Description

technical field [0001] The invention relates to photovoltaic solar technology, in particular to a photovoltaic solar structural unit and a road surface construction method based on light-conducting concrete. Background technique [0002] Photovoltaic solar pavement power generation technology was introduced in the patent application 201410142523.X. This technical solution solves the problem of power generation and storage, but the top layer of the structure uses plexiglass to achieve the purpose of protection and light transmission, and there are the following shortcomings: First, The unit price of plexiglass is high, which leads to uneconomical cost of the structure as a whole; second, the friction coefficient of plexiglass material is small, and the anti-slip performance of the structure surface mainly depends on the depth of the structure, the anti-slip effect is not ideal, and it also has an adverse effect on the lighting performance . Therefore, choosing a suitable lig...

[0004] In order to achieve the purpose of using solar power on the road surface, light-guiding concrete can be used, but there are still several problems: (1) The problem of structural design, the existing light-guiding concrete is mostly used for wall lighting and art design; (2) The selection and arrangement of light-guiding materials. In order to improve the light transmittance of existing light-guiding concrete, the distance between optical fibers or resins used is mostly millimeter-level, which requires extremely high construction technology and high cost; (3) ) Cement mortar cannot meet the requirements of road surface strength and road performance
