Over the last two decades IGNIS has been used in many tunnels, primarily to provide passive fire resistance to the concrete structure, whether this is a segmental tunnel lining, sprayed or cast in-situ concrete.

The complete lifting solution we designed for inside a tunnel boring machine (TBM) consists of two vacuum lifters. The first vacuum lifter transports the tunnel segments and keystones to the segment feeder of the erector. To meet the erector’s position the suction pad is able to rotate 90 degrees during the transport. Vacuum lifter as part of the erector The second vacuum lifter operates as part of the erector and perfectly matches the interface of the TBM. To meet every required position the lifter is able to turn 360 degrees.

Advantages of the structure marker signs: 1) Impact-resistant, UV resistant and weather-resistant material (ASA) 2) Coloured-through letter and numeral inserts for long-lasting identification marking 3) Patented self-fixing system ensures that numerals and letters remain resistant to shocks and impacts 4) Mounting without screws, thanks to the secure snap-in closures

Novelty Steel Designs and manufactures formworks for tunnel constructions and secondary lining works. We produce bespoke steel frames based on the client drawings and preferences. Our modern steelwork fabrication shops have computer-aided design and detailing (CAD), which is linked directly to factory floor computer numerically controlled (CNC) machinery, creating a genuine seamless CAD/CAM environment. The accuracy of the computer-generated details being transmitted directly to the CNC machinery increases the quality standards of the production. Novelty Steel has adapted EN 1090-2 standards into its manufacturing processes supervised by experienced quality management team.
