The invention relates to a multifunctional reinforced-tooth concrete canvas and belongs to the field of composite canvases. Packaging fiber cloth of the multifunctional reinforced-tooth concrete canvas is in closed flat tube shape, and a waterproof protective bottom layer is arranged below the packaging fiber cloth; a plurality of layers of divided tooth reinforced fiber cloth having dividing, reinforcing and toughening functions are arranged in the packaging fiber cloth and are filled with hydraulic cement dry-mixed mortar, thereby forming multiple layers of reinforced communicated concrete teeth and a top layer of reinforced communicated leveling teeth. The problem that fibers are unable to be stirred well is effectively solved; the outer packaging fiber cloth is of small-pore meshed fiber cloth; the divided tooth reinforced fiber cloth divided layer by layer is used to perform dividing; uniform distribution can be maintained in production, transportation and construction; the divided tooth reinforced fiber cloth has large voids regularly distributed, so that the reinforced communicated concrete teeth and the reinforced communicated leveling teeth are maximally reinforced, a spatial toughened lattice system is formed, stress performance is significantly improved, and construction quality is improved.
