Unblocked plastic drainage plate is the filter membrane and core plate through a special process, this special structure makes it has the characteristics of good integrity, high tensile strength, large water flow. Or the core plate and the filter membrane separation of the anti-blockage drainage plate, according to the clay particle size distribution in the silt flexible adjustment of the pore size of the filter membrane, can effectively overcome the clay particles around the drainage plate filter membrane enrichment caused by the blockage phenomenon, to achieve the ideal smooth effect.
