Guided pipe jacking


Accurate installations (3 – 5 cm) over distances up to 50-60 meters possible. This method is preferred by high accuracy borings. Auger boring is relatively quick and in many cases has lower overall costs. Ideal for gravity drainage pipes, cable ducts or accurate installations.

Principle: Using a laser guidance system and a digital camera giving real-time monitoring, a pilot bore is driven to line and level. This will be the axis line of boring. Once complete, the auger follows the pilot prior to pipe installation. At the same time the pilot tubes are pushed out into the target pit. Through the tubular pilot culms the target can be followed with the camera.

For the method is high safety, fortified start- and target shaft needed. The machine can operate from shafts as small as 2.40 meter diameter.
