Segments for tunnel coatings

Circular section segments of quick and easy assembly are used both as formwork and finished element in the coating realization of natural and artificial tunnels by modifying their radius in presence of extensions for the construction of lay-bys or emergency or deceleration lanes, short realization times and significant cost savings can be permitted by substituting the proper casting formwork. Artifacts are prefabricated products complete with bushings for attaching cribbing and regulators and mouths for concrete casting until their complete clogging.
