Basement base plane moisture-proof structure

A basement base plane moisture-proof structure comprises lower-layer cement, reinforcing ribs are arranged in the lower-layer cement in a penetrating mode, a moisture-proof film is arranged on the lower-layer cement, at least one evenly-spaced fixing support is arranged on the moisture-proof film, and prefabricated reinforced concrete plates are arranged on the fixing supports. Upper-layer cementis laid on the prefabricated reinforced concrete slab, and a high polymer modified asphalt layer is laid on the upper-layer cement. According to the utility model, the reinforcing ribs distributed ina staggered manner are arranged in the lower cement layer, so that the strength of the lower cement layer can be improved; the damp-proof film is arranged on the lower-layer cement, so that moisture in foundation soil can be effectively prevented from evaporating into basement space, and the damp-proof effect of the ground is improved; the basement base plane is raised in an overhead manner through the fixing bracket, so t
