Curious about how this performs in practice? Join us for a hands-on look at our arc-shaped tunnel steel formwork in action. This video demonstrates how its precision arc design ensures stable tunnel linings by fitting perfectly with curved tunnel contours, preventing slurry leakage during concrete pouring. You'll see the modular assembly process in confined spaces and learn how it maintains rigidity under concrete pressure for smooth, uniform lining results.
