Overview

Tunnel construction environments are fraught with challenges: humidity, dust, hazardous gases, and complex mechanical operations. A reliable and efficient ventilation system is crucial for ensuring worker safety and the smooth progress of construction projects. Our steel-ring-connected PVC ventilation duct is a specialized product designed for this purpose.

It utilizes a high-strength PVC composite material for the duct body, offering excellent corrosion resistance, aging resistance, and flame retardancy. Its key feature is its unique steel-ring connection design. Through its built-in coil spring steel ring, the duct maintains exceptional flexibility while enabling quick, airtight connections.

Simply put, this is a tougher, more convenient, and safer tunnel-specific ventilation duct, the unrivaled choice for ventilation systems in modern tunnel construction.

High-Strength PVC Material: The duct body is constructed from a specially modified polyvinyl chloride composite material, rather than ordinary plastic, resulting in exceptional mechanical strength that withstands impacts from tunnel debris and mechanical wear, extending its service life far beyond that of conventional canvas ducting. Excellent Corrosion Resistance: Completely unaffected by tunnel moisture, acidic and alkaline corrosive gases, it resists rust and corrosion like metal ducts, maintaining a smooth interior and ensuring unimpeded ventilation.

Flame Retardant and Antistatic: This product complies with tunnel construction safety standards, exhibits excellent flame retardancy, and effectively prevents static electricity accumulation, providing an added layer of safety in flammable and explosive construction environments.

Applications

Railway and Highway Tunnel Construction: Provides fresh air to the excavation face and removes dust and harmful gases generated by drilling, blasting, and shotcreting.

Subway Tunnel Construction: Provides ventilation in station areas and shield tunnels, ensuring safety in deep underground working environments.

Water Conservancy Culverts and Mining Roadways: Addresses common ventilation challenges in underground projects.

Large Pipeline Projects: Provides temporary ventilation during construction.
