved a “Double Launch” in the Shenzhen region. Two customized Earth Pressure Balance (EPB) shield machines were officially deployed for the Shenhui Intercity Railway and Shenzhen Metro Line 13, reinforcing Sunward’s core position in the development of the Greater Bay Area’s rail network.
Shenhui Intercity (Section 2): Conquering Karst Geology
TBM: Sunward No. 71 (EPB Shield)
Operating in the section from Longcheng Station to Pingshi Reservoir, this machine faces “mixed-face ground” and highly developed karst caves.
- Advanced Detection: Equipped with real-time karst cave detection to prevent sinkholes.
- High Torque Output: Optimized for hard-rock and complex interfaces.
Metro Line 13: Precision Settlement Control
TBM: Sunward No. 25 (EPB Shield)
Tasked with the Gongming North to Gongming Depot section, the project requires “zero-disturbance” construction under high-density residential areas and river crossings.
- Settlement Control: Precise pressure management to protect urban infrastructure.
- Digital Monitoring: Real-time data platform for stable river-crossing tunneling.
Technical synergy: Sunward’s capacity to deliver multiple high-end TBMs simultaneously.
02 Innovation Driving Global Progress
The dual launch is a testament to Sunward’s proactive “Technical Leading” strategy. By utilizing big data and AI-enabled platforms, Sunward ensures that underground spaces are developed safely, efficiently, and intelligently.
