1. A system for reversibly converting stadiums into multifunctional infrastructures by means of removal and storage of a playing field in a pit (6) located parallel to the playing field, the playing field having a plurality of sides, the system comprising:
an assembly of trays (1) on which the playing field is located, wherein each of the trays of the assembly of trays (1):
is movable from or towards the pit (6);
has a length equal to a total length of the playing field in a longitudinal direction of the pit (6);
is self-supporting; and
houses layers of the playing field and natural or artificial turf;
a transport system for guided hoisting and transverse horizontal shifting of each tray of the assembly of trays (1), and configured to move each tray of the assembly of trays from a position on the playing field to a vertical position in the pit (6);
an assembly of retractable lattice girders (5) comprising a plurality of retractable lattice girders, configured for being deployed over the pit (6);
a lifting system (8) installed in the pit (6) configured for lowering vertically each tray of the assembly of trays to a final storage position, or lifting each tray of the assembly of trays from the final storage position;
a storage system (7) installed in the pit (6) for storing each tray of the assembly of trays,
wherein the transport system is a horizontal transport system comprising an assembly of autonomous transport carriages (2) comprising a plurality of transport carriages, guided by means of a system selected from rails or an inductive guidance system in a support slab (4), for transversely transporting each tray of the assembly of trays wherein the plurality of transport carriages (2) comprises a quantity of between ten and twenty-two transport carriages for supporting each tray (1) when each tray of the assembly of trays (1) when each tray of the assembly of trays is configured in a longitudinal direction of the playing field; and wherein the plurality of transport carriages (2) comprises a quantity of between four and twelve transport carriages for supporting each tray of the assembly of trays when each tray of the assembly of trays is configured in a transverse direction of the playing field; and wherein a number and a position of the plurality of retractable lattice girders (5) of the assembly of retractable lattice girders coincide with a number and a position of the plurality of transport carriages of the assembly of autonomous transport carriages (2).
