Slurry Tunnel Boring Machine
Slurry TBMs ensure tunneling in heterogeneous ground with high water permeability and groundwater pressure. They are used for constructing metro systems, highway tunnels, and water diversion tunnels.
Technical Specifications
Product Overview
Advanced Slurry Tunnel Boring Machine
Engineered for high-performance excavation in heterogeneous ground conditions, this slurry TBM series provides reliable operation in areas with high water permeability and pressure. The system utilizes pressurized slurry as a support medium to balance surrounding soil and water loads, ensuring safety and stability. With versatile configurations ranging from small to mega diameters, these machines serve critical infrastructure projects including metro systems, highway tunnels, and sub-sea crossings.
