FORMWORK FOR TUNNEL ELEMENTS

Our formworks are custom-made, thus enabling to produce any type of element. Their design often contemplates the need to produce end products in an on site mobile building yard under harsh environmental conditions and often with low specialised personnel. Our formworks can be easily moved between several yards and need limited foundation building works.

This equipment enables to produce the main elements required to build a tunnel:

  • Side walls
  • Central walls
  • Vault or flat girders

Each formwork can be integrated with hydraulic systems accelerating the operations and automating the production process.

On request, we can provide each formwork with a system for compacting the concrete in conjunction with an electrical or pneumatic vibrator at variable frequency and a heating and insulation system to accelerate the concrete element’s curing process.

Any coupling between formwork movable parts (such as at bottom/side walls) where there are opening and closing actions is provided with GF metal or rubber gaskets against the cement grout.
