Large Diameter Hard Rock Pipe Jacking Machine

Product Overview

The Large Diameter Rock Pipe Jacking Machine is high-performance underground tunneling equipment specially developed for trenchless construction projects in hard rock, weathered rock, and mixed geological formations.

This Rock Pipe Jacking Machine adopts advanced full-face excavation technology and intelligent monitoring systems to achieve stable tunneling performance and efficient rock excavation capability during underground construction operations.

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

Compared with conventional trenchless construction equipment, this large diameter rock micro tunneling machine provides stronger excavation capability, more stable directional control, and improved tunneling efficiency in difficult underground geological environments.

Large Diameter Rock Excavation Technology

The full-face excavation structure is specially optimized for large diameter underground tunneling and hard rock trenchless construction projects.

The rock Pipe Jacking machine adopts high-strength disc cutters to continuously excavate hard rock formations while maintaining stable tunneling pressure and precise alignment control.

Two independent grouting systems are configured for the cutter head panel and the main shaft center, effectively improving lubrication performance and reducing cutter wear during underground excavation operations.

The rear section of the machine is equipped with a main push system and an anti-deflection device, improving directional stability and tunneling accuracy during long-distance underground pipeline installation projects.

This large diameter micro tunneling machine is suitable for municipal trenchless engineering projects requiring high excavation efficiency and reliable rock tunneling capability.
