Mini TBM Pipe Jacking
LIMITED SPACE
UNLIMITED POSSIBILITIES
Mini tunnel boring machines (MTBMs), often called micro tunneling machines, are small, remotely operated excavators. Our company offers machines with diameters typically between 550-850 millimeters. These machines are very handy in urban areas, the workspace required is generally smaller than that of conventional methods.
Mini tunnel boring machines (Mini TBM / Micro TBM) are specially designed for tight spaces, mainly used for laying underground utilites like water pipes, sewage pipes, and cables, or for short-distance tunnels. Their key features include: Minimal surface disruption: Using trenchless technology, they don’t require large-scale digging, avoiding interference with traffic and daily activities. Super mobile: Lightweight and compact, they’re easy to assemble and operate in very small-diameter spaces. Highly adaptable: The drill heads can be swapped depending on the soil, handling soft soil, hard rock, or mixed layers. High precision: With a great guidance system, they ensure pipelines advance accurately along the planned route.
Mini TBM Features
The mini tunnel boring machine (Mini TBM / Micro TBM, abbreviated as MTBM) is mainly used for installing underground pipelines, sewers, power lines, and telecom ducts in tight spaces in cities. Compared to traditional large TBMs, its main features are smaller diameter, fully remote operation, and it often uses the pipe jacking method for construction.

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.
