Precast concrete ring
This EPD presents a cradle-to-gate declaration of the environmental performance of 1 m3 of “Precast concrete ring” used for the lining of the Exploratory Tunnel CE of the Brenner Base Tunnel (CE ring). It covers the production of raw materials, their transport, the production phase of semi-finished products, components and segments.
Each CE ring is made up of:
- 6 prefabricated segments (5 + 1 keystone), equipped with gaskets for hydraulic sealing, guide bars for correct positioning and inserts for the mounting process;
- 2 prefabricated segments used as a support base for the realization of the final plan (base segment 1 and base segment 2).
