Pipe jacking: auger boring and guided auger boring
Pipe jacking is a no-dig technique used for installing utility pipes underground with minimal disruption to the surface. It is a cost effective and time saving alternative to open cut methods when installing pipes below 5 metres depth or under surface obstacles undesirable to be disturbed such as roads and railroads.
A specialized pipe jacking technique is auger boring. This age old and simple method is applicable in a wide range of ground conditions from sand, through clay to solid rock. It provides ready to be used water-tight pipelines of steel, reinforced concrete or unglazed vitrified clay.
Creating the bore for the utility pipe involves pushing a string of steel casings along the planned direction while excavation takes place by means of rotating auger flights.
Conventional auger boring provides limited steerability. Where cm accuracy is critical the specialized technique of guided auger boring is available.
Sycons Ltd. has considerable expertise in conventional auger boring and guided auger boring. We have undertaken a track record of turnkey utility pipe installations underground. Diameters from 200mm to 1400mm are achievable with single drive lengths of 100 metres depending on soil properties. Our complete range of guided boring equipment enables us to carry out full service constructions as far as 800 kilometers from Hungary installing a 40 metres length span in around 10 days.
