Mini TBM Pipe Jacking
Mini Tunnel Boring Machines (Mini TBMs / Micro TBMs) are automated trenchless excavation systems specially engineered for confined space and underground utility installations. With machine diameters typically ranging from 550mm to 850mm, they are primarily used to lay underground infrastructure such as water mains, sewage pipes, and power cables.
ONE WIN ENGINEERING LIMITED utilizes advanced MTBM pipe jacking technology. The compact cutterhead and shield are assembled in a launch pit, then pushed through the ground using powerful hydraulic jacks along with the pipeline. Excavitons from the cutterhead are continuously removed, allowing seamless, long-distance pipe installation without digging surface trenches.

Applications of MTBM Pipe Jacking✅️
- Municipal Sewage and Stormwater Drainage Systems: Performing precision laying of medium-diameter gravity-flow drainage pipelines.
- Main Water Supply Trunk Mains: Laying underground water supply pipelines beneath traffic arteries.
- High-Voltage Cable and Telecommunications Conduits: Providing protective casing installation for urban power grids and fiber optic infrastructure.
- Crossing beneath Busy Roads and Railway Tracks: Executing cross-pipeline installation without road closure or damage to ground surface structures.
- Pipeline Renewal in Densely Populated Areas and Narrow Streets: Advancing projects efficiently within space-constrained urban environments.
MTBM Pipe Jacking FAQs❓️
Is a Mini Tunnel Boring Machine (MTBM) suitable for handling rock formations?
Yes, absolutely. Our MTBM systems feature high adaptability with swappable cutterheads specifically designed for various geologies, including soft soils, weathered rock, or hard granite.
Compared with traditional open-trench excavation, what are the main advantages of the MTBM pipe-jacking method?
Traditional open-trench methods require heavy road closures and bulk digging. MTBM is a trenchless method requiring only launch and reception pits, keeping surface traffic moving smoothly while reducing excavation waste and total project time.
What pipe diameters can be installed using MTBM?
Our Mini TBM units are specifically built for medium-diameter pipelines ranging from 550mm to 850mm, ideal for municipal water, sewer, and power conduits.
