Device for stirring foundation treatment pile in cooperation with rotary drilling machine and stirring method
The device comprises the rotary drilling machine, a center stirring shaft inserted into the soil environment is arranged at the lower end of the rotary drilling machine, a slurry inlet pipe for injecting cement slurry is connected into the center stirring shaft, and a drill bit is arranged at the end, inserted into the soil, of the center stirring shaft. The lower end of the rotary drilling machine is provided with a stirring device corresponding to the central stirring shaft, the stirring device and the central rotating shaft are connected through a gearbox and rotate together, the stirring device stirs soil uniformly, and the slurry inlet pipe injects cement slurry into the stirring device and stirs the cement slurry along with the soil under the action of the stirring device. The center stirring shaft drives the side wall rotating cutters to stir soil on the outer side, when the center stirring shaft rotates, the inner rotating cutters rotating in the opposite direction of the center stirring shaft stir the soil, the two sets of rotating cutters rotating in the opposite directions enable the soil to be stirred more evenly, and the two sets of rotating cutters rotating in the opposite directions generate relative rotating force at the common position of the rotating cutters. The stirring is more uniform.
本发明涉及一种配合旋挖机进行地基处理桩搅拌的装置及搅拌方法，包括旋挖机，旋挖机下端设置有插入土壤环境的中心搅拌轴，中心搅拌轴内连接有注入水泥浆的进浆管，中心搅拌轴插入土壤的端部设置有钻头，旋挖机下端对应中心搅拌轴设置有搅拌装置，搅拌装置与中心旋转轴通过齿轮箱连接并共同转动，搅拌装置将土壤搅拌均匀，进浆管将水泥浆注入搅拌装置内并在搅拌装置的作用下随土壤搅拌。通过中心搅拌轴带动侧壁旋转刀对于外侧土壤的搅拌，中心搅拌轴转动时与其相反方向转动的内旋转刀的搅拌，两组相反方向转动的旋转刀使土壤搅拌更加均匀，两组相反方向转动的旋转刀在其共同部位产生相对的旋转力，使搅拌更加均匀。
