The present invention provides a method for constructing a pile in a riprap layer, which includes a boring step for boring the ground with a casing (100) and an air hammer (200); a hollow wall stabilization step for stabilizing a hollow wall (1) by spraying a stabilizer liquid (a) in order for a mixture of the stabilizer liquid (a) and slime to adhere to the hollow wall (1) while the ground is bored by the air hammer; a pile installation step for installing a pile (10) in the bored hole after boring the ground to the predetermined depth; and a stabilization releasing step for releasing the stabilization of the hollow wall (1) by supplying a decomposition liquid (b) to the stabilized hollow wall (1). Therefore, the present invention efficiently forms a bored hole in the riprap layer. |
