Pilot Tube Microtunnelling also known as Guided Auger Boring is the process of installing service pipes underground using a pipe jacking technique in combination with a laser guided theodolite which guides the pipe to the target shaft, this method is extremely precise with deviations from target less than +/- 20mm over 70 metres.
It is an ideal trenchless technology method for the installation of gravity sewer and drainage systems which require precise line and grade.
These machines are designed to fit in the tightest areas requiring a bore pit area of only 2.4 diametre.
This process is cost effective and avoids the need to have long stretches of open cut trenches which is a hazard to the environment and also the community.
Service Pipe Installed
Gravity Sewer and Drainage
Pipe Sizes
PVC 150, 225, 300 & 375mm
Steel sleeve with carrier pipe inside up to 600mm
Locations
beneath Roads, Railways, Buildings, Trees and Vegetation
Ground Conditions
Displaceable soils such as sand, soft clays, gravel and limestone pinnacles
Distance
Highly dependant on ground conditions and pipe size but generally up to 65 metres per bore
If you require a greater distance than 65 metres contact Leon to discuss as we may be able to achieve this through various methods depending on the site conditions.
