Breaking Underground Boundaries, Redefining Urban Lifelines

CEGC's trenchless engineering solutions represent the pinnacle of zero-excavation technology, enabling infrastructure networks to traverse beneath rivers, highways, heritage districts, and densely populated areas without a single shovel breaking ground.

From the narrow confines of DN220 utility installations to the massive 12-meter diameter metro tunnels, our comprehensive portfolio of HDD machines (GS800-LS to GS12000-TS), precision pipe jacking systems (DN220-DN2400), and customized TBM equipment delivers unmatched versatility across the complete spectrum of underground construction challenges. With thousands of successful projects completed across 60+ countries, CEGC has proven its capability to reduce construction timelines by 40%, minimize environmental disruption by up to 95%, and maintain millimeter-level accuracy even through the most challenging geological formations. 

Technical Excellence:

HDD Systems: Navigate beneath streets, rivers, and highways with steering accuracy of ±0.1°, installing pipelines up to Φ1200mm across distances exceeding 2000 meters
Pipe Jacking Solutions: Auger boring (DN220-DN600) and microtunnelling (DN400-DN2400) for urban sewer networks and utility corridors with automated guidance systems
TBM Engineering: 3-12 meter diameter customized tunnel boring machines equipped with real-time geological monitoring and adaptive cutterhead technology for metro and utility tunnel projects

Application Scenarios:

Urban Infrastructure: Water supply networks, gas distribution systems, telecommunications cables, and wastewater collection beneath city streets without traffic disruption
River & Waterway Crossings: International transmission pipelines and major utility crossings protecting aquatic ecosystems and navigation channels
Metro & Rail Systems: Large-diameter tunnels for underground transportation networks in congested metropolitan areas
Environmental Protection Zones: Installations through wetlands, nature reserves, and UNESCO heritage sites with zero surface footprint and full regulatory compliance

Proven Performance:

  • Projects like "Xishan No. 1" successfully navigated geological formations with strength variations up to 31.5 MPa, crossing both rock and silty clay layers
  • "Qingsheng No.1" slurry pressure balance shield TBM achieved 5137.5 meters total tunneling with maximum single jacking distance of 2198.9 meters
  • 24/7 operation capability with automated monitoring systems and remote diagnostics
