The invention discloses a screw-in type environment-friendly steel
pipe pile with tip blades and a construction method. The screw-in type environment-friendly steel
pipe pile comprises a steel
pipe pile body, a
pile cap fixed to the steel pipe pile body and a
spinning driving device driving the steel pipe pile body to rotate downwards, and the
pile cap is installed at the pile back position of the steel pipe pile body and driven by the
spinning driving device; a tip blade is mounted at the pile
tip position of the steel pipe pile, covers the pile
tip position of the steel pipe pile, and comprises two semi-doughnut-shaped
steel plates; the two semi-doughnut-shaped
steel plates are arranged on the periphery of the steel pipe pile in a V shape; the
steel plates with the semi-doughnut-shaped tip blades are arranged on the periphery of the steel pipe pile and welded in a V-shaped intersection mode, so that a wider stress surface can be formed when the pile tip enters a soil layer, the pressure of a soil body is dispersed, the soil body is effectively broken through through the gradual rotary
cutting effect, the penetrating power of the pile is improved, and the construction efficiency is improved. And the situation that the construction speed is reduced or the pile body deflects due to the fact that large resistance occurs when the pile tip of the steel pipe pile makes contact with a hard soil layer is avoided.
