Sidewalk or square permeable road structure

The invention relates to a permeable road structure of a sidewalk or a square. The permeable road structure comprises a cement mortar leveling layer, a permeable cement concrete layer, a roadbed, kerbs, plain concrete, a rainwater hopper, a rainwater grate and one-way and three-way duct permeable bricks. One-way duct water permeable bricks are arranged on the upper surface of the first cement mortar leveling layer, first longitudinal water guide holes are formed in the one-way duct water permeable bricks, the three-way duct water permeable bricks are arranged on the upper surface of the plainconcrete, and second longitudinal water guide holes, transverse water guide holes and vertical drainage holes are formed in the three-way duct water permeable bricks; in the inside-outside direction,the first longitudinal water guide holes in the adjacent one-way duct water permeable bricks are connected, and the second longitudinal water guide holes in the three-way duct water permeable bricks are connected with the firs
