HIGH PRESSURE JET AGITATION DEVICE FOR GROUND IMPROVEMENT AND GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a high pressure jet agitation device for ground improvement capable of establishing a ground improvement body having excellent uniformity even on any of improvement strength and an improvement diameter.SOLUTION: In a high pressure jet agitation device for a ground improvement having a rod 1 having in a tip part an upper side injection nozzle 2 and a lower side injection nozzle 3 arranged at an interval in the vertical direction, and in the high pressure jet agitation device for the ground improvement, a distance between the upper side injection nozzle 2 and the lower side injection nozzle 3 coincides with an integral multiple of one time or more of the pull-up step length of the rod 1. A cutting liquid 4 is injected from the upper side injection nozzle 2, and solidification material slurry 5 is also injected from the lower side injection nozzle 3.SELECTED DRAWING: Figure 1
【課題】改良強度および改良径のいずれについても優れた均一性を有する地盤改良体を造成することができる地盤改良用高圧噴射撹拌装置を提供する。【解決手段】鉛直方向に間隔を置いて配設された上側噴射ノズル２および下側噴射ノズル３を先端部分に備えたロッド１を有する地盤改良用高圧噴射撹拌装置であって、上側噴射ノズル２と下側噴射ノズル３の間の距離が、ロッド１の引上げステップ長の１倍以上の整数倍と一致する、地盤改良用高圧噴射撹拌装置。上側噴射ノズル２から切削液４を噴射させ、かつ、下側噴射ノズル３から固化材スラリー５を噴射させる。【選択図】図１
