Abstract
To provide a determination method and a determination support system of arrival at a support layer capable of determining more properly an arrival of a tubular pile such as a steel pipe pile at a support layer in an inner excavation pile method.SOLUTION: A determination support system 40 acquires a depth of a tip portion of a steel pipe pile (a tubular pile), an integral current value of an auger driving source 32 driving an earth auger 23, and an integral output value of a vibration driving source 37 driving a vibrator 24 and displays a first indicator that is an integral current value per depth and an indicator based on an integral output value per a depth on a display device 46. Thus, arrival of the steel pipe pile at a support layer can be determined based on a plurality of indicators.SELECTED DRAWING: Figure 2
