Light-transmitting concrete slab manufacturing device and preparation method

The invention discloses a light-transmitting concrete slab manufacturing device and a preparation method, and belongs to the technical field of building materials. The light-transmitting concrete slabmanufacturing device comprises a U-shaped supporting box body, 2n porous rod pieces arranged on the two sides of the U-shaped supporting box body and m optical fibers connected to the 2n porous rod pieces, wherein n is an integer larger than or equal to 1, and m is an integer larger than or equal to 1; each porous rod piece comprises a circular ring rod and end connecting rods arranged at the twoends of the circular ring rod, every two adjacent circular ring rods are detachably connected, and a plurality of limiting holes are uniformly formed in each circular ring rod and used for allowing the corresponding optical fibers to penetrate through; and each optical fiber sequentially penetrates through the 2n circular ring rods. According to the light-transmitting concrete slab manufacturingdevice and the preparation
