Tunnel High Angle Sidewall Conveyor Belt Solutions

Tunnel and hydraulic engineering construction faces unique and harsh mucking transportation challenges. Shield tunneling operations take place in fully enclosed, narrow underground spaces, with no room for frequent equipment adjustments or shutdowns. The on-site muck features large output volume, high water content, sticky texture and mixed hard rock fragments, which easily cause common problems for ordinary conveyor belts, including material adhesion, insufficient impact resistance, belt deformation, material leakage and short service life. These issues directly slow down tunneling progress and raise overall construction costs.

Tailored exclusively for tunnel and hydraulic construction working conditions, QBF rubber corrugated sidewall conveyor belts solve the core pain points of underground mucking transportation. We optimize product structure and material performance targeting high-water sticky muck and high-impact rock slag. Our custom belts deliver anti-stick, easy-clean, high-capacity and long-lasting conveying performance, enabling efficient, safe and hassle-free mucking removal for various tunnel and hydraulic projects.

Tailored Structural Advantages for Tunnel & Hydraulic Working Conditions

Impact-Resistant Cleat Design for Heavy Muck Loads

Tunnel mucking involves frequent impact from falling rock fragments and heavy wet soil. Ordinary cleats are prone to cracking, peeling and deformation under continuous heavy impact. QBF rubber upgrades the cleat structure with reinforced rubber layers and integrated molding technology. The enhanced impact resistance effectively withstands repeated strikes from hard slag and bulky muck, avoiding structural damage and ensuring stable material carrying capacity during long-term tunneling operations.

High-Rigidity Transverse Base Belt Against Deformation

Limited enclosed tunnel space makes belt deviation and deformation extremely problematic, with almost no margin for on-site correction. Our tunnel-grade base belt adopts a high-rigidity reinforced structure. It maintains stable flatness and tension even under full-load wet muck transportation and long-distance telescopic operation. This design effectively prevents lateral distortion, sagging and deviation, greatly reducing equipment adjustment frequency and adapting to narrow underground construction environments perfectly.

High-Performance Corrugated Sidewalls for Anti-Leakage Conveying

Wet, high-water-content tunnel muck easily slips and leaks during inclined conveying, causing site mess and reduced transportation efficiency. Our optimized high-elasticity reinforced sidewalls fit tightly with the cleat structure. They block wet slag and fine soil effectively, eliminating material leakage and back-slip. The flexible yet sturdy sidewall structure also avoids rigid cracking under frequent load changes, ensuring continuous and clean mucking delivery.

Anti-Stick & Easy-Clean Surface for Wet Muck

High-humidity tunnel muck tends to stick firmly to ordinary belt surfaces, leading to material accumulation, increased operational resistance and secondary cleaning work. QBF rubber adopts a special anti-stick rubber formula for the working surface. It prevents sticky wet soil and fine slag from adhering, and residual materials can be cleaned easily with conventional belt cleaners. This self-cleaning performance keeps the conveying line efficient with minimal manual maintenance.
