Ventilating Deep Pipe Jacking Operations

Project Overview

A major underground pipe jacking project, crews were working deep below ground with limited natural airflow.

Challenge

During a major underground pipe jacking project, crews were working deep below ground with limited natural airflow. The challenges were clear:

• Supply fresh air through kilometres of ducting into confined spaces.
• Protect workers from the build-up of harmful fumes.
• Maintain compliance with WHS standards for underground ventilation.

The contractor required a powerful and reliable system that could deliver clean, breathable air consistently across long distances.

Solution

RVT Group’s Technical Consultants designed a tailored ventilation system built around our high-performance, industry-leading centrifugal fans. These units were capable of:

• Generating the pressure required to push fresh air through extended ducting runs.
• Ensuring constant airflow even under demanding site conditions.
• Maintaining safe oxygen levels and diluting hazardous contaminants.

This engineered approach provided crews with a consistent supply of fresh air, creating a safer and more productive underground work environment.

The results

The outcome was a robust, compliant ventilation system that:

Demonstrated the reliability of RVT Group’s centrifugal fans — pumping air through kilometres of ducting without missing a beat.

Safeguarded workers’ health by maintaining clean, breathable air underground.

Ensured pipe jacking operations could proceed without delays caused by ventilation issues.
