VENTILATION SYSTEMS FOR PUBLIC WORKS AND UNDERGROUND BASEMENT

Ventilation systems

SUB’ROCA offers innovative and tailor-made solutions for permanent and temporary ventilation adapted to your underground or « top-down » works, including the construction of station boxes or shafts.

SUB’ROCA’s response to these challenges is to develop turnkey ventilation solutions to achieve high performance. Our solutions will reduce energy costs and increase safety. 

Permanent ventilation

SUB’ROCA provides ventilation solutions to address the problems encountered in restrictive and aggressive environments where vehicle pollution gases and other environmental conditions generally affect the life of ventilation systems, reducing performance and safety.

Temporary ventilation

There are discrepancies between the ventilation required during the construction phase and the operation phase. Indeed, during construction, the majority of workers are in the area near the face of the tunnel or excavation, which is the area where the constraining gases are located. It is essential that the oxygen from the entrance of the tunnel or excavation flows into the front area in order to optimise working conditions.

Various configurations

We are able to design fans ranging from single stage (1 stage) to multi-stage (up to 4 stages) adapted to the constraints and phasing of your site based on the following characteristics: 

  • Casing made of S235JR steel with galvanised or epoxy paint finish.
  • The motors supplied have, depending on the case, a supply voltage of 230/400V or 400/690V (230V single phase/1000V or other on request).
  • Our fans are equipped with support feet as standard, but can be optionally mounted on fixed or mobile chassis (wheels, sledge/skid, etc.) for ease of movement.
  • The propellers are made of blades whose material varies according to the application propylene, glass-fibre reinforced propylene, aluminium, antistatic plastic. Thanks to our high quality materials and our design software, we can provide you with the propeller best suited to your constraints. Being at the forefront of propeller technology is part of our commitment.

Ventilation ducts and networks

Spiral ducts

Spiral ducts

Contact our engineering office

Flexible spiral ducts, more commonly known as « Spiragaines » are ducts that allow a fluid, in this case air, to circulate, which may be loaded with pollutants, dust or gas. They can be used for either blowing or suction (in overpressure or underpressure) and can be connected by different technologies (belts, straps, zip,…).

They are originally produced with 550g/m2 PVC, but can be produced with PVCs from 300 to 1000g/m2 on request and are packaged in sections of 5, 10, 15 or 20 metres.

Smooth flexible ducts, more commonly known as « Ventubes », are ducts for the circulation of a fluid, in this case air, which can be loaded with pollutants, dust or gas. They are used for blowing and can be connected by different technologies (belts,
straps, zip,…).

They are originally produced with PVC of 550g/m2, but can be produced with PVC from 300 to 1000g/m2 on request. They are packaged in sections of 5, 10, 15 or 20 metres. They can also be produced on the basis of several tens, or even hundreds of metres if a sheathed cassette is used, particularly for digging work by tunnel boring machines.
