ROTARY NOZZLE, GROUND IMPROVEMENT APPARATUS AND GROUND IMPROVEMENT METHOD USING THE ROTARY NOZZLE
PROBLEM TO BE SOLVED: To provide a ground improvement apparatus capable of widening a drilled hole range and an improvement range of a ground.SOLUTION: In a ground improvement apparatus 10, which performs drilling and improvement of a ground 8 by injecting, into the ground 8, fluid with high pressure from an injection nozzle provided on a movable part 18, a lifting casing 18 as a movable part is provided with a stretchable body 20 that has a fluid passage in which the fluid flows inside and that stretches in a horizontal direction. On the tip of this stretchable body 20, a rotary nozzle 40 that rotates due to reaction force of the injection force of the fluid is provided so that the stretchable 20 is stretchable by fluid pressure of the fluid injected from the rotary nozzle 40 with high pressure.SELECTED DRAWING: Figure 1
【課題】地盤の削孔範囲及び改良範囲を広くできる地盤改良装置を提供する。【解決手段】地盤８中に可動部１８に設けられた噴射ノズルから流体を高圧噴射させて地盤８の削孔と改良を行う地盤改良装置１０において、可動部としての昇降ケーシング１８に、流体が流通する流体通路を内部に有して水平方向に伸縮する伸縮体２０を設け、この伸縮体２０の先端に流体の噴射力の反力により回転する回転ノズル４０を設け、伸縮体２０を回転ノズル４０より高圧噴射される流体の流体圧で伸長自在した。【選択図】図１
