8. Installation with steered pilot bore An interesting variant technique for the trenchless installation of new ductile cast iron pipelines was seen for the first time in 200 at the Berlin Water Exhibition [8.1]: a steered pilot bore was run to the arrival pit over a distance of approximately 70 metres using a tunnelling machine for microtunneling. As a second step, this pilot bore was upsized to a diameter of 80 millimetres by soil removal through auxiliary pipes containing an auger feeder. The third step was to withdraw the auxiliary pipes while at the same time pulling in individual ductile cast iron pipes. The accuracy which can be achieved with this variant technique is so great that even the stringent requirements of draft DWA Arbeitsblatt A 12 [8.2] for gravity pipes can be met. 8.2 A description of the technique The first step is to make the pilot bore. Starting from the launch pit, the pilot pipe is pressed through the displaceable soil to the arrival pit. An optical system, a steering head, a theodolite fitted with a CCD camera and a display are used to enable the target point to be homed in on exactly while direction and inclination are constantly monitored (Fig. 8.1).
