CEGC delivers tunnel machine solutions tailored to your project requirements, ensuring your equipment stays protected and efficient.

Common issues include cutterhead wear and ground instability.

Type of Wear/Challenge

Description

Mushrooming

Cutter edge bends under heavy load, often due to overloads.

Chipping

Steel ring cracks from sudden, hard impacts.

Key Takeaways

  • Overload protection stops your TBM machine from getting damaged. This helps you avoid expensive repairs and lost work time.

  • Checking and taking care of your TBM often can find problems early. This keeps the machine working well and lowers repair costs.

  • CEGC can make special overload protection for your project. This makes your machine safer and work better.

Overload protection in TBM machines

What is overload protection?

Overload protection keeps your tunnel boring machine safe during hard work. It is a system that stops your TBM from facing too much force. Too much force can break parts and cause damage. In city projects, you work near pipes and weak ground. Overload protection helps you control thrust balance. It also helps you avoid restart failures. These failures can lead to expensive repairs.

Overload protection makes sure your tunnel boring machine stays safe. It stops sudden overloads that can break parts or delay your project.

Industry standards tell you how much force your TBM can handle. Here are some important values:

Parameter

Value Range

Maximum Torque Capacity

50-70 kNm

Allowable Alignment Deviation

±1 inch tolerance

Maximum Surface Subsidence

25 mm (1 inch)

You must control thrust balance to protect the ground and pipes. Thrust limits in microtunnelling stop your TBM from pushing too hard. This keeps everything safe and prevents problems.

How overload protection works in TBM

Your TBM uses sensors to check for high loads. Real-time monitoring watches thrust balance. It alerts you if something is wrong. If your TBM faces too much force, limiters or emergency systems help. They can stop the machine or cut power. This prevents restart failures.

  • Real-time monitoring lets you see overloads before damage happens.

  • Emergency systems can shut down your TBM if thrust balance is bad.

  • Predicting jacking force helps you find problems early and avoid restart failures.

CEGC gives overload protection that meets market standards. You can ask for custom options for your project. With good overload protection, your TBM runs well and avoids costly restart failures.

Preventing major TBM machine damage

When your TBM works in hard ground, there are big risks. Overload protection helps stop damage before it starts. Sensors watch for high thrust balance in your TBM. If the force gets too strong, the system acts quickly. It shuts down the machine or lowers the power. This keeps the motor, gears, and cutterhead from breaking. You also avoid jams that can cause restart failures.

TBM machine separation upgrades help you have fewer problems. The system keeps thrust balance steady. It stops sudden overloads that can cause restart failures. Your TBM is safe from overheating and broken parts. It also stays safe from blocked muck transport. Overload protection helps stop these failures early and saves money.

Tip: Check your TBM often and do regular maintenance. This helps you find problems before they get worse. Clear blockages and reset sensors to keep your TBM working well.

CEGC gives you strong technical support. You can choose custom options for your tunnel machine. You match the system to your project needs. Torque control solutions help keep thrust balance steady. You avoid restart failures and keep your TBM safe.
