What rebar machines are used in tunnel construction?
Quick answer: tunnels need arc bending machines for curved liners and reinforcement, plus standard cutters and benders for the rest.
Recommended set:
- GDWHWQ-36 — arcs and hooks on Ø16–36 mm, 0–120°
- SKDZWH-36 — CNC servo arcs up to Ø40 mm with repeatable radii
- GWH50CG — simple large-radius arcs on Ø50 mm
Why it matters: tunnel liners need consistent radii; a CNC servo arc bender holds the radius across hundreds of bars where manual bending drifts.
How to buy: give us your liner radius and bar diameter; we quote the right arc bender.
