Abstract

The invention belongs to the field of lightning protection materials and particularly relates to a lightning protection foundation in electric power, transportation, communication, aviation and otherfields and a preparation method of assistants. The technical scheme includes that the lightening protection foundation is formed by metal components and concrete; the concrete is composed of, by weight, 80-150 parts of cement, 90-180 parts of sand, 10-40 parts of carbon fiber and 5-20 parts of the assistants. By the arrangement, discharge of lightening current is facilitated, the lightning currentis evenly distributed in the foundation, local impact is not produced, so that the foundation is long in service life, good in lightning protection effect, high in integral strength and resistant toshock and distortion; the lightning protection foundation applicable to manufacturing of facilities and equipment of electric towers, bridges, railways, high-speed rails, airports, signal towers, chimneys and the like is widely applicable.

Description

technical field [0001] The invention belongs to the field of lightning protection materials, and in particular relates to a lightning protection foundation widely used in the fields of electric power, transportation, communication, aviation, etc., as well as the auxiliary agent used and its preparation method. It can be used as the lightning protection basis for facilities and equipment such as electric towers, bridges, railways, high-speed rails, airports, signal towers, and chimneys. Background technique [0002] Electricity, transportation, aviation, communications, construction and other infrastructures are mostly vulnerable to lightning disasters. For example, electric towers, poles, and street lights in power facilities, bridges, railways, especially high-speed rail in transportation facilities, signal towers, transmission towers, antennas in communication facilities, and chimneys in building facilities. These facilities and equipment are mostly set in the wilderness ...
