Method for manufacturing CFRP bar recycled concrete electric pole

Abstract

The invention belongs to the technical field of power transmission equipment, and discloses a method for manufacturing a CFRP bar recycled concrete electric pole. The method includes the following steps that (1) an outer tube template and an inner tube template of the electric pole are manufactured; (2) a CFRP bar is used for manufacturing an inner frame body of the electric pole, the inner framebody comprises an inner steel hoop, a vertical main bar, and a spiral mesh tube; (3) a CFRP cloth is wound and adhered to the surface of the outer side of the inner frame body in the circumferential direction by using structural adhesive, and a roller is used for multiple times of rolling in the winding direction of the CFRP cloth; (4) the well-adhered inner frame body of the CFRP cloth is placedbetween the outer tube template and the inner tube template, recycled concrete is poured between the outer tube template and the inner tube template, at the same time, the top of the electric pole iscapped with the recycled concrete, and the template is dissembled when the strength of the recycled concrete reaches 80% or above the design strength. According to the electric pole manufactured by the method, the structural strength is high, the weight is light, the occurrence of transverse and vertical cracks in the electric pole can be effectively reduced, and the service life of the electric pole is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission equipment, and in particular relates to a method for manufacturing a CFRP-reinforced recycled concrete electric pole. Background technique [0002] With the rapid development of my country's social economy, ultra-high voltage transmission lines continue to popularize, the scale of power grid construction continues to expand, and the civil engineering industry has also developed in an all-round way in my country. For ultra-high voltage transmission lines, the safety and reliability of power grids are directly related to national economic construction and social stability. In recent years, power grid construction projects have continuously become the focus of the strategic layout of national resources, and more economical, rapid and efficient construction of power grid projects has become an urgent need of this era. As one of the most widely used materials in the field of civil e...

[0004] Chinese patent CN201310386370.9 discloses a plastic utility pole. The utility model pole adopts a combined pole body assembly structure, which requires less investment in transportation and erection, and saves costs. However, the strength and wind resistance of the utility pole are insufficient, and the strength is particularly Low, frequent replacement, waste of manpower and material resources

In addition, Chinese patent CN201520698949.3 discloses a new type of utility pole. By adopting a technical solution, each main reinforcement group is equipped with four main reinforcements of different lengths to improve the structural strength of the steel skeleton layer and ensure that the structure of each length of the steel skeleton layer maintains Stable, although the structural stability of the steel skeleton layer is greatly improved, but the construction process is more complicated, and ideal pouring is difficult
