2 Euroform Short Introduction Euroform was established in Euroform a été fondé en By a specialized team of technicians coming from Sicea, Euroform offers more than 40 years of experience in design and manufacture of segment moulds for precast tunnel lining and tunnelling formwork for cast-in-situ lining for drill & blast tunnel projects. Grâce à une équipe des techniciens spécialisés qui arrivent de Sicea, Euroform vous offre plus de 40 années d'expérience dans la conception et production de moules pour voussoirs préfabriqués et de coffrage pour tunnel avec béton coulé en place, quand le tunnel est excavé par des méthodes de forage et de dynamitage. Since 2006 is a 100% Subsidiary of Herrenknecht AG. Depuis 2006 Euroform est une société filiale 100 % de Herrenknecht AG.

19 Euroform Poliradial System (EP System) What is EP System? It is a modular steel formwork for cast in situ tunnel lining. The shutter is similar to a conventional one, with casting pipes, inspection hatches, vices for vibrators installation, walkways, etc but made of modulus of standard size that can be assembled all together to fit different tunnel section profiles.

20 Euroform Poliradial System (EP System) Which tunnel profiles? The shutter is designed to perfectly match the profile of a circular tunnel section with a radius of 5,80 m, but the system can be easily adapted to a full range of sections from a minimum theoretical radius of 4,30 m up to a maximum theoretical radius of 8,90 m. Deviations: mostly lower than 5 mm - Maximum 20 mm locally. The average deviation from the theoretical profile is lower than 10 mm.

23 Euroform Poliradial System (EP System) Versatility How does it work?

24 Euroform Poliradial System (EP System) Main features: Skin 10 mm thick (conventionally is 8 mm only). The side elements of each modulus are thicker and more strength than a conventional shutter. Special connection between elements allows to keep the right shape (according to the tunnel profile) during the erection and to transfer the strengths correctly. Modular design higher versatility.

25 Euroform Poliradial System (EP System) Benefits: The 10mm thick skin and the high robustness of the equipment permit more than thousand of reuses maintaining the high quality of the cast. The same shutter is not designed for a single tunnel but it can be used in different tunnels of the same job-site and/or in different projects. The SAME shutter can be used in self-reacting configuration as well as with anchorages at the bottom. The position of working platforms can be adjusted each time as per own convenience. All these modifications are carried out without cutting & welding works but simply bolting the original elements. No additional cost for refurbishment.

26 Euroform Poliradial System (EP System) Benefits: The equipment is made of standard modulus of appropriate dimensions and shape that can be quickly and properly handled, saving time and space and consequently having costs reduction for: o LOADING, o TRANSPORT, o STORAGE.

27 Euroform Poliradial System (EP System) Benefits: LOADING: because the modulus have the same size and they are easier and quicker to be handled.

28 Euroform Poliradial System (EP System) Benefits: TRANSPORT: because the modulus have the right size to properly fit the length and the width of trucks/containers. A COMPLETE SHUTTER 260 m 2 LOADED ON 3 TRUCKS OR CONTAINERS 3,0 12,0 1,6 2,2

29 Euroform Poliradial System (EP System) Benefits: STORAGE: a smaller area for stocking is requested because the modulus have the right size and shape for saving space when stacked.

30 Euroform Poliradial System (EP System) Benefits: The equipment is made of standard modulus therefore the EP Shutter: o Guarantees higher quality standards. o Can be implemented (adding or removing some modulus) every time according to the job-site needs. o The accessories are standard as well. o Can be provided in shorter time. o Has a high market value. o Has a high buy-back value.
