Polygonal cement-soil stirring pile and formation method thereof
The invention belongs to the technical field of building, relates to a polygonal cement-soil stirring pile and a formation method thereof, and solves the technical problems in the prior art that the pulling resistance is poor and the pile body strength is poor. The polygonal cement-soil stirring pile comprises a pile body formed by solidifying cement and soil, wherein the pile body is composed of multiple pile bodies attached to one another; the cross section of the pile body comprises multiple arc-shaped angles; the number of the pile bodies is not smaller than that of the arc-shaped angles; the axial leads of the multiple pile bodies are not on the same plane and are parallel to one another; the formation method comprises the following steps: multiple drill pipes and multiple spouting pipes are not distributed and arrayed on the same plane according to the axial leads, drill bits are arranged at the end parts of the drill pipes, the multiple drill pipes drill underground simultaneously, during drilling, the stirring blades of the multiple drill pipes are not on the same plane and the multiple spouting pipes spout simultaneously, when the drill pipes drill in a set depth, the drill pipes and the spouting pipes lift towards the ground simultaneously, and the spouting pipes continuously spout during the lifting process. According to the invention, the pile foundation stability is excellent, and the pulling resistance and the bearing capacity resistance are high.
