UEA Trenchless Purchase Pilot Tube Microtunneling Unit

UEA Trenchless has recently taken delivery of an Akkerman Guided Boring Machine (GBM) also known as a pilot tube microtunneling unit. The unit is a 240A which comprises of a single stage frame with a 48” (1,219 mm) stroke cylinder for smooth continuous advancement. When used as a standalone unit, the 240A jacking frame gives UEA the ability to install up to 610mm outside diameter (OD). It can also be used in conjunction with our existing auger boring rigs which gives UEA the capability to install up to 1080mm using this method.

UEA Uses Pilot Tube Microtunneling to Deliver Pin Point Accuracy

UEA has been installing trenchless sections of steel enveloper pipe to encase DICL water main crossings on the new Rapid Transit Light Rail System under the Gold Coast Highway in Broadbeach. Working for CLM Infrastructure, UEA used a Pilot Guided Boring Machine (GBM) to drill a laser guided pilot hole achieving on target accuracy of less than 10mm. The installation auger followed the pilot bore pushing out the 100mm pilot tube and replacing it with the 550mm steel enveloper pipe. This pilot tube microtunneling method can be used for trenchless installations up to 600mm diameter and up to 80 meters in length depending on ground conditions, and is ideal for critical on grade projects requiring a high level of accuracy.
