Key TBM Tunnel Clogging Indicators
Cutterhead Torque Monitoring
You should check cutterhead torque every day. This helps stop cutterhead clogging and keeps the tunnel stable. Cutterhead torque tells you how hard the tunnel boring machine works. High torque means clogging might happen, especially if clay minerals are over 10%. If torque goes above 2800 kN·m, look for cutterhead clogging and hot spots. These problems can slow tunnel progress and lower performance.
CEGC’s wear management system lets you watch torque and cutterhead temperature live. It warns you early about clogging and cutterhead wear. You can use the online monitoring system to get data and change operations fast. Watching torque and temperature helps keep the tunnel stable and makes performance easier to predict.
Tip: Make daily logs for torque and cutterhead temperature. Check these logs with your team to find patterns and act before clogging slows the tunnel.
Muck Flow Rate Tracking
Muck flow rate shows how well the tunnel boring machine removes dirt. If muck flow drops, cutterhead clogging or bad ground may happen. Steady muck flow keeps the tunnel stable and helps predict daily progress. You should use sensors and the online monitoring system to watch muck flow. This helps you spot clogging and keep tunnel performance strong.
CEGC’s soil conditioning and muck transport solutions help muck move easily. These solutions lower clogging risk and keep the tunnel stable. You can check muck flow and cutterhead temperature in real-time. If you see changes, adjust the system to stop downtime and keep tunnel boring machine performance steady.
-
Check muck flow rate every shift.
-
Compare flow with cutterhead torque and temperature.
-
Use the online monitoring system for clogging alerts.
Slurry and Face Pressure
Slurry and face pressure are important for tunnel stability and cutterhead performance. Keep pressure between 120 and 280 kPa to stop ground loss and cutterhead clogging. Sudden pressure spikes can cause fast clogging and hurt tunnel stability. Regular checks help you predict daily progress and performance.
Field data shows pressure spikes in the excavation chamber happen before operators can react. These spikes raise clogging risk and can cause slurry loss at the surface. Use real-time monitoring and the online monitoring system to watch pressure changes. CEGC’s face pressure control system keeps pressure steady and stops clogging.

Advance Rate and Settlement
Advance rate and settlement show how fast the tunnel boring machine moves and how the ground reacts. Low advance rates can mean cutterhead clogging or bad ground. High settlement means tunnel stability or face stability is lost. You should check advance rate and settlement every day to keep tunnel performance and predictability high.
CEGC’s guidance and alignment solutions help you watch advance rate and settlement. The online monitoring system collects data on tunnel movement and cutterhead temperature. You can use this data to change operations and stop clogging.
