Cement-soil stirring and bearing pile and formation method thereof
The invention belongs to the technical field of building, particularly relates to a cement-soil stirring and bearing pile and a formation method thereof and solves the technical problems of poor pulling resistance and poor pile body strength. The cement-soil stirring and bearing pile comprises a pile body made of cement and soil by solidification, the pile body is provided with at least one expansion portion protruding out of the pile body along the radial direction. The formation method includes arranging a plurality of drill pipes and whitewashing pipes according to that the axes are not on the same plane, wherein each drill pipe is provided with a drill bit at the end, the drill bits are boring drill bits with adjustable rotation radius, during drilling of the drill bits, rotation radius of the drill bits can be at least expanded at one time and rotation radius of the drill bits is larger than that of stirring blades. The pile foundation is good in stability, high in strength and high in pulling resistance and anti-bearing force.
