Steel Tunnel Segment | Steel Lining Segments for Shield Tunnels
Steel segments are special lining components in shield tunnels, commonly used at openings or locations with special loading. K.C.F. can manufacture them to your drawings and hot-dip galvanize them.
What Is Steel Tunnel Segment?
A shield tunnel is lined ring by ring with multiple segments. Besides the common concrete segments, steel segments welded from steel plate are often used at cross-passage openings, shaft connections or locations with special loading. Steel segment dimensions and bolt hole positions must match precisely, so they are usually custom-made to design drawings.
Every piece must be precise to complete the ring.
Key Features of Steel Tunnel Segment
Suited to Special Locations
Used at openings, connections and special load locations that concrete segments cannot easily handle.
Precisely Matched Bolt Holes
Made to drawings to match the dimensions and bolt hole positions of existing segments.
Custom OEM Manufacturing to Your Drawings
We can fabricate to drawings and specifications provided by the owner, designer or contractor, and can evaluate both small-lot and volume orders.
One-Stop Service from Fabrication to Galvanizing
Materials, cutting, welding and hot-dip galvanizing are handled together, reducing the time spent on transport and coordination between plants.
Typical Applications of Steel Tunnel Segment
- MRT shield tunnels
- Cross-passage openings
- Shaft connection sections
- Sewer and power tunnels
- Utility tunnel projects
- Tunnel repair and reinforcement
Why Choose Hot-Dip Galvanizing for Steel Tunnel Segment?
Steel exposed to rain, humidity and air pollution over time rusts easily, and corrosion resistance is the key factor in component durability.
Hot-dip galvanizing immerses steel in molten zinc, so the zinc coating bonds tightly with the steel and fully covers surfaces, edges and holes. Even if the coating is locally damaged, the surrounding zinc corrodes first to protect the steel. For steel tunnel segment, hot-dip galvanizing reduces the need for future rust removal and repainting.
K.C.F. specializes in hot-dip galvanizing, carrying out pretreatment, dipping and inspection in accordance with the relevant standards so every batch of components has consistent coating quality.
