To perform an angular adjustment for a connection part where rods are connected to each other on an excavation rod without using drive power of a motor.SOLUTION: A ground excavation part 100 constituting a ground improvement device 10 comprises an excavation rod 110 in which multiple rods 120 are connected and that, while being pressed, an excavation auger 132 of a tip rod 130 rotates and excavates the ground G, and a changeover mechanism 140 that is provided on at least one of connection parts 150 where rods 120 are connected to each other and that changes the state of the device between a first state that a front side rod 120A of the connection part 150 is rotatable in a vertical plane relative to a rear side rod 120B, a second state that a front side rod 120A can rotate only in an upper direction in the vertical plane, and a third state that rotation is locked.SELECTED DRAWING: Figure 1
【課題】掘削ロッドにおけるロッド同士が接続された接続部の角度調整をモータの駆動力を用いることなく行う。【解決手段】地盤改良装置１０を構成する地盤掘削部１００は、複数本のロッド１２０が接続されて構成され押し込まれながら先端ロッド１３０の掘削オーガ１３２が回転して地盤Ｇを掘削する掘削ロッド１１０と、ロッド１２０同士が接続された接続部１５０の少なくとも一つに設けられ接続部１５０の前側のロッド１２０Ａが後側のロッド１２０Ｂに対して、鉛直面内で回転自在な第一状態と鉛直面内で上方向にのみ回転可能な第二状態と回転がロックされた第三状態とを切り替える切替機構１４０と、を備えている。【選択図】図１
