The invention discloses a reinforced sound isolation and heat insulation cement plate, and belongs to the field of building materials. The reinforced sound isolation and heat insulation cement plate comprises a cement mortar surface layer and a cement mortar inner layer, wherein the opposite inner sides of the cement mortar surface layer and the cement mortar inner layer are respectively connected with steel bar reinforcing layers, a polyurethane foam layer is arranged between the steel bar reinforcing layers, and a plurality of through holes in irregular distribution are arranged on the hard polyurethane foam layer. Through the arrangement of the double-layer steel bar reinforcing layer between the cement mortar surface layer and the cement mortar inner layer, the integral intensity is greatly improved, and the damage probability is reduced; the plurality of irregularly distributed through holes are formed in the hard polyurethane foam layer arranged between the steel bar reinforcing layers, the separation realized through the through holes on the basis of the sound isolation and heat insulation by the hard polyurethane foam layer, and the sound isolation and heat insulation effects are further improved.
