FIELD: construction.
SUBSTANCE: method for moving-out and return of a football field for a covered stadium consists in displacement of a grass coating fixed on a flexible substrate and arranged on a flat rigid board, relative to the rigid flat base beyond the stadium borders and back. Operations of the movement in both directions of the flat board are carried out by means of the base inclination towards the movement side in case of gravity displacement along the board base, and the base is equipped with rolling supports, with the board braking at the end sections of its movement in both directions.
EFFECT: simplified mechanism of movement and reduced labour intensiveness and time of operations performance to remove and return the coating into the initial position.
