The invention relates to the technical field of electric power. An anti-mistaken-digging underground with ultrasonic wave feedback locating comprises a cable body buried below the ground. The cable body is provided with a self-power-generating ultrasonic wave locating device upwards in a sleeved mode. The ultrasonic wave locating device comprises a communication module, a microprocessor system and a storage module for storing a cable position and parameter information. The communication module is connected with the microprocessor system which is connected with the storage module. The communication module comprises an ultrasonic wave emission device and an ultrasonic wave receiving device matched with the ultrasonic wave emission device. The storage module stores the position and identity recognition codes related to the parameter information. The ultrasonic wave locating device which does not need a power supply for power supplying is arranged on the cable body, during detecting, only a hand is needed for holding equipment for scanning, and whether a cable is buried below the ground in advance at a construction position can be known. If yes, the position and the cable information can be provided accurately. Accordingly, construction is convenient.
