What Services Included In Micro Tunneling
Rakaz Plus brings two decades of experience, advanced technologies, and a highly skilled team to micro tunneling projects. We completed our first micro tunnel project in India, and have since built up a micro tunnel team that is second to none. This team has installed over 100,000+ lineal feat of micro tunnel to date.
Rakaz Plus operates multiple micro tunneling equipment spreads, including a pilot tube micro tunnel system to carryout multiple projects throughout North America simultaneously. Laser guidance, gyroscopes, tachymetry and cameras help operators guide the process from the surface. Completed tunnels range in size from 24 inches to 85 inches in diameter in ground conditions that span wet sands and silts to cobbles and boulders, and even solid bedrock
We Proud What We Do
Enables accurate installation of pipes of diameters ranging from 24 inches to 120 inches. Delivers accurate results for curved and long-distance drives. Effective in soft, unstable and wet soils, bedrock, and in breaking down cobbles and boulders.
A number of types of mechanical excavation systems are available and these are similar to those employed in other forms of tunneling. Shields, excavation and face support can be provided for a wide variety of ground conditions. Construction tolerances are comparable with other tunneling methods, and the pipe jacking method generally requires less over-break than segment tunnels and provides ground support and reduces potential ground movement. The pipe jacking technique and its components have been subject to extensive and ongoing research at leading UK universities including both Oxford and Cambridge. This has included model and full scale testing of pipes and joints and the effects of lubrication and soil conditioning on the pipe jacking process.
