    Micro Tunnel Boring Machine (MTBM)

    Micro Tunnel Boring Machine (MTBM)

    Cutting-Edge Tunneling – Small but Mighty, Infinite Possibilities!

    Micro Tunnel Boring Machines (MTBMs) are transforming urban underground construction in densely populated areas, offering efficient, precise, and minimally disruptive solutions for utility installations. These remotely operated machines excavate soil and rock to create small-diameter tunnels for water, sewage, telecommunications, and power supply lines, making them indispensable where traditional excavation methods are impractical.

    Why Choose MTBMs?

    1. Minimal Surface Disruption: Operates below ground, avoiding road closures and surface excavations.
    2. Precision Steering: Laser or gyroscopic guidance systems ensure accurate alignment and directional changes.
    3. Environmental Benefits: Eliminates extensive surface excavation, preserving ecosystems and reducing noise pollution.
    4. Enhanced Safety: Remote operation minimizes worker exposure to hazardous underground conditions.

    TSM’s MTBM Portfolio

    At TSM, we design and manufacture MTBMs tailored to specific applications and ground conditions. Below are the main types :

     

    1. Slurry Type MTBM – ASM
    • Design: Compact with a robust cutting head, hydraulic controls, and slurry separation system.
    • Operation: Uses slurry to balance pressure, cool the cutter, and remove excavated material.
    • Best For: Mixed ground (soft soils, clay, rock) in urban areas for small-diameter tunnels (100–1200 mm).
     
    1. EPB Type MTBM
    • Design: Shielded body with advanced sensing technology for stability and efficiency.
    • Operation: Maintains earth pressure; mixes soil with conditioning agents for slurry transport.
    • Best For: Cohesive/non-cohesive soils (sand, clay) in urban utility tunnels (1–5 meters diameter).

    1. Open Mode Type MTBM
    • Design: Compact with integrated launch/retrieval systems for minimal surface disruption.
    • Operation: Excavates soil while installing precast concrete liners.
    • Best For: Soft to moderately hard soils (clay, sand, silt) in urban utility and railway tunnels (0.5–3 meters diameter).
     
     
     
     
     
     
    1. Partial Face Type MTBM
    • Design: Compact with a partial face cutter head, thrust system, and propulsion mechanisms.
    • Operation: Excavates soil while installing lining segments to minimize ground disturbance.
    • Best For: Mixed ground (clay, sand, rock) in constrained urban environments (0.5–3 meters diameter).
    1. Full Face Type MTBM
    • Design: Robust frame with cutting tools and integrated support systems for tunnel lining.
    • Operation: Rotating cutterhead excavates soil while supporting the tunnel with pre-cast segments.
    • Best For: Varying ground conditions (soft soils to rock) in urban utility tunnels (1–4 meters diameter).
    1. Micro Gripper
    • Design: Compact and adaptable for unstable, variable ground conditions.
    • Operation: Excavates while stabilizing the tunnel face in sensitive environments.
    • Best For: Soft ground (clay, silt, loose rock) in urban areas (1–3 meters diameter)
