The invention relates to a porous water permeable concrete curb. The invention is characterized in that a plurality of regularly arranged horizontal holes run through the front and back surfaces of the curb, so that road surface rainwater can be quickly and efficiently drained to a downward concave green land, the in-situ storage and infiltration utilization rate of rainwater can be improved, and at the same time large impurities drifting along with water can be prevented from entering the green land. The front of the curb provided in the invention is in the shape of a rectangle, a square or a regular hexagon, and the holes are regular in shape, beautiful, and perpendicular to the front and back surfaces, so that the curb is convenient to make and install, and can save materials and cut down on the manufacturing cost. After installation of the curb provided in the invention, each level surface between the top frame inner side and the road surface is provided with pores, which make the drainage ability of the curb not limited by curb burial depth and the road surface water level. And certain pores still exist in the part below the road surface, and can store water as well as promote the water penetration toward the green land. Thus, the combination of penetration and drainage can be realized.
