The invention relates to a GFRC nonmetal sound barrier production line. The production line comprises a control system, a platform automatic conveying system, a material automatic distribution system,a distribution molding system, an automatic stacking conveying system, a maintaining system, an automatic demolding system and a platform shuttle bus automatic return system; and the production linecomprises the following steps of material distribution, release agent spraying, platform conveying, material distribution molding, neatening stacking, sound barrier maintaining, sucking disc demoldingand sound barrier finished product delivering. The GFRC nonmetal sound barrier production line is reasonable in structure design, assembly line operation is adopted for replacing the past manner thatmanual operation by a worker is completely adopted, the working environment of the worker is improved, the labor intensity of the worker is greatly reduced, the production cost is reduced, conversionof production from the manual manner to mechanization and intelligence is achieved; and the production efficiency is improved, the product quality is guaranteed, and the need of large-batch production of GFRC nonmetal sound barriers for high-speed trains is met.
