The present invention provides a boring device (100) for forming a bulb and a foundation construction method using the same. The boring device (100) for forming the bulb includes a central pipe (110) in which a fluid path of a soil solidification agent in the vertical direction of a core part and a plurality of side pipes (120) extended towards the side of the central pipe (110), wherein an injection port (121) of the soil solidification agent is formed on an outer wall and the fluid path of the soil solidification agent is formed on the core part. The boring device (100) for forming the bulb is characterized by boring the ground with the rotation of the central pipe (110) and the side pipes (120) and forming a bulb unit (10) with a mixture of the soil and the soil solidification agent. The present invention improves workability by boring the ground and charging solidification soil. |
