PURPOSE:To obtain a pile having a high frictional force by a method in which a pit of almost the same diameter as a pile to be driven is drilled, a hardener is injected into the pit, and a pile is driven into the pit before the hardener hardens. CONSTITUTION:A pit 2 of almost the same diameter as a pile 7 to be driven is dug out in the ground by an earth auger. Cement mortar M is packed into the pit 2, and the pile 7 is driven into the pit 2 before the mortar M hardens. Since the mortar M is pressed into the ground against the pressure of the pit wall, the effect of the friction of the pile 7 can be enhanced. |
