The present invention relates to a hollow cut-off plate with a multidirectional wrinkle unit. The hollow cut-off plate with a multidirectional wrinkle unit includes a multidirectional wrinkle unit which is formed of a wrinkle hollow and a wrinkle frame surrounding the wrinkle hollow and directionally stretched by a predetermined pressure and extension force and which is bent at an angle of 90 degrees in a longitudinal direction and overlapping in multiple layers when bent; and first and second planar units integrally extending from both sides with respect to the multidirectional wrinkle unit. The hollow cut-off plate with a multidirectional wrinkle unit can be easily installed in a concave groove formed between bonding surfaces of both concrete box culverts facing each other, can be stretched with the movement of the concrete box culverts, and can be easily inserted and coupled into an edge part of the box culvert. |
