The square frame integrally surrounds the side surfaces of sidewalk blocks. The support members are integrally formed on the square frame and have multiple horizontal and vertical supports(210,230). The protrusion members are protruded from the bottoms of the horizontal and vertical supports and are integrally formed on the square frame and the support members. |
