The invention belongs to the technical field of medium conveying pipelines, and relates to a double-layer abrasion resisting grid bent pipe for concrete conveying. The double-layer abrasion resisting grid bent pipe comprises an outer pipe with a certain curvature. An inner container pipe is arranged in the outer pipe in a matched manner. Filling space formed by the inner container pipe and the outer pipe is internally provided with filler. Each of the two ends of the outer pipe is provided with a flange. End plugs are fixedly arranged on the inner walls of the flanges. The two ends of the inner container pipe abut against and make contact with the corresponding end plugs. Strengthening ribs are arranged on the outer surface of the inner container pipe. A plurality of pouring ports are formed in one side of the inner container pipe. The bent pipe producing and manufacturing cost is low, and the service life is long.
