Earth Pressure Balance Pipe Jacking Machine for Underground Trenchless Tunneling

Product Overview

The Earth Pressure Balance (EPB) Pipe Jacking Machine is an advanced trenchless construction solution designed for underground pipeline installation in urban and infrastructure projects.

By maintaining balanced pressure at the excavation face, the machine ensures stable tunneling operations, minimizes ground settlement, and improves overall construction safety. It is widely used in medium and large diameter Pipe Jacking projects.

With integrated soil conditioning technology, slurry or conditioning materials can be injected to improve soil plasticity, flowability, and impermeability, enabling efficient excavation in complex geological conditions.

Technical Performance and Features

The TP series Earth Pressure Balance Pipe Jacking Machine is independently developed by Guangxin Heavy Industry, offering reliable performance and advanced tunneling technology.
