Quick and efficient permeable pavement brick for sponge city drainage system

The utility model relates to a quick and efficient permeable pavement brick for a sponge city drainage system. An inverted circular truncated cone-shaped mounting hole is formed in the center of the top of the permeable pavement brick; an inverted-circular-truncated-cone-shaped water permeable cover plate is installed in the installation hole, a plurality of inclined first water leakage grooves are formed in the hole wall of the installation hole, a plurality of inclined second water leakage grooves are formed in the outer side wall of the water permeable cover plate, the first water leakage grooves and the second water leakage grooves are spliced to form water leakage holes, and a water storage groove with the front end and the rear end being semi-closed is formed below the installation hole. The permeable pavement brick has the beneficial effects that most of rainwater falling on the permeable pavement brick can be quickly guided into the water storage tank through the water leakageholes, and a small part o
