The invention discloses a device for monitoring soil plug lifting height of a prestressed pipe pile in hydrostatic process. The device comprises a measure instrument, a fixed disc, a multiturn potentiometer, a synchronous wheel, a synchronous belt, a first counterweight and a second counterweight. The fixed disc is provided with fixing legs, the multiturn potentiometer is fixed on the fixed disc, the synchronous wheel is inlayed on the multiturn potentiometer, the synchronous belt is twined on the synchronous wheel, the first counterweight and the second counterweight are respectively arranged at the two ends of the synchronous belt, the weight of the first counterweight is greater than the weight of the second counterweight, and the measure instrument is connected with the multiturn potentiometer. By the device, the change of the soil plug lifting height of the prestressed pipe pile in the hydrostatic process can be accurately monitored in real time. The device is simple in structure and clever in design, lo
