摘要： PROBLEM TO BE SOLVED: To provide an excavating torque reduced press-in method of rotary press-in steel pipe pile capable of efficiently rotating and pressing a rotary press-in steel pipe pile at a low torque. SOLUTION: In this method, the rotary press-in steel pipe pile 1 opened in the lower end part is rotated and pressed into ground 3 in the state where it is held by a steel pipe pile rotary press-in device 2. When the torque applied to the steel pipe rotary press-in device 2 by a blocked pipe inner soil 4 penetrating into the rotary press-in steel pipe pile 1 and acting to block the steel pipe pile lower part is raised to cause the excavating torque shortage of a construction device or reach a preset set torque or more, the blocked pipe internal soil 4 in the rotary press-in steel pipe pile 1 is discharged to reduce the excavating torque of the rotary press-in steel pipe pile 1.
