spiral pile

Spiral ground piles are mostly used in the construction process of "end-bearing pile" structure and "friction pile" structure, and are more widely used in the construction of various ground piles, ground anchors and random structure ground piles. The working principle of the spiral pile is the same as that of the screw. It uses the lever balance condition of the thread. The thread expansion is a small and long inclined plane, which is easier to drive into the ground.
