Stone paving structure capable of preventing alkali efflorescence and paving construction method thereof

According to the stone paving structure capable of preventing alkali efflorescence and the paving construction method of the stone paving structure capable of preventing alkali efflorescence, stone is installed on the surface of a paving base layer in a dry hanging mode through a back hanging structure, the stone is prevented from making direct contact with the paving base layer, meanwhile, a seam connecting piece is embedded in a seam between the stone, and the seam is blocked through the seam connecting piece; the paving base layer is arranged between the stone and the paving base layer, external moisture is prevented from entering the space between the stone and the paving base layer, a capillary water absorption assembly is further filled in the mounting gap between the stone and the paving base layer, moisture seeping from the stone and the paving base layer is rapidly absorbed and discharged through the capillary water absorption assembly, and then the moisture content between the stone and the paving b
