TBM Plant Delivered for South Korea Tunneling Project

GN Solids continues to support global infrastructure development with the delivery of six TBM slurry separation plants designed for slurry balance tunneling operations in South Korea. These systems are engineered to provide reliable solids control under demanding conditions, ensuring stable performance and efficient slurry treatment throughout the tunneling process.

Engineered for Slurry Balance TBM Operations

Slurry balance tunnel boring machines (TBMs) rely on consistent slurry properties to maintain face pressure and ensure safe excavation. Effective solids separation is critical to maintaining slurry quality, reducing wear on downstream equipment, and improving overall system efficiency.

The GN slurry separation plants supplied for this project are designed to process capacities of 500 m³/h and 750 m³/h, meeting the operational demands of large-scale shield tunneling applications.

Integrated Three-Stage Separation Process

Each system incorporates three core treatment modules, forming a complete and efficient slurry processing solution:

• Scalping Screen
  The first stage removes coarse solids and oversized materials from the incoming slurry. This protects downstream equipment and stabilizes the overall process.
• Desander
  The second stage targets sand-sized particles, reducing the load on finer separation equipment and improving overall separation efficiency.
• Desilter
  The final stage removes finer particles, ensuring the slurry meets the required specifications for recirculation back to the TBM.

This multi-stage configuration allows for continuous operation with consistent slurry quality, which is essential for maintaining tunneling performance and minimizing downtime.

Modular Design for Efficient Deployment

The slurry separation plants are built with a modular design, allowing for:

• Compact structural footprint
• Simplified transportation and logistics
• Fast assembly and commissioning on-site
• Ease of maintenance and future relocation if required

This modular approach is particularly beneficial for large infrastructure projects where space constraints and installation timelines are critical factors.

Built for Reliability and Performance

GN Solids designs its slurry separation systems with a focus on durability, process stability, and ease of operation. For tunneling projects, where downtime directly impacts project schedules and costs, consistent and predictable performance is essential.

These systems are engineered to:

• Maintain stable slurry properties
• Reduce equipment wear through effective solids removal
• Support continuous TBM operation
• Deliver reliable performance under varying ground conditions

Supporting South Korea’s Infrastructure Development

The deployment of these slurry separation plants will support shield tunneling projects in South Korea, contributing to efficient excavation and long-term infrastructure reliability. GN Solids continues to expand its presence in international tunneling markets by delivering practical, engineered solutions tailored to project requirements.

Conclusion

With proven design, integrated separation technology, and a modular approach to deployment, GN Solids slurry separation plants provide a reliable solution for modern tunneling operations.

GN Solids Control continues to demonstrate its global competitiveness through engineered systems that perform where it matters most.
