Capabilities At L&D Micro Tunnelling we specialize in high accuracy trenchless laser guided boring. Our TBM's use a vacuum extraction system where all spoil is sucked into interceptor tanks for easy disposal. All of our heads are hydraulically driven and guided by a high accuracy laser to achieve precision over long distances. We currently have 3 TBM's operating throughout Victoria with Drill heads ranging from 350mm - 600mm in diameter and drives of up to 120 meters. We are equipped when access to the drill shaft is limited or when setting up inside a basement. Ground Conditions Expand With any micro tunnelling project ground conditions account for almost all the risk involved when taking on a project. Geo technical reports and good job planning are essential for projects to run smoothly. We can offer all tunnelling methods through most ground types. Bore Sizes Expand We currently have Drill heads ranging from 350mm to 600mm in diameter. Pipes We Install Expand Iplex PVC RESTRAIN (threaded pipe) PVC, electrical conduit Storm pro & Sewer pro HDPE GRP Steel Casing Clay pipe Lengths Expand Two of our machines, LD1 & LD3 can bore up to 120 meters on line and on grade with a +/- 10mm tolerance in most ground conditions. Our Limited access machine (LD2) can drill up to 35 meters in most ground conditions with a +/- 10mm tolerance. This machine has a smaller footprint than LD1 & LD3 and is perfect for branch sewers, city lane ways and small road crossings. Setup Expand LD1 & LD3 Launch shaft details: 4m x 1.5m minimum LD2 (Limited access machine) Launch shaft details: 3m x 1m minimum Once all equipment arrives on site, setup of tunnelling equipment takes no more than 3 hours. In House Engineering Expand We have a fully fitted out factory with highly skilled employees which allows us to design, build, maintain and repair any equipment that needs repairing during any project. This allows us to keep the job at hand to be finished on time and on budget at every occasion. Machine Hire Expand Go to the contacts pages and call or email for more information.
