CEGC Tunnel Boring Machine (TBM) Series

CEGC's Tunnel Boring Machine (TBM) series represents cutting-edge trenchless tunneling technology, engineered to conquer the most challenging underground construction projects. As the "pearl in the crown of high-end equipment manufacturing," our TBMs seamlessly integrate mechanical, electrical, pneumatic, and hydraulic systems to deliver exceptional performance across diverse geological conditions.

Advanced Technology

Our TBM series features heavy-duty hard rock cutterheads with composite designs, capable of handling rock formations with compressive strengths up to 180 MPa. Equipped with intelligent guidance systems, real-time warning mechanisms, and remote operation control, these machines provide precise excavation management with comprehensive parameter monitoring. Innovative high-pressure sealing technology ensures safe operation in extreme water pressure environments, including underwater crossings and river tunnels.

The multi-section shield design offers superior adaptability and stability, while three-dimensional mucking systems with intelligent rail transportation ensure efficient material removal. Variable support systems, including honeycomb-type segment assembly and multi-mode filling technology, provide immediate ground stabilization across varying tunnel conditions.

Superior Performance

CEGC TBMs cover excavation diameters from 3.73m to 4.41m, with machines ranging from 53m to 95m in length and weights from 185 to 380 tons. These powerful machines excel in challenging environments including hard rock formations, medium-weathered limestone, tuff strata, deep burial depths with high water pressure, and complex river crossings. Capable of long-distance tunneling up to 8,000+ meters and inclined excavation up to 8-degree slopes, our TBMs deliver unmatched versatility.

Key Advantages

Superior safety features, exceptional operational flexibility, and high excavation efficiency define the CEGC TBM advantage. Minimal surface disturbance and environmental impact make our machines ideal for urban and environmentally sensitive projects. Applications span energy infrastructure, water resources, mining operations, and urban utility corridors.

Backed by comprehensive technical support, from pre-project analysis to real-time guidance and maintenance, CEGC TBMs have successfully completed numerous projects including heating pipelines, nuclear power infrastructure, reservoir connections, and mining roadways. Our commitment to innovation and customer success drives continuous advancement in tunneling technology, connecting communities and enabling critical infrastructure development with maximum efficiency and minimal environmental footprint.
