JD Series 4×6m Rectangular Micro Tunneling Machine

Product Overview

The 4×6m Rectangular Pipe Jacking Machine is a large-section trenchless underground tunneling system independently developed by Guangxin Heavy Industry for municipal utility corridors, underground transportation infrastructure, and smart city construction projects.

This JD series rectangular Pipe Jacking Machine integrates advanced combined cutterhead excavation technology with intelligent rectangular tunneling systems to improve underground construction efficiency and optimize usable tunnel space.

As a professional rectangular micro tunneling machine and MTBM solution, the equipment is widely suitable for underground pipeline galleries, subway auxiliary tunnels, municipal passageways, cable corridors, and urban infrastructure engineering projects.

Compared with traditional circular excavation equipment, the rectangular shield tunneling structure provides higher underground space utilization and supports more efficient installation of municipal utility systems.

Large-Section Rectangular Tunneling Technology

The machine adopts advanced large-section rectangular excavation technology for efficient trenchless underground construction in complex urban environments.

The combined cutterhead system improves excavation capability and provides stable tunneling performance in soft soil, mixed formations, sand layers, gravel, and other complicated geological conditions.

This rectangular micro tunneling machine maintains accurate alignment control and stable excavation pressure during long-distance underground tunneling operations.

The trenchless excavation process significantly reduces road excavation, surface settlement, environmental impact, and traffic disruption during municipal engineering construction.

The equipment is highly suitable for underground infrastructure projects requiring efficient excavation capability, sustainable construction methods, and reliable operational stability.
