| description | The invention discloses a plastic drainage plate capable of being dissolved at intervals. The plastic drainage plate comprises a core plate, a filter membrane and dissolving sections, wherein the coreplate serves as a drainage channel, the filter membrane wraps the core plate, the dissolving sections are arranged on the filter membrane, the dissolving sections are connected end to end to form rings correspondingly, the dissolving sections are spaced from the tail end of the filter membrane, and the dissolving sections are made of a degradable water-permeable material. According to the plasticdrainage plate capable of being dissolved at intervals, the degradable dissolving sections are arranged on the filter membrane and can be automatically dissolved after a fixed time period, silt enters the drainage plate from positions where the dissolving sections are dissolved, and the core plate is automatically blocked, so that a drainage channel is blocked, the drainage channel can be dissolved and closed within a spe |
