Laying system and method for salt prevention and reinforcement of salinized soil roadbed

The invention discloses a laying system for salt prevention and reinforcement of a salinized soil roadbed. The laying system comprises a bearing trolley platform system; the semi-rigid salt-proof isolation structure layer comprises a salinized soil roadbed, and a reinforcing structure, a semi-rigid base pavement cushion layer and a concrete pavement which are sequentially laid in the salinized soil roadbed from bottom to top, road shoulder cushion layers are laid on the two sides of the concrete pavement, and the upper surfaces of the road shoulder cushion layers are flush with the upper surface of the concrete pavement; the reinforcing structure comprises a salt-resistant protective layer, salt-resistant layer anchoring layers located at the two ends of the salt-resistant protective layer and permeation reinforcing layers distributed around the bottoms of the salt-resistant layer anchoring layers, the pavement cushion layer is laid on the salt-resistant protective layer, and the salt-resistant layer anchorin
