Sudden Stops In Micro Tunneling
Causes Of Unplanned Stops
Running a micro tunneling project is not easy. You can face sudden stops for many reasons. The ground can change quickly. Sometimes the tunnel face is not stable. Water can get into the tunnel and cause problems. These things make the tunnel stop without warning. Stoppage frequency goes up when this happens. In cities, there are strict rules about ground movement. This makes the risk even higher. If the ground moves, you must stop work to keep buildings safe.
CEGC’s tunnel boring machine and microtunnelling machine help with these risks. Their face pressure control keeps the tunnel steady. Ground protection systems also help keep things safe. The table below shows the main reasons for unplanned stops in micro tunneling:
|
Cause of Separation Overload |
Description |
|---|---|
|
Torque Overload |
The micro tunneling boring machine uses too much torque in tough ground. This can make the machine stop suddenly. |
|
Excessive Jacking Force |
Hard ground needs more force. This can cause overload and make stoppage frequency go up. |
|
Abnormal Slurry Flow |
Blockages in slurry flow can make solids build up. This leads to unplanned stops. |
|
Ground Instability |
Uneven pressure on the cutter head can make the machine stop. This affects how well it works. |
Here is another table. It shows how ground settlement, face instability, and water getting in can cause more stops:
|
Factor |
Contribution to TBM Stoppages |
|---|---|
|
Urban Settlement Limits |
Buildings that are not stable can make sudden stops happen if not managed. |
|
Face Instability |
Hard digging conditions can cause unplanned stops. |
|
Water Ingress |
Flooding can make you stop work to stay safe. |
Impact On Project Performance
Unplanned stops in micro tunneling hurt your project in many ways. Delays can happen and costs can go up. When the tunnel machine stops, you lose time. You also face more risk and do not know what will happen next. Stoppage frequency gets higher and finishing on time is harder. You must handle these risks to keep your project moving.
-
Unplanned stops can happen because tunnel conditions change.
-
These changes can make the tunnel boring machine stop working.
-
Project timelines can get longer and costs can increase.
-
Stoppage frequency makes planning and risk management harder.
CEGC’s microtunnelling machine solutions help lower sudden stops and make things more reliable. You get better control over unplanned stops and keep your project going.
Micro Tunneling Overload Tuning And Thrust Tuning
Overload Tuning Mechanism
Overload tuning helps your tunnel boring machine work well. It lets you manage separation overload and stop unplanned stops. You use overload tuning to balance thrust and torque. This balance keeps the cutterhead straight and lowers jamming risk. You push evenly against tunnel walls for safe digging. Matching thrust force with cutterhead speed and ground type helps you avoid restart problems and separation overload.
You control hydraulic power and change pressure with micro tunneling drives. The hydraulic system gives strong performance and reliability. You can make a strong cutting force and control how fast you dig. Variable displacement pumps let you change pressure and flow rates as soil changes. These real-time changes protect your tunnel boring machine and micro tunneling drives from separation overload.
Real-time monitoring systems help prevent overload. You get feedback on thrust, torque, and soil conditions. This feedback lets you make quick changes and stop unplanned stops. You can use automatic torque changes for tough ground. Real-time feedback helps you keep separation overload under control.
Thrust Tuning For Continuous Operation
Micro tunneling thrust tuning keeps your tunneling moving without stops. You use thrust tuning to match force with ground type. This tuning helps you avoid separation overload and stop unplanned stops. Thrust balance keeps the cutterhead moving forward. You get steady progress and fewer stops.
Micro tunneling thrust tuning works with closed-mode face support. You control support pressure at the excavation face. This control keeps ground stable and stops soil loss. You avoid separation overload and keep your micro tunneling drives working. Proper support pressure keeps ground deformation in the elastic range. The soil recovers, and you get reliable operation.
You can change pressure range, sealing, and drive torque reserve. These options help you handle different ground conditions. You use micro tunneling thrust tuning to keep your tunnel boring machine and microtunnelling machine running. You get fewer stops and better project results.
