The present invention relates to an excavation device for a foundation pile and a method for reinforcing soil using the same. The excavation device for a foundation pile inserts a foundation pile into the ground to reinforce soil, and comprises: a hollow body to accommodate an end portion of one side of the pile through an opened surface thereof; a mounting panel mounted or separated to close the other surface of the body; a mounting member mounted on one side of the pile penetrating the mounting panel to be accommodated in the body; an excavation wing formed on an outer surface of the body in a screw thread shape to excavate the ground while rotating and moving forwards; an excavation unit having a rotary key outwardly protruding from a position on an upper portion of the body which is out of a range in which the excavation wing is formed; a rotary body having a stopping groove which is formed on an inner surface thereof, accommodates the pile, and is mounted on the rotary key to rotate the excavation unit on which the pile is fixed; and a rotational unit having a power source linked and installed to rotate the rotary body. The foundation pile is inserted into the ground to maximally avoid a contact between a side surface of an excavated groove and the pile to prevent a reduction in strength and damage by a crack or torsional stress which can be formed on the pile. |
