Abstract

The invention belongs to the field of power equipment, and discloses an anti-permeating and anti-freezing concrete electric pole. The anti-permeating and anti-freezing concrete electric pole comprises the two parts of an upper part and a lower part, and is divided into a hollow pole and a solid pole. The top of the hollow pole is of a sealed structure, and a safety mark is arranged in the middle of the hollow pole; the hollow pole is of a concrete hollow structure, and connected with the solid pole through a connecting piece, a plurality of reserved holes are formed in the lower portion of the hollow pole so as to ensure that water entering the electric pole can be drained out timely; and the solid pole is composed of a rebar skeleton and a concrete layer wrapping the rebar skeleton, a steel sheet end head is arranged at the bottom of the solid pole, and the steel sheet end head is fixedly connected to the solid pole through a steel wire. The anti-permeating and anti-freezing concrete electric pole is higher in anti-bending and anti-pressing strength, good in anti-carbonization performance, anti-permeating performance and anti-freezing and anti-melting performance, and can serve as a substitute of common-used cement concrete electric poles.

Description

technical field [0001] The invention belongs to the field of electric equipment and relates to an anti-seepage and anti-freeze concrete electric pole. Background technique [0002] Electric poles are an important bridge for electricity, allowing electricity to be transmitted in all directions. With the continuous deepening and development of the current power system infrastructure construction, it is gradually understood that the harsh operating environment has put forward higher requirements for the mechanics and durability of transmission line towers. Concrete poles are the most commonly used poles. At present, the design strength of concrete poles is generally C40 and C50, and the raw materials are mainly traditional materials such as cement, gravel, sand, etc. Due to differences in worker operation errors and maintenance conditions, the actual strength is often lower and the durability is also limited. Without guarantee, the production process and performance of tradit...
