Abstract

PURPOSE: To give a high resistance against a horizontal force by providing an expanded diameter part at the upper end of an existing pile erected in the ground.
CONSTITUTION: At the head part of an existing pile 3, a cylindrical diameter- expanding auger 11 having an inside diameter slightly larger than the outside diameter of the existing pile 3, the periphery of which is provided with a spiral screw 10, is provided concentrically with the existing pile 3. The diameter-expanding auger 11 is turned, the ground around the existing pile 3 is dug down to a given depth, and then while discharging concrete from the tip of the auger 11, the auger 11 is turned and drawn up. Thus, concrete 4 with an expanded diameter part 5 is constructed around the existing pile 3 over a given depth from the head part.
