<p>According to the present invention, a boring apparatus is coupled to a drilling machine to bore a ground through a rotation thereof. The boring apparatus comprises a core tube, a slime collecting tank, and a slime removing unit. A rod connected to the drilling machine extends in a longitudinal direction, and receives power to be rotated. The core tube is coupled to the rod to be rotated together with the rod. A beat for drilling is formed on a lower side of the core tube, and storage space for receiving a drilling core is formed inside the core tube. A slime collecting tank is installed in an upper side of the core tube, and allows the slime, which is discharged outside the core tube and floats, to be stored therein. A slime removing unit receives compressed air from one side thereof, and discharges the compressed air to the other side thereof. Also, the slime removing unit generates a pressure difference inside, absorbing the slime collected in the slime collecting water tank, and discharges the slime together with the compressed air to the exterior. The core tube has a double-pipe structure and includes a first pipe, which is formed inside and has an injecting nozzle, and a second pipe, which is arranged on the first pipe and forms the storage space formed therein. The injecting nozzle discharges the slime generated when the ground is drilled by injecting with high pressure and water supplied from an exterior through the rod to the outside of the core tube.</p> |
