The utility model discloses a concrete pile structure used for the marine environment and belongs to the technical field of concrete corrosion prevention engineering. In the structure, the surface of a concrete pile is smooth, and a paint coating, a corrosion prevention belt and a protecting armor are sequentially arranged on the outer side of the concrete pile from inside to outside. According to the concrete pile structure, the outer surface of the foundation pile is smooth, it can be ensured that winding of the corrosion prevention belt is tightly attached to the pile, and the corrosion prevention effect is improved; secondly, as epoxy primer is adopted for carrying out closing treatment on the surface of the pile, corrosive media can be effectively prevented from permeating into the protecting armor and corroding the pile, and then the sealing effect is improved; thirdly, as the protecting armor is made of a high-tenacity material, damage to the protecting armor due to impact of external force is effectively reduced, and the service life of the whole structure is prolonged.
