| 81 | Drill and method for removing and drilling in earth | JP2004274512 | 2004-09-22 | JP2005098096A | 2005-04-14 | STOETZER ERWIN EMIL |
| PROBLEM TO BE SOLVED: To solve the problem that an excavated hole with a strong wall cannot be formed in a specific earth condition because earth and sand fall from the wall of the excavated hole before a filling material is filled in the completed excavated hole. SOLUTION: An earth removal head 40 is removably attached on the bottom end of a drill rod 20. By this, the earth in the circumference is removed when the head is made to penetrate the earth. Upon the arrival at a specified depth, the drill rod 20 is removed from the earth removal head 40. The bottom end of the rod 20 is designed as an earth removal part 30 with a width wider than that of the drill rod part adjacent to it. Because the earth removal part 30 has a wider width, the earth and sand falling from above at the time of extraction is removed toward the wall of the excavated hole.

| PURPOSE:To prevent the return of excavated soil by a method in which a circular expanding blade is pivotally attached to the periphery of the screw blade, and the circular expanding blade is housed when the auger is inversely turned by a stopper and a coupler but automatically expanded when the auger is turned normally. CONSTITUTION:An expanding blade 6 of a height smaller than the pitch of the screw blade 2 of a screw auger for on-site piling work is pivotally attached to the periphery of the screw blade 2 in such a way that it can expanded when the auger is turned normally but shrunk when the auger is turned inversely. The cross section of the blade 6 is a circular. A stopper 8 is provided to near the periphery of the blade 2, and a hook 12 fixed to a rod 13 vertically moving in parallel with the auger shaft 1 is coupled to the tip of the blade 6. When the auger is turned inversely, the blade 6 is shrunk by the stopper 8 and the hook 12, but when the auger is turned normally, the blade is expanded by means of the resistance of soil by releasing the hook 12. The return of excavated soil in the expanded diameter portion can thus be prevented. | ||||||
