CASE STUDY - When Theodolite Meets the Pipe Jacking
Pipe jacking, generally referred to in the smaller diameters as micro-tunnel, is a technique for installing underground pipelines and culverts. This method provides a flexible, structural, finished pipeline as the tunnel is excavated.
When pushing the specially designed pipes through the ground behind a shield, NT-02D offers an accurate control line of laser to avoid the deviation of center axis and elevation in a straight line.

Extreme Long-range Laser
Pinpoint laser pointer provide long-range and reliable aiming in the pipe jacking constructions, for the micro-tunnels, pipelines and culverts, etc.


External Power Supply for Full-Days' Work
NT-02D supports the external power supply for any full-days’ work, (24) which eliminates the need for recharging or carrying extra batteries.
