PURPOSE:To increase the bearing capacity of the tip of a pile by inserting blocks and an expandible material into plural holes drilled in the peripheral side of the pile. CONSTITUTION:Blocks 1 and an expandible material 3 are inserted into the holes 11 of a custom-made pile 2, and the pile 2 is penetrated into the ground. The expandible material 3 absorbs moisture and expands by the hydrating reaction, thereby pushing out the blocks 1 into the ground. Since the blocks 1 are well penetrated into the ground, the bearing capacity of the tip portion of the pile 2 can be increased. |
