Assisted by pilot rods equipped with optical passage, steering head, and theodolite with CCD camera and monitor, open-guided boring can be carried out in displaceable ground. The pilot pipe is pushed through the ground towards the target shaft. The direction is monitored by the CCD camera throughout the whole process. The direction of the head is adjusted by rotating the pilot pipes to guide the steering head on the cross hair image on the guidance monitor.
The double pilot rod allows the internal rod to turn the steering head; whilst the outer steel sleeve takes all the ground friction.
The precision-guided bore made by the pilot pipe is then followed by the steel cased auger section which enlarges the bore to the same size as the product pipes.
The product pipes are then jacked through whilst the casings are being retrieved in the reception pit.
Alternatively the product pipe can be jacked directly by using an extension kit. The soil is transported through the steel pipes to the reception shaft by reversing the rotation of the augers.
