Background

With the development of urban construction, drainage plates and waterproof structures are commonly used in greening drainage systems of engineering constructions such as underground garages, roof gardens, planted roofs, basements, subways and the like. The drainage plate is formed by forming solid or cup-shaped bulges on a polymer sheet, wherein the cup mouths of the cup-shaped bulges are opposite to the bulges, the bulges are generally upward, and the spaces among the bulges form drainage channels. When the device is used, the drainage plates are flatly laid on the top plate, a layer of filter cloth is laid on the drainage plates, and then upper-layer structures such as greening soil and the like are laid on the filter cloth, so that permeated water is collected and drained away. However, the top ends of the cup-shaped convex structures on the drainage plate are sealed, in the process of contacting with the filter layer, accumulated water above the drainage plate cannot vertically and quickly seep downwards to be discharged, and the cup-shaped convex structures are distributed on the drainage plate in a large quantity and have large total contact area with the filter layer, so that the overall water seepage speed and the drainage efficiency of the drainage plate are influenced. In addition, direct filter layer of laying on the protruding structure of cup of drain bar, under superstructure's pressure effect, the filter layer sinks easily and warp or the breakage appears, influences the infiltration drainage effect of drain bar, and then can't in time drain off water, probably appears because of ponding too much soak plant roots and waterproof layer, leads to the phenomenon of plant death, top layer waterproof layer damage.
