Zusammenfassung:The invention provides a high-strength anti-seepage and anti-freezing concrete electric pole. The electric pole comprises a reinforced framework and a concrete layer, wherein the reinforced framework comprises erection rings equidistantly-arranged in the vertical direction of the electric pole and longitudinal pre-stressed reinforcing bars wound by spiral ribs; a seal cover is arranged at the top end of the electric pole; each longitudinal pre-stressed reinforcing bar is shorter than the concrete layer coated outside the longitudinal pre-stressed reinforcing bar; the concrete layer at the bottom end of the electric rod is provided with a circular or square blind hole which is coaxial with the concrete layer and is filled with a corrosion-resistant material corresponding to each reinforcing bar. According to the concrete electric pole provided by the invention, the little ends of the reinforcing bars are protected in concrete and other corrosion-resistant materials in the blind holes, and the reinforcing bars are not exposed and sealed in the blind holes, so that reinforcing bars at the root of the concrete electric pole are not collided; as a protective layer is provided, corrosion cannot occur. The concrete of the concrete electric pole has the early-stage, middle-stage and later-stage strengths, so that the optimal performance of a cementitious material is achieved, and the optimal strength during the whole life cycle and durability are improved.
