[0024] Beneficial effects:

[0025] (1) The sawtooth waterproof drainage structure enters into the inner wall of the placement groove on the outer edge of the top wall of the drainage board through the reinforcing ribs, and drives the short rod and the rubber seat to enter into the receiving seat and the inner wall of the limit opening of another drainage board through the connecting seat, so that the rubber seat passes through the limit ring to be fixed, and the short rod fits with the inner wall of the limit opening. The drainage boards are arranged and installed in sequence. When external water passes through the surface of the drainage board, it flows into the water collecting cover through the drainage port and is discharged from the drainage hole. However, dust and impurities in the water remain in the water collecting cover. When the drainage board is paved over a large area, it is not necessary to use a large number of bolts and nuts for installation. In addition, the overall installation structure is simple and convenient, and the time required is short. The paving work efficiency is improved, and the overall strength of the drainage board can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
