The utility model discloses a multi-stage gradient drainage and three-dimensional anti-seepage descending plate area composite waterproof structure, which relates to the technical field of descending plate areas, and comprises a descending plate area main body, an inclined panel is arranged in the descending plate area main body, the bottom surface of the inclined panel is fixedly connected with the inner wall of the descending plate area main body, the two ends of the inclined panel are respectively provided with a downward inclined surface, and the inclined surface is fixedly connected with the inner wall of the descending plate area main body. Drainage grooves are formed in the left end and the right end of each inclined panel, the two drainage grooves correspond to the inclined planes on the two inclined panels, when accumulated water exists on the inclined panels, the accumulated water can flow into the drainage grooves in the two ends along the inclined planes on the inclined panels, when the accumulated water flows into the two drainage grooves, drainage plates in the two drainage grooves can guide the accumulated water to flow into a water outlet, and a water pump is started; the water pump can absorb and drain accumulated water in the plate descending area main body, so that the plate descending area main body has a drainage function, and the problems that the accumulated water enables the ground to be in a humid state for a long time, damage of ground materials is accelerated, and attractiveness and use functions are affected are solved.
