Tunnels

Tunnels - Covertechnology.com

Using state-of-the-art technology, Cover Technology is able to produce load-bearing structures and covers in fabric membrane suitable for the construction of strong, solid tunnels. This vast range of products can be used to form connections between containers, field tents and other facilities, with the maximum protection against the weather ensured at all times. If necessary, Cover Technology tunnels can be completely removed without jeopardising the stability of the other adjoining structures. The TUNNEL construction consists of an aluminium and steel frame covered with technical PVC fabric membrane or sandwich panels. The choice of materials allows shipping low weights and compact volumes, rapid assembly and impressive resistance to weather loads.

CONFIGURATION
Width Minimum 04.00 metres / Maximum 30.00 metres
Length Standard modules 05.00 metres / total length infinite
Side height Minimum 02.50 metres / Maximum 06.00 metres
Wind resistance Minimum 25 m/sec / Maximum 41 m/sec
Snow resistance Minimum 60 daN/m² / Maximum 400 daN/m²
Cover fire resistance class Self-extinguishing – Flame Retardant Class 2
Operating temperature -30 °C  /  +70 °C

The TUNNEL structure is of modular design, allowing:

  • DIFFERENT CONFIGURATIONS (open, enclosed, or with large doors)
  • INSTALLATION ON DIFFERENT SURFACES (asphalt, concrete, dirt, or sand) thanks to a special anchor system (with threaded bars, plates and nails or spiral bars)
  • DESIGN WITH A SPECIFIC SNOW BEARING CAPACITY, ranging from 60 kg/sq. m for the basic structure up to 400 kg/sq. m for areas with very high snowfall
  • CE MARKING of the structural components in compliance with the EN 1090-1:2009+A1:2011 standard thanks to Cover Technology’s accreditation. It is also important to note that structures are designed and constructed in compliance with the Italian Ministerial Decree dated 14.01.2008 (known as the Technical Construction Standards or NTC2008 with return time Tr 50 years) and in compliance with the Eurocodes.

The supporting frame consists of extruded aluminium alloy profiles, creating a lightweight structure that withstands all weather conditions. Roofs and side walls are in flame-retardant, waterproof, very tough, PVC fabric. Naturally, there is a very wide selection of materials to suit the different uses and locations of structures. The main materials used in construction of the TUNNEL STRUCTURE are:

MATERIALS
Main structure components Aluminium alloy profiles
Base plate elements Hot-dip galvanised steel
Cover Modular sheets of Class 2 Flame-Retardant PVC / Sandwich panels
Side walls, if required Modular sheets of Class 2 Flame-Retardant PVC / Sandwich panels
Doors or openings, if required Large vertical folding doors / folding vehicle doors / personnel doors
Metal cables Plastic-coated steel cable
Supporting surface Plinth not required
Anchor systems for concrete surfaces Threaded bars fixed with structural vinyl/epoxy resins
Anchor systems for firm ground and asphalt surfaces Steel nails driven into the ground
Anchor systems for loose ground Continuous spiral coils or rods

Apart from the STANDARD PVC sheeting, the cover may be in:

  • PVC fabrics with blackout treatment for sun protection
  • Thick PVC fabric membrane (strong cover)
  • Low-emission (silver-coated) or insulated PVC fabrics
  • PVC fabrics with special coating

Cover Technology over the years has realized several installations, please find below some related examples.

  • For the Republic Day in Rome, Cover Technology has produced a tunnel with sizes of 20×50 meters.
  • For the Fair organization in Brescia, Cover Technology has produced a tunnel with sizes of 05×45 meters.
