摘要：【課題】掘削土と結合材との固化混合物からなる円柱状改良体の内部に、結合材のみからなる芯体を形成する地盤改良工法において、掘削孔の底部から結合材が土壌中に流出するのを防ぎ、芯体を均整な形状に形成して、安定した支持力を得る。【解決手段】掘削孔40内に結合材を注入し、掘削土と結合材とを攪拌混合して未固化の混合物5を生成した後、掘削孔40の軸心部分に結合材を追加的に注入し、未固化の混合物5の内部に結合材のみからなる未固化の芯部6を柱状に形成して、それらを固化させることにより、固化混合物50からなる円柱状改良体の内部に結合材のみからなる芯体60を形成するに際し、掘削孔40の最底部に届かない位置に芯底蓋材3を配置して、芯底蓋材3よりも上方に未固化の芯部6を形成するための結合材を注入することで、芯体60を掘削孔40の最底部41よりも上方に離隔させて均整に形成する。【選択図】図4

摘要： PROBLEM TO BE SOLVED: To provide a ground improving agitation device for which the durable period of an agitation blade is made longer than before.SOLUTION: In the ground improving agitation device including a rotary shaft 11 to be rotated by a drive unit, an excavation blade provided on the distal end of the rotary shaft 11, and agitation blades 12 provided less on the distal end part side than the excavation blade, each agitation blade 12 is configured by fixing a planar member 122 arranged in the direction of pushing through a solidification material and excavated sediment to a blade body 121 in a round bar shape. Since the blade body 121 is in the round bar shape, agitation resistance is smaller than that of an agitation blade comprising planar members as before. Thus, even in the case of agitating the unit amount of excavated sediment, the drive unit of small output is sufficient. Also, the planar member 122 pushes through the solidification agent and the excavated sediment that are being agitated, and reduces loads applied to the blade body 121. Since the loads locally applied to the agitation blade 12 are reduced in such a manner, damages such as a break of the agitation blade 12 are prevented. Thus, the durable period of the agitation blade 12 is made longer than before.
摘要翻译：要解决的问题：提供一种改善搅拌装置，使搅拌叶片的耐久期比以前更长。解决方案：在包括由驱动单元旋转的旋转轴11的地面改善搅拌装置中，设置在旋转轴11的远端上的挖掘刀片和更少设置在远端部侧的搅拌叶片12 每个搅拌叶片12通过将沿着固化材料的推进方向布置的平面构件122固定在圆棒状的叶片体121上而构成。由于叶片体121为圆棒形状，因此如前所述，搅拌阻力小于包括平面部件的搅拌叶片的搅拌阻力。因此，即使在搅拌挖掘的沉积物的单位量的情况下，小输出的驱动单元就足够了。此外，平面构件122推动正在被搅动的凝固剂和被挖掘的沉积物，并且减小施加到叶片主体121的负载。由于局部施加到搅拌叶片12上的载荷以这种方式减小，防止了搅拌叶片12的断裂。因此，使搅拌叶片12的耐久期比以前更长。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a soil improvement agitation device which can make the output of a drive unit smaller than ever before at the agitation of excavated earth and sand of unit quantity.
SOLUTION: The ground improvement agitation device includes a rotary shaft 11, an excavation blade 14, an agitation rotor 12 formed in a round bar shape, and a rotor 17 for preventing rotation in concert with each other. The rotary shaft 11 is rotated by the drive unit, and the excavation blade 14 is provided on the tip of the rotary shaft 11. The agitation rotor 12 is provided in a position which is closer to the non tip side than the excavation blade 14 in a plurality of stages. The rotor 17 for preventing rotation in concert with each other is provided to the rotary shaft 11 with flexible rotation, and prevents rotation of the ground and the agitation rotor 12 in concert with each other. Since each of the agitation rotors 12 is formed in a round bar shape, it has smaller agitation resistance than a conventional agitation rotor constituted by a tabular member. Because of this, a low power drive unit is sufficient even for the agitation of the excavated earth and sand of unit quantity.
