Guided auger boring            | The process of the work

Just as in reconstruction work, trenchless technologies are seeing more use when laying new pipes as well. Among the various procedures, the highest precision is obtained with guided auger boring. Its horizontal and vertical accuracy is in the millimeter range, so in addition to laying cables and pressurized pipes, it is appropriate for use with gravitational sewage and storm drain lines with 1-3 thousandths of slant, and is in fact the only method suitable for this type of work.

The portions jacked in a single step can be up to 80 meters in length. Since it can be used under groundwater or in fluidic soil, it needs no dewatering of the ground around the pipe line. The smallest dimension of the starting pit is 2.2 meters in diameter or 1.8x2 meters of a rectangular shape, ensuring the smallest possible traffic restriction or mess on the surface.

In addition to drilling under roads and railway tracks, the features mentioned above make guided auger boring appropriate for continuous laying of pipe parallel to the street. House connection can be realized by star pattern boring launching from the starting and target shafts.

The progression rate of the procedure (60 meters per 5x8 hours) is not hindered by conditions generally occurring when using open trench technology, such as the need to break up road surfaces, traffic detours, dewatering, or restoring road condition. After the pipe is jacked in, the utility shaft is completed and the surrounding few square meters of surface cover is restored the portion in question is 100% ready.

The environmental advantages of guided auger boring are obvious. Work activities cause less disturbance to life on the surface, such as to vehicle or pedestrian traffic or residents nearby, and it can be of much shorter duration.

In addition to above mentioned, and contrary to public opinion, guided auger boring can be a more cost-effective alternative procedure when compared with traditional construction technologies. Intense depth of laying, high levels of ground-water, high numbers of crossing utility lines, busy traffic, narrow working space, high value pavement all of these elements can be ignored when using guided auger boring, unlike the overall costs of open trench technology can be multiplied by these factors.
