Microtunneling Positioning in Urban Tunneling Projects
What is Microtunneling?
Microtunneling is used when tunnels need to be built in crowded places. It is a trenchless method for sewer construction. The machine is controlled from outside the tunnel. No operator needs to go inside. This makes it good for small tunnels in busy cities. Microtunneling starts from a pit. Laser guidance systems help steer the machine very accurately. The excavation face gets constant support. This protects the ground and keeps utilities safe.
Let’s look at how microtunneling compares to another method:

-
Controlled excavation profile for predictable pipe installation
You also get face pressure control and ground protection systems. These features help manage ground settlement and face instability. You can work safely even if the ground changes. With these systems, you lower the risk of damaging utilities. Your project stays on schedule.
Tip: Always use laser guidance systems and real-time steering. This gives you the best precision in tunneling.
You can count on CEGC’s tunnel machines for safety, precision, and reliability. They help you succeed in city tunneling projects.
Micro Tunnel Boring Machines vs. Traditional Methods
Risks of Utility Clashes in Conventional Excavation
Traditional open-cut tunneling has many risks. These methods can damage pipes and cables. Workers may face cave-ins or accidents. There is also a chance of hitting dangerous materials. The table below shows the main risks:
|
Risk Type |
Description |
|---|---|
|
Utility Interference |
Risk of damaging existing utilities or infrastructure during excavation. |
|
Safety Concerns |
Risks to worker safety including cave-ins, equipment accidents, and exposure to hazardous materials. |
|
Environmental Impact |
Potential disruption to natural habitats, increased erosion, and soil and water contamination. |
Open-cut methods can cause big problems in cities. You might break important pipes or wires. Sometimes, accidents happen and people get hurt. These risks make microtunneling a smarter choice for city projects.
Advantages of Micro Tunnel Boring Machines
Micro tunnel boring machines give you better control. You can steer the machine very accurately. This lowers the chance of hitting pipes or cables. Here are some important points:
-
Micro tunnel boring machines keep horizontal deviation to a maximum of 31 mm and vertical deviation to 36 mm.
-
After jacking, the final deviations are much lower than the allowed limit.
-
You can monitor the cutting face and adjust in real time.
-
Remote operation improves safety because you do not need to send workers underground.
CEGC’s tunnel machines help control ground movement. They use face pressure and ground protection systems. Guidance systems help keep the tunnel straight. These features make microtunneling safe and reliable.
