Segment Lining — Casting Plant Capacity
Casting Plant Capacity for segmental tunnel lining production and supply.
Casting starts months before launch precisely because plants can't sprint — molds are the fixed gear. The stockpile built pre-launch is the buffer that absorbs the TBM's best weeks; a plant sized exactly to average demand fails on the first record day.
Formula
Note: Planning-level tunnelling estimate — actual TBM performance is set by detailed geotechnical baseline data, machine design and the contractor's means & methods. Use for feasibility framing only.

About Segment Lining — Casting Plant Capacity
Segment Lining — Casting Plant Capacity computes the governing relationship rings/day = molds × casts ÷ segments-per-ring live as you type. Casting starts months before launch precisely because plants can't sprint — molds are the fixed gear. The stockpile built pre-launch is the buffer that absorbs the TBM's best weeks; a plant sized exactly to average demand fails on the first record day. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Segment Lining — Casting Plant Capacity
- 1Enter your values — Mold sets, Casts per mold per day, Segments per ring, TBM demand (sensible defaults are pre-filled).
- 2Read the live results: Plant output, Margin over TBM.
- 3Check the "with your numbers" line to see rings/day = molds × casts ÷ segments-per-ring substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
