Permeable pavement brick

The invention discloses a permeable pavement brick. The permeable pavement brick comprises a cuboid portion, wherein a first wavy clamping portion and a second wavy clamping portion are respectively arranged on side walls of two ends of the cuboid portion; the axis of a wave crest of the first clamping portion and the axis of a wave trough of the second clamping portion are positioned on the same straight line; two wavy third clamping portions and two wavy fourth clamping portions are respectively arranged on side walls of two sides of the cuboid portion; and the axis of a wave crest of each third clamping portion and the axis of a wave trough of the corresponding fourth clamping portion are positioned on the same straight line. Wave crests on the first clamping portions, the second clamping portions, the third clamping portions and the fourth clamping portions of adjacent bricks are inserted in the corresponding wave troughs, a plurality of gaps are formed among the adjacent bricks, the bricks can be interlocked stably, and water can permeate rapidly. The permeable pavement brick has the advantages of large water permeation amount, good water permeation effect, stable structure, difficulty in looseness, easiness in seam cleaning and the like.
