How It Works

The Single Shield TBM operates by pressing a disc-cutter-equipped rotating cutterhead against the tunnel face. Under immense contact force, the disc cutters chip away the rock mass, breaking it into manageable fragments.

• Rock Cutting: Disc cutters fracture the rock face under pressure exceeding 250 MPa.
• Material Removal: Buckets and chutes guide cuttings to the central muck ring, where gravity feeds them onto a conveyor system.
• Dust Control & Cooling: High-pressure water jets suppress dust and cool cutting tools.
• Material Transport: Muck is transferred via belts or haulage vehicles out of the tunnel for disposal.

This continuous cycle enables steady advance rates and efficient muck removal with minimal downtime.

Safety and Maintenance Features

• Rear-access cutter change: Disc cutters can be replaced safely from behind the cutterhead structure — no exposure to the unsupported tunnel face.
• Vibration reduction: Hydraulic stabilizers maintain smooth operation and protect components.
• Overcut design: The boring diameter exceeds the shield diameter to prevent jamming and enable flexible steering.

Precision Steering and Control

The machine incorporates fixed or displaceable drives equipped with steering cylinders, torque box systems, or longitudinal displacement cylinders, allowing operators to achieve tight curve radii and precise alignment adjustments.
The upward offset cutterhead axis further enhances guidance and prevents shield binding in uneven rock.
Overcut rollers and optional overcut housings can expand the boring diameter for custom lining requirements, while bi-directional cutterhead rotation in pipe-jacking configurations helps counteract torsional rolling.

With diameters ranging from 1.7 to 16 meters, EPB Shields are suitable for both urban infrastructure and large-scale tunnelling projects worldwide.

Key Technical Capabilities

• Geology: Soft, cohesive, and low-permeability soils (clay, silt, loam)
  
• Diameter Range: 1.7 m – 16 m
  
• Support Type: Earth pressure balance (no external medium required)
  
• Applications: Metro tunnels, sewage tunnels, utility lines, and urban crossings

How It Works

The EPB Shield utilizes the excavated soil itself as a supporting medium. The rotating cutterhead loosens and conditions the ground, while a screw conveyor regulates the pressure balance and removes the muck.

• Excavation: The cutting wheel removes material from the tunnel face.
  
• Face Support: Conditioned soil stabilizes the tunnel face, preventing collapse or surface settlement.
  
• Material Transport: The screw conveyor moves excavated material to a belt conveyor for removal.
  
• Control System: Pressure sensors and automation ensure equilibrium between face and ground pressure at all times.

This integrated system allows tunnelling to proceed safely and efficiently, even under challenging geological or hydrostatic conditions.
