On August 15, the “Longteng” Earth Pressure Balance (EPB) Shield Machine, custom-engineered by TANGXING for the Shanghai Longhua Drainage Storage Project LPT1.1 Section, successfully rolled off the production line at the TANGXING Trenchless Industry Park.
The project includes new stormwater interception, drainage upgrade and discharge pipelines, with a total shield tunneling length of 2,264 meters.
Designed for long-distance tunneling and tight-curve sections, the Ø3800 mm EPB shield machine has an overall length of approximately 130 meters. It features:
• Double spherical articulation for enhanced steering and posture adjustment in tight curves
• Retractable screw conveyor combined with a multi-train muck transportation system for continuous and efficient long-distance excavation
From machine structure to muck removal, “Longteng” has been engineered around the project’s specific construction conditions, demonstrating TANGXING’s capabilities in customized shield machine design, system integration and complex-ground-condition adaptation.
With “Longteng” ready for deployment, the project is moving closer to the shield tunneling stage, supporting upgrades to Shanghai’s urban drainage infrastructure and flood resilience.
