Micro Tunnelling

Micro Tunnelling / Pipe-Jacking

Micro-tunnelling and pipe-jacking techniques are used to install pipelines without digging open trenches. This process usually starts from a launching pit and ends at a reception pit which can be several hundred meters away.

The challenge of this trench-less technology is to maintain face support, reduce friction and transport spoil.

Functions of the slurry / lubrication fluid:

- Face support in unstable ground

- Lubrication for jacked pipes
