Zusammenfassung:The invention discloses a UHPC (Ultra High Performance Concrete) reinforced pile foundation and a reinforcing method thereof. The reinforcing method comprises the following steps: S1, manufacturing a circular steel casing; s2, the first pile casing and the second pile casing are assembled into a circular steel pile casing, and the circular steel pile casing is statically pressed outside the pile foundation; s3, the area between the pile foundation and the circular steel casing is washed, so that a cavity is formed between the pile foundation and the circular steel casing, and the concrete aggregate is exposed out of the pile foundation; s4, a circular reinforcement cage is manufactured, and the circular reinforcement cage is placed in a cavity between the pile foundation and the circular steel casing; and S5, pouring UHPC (Ultra High Performance Concrete) by taking the circular steel casing as a template. The circular steel casing is arranged outside the pile foundation, flushing and desilting are carried out
