A device that measures the time difference from projection to reflection of the ultrasonic sensor, calculates the tip position of the tremie tube based on the time difference, and compares this calculated value with a preset finite range value to determine whether the calculated value is A tremie pipe construction management device comprising: a control device that raises the tremie pipe to the upper limit of the finite range value when the value becomes substantially the same as the lower limit of the finite range value.
