High-strength anti-seepage and anti-freezing concrete electric pole

Abstract

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.

Description

technical field [0001] The invention relates to a concrete electric pole, in particular to a high-strength anti-seepage and antifreeze concrete electric pole. Background technique [0002] Based on the national energy distribution, one of the ways to solve energy contradictions is to establish thermal power, hydropower, wind power and solar power bases in energy centers, and then transmit electric energy with large capacity and long distances. The overhead line poles of transmission lines, from the original wooden poles to the square solid concrete poles in 1924 to the steel poles widely used in high-speed rail today, among which the concrete poles have changed from the first square solid concrete poles in 1924 to In 1938, centrifugal electric poles were produced, and then in the 1950s and 1960s, the most widely used centrifugal annular electric poles and prestressed electric poles were produced successively. [0003] With the continuous deepening and development of the cur...
