A rigid alloy plastic bridge drain pipe comprises an embedded pipe body and a lower adapter; the lower end of the embedded pipe body is connected with the upper end of the lower adapter; a limit stand is arranged on the inner wall of the lower end of the embedded pipe body; a downstream seepage-proof eave is arranged on the edge of the limit stand; the upper end of the lower adapter is connected to the inner wall of the embedded pipe body on the outer side of the downstream seepage-proof eave through threads; a pitted surface layer is arranged on the outer wall of the embedded pipe body; outward seepage-proof concave-convex grooves are formed in the pitted surface layer; the embedded pipe body is made of rigid alloy plastic, and the rigid alloy plastic is formed in a manner that PC, PBT, PET and ABS are synthesized and are subjected to extrusion granulation at 250-350 DEG C and then injection-compression moulding by an injection molding machine die. The rigid alloy plastic bridge drain pipe has the advantages of being strong in antioxidant properties, corrosion-resistant, higher in mechanical strength, non-aging, free from toxin decomposition, acid-resistant and alkali-resistant, heat-resistant and weather-resistant, good in dimensional stability and impact resistance performance and high temperature-resistant and cold-resistant, and is adapted to diverse climates and severe environments.
