UNB-40 / Directional drilling machine
This is a small-sized directional drilling unit for quick construction of pipelines, with the pulling capacity of 40 tons.
UNB-40 is a heavier and more powerful version of UNB-20. It is a pit-launched machine based on the principle of dry compaction. Increased pushing and pulling force allows installing new pipes as large as 315 mm in diameter at the distances of up to 120 m. Pipe-bursting capabilities are also increased to 315 mm.
The trenchless procedure for construction of pipelines having the diameter up to 315 mm, up to 120 m long:
- The dry method for pipe-jacking, controllable in terms of plan and profile, with no soil carried away from the working passage.
- Worn pipeline replacement.
Options for the UNB-40 unit installation and operation:
- from the pit in the box.
No bentonite mixtures required.
Soil types: up to and including the 3rd category.
- Monitoring device: Radar, RD – 385 L
