PU plastic runway

The utility model discloses a PU (polyurethane) plastic runway, which relates to the technical field of plastic runways and particularly comprises an outer side layer mechanism, a water seepage layer is arranged below the outer side layer mechanism, a buffer layer mechanism is arranged below the water seepage layer, a base layer mechanism is arranged below the buffer layer mechanism, and a drainage pipe is arranged in the base layer mechanism. The outer side layer mechanism comprises a wear-resisting layer, anti-skid particles are arranged in the wear-resisting layer, the bottom of the wear-resisting layer is arranged above the water seepage layer, the buffer layer mechanism comprises a soft layer, a water drainage pipe is arranged in the base layer mechanism, water in the base layer mechanism is rapidly drained through the water drainage pipe, and the water seepage layer is arranged in the buffer layer mechanism. Rainwater is drained to avoid soaking, so that the problems that the existing plastic runway is
