Hard Rock Micro Tunneling Machine

Product Overview

The Hard Rock Pipe Jacking Machine is high-performance underground tunneling equipment specially designed for trenchless construction projects in hard rock, weathered rock, and mixed geological conditions.

This Rock Pipe Jacking Machine integrates advanced full-face excavation technology with intelligent monitoring systems to provide stable excavation performance and accurate directional control during underground tunneling operations.

As a professional micro tunneling machine and MTBM solution, the equipment is widely used in municipal underground utility engineering, sewer tunneling projects, and long-distance underground pipeline installation projects.

Compared with traditional trenchless construction equipment, this hard rock micro tunneling machine provides higher excavation efficiency, stronger geological adaptability, and improved operational stability in difficult underground environments.

Hard Rock Excavation Technology

The full-face excavation structure is specially developed for underground tunneling in hard rock and complex geological formations.

This Hard Rock Pipe Jacking Machine adopts high-strength disc cutters to continuously excavate rock formations while maintaining stable tunneling pressure and excavation efficiency.

The cutter head system is equipped with two independent grouting systems for the cutter head panel and the main shaft center, improving lubrication performance and reducing cutter wear during long-distance underground excavation projects.

The rear section of the machine is equipped with a main push device and anti-deflection control system, ensuring tunneling accuracy and stable alignment during trenchless pipeline installation operations.

This MTBM equipment is suitable for municipal trenchless engineering projects requiring high excavation capability and reliable underground tunneling performance.
