GROUND IMPROVEMENT AGITATION DEVICE
PROBLEM TO BE SOLVED: To provide a ground improvement agitation device for executing a ground improvement capable of securing a sure improvement diameter and capable of securing homogeneity of an improvement body, to the alluvial viscous soil ground or the alluvial sandy soil ground.SOLUTION: A rod 2 is provided with a first agitation blade 4, a second agitation blade 5 provided on the tip side of the rod 2 on the first agitation blade 4 and having the same length as the first agitation blade 4 and a third agitation blade 6 provided so as to cross at an angle of 90° with the second agitation blade 5 and having the length shorter than the second agitation blade 5. The tip of the third agitation blade 6 is provided with a nozzle 8 for injecting a hardener.SELECTED DRAWING: Figure 1
【課題】沖積粘性土地盤又は沖積砂質土地盤に対し、確実な改良径の確保及び改良体の均質性の確保を可能とした地盤改良を行う地盤改良攪拌装置を提供する。【解決手段】ロッド2には、第1の攪拌翼4と、第1の攪拌翼4に関してロッド2の先端側に設けられるとともに第1の攪拌翼4と同じ長さを有する第2の攪拌翼5と、第2の攪拌翼5に対して90°の角度をなして交差するように設けられるとともに第2の攪拌翼5よりも短い長さを有する第3の攪拌翼6とが設けられている。第3の攪拌翼6の先端には、硬化材が噴射されるノズル8が設けられている。【選択図】図1
