PURPOSE: A steel pipe driving method using a high-pressure injection rod in a jet grouting pile method of construction is provided to drive a steel pipe easily and to improve constructability by removing unnecessary processes. CONSTITUTION: The steel pipe driving method using a high-pressure injection rod in a jet grouting pile method of construction comprises the steps of: placing a high-pressure injection rod(1) to the planned depth; forming a pile by rotating the high-pressure injection rod(1) from the base, jetting grout under high pressure and drawing simultaneously; before the pile is hardened, placing the high-pressure injection rod(1) in the pile to be installed on the base of the pile; placing a steel pipe to the base of the pile by fitting in the high-pressure injection rod(1); and jetting grout and drawing the high-pressure injection rod(1) from the steel pipe.
