JD Series Earth Pressure Balance Rectangular Micro Tunneling Machine

Product Overview

The Earth Pressure Balance Rectangular Pipe Jacking Machine is a next-generation underground excavation system independently engineered by Guangxin Heavy Industry for high-efficiency trenchless construction and complex municipal tunneling projects.

Unlike conventional circular tunneling equipment, this EPB rectangular Pipe Jacking Machine is specially designed to create rectangular underground spaces with improved structural usability and optimized utility installation capacity.

The machine integrates advanced earth pressure balance technology with intelligent excavation control systems, enabling stable tunneling operations in soft soil, clay, silt, sand layers, and mixed geological formations.

As a professional EPB rectangular micro tunneling machine and MTBM solution, the equipment is widely used in underground utility corridors, subway access tunnels, municipal pipeline systems, and smart city infrastructure development projects.

Advanced EPB Excavation Technology

The machine adopts an intelligent earth pressure balance control system capable of maintaining stable excavation chamber pressure during underground tunneling operations.

This EPB rectangular micro tunneling machine effectively controls ground deformation and minimizes surface settlement in densely populated urban construction environments.

The rectangular excavation structure allows more efficient utilization of underground space, making the equipment especially suitable for utility tunnel systems and underground transportation infrastructure.

The trenchless excavation process reduces the need for large-scale open-cut construction, helping lower traffic disruption and environmental impact during municipal engineering projects.

Integrated monitoring systems provide real-time excavation data, improving construction precision and operational safety throughout the tunneling process.
