Light-transmitting concrete construction process based on 3D printing

The invention provides a light-transmitting concrete construction technology based on 3D printing. The light-transmitting concrete construction technology comprises the following steps that a light guide body grid is prepared, and concrete for 3D printing is prepared. The columnar light-transmitting materials are arranged into a light guide body grid, and cross points are fixed; spraying an alkali-resistant coating on the surface of the light guide grid, airing and then carrying out surface treatment; concrete 3D printing and light guide body grid arrangement are carried out, and light guide body grids are printed layer by layer and arranged layer by layer; and the printed concrete surface is subjected to curing treatment, then surface finishing is conducted, and finally the needed light-transmitting concrete member is obtained. According to the method, 1, the light guide bodies are printed layer by layer and arranged layer by layer, so that the influence of overhigh density of the light guide materials on th
