Cross-section variety
Diameters range from 2 m to 15 m. Travellers are built to the section, not a generic ring.
SOLUTION 05 Tunnel & Mining
Tunnel lining and underground formwork systems for variable geometry in restricted spaces. Full-round travellers, telescopic forms, and curved steel panels for underground construction.
TECON tunnel formwork covers circular, horseshoe, and multi-cell cross-sections. Custom-engineered travellers with hydraulic advance and invert systems enable efficient lining cycles.
Full-round travellers complete one-pass lining with integrated working platforms. Telescopic design allows form retraction and movement without full stripping between pours.
Recommended tunnel formwork by cross-section type.
| Application | Dimensions | Recommended System | Key Advantage |
|---|---|---|---|
| Utility tunnels | 2–6 m | Telescopic form | Non-portable components |
| Highway / metro | 6–15 m | Full-round traveller | One-pass lining |
| Mining shafts | Variable | Curved steel panels | Corrosion resistant |
| Horseshoe sections | 5–10 m | Custom traveller | Complex geometry |
Common tunnel conditions solved by TECON systems.
Diameters range from 2 m to 15 m. Travellers are built to the section, not a generic ring.
Invert and crown are poured with an integrated platform so the traveller does not fully strip between pours.
Mining and wastewater linings need corrosion-resistant, galvanized forms.
Underground access is tight. Forms break into man-portable components for assembly inside the tunnel.
