The present invention relates to a method for constructing a helical pile while carrying out grouting that can introduce a grouting material directly to the disturbed ground around the helical pile which is rotated and penetrated through the ground, thereby utilizing the helical pile as a pile for structure foundation. The method includes the steps of: rotating and penetrating a helical pile by a helical pile constructing device, the helical pile having a hollow shaft provided with a protective cap provided on the outer periphery surface to protect a grouting hole against pressurized injection of the grouting material, and a coupler for connecting the shafts by bolts; introducing the grouting material into the shaft by the helical pile constructing device in order for the grouting material to be injected directly through the grouting holes into the ground disturbed by rotation wings of the helical pile, and curing the grouting material; and installing an upper pressing plate onto a head of the helical pile, the upper pressing plate having a vertical pipe fastened to the head of the shaft by bolts, and a pressing plate formed on the outer peripheral surface of the vertical pipe. |
