-
Checking and fixing things often during tunneling keeps the machine on track. This makes the project faster and safer.
Microtunnelling Yaw Control and Alignment
What Is Yaw Control?
Yaw control helps you keep your tunnel machine facing the right way. In microtunnelling, pipelines must be installed with very tight limits. Yaw control uses a guidance system, like a laser, to show where the machine is and which way it points. You get updates right away. The table below shows the main features:

Laser feedback on yaw, roll, and position |
|
Steering Mechanism |
Steering jack lets you adjust the path during tunneling |
|
Application |
Works under rivers, railroads, and tough ground |
Role in Micro Tunneling Machine Steering
Yaw control helps you steer your tunnel boring machine. It keeps the machine’s direction correct. You need to watch the machine’s attitude, including yaw, pitch, and roll. This helps you follow the design. Guidance systems, like laser targeting, help you make changes. CEGC’s systems give you reliable steering and alignment.
-
Yaw control keeps your machine moving straight.
-
You get updates fast for quick fixes.
-
Laser guidance makes accuracy better over long distances.
Alignment and Friction Connection
Good alignment in microtunnelling lowers jacking friction. If your tunnel machine goes off course, friction gets higher and jacking becomes harder. Many things affect friction, like ground type, pipe length, and how long you work. Keeping alignment with good control lowers resistance and protects your tools. CEGC’s guidance and steering systems help you avoid mistakes and keep your project running well.
How Micro Tunneling Yaw Control Lowers Jacking Friction Events

Causes of Jacking Friction
Jacking friction happens when the pipe moves through the ground. Many things can make resistance go up. Pipe deviation and ground closure cause the pipe to rub against soil. Soil properties and pipe size change how much friction you get. If the frictional coefficient is higher than 0.1–0.3 for lubricated drives, you need more jacking force. Misalignment and geology are important too. Overcut annulus, how much lubricant you use, and face resistance affect jacking loads. When the soil type changes, jacking force changes as well. You must check pipe alignment and soil conditions to keep friction low.
Mechanisms of Friction Reduction
Micro tunneling yaw control keeps the pipe on the planned path. You use guidance systems to steer the tunnel machine. Keeping the pipe straight lowers pipe-soil contact. This helps the lubricant work better. The lubricant forms a layer between the pipe and soil. You see smoother movement and less resistance. Micro tunneling yaw control stops misalignment before it starts. You get feedback right away and adjust the machine’s direction. The pipe jacking method works best when the pipe stays in line. Micro tunneling yaw control makes trenchless pipe jacking work better. You avoid sudden spikes in jacking force and protect your equipment.
Tip: Use guidance systems and yaw control to keep your pipe centered. This helps the lubricant spread evenly and lowers jacking friction.
