The invention discloses a method for constructing wear-resistant and crack-resistant hardened ground, which is applied to hardened ground of buildings such as modern industrial factory buildings, shopping malls, exhibition buildings, indoor parking lots, warehouses and the like. The method sequentially comprises the following steps of: brushing slurry on the surface of a base layer, namely watering to wet and clean the base layer and uniformly brushing a layer of 801 glue-doped cement slurry on the surface of the base layer; pouring, compacting and trowelling a polypropylene fiber concrete floor with the thickness of 50mm, removing bubbles and free water from the polypropylene fiber concrete by using a vacuum water absorption device, and removing laitance on the surface of the concrete after the concrete is initially set; laying a hardened wear-resistant layer and trowelling for 1 to 2 hours; calendaring by using a trowelling machine; and spreading a layer of BZK-15 surface liquid molded concrete curing agent to cure the ground. The hardened ground poured by the construction method has the characteristics of high durability, permeability resistance and crack resistance, and low construction cost.
