The invention relates to an application of aggregate chips in concrete pipe pile prefabrication. The application is characterized by being application of the aggregate chips as concrete filling aggregates in pipe pile prefabrication components, wherein the adding amount of the aggregate chips accounts for 20%-30% of the total mass of the concrete filling fine aggregates. The application has the beneficial effects that: compared with the prior art, the aggregate chips are used to replace components, in a concrete pipe pile, of river sand. The problem that the river sand is in resource shortage can be relieved, damages on the environment by over-exploitation are avoided, and the pollution problem caused by the aggregate chips further can be solved; meanwhile, the aggregate chips replace part of the river sand, so that the grain composition of the filling aggregates is optimized, the working performances of concrete are improved, and the performances and tensile strength of the pipe pile are improved; and the ma
