System for reversibly converting stadiums into multifunctional infrastructure

A system for reversibly converting stadiums into multifunctional infrastructures by means of the removal and storage of a playing field in a pit (6) located parallel to the playing field comprising:

• an assembly of trays (1) on which the playing field is located, wherein the assembly of trays (1):
• are movable from or towards the pit (6);
• have a length equal to a total length of the playing field in a longitudinal direction of the pit (6);
• are self-supporting;
• and
• houses layers of the field, an irrigation system, and natural or artificial turf;
• a transport system for a guided hoisting and transverse horizontal shifting of each tray of the assembly of trays (1) from a position thereof on the playing field to a vertical position of the pit (6), or each tray (1) bears its own monitoring for the shifting thereof;
• an assembly of retractable lattice girders (5), configured for being deployed over the pit (6);
• a lifting system (8) installed in the pit (6) configured for lowering vertically each tray to a final storage position, or lifting it from the final storage position;
• a storage system (7) installed in the pit (6) for storing each tray, which moves only vertically in a fixed and stable position.
