This invention relates to the field of engineering construction technology and discloses a piling device for road traffic engineering construction, comprising a main body. When the piling machine retracts from its bottom output end, the protrusion retracts into the arc-shaped groove and pushes the rotating ring to rotate.

When the rotating ring converges, it contacts the side wall of the pile body and applies a thrust to correct it. This reduces the tendency for piles to tilt during piling due to incomplete verticality, which can cause angular errors between the pile and the piling machine. The device ensures the pile remains vertical during piling, improving the overall quality of piling in road construction.
