Microtunneling technology overview

Tunnel machine types and scale
There are different tunnel machines for microtunneling. The machine you pick depends on your project. Microtunneling uses remote-controlled pipe jacking to put pipes underground. No one needs to go inside the pipe, so it is safer. This technology works for pipes up to 36 inches wide. The table below shows the usual pipe sizes for each tunnel machine:
|
Machine Type |
Diameter Range (ft) |
Diameter Range (m) |
|---|---|---|
|
Small TBM |
5 ft to 20 ft |
1.5 m to 6 m |
|
Defined Small TBM (NA) |
6 ft to 12 ft |
1.8 m to 3.6 m |
|
Micro Tunnel Boring Machine |
3.3 ft to 13.1 ft |
1 m to 4 m |
Microtunneling machines fit between auger boring machines and big TBMs. You should think about pipe size and ground type to choose the best machine.
Curved tunnels and navigation
Microtunneling can make curved tunnels under streets and buildings. You can steer the machine with special guidance systems. These include Laser Total Station and Gyro Navigation. These tools help keep the tunnel in the right place. They also help you avoid things in the way. Hydraulic joints let the tunnel curve tightly, so you can go around other utilities. Real-time monitoring helps you control and change the tunnel’s path if needed.
Tip: Make sure launching and reception pits line up for good microtunneling.
Precision and safety in urban environments
Microtunneling gives you high accuracy. Guidance systems show real-time feedback to keep the tunnel straight. Hydraulic joints spread out the weight, which keeps the tunnel safe. Workers stay above ground, so there is less danger from cave-ins or falling dirt. Microtunneling also makes less noise, removes less soil, and lowers emissions. This helps keep the city cleaner. Microtunneling is good for putting in utilities, cables, and other projects where space is tight and safety matters.
Small radius lowers disruption for micro tunneling downtown

Reduced surface impact
When you use microtunneling, the city looks different. Old ways of building dig up long roads. This makes a lot of noise and dust. Streets get blocked, and people get upset. Microtunneling lets you put in pipes and cables without digging up the whole road. You only need small pits to start and finish the work. There is less noise and fewer traffic problems. Stores can stay open, and people can walk or drive like normal. Microtunneling makes less mess, so you do not have to move as much dirt. The city stays cleaner and safer while you build.
-
Microtunneling helps you put in pipes and conduits with high accuracy and little mess.
-
The technology works well in busy cities where you do not want to bother people.
-
You can use microtunneling for subway lines and utility conduits, which keeps traffic moving.
Avoiding existing infrastructure
Microtunneling helps you avoid hitting things already under the street. Cities have lots of pipes, cables, and building parts underground. With microtunneling, you can steer the machine around these things. Special guidance tools let you make sharp turns and pick the best path. You do not have to worry about breaking water pipes or gas lines. This means fewer accidents and less chance of service stopping. You can also use smaller wells, so you dig less and are less likely to hit something important.
-
Microtunneling works well in cities where there are many things underground.
-
The method lets you work safely near other pipes and cables without breaking them.
-
You can put in new pipes even when there is not much space underground.
CEGC helps you pick the right tunnel machine. They give advice based on your city’s ground and what your project needs. This makes your work faster and lowers the chance of problems in busy city areas.
Faster timelines and minimized restoration
Microtunneling makes your project go faster and means you fix less. The work sites are small and tidy. You do not have to close big parts of the road or sidewalk. This means you finish sooner and people can get back to normal life. The method costs less because you do not have to fix as much road or grass. You save money and time, and people complain less.
-
Microtunneling can be done in cities without bothering businesses and traffic much.
-
The small work sites let people keep living their lives, which saves money.
-
Trenchless methods like microtunneling usually cost less than digging big trenches.
-
You can put in or fix more pipes each year, so your projects cost less.
-
Microtunneling causes less trouble for cars and people, which means fewer complaints.
-
The method keeps stores open, so the city does not lose tax money.
-
Microtunneling makes the city safer and helps the environment, which saves money later.
-
Projects finish faster because microtunneling takes less time than old ways.
-
The process does not mess up the surface as much, so it costs less to fix.

FAQ
Can an auger boring machine replace a Microtunnelling Machine for wastewater projects?
A Microtunnelling Machine is better for wastewater pipes in cities. It is more accurate. It also helps you miss other pipes and cables underground.
At what project size does a TBM tunnel boring machine become more economical?
A TBM tunnel boring machine is good for long tunnels. Pick this machine if your tunnel is several hundred meters or longer.
Does CEGC offer a combined auger boring machine and Microtunnelling Machine package?
You can ask CEGC for both machines in one package. This lets you work with different ground types and project needs.
