Concrete solid square pile

The utility model discloses a concrete solid square pile, which relates to the technical field of concrete square piles, and comprises a square pile core, a limiting support rod is arranged on the outer side of the square pile core, support mechanisms are arranged on the outer side of the limiting support rod, the support mechanisms are arranged at the corners of the square pile core, and stabilizing mechanisms are arranged between the support mechanisms. Supporting mechanisms are arranged at the positions, corresponding to the limiting supporting rods, of the ends, facing the inner side, of the stabilizing mechanisms, stability of the square pile core is maintained through the limiting supporting rods, stability of the limiting supporting rods is kept through the stabilizing mechanisms and the supporting mechanisms between the support mechanisms on the outer side of the square pile core, and stability of the whole square pile is kept; meanwhile, when the concrete solid square pile is used, a one-way locking
