Cement mixing pile and construction method
The invention relates to the technical field of soft soil foundation treatment, in particular to a cement mixing pile and a construction method.The cement mixing pile comprises a stand pipe body, and the outer side of the stand pipe body is connected with a cement mixing body; the outer convex block is connected with the cement stirring body; the arc-shaped sealing strip and the supporting vertical pipe body are coaxially arranged, a containing cavity is formed in the supporting vertical pipe body, the arc-shaped sealing strip is rotationally connected with the supporting vertical pipe body and can block the containing cavity, and the arc-shaped sealing strip penetrates through the cement stirring body and is connected with the outer protruding block; the control unit is installed on the stand pipe body and used for controlling the rotating angle of the arc-shaped sealing strip. The device has the beneficial effects that the rotating angle of the arc-shaped sealing strip is conveniently controlled through the control unit, then the sealing performance of the supporting stand pipe body is kept when the supporting stand pipe body is put down through the arc-shaped sealing strip, the resistance during putting down is reduced, the arc-shaped sealing strip stretches out during concrete pouring, and the sealing effect is good. The possibility that the outer convex block is separated from the cement stirring body when the cement stirring pile is loaded is reduced, and the use reliability of the cement stirring pile is improved.
本申请涉及软弱土地基处理技术领域，尤其涉及一种水泥搅拌桩及施工方法，包括支立管体，支立管体外侧连接有水泥搅拌体；外凸块与水泥搅拌体连接；弧形封闭条与支立管体同轴设置，支立管体上开设有容纳腔，弧形封闭条与支立管体转动连接，并能够封堵容纳腔，且弧形封闭条穿过水泥搅拌体与外凸块连接；控制单元安装于支立管体上，用于控制弧形封闭条的转动角度；本申请具有通过控制单元便于控制弧形封闭条的转动角度，进而实现弧形封闭条在支立管体下放时保持支立管体的封闭性，并且减少下放时的阻力，并在混凝土浇筑时实现弧形封闭条的伸出，降低受载荷时外凸块从水泥搅拌体上脱离的可能性，提高水泥搅拌桩的使用可靠度的效果。
