JD5.5m × 9.1m Rectangular Pipe Jacking Machine for Utility Tunnel Project

Product Overview

The Suzhou Pipeline Gallery Rectangular Pipe Jacking Machine is specialized trenchless construction equipment developed for underground utility tunnel engineering, municipal pipeline gallery projects, and large-section urban underground infrastructure construction.

This rectangular Pipe Jacking Machine adopts advanced earth pressure balance tunneling technology and intelligent excavation systems to achieve stable underground construction performance in complex urban geological environments.

The JD5.5m × 9.1m rectangular micro tunneling machine was successfully accepted by China Railway 20th Bureau for the Suzhou utility tunnel project, demonstrating reliable tunneling capability and advanced manufacturing quality.

Compared with conventional underground excavation methods, this MTBM equipment significantly reduces surface disruption, improves construction safety, and increases underground space utilization efficiency for municipal engineering projects.

Large-Section Rectangular Tunneling Technology

The large-section rectangular excavation structure is specially designed for underground utility tunnel and pipeline gallery projects requiring efficient underground space utilization.

This rectangular micro tunneling machine provides one-time tunnel forming capability, reducing excavation volume and improving overall construction efficiency during trenchless underground engineering operations.

The earth pressure balance excavation system effectively controls surface settlement and minimizes disturbance to surrounding underground structures during urban construction projects.

Compared with traditional circular tunneling equipment, the rectangular Pipe Jacking machine provides more practical usable underground space for utility tunnel systems, cable corridors, and municipal pipeline installations.

The intelligent control system maintains stable excavation pressure and accurate directional control during long-distance underground tunneling operations.
