GROUND RESTORATION AUGER AND GROUND RESTORATION METHOD
To provide a ground restoration auger and a restoration method for sufficiently compacting inside a hole and the surrounding ground in a short time, while preventing fall of a side face of the hole during ground restoration.SOLUTION: A ground restoration auger 10 has a shaft 11 rotatable at least in the first rotation direction 17 around a rotation axis 16, a spiral conveying part 12 for conveying ground restoration materials downward from an upper end of the shaft 11 following rotation of the shaft 11 in the first rotation direction 17, and one or more protrusions 13 fixed to the spiral conveying part 12. The protrusion 13 protrudes from the spiral conveying part 12 in the direction separating from the rotation axis 16, and has an inclined plane 31 positioned at a front side of the protrusion 13 in the first rotation direction 17. The inclined plane 31 has an inclined plane inner edge part 41 near to the rotation axis 16 and an inclined plane outer edge part 42 separated from the rotation axis 16. The inclined plane inner edge part 41 is positioned before the inclined plane outer edge part 42 in the first rotation direction 17.SELECTED DRAWING: Figure 9
【課題】地盤復旧中に穴の側面の崩落を防ぎながら、長い時間をかけずに穴の内部及び周辺地盤を十分に締め固めること。【解決手段】地盤復旧オーガー１０は、回転軸１６の周りで少なくとも第１の回転方向１７に回転可能なシャフト１１と、第１の回転方向１７におけるシャフト１１の回転に伴ってシャフト１１の上端から下端に向けて地盤復旧材料を搬送するための螺旋搬送部１２と、螺旋搬送部１２に固定された１つ以上の突起１３とを備える。突起１３が、回転軸１６から離れる方向に螺旋搬送部１２から突出しており、突起１３が、第１の回転方向１７において突起１３の前側に位置する傾斜面３１を備え、傾斜面３１が、回転軸１６に近い傾斜面内縁部４１と回転軸１６から遠い傾斜面外縁部４２とを備え、第１の回転方向１７において傾斜面内縁部４１が傾斜面外縁部４２より前方に位置している。【選択図】図９
