The folding aisle 3 is pushed out to free up space for pedestrians to move. The folding aisle 3 includes a cross arm 5, an upper connecting shaft 6, a lower connecting shaft 7, a folding plate 8 and a driving mechanism. The cross arm 5 is provided with multiple groups, and the multiple groups of cross arms 5 are hinged to form two groups of folding wall barriers 31. The upper ends of the multiple groups of cross arms 5 in the folding wall barriers 31 are hinged through the upper connecting shaft 6, and the lower ends of the multiple groups of cross arms 5 in the folding wall barriers 31 are hinged through the lower connecting shaft 7. The two groups of folding wall barriers 31 are hinged through the lower connecting shaft 7. The folding plate 8 is connected to the upper and lower ends of the folding plates 3 and the lower and lower ends of the folding plates 3, so that the folding plates 3 can be folded.
