Compression-resistant and heat-resistant waterproof and drainage board

The utility model belongs to the technical field of tunnel waterproof and drainage equipment, and particularly relates to a pressure-resistant and heat-resistant waterproof and drainage board. Comprising a pressure-resistant layer, a heat-resistant layer and a waterproof layer which are sequentially arranged from top to bottom, and the pressure-resistant layer, the heat-resistant layer and the waterproof layer are pressed and shaped through a negative-pressure shaping roller. According to the technical scheme, in order to improve the compression resistance and heat resistance of a waterproof board in the prior art, a waterproof and drainage board made of a single material in the prior art is improved, and the waterproof and drainage board is designed into a composite board with a plurality of different functional layers. Wherein the top plate is mainly used for improving the overall hardness of the composite plate, so that the compressive strength of the composite plate is improved; the heat-resistant layer o
