Self-supporting formwork system designed for pouring the tunnel ceiling. This formwork is composed of key panels that shape the tunnel ceiling and a supporting structure (cart) that connects to it. The key consists of 2 panels, each 2500 mm wide, forming a 5000 mm assembly. Additionally, the formwork will include a 100 mm overlapping piece in the rear section that overlaps with the previous section (5100 mm). This formwork system is equipped with an additional telescopic side panel that allows for lateral adjustment to the tunnel wall (only on one side).
