The invention discloses a broken pile remedying method. According to the broken pile remedying method, a new pile structure is constructed based on the broken pile so as to improve properties of the original pile. The broken pile remedying method includes setting a reinforcement cage inside the original pile by lifting, pouring concrete into the original pile, driving a steel casing onto the outside of the original pile, setting a reinforcement cage by lifting and then pouring concrete in an interlayer formed between the original pile and the steel casing. The broken pile remedying method has the advantages of high integrity, high strength, low manufacturing cost and low influence to the surroundings.
