Method for manufacturing multi-layer solid-wood compound floor

The invention provides a method for manufacturing a multi-layer solid-wood compound floor. The multi-layer solid-wood compound floor comprises a base material layer, a facing layer arranged above thebase material layer and a balancing bottom layer arranged below the base material layer. A compound rubber plate layer is arranged between the facing layer and the base material layer, a plurality ofinverted V-shaped grooves are formed in the bottom face of the base material layer, and a damping rubber mat layer is arranged between the base material layer and the balancing bottom layer; and the surface of the damping rubber mat layer is in a raised saw tooth shape, the raised saw tooth shape is tightly attached to the inverted V-shaped grooves formed in the bottom face of the base material layer, a plurality of irregular honeycomb through holes are distributed in the damping rubber mat layer, and a plurality of transversely arranged water guiding micro-holes are formed in the balancing bottom layer.
