The project had involved a rather challenging bore, with Geotech used to show mudstone and siltstone. Moreover, as the works progressed under the railing on the roadside clays with high-level plastics were prominently present.
Slow and steady won the race with this project, according to L&D Micro Tunnelling, and it was a great achievement for the team to see the drill-head poke through to the retrieval hole.
L&D Micro Tunnelling specialise in high accuracy trenchless laser guided boring. The tunnel bore machines use a vacuum extraction system where all spoil is extracted into interceptor tanks for easy disposal.
All of the heads are hydraulically driven and guided by a high accuracy laser to achieve precision over long distances.
L&D Micro Tunnelling was initially established in 2015 and its team has a combined 20 years of experience in the sewer and water industry. The company provides free boring, sleeve boring, pipe jacking, pilot auger boring and general machine hire.
The company has worked on a variety of other pipeline and rehabilitation projects including the Merri Creek sewer relief project, HMAS Cerberus, Mt Martha sewer duplication project, and Metro tunnel early works.
With this additional success on the Surrey Hills level crossing, L&D Micro Tunnelling have marked yet another job well done with more projects sure to come.
