GROUND IMPROVEMENT APPARATUS AND GROUND IMPROVEMENT METHOD
To provide a ground improvement apparatus and a ground improvement method that can perform a ground improvement by means of machine agitation without making a construction machine installed on the ground large in size.SOLUTION: The ground improvement apparatus includes a rod unit 2, an agitation unit 3 that is supported by the rod unit 2 rotatably and that has an ejection port 33 ejecting a solidification material being supplied into the ground, an agitation power unit 4 that is attached to the rod unit 2 and that drives the agitation unit 3 rotationally by means of supplied power, and a reaction force unit 5 that is attached to the rod unit 2 and that ensures reaction force against the rotation of the agitation unit 3. The agitation unit 3 includes a shaft part 31 supported by the rod unit 2 rotatably and a plurality of agitation blades 32 extending radially from the shaft part 31. The reaction force unit 5 includes a cylindrical defining frame 51 covering the agitation unit 3 and a plate-like reaction force blade 53 attached outside the cylindrical defining frame 51.SELECTED DRAWING: Figure 1
【課題】地盤上に設置する施工機械を大型化することなく、機械攪拌による地盤改良を行うことができる地盤改良装置及び地盤改良方法を提供する。【解決手段】ロッド部２と、ロッド部２に回転可能に支持され、供給された固化材を地盤中に噴出させる噴出口３３を有する攪拌部３と、ロッド部２に取り付けられ、供給された動力によって攪拌部３を回転駆動させる攪拌動力部４と、ロッド部２に取り付けられ、攪拌部３の回転に対する反力を確保する反力部５とを備えている。攪拌部３は、ロッド部２に回転可能に支持された軸部３１と、軸部３１から放射状に延びる複数の攪拌翼３２とを備え、反力部５は、攪拌部３を覆う円筒状の画定枠５１と、画定枠５１の外側に取付けられた板状の反力翼５３とを備えている。【選択図】図１
