UEA Trenchless has completed a pilot tube microtunneling project for a leading Australian retailer in Aspley, Queensland.
UEA have continued to develop flowable grouts to suit high specification trenchless installations. The latest grout design allows small annular spaces to be filled over long distances on very flat grades.
UEA Trenchless recently completed a 110 metre 450mm diameter bore using pilot tube microtunneling methods beneath the Bruce Highway at Dakabin, 26km North of Brisbane in Queensland. UEA worked successfully with CLM Infrastructure to deliver an innovative solution for inserting small diameter pipe on very flat grades over long distances.
UEA has completed a 120m investigative bore using horizontal directional drilling (HDD) methods at Dakabin, 26km north of Brisbane in Queensland. The horizontal investigative bore was conducted along a proposed pipe alignment passing under the Bruce Highway and adjacent creek.
UEA Trenchless recently completed a 600mm utility tunneling project for Bolte Civil through environmentally sensitive wetlands on the Tomago to Raymond Terrace sewer rising main. The tunneling project consisted of three road crossings, including a 110m crossing of the Pacific Highway and adjacent wetlands as part of a package of under bores in the Newcastle area. Ground conditions presented hard packed sand through to saturated muds with a high water table.
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.
