Manufacturing method for prefabricated pile rod

The invention relates to the technical field of prefabricated piles, and especially relates to a manufacturing method for a prefabricated pile rod. The manufacturing method for the prefabricated pilerod comprises the following steps: assembling a sunken empty cavity forming structure member and a mechanical connection structure member at the two ends of a reinforcement cage of the prefabricated pile rod separately, and detaching the sunken empty cavity forming structure member after concrete pouring. According to the manufacturing method for the prefabricated pile rod, after the reinforcementcage of the prefabricated pile rod is weaved, the sunken empty cavity forming structure member and the mechanical connection structure member are assembled at the two ends of the reinforcement cage of the prefabricated pile rod separately, an original reinforcement cage production process and equipment for a prefabricated pile are not influenced, the obtained prefabricated pile product completelyrealizes the purpose that
