Abstract (en)
A system for manufacturing a service structure for the support of men and means working to consolidate the ground around a tunnel (G) overlying a way (S), the latter having a longitudinal extension along a first axis (X) and at least one opening (A) for the passage of one or more vehicles. The system comprises a load-bearing structure (100) having an extension along a second axis (Y) intended to be positioned above the way (S) at the at least one opening (A) of the tunnel (G) which comprises one or more support areas (110) for men or means during the operation, and a protection wall (200) designed to be interposed between the load-bearing structure (100) and the way (S). The protection wall (200) is substantially continuous so as to prevent men or objects from falling on the way (S).
