The invention provides a special-shaped honeycomb plate and an image-combining processing technique thereof, aiming at carrying out computer lofting. When a plate piece is horizontally placed, a top layer plate and a bottom layer plate are cut; the cut top layer plate and the cut bottom layer plate are compounded with a honeycomb-type tubular supporting piece to form the honeycomb plate; a honeycomb is vertically cut, certain position is reserved at the cutting rim, the reserved position is plugged by a plugging plate, and then seamless covering is carried out by the gluing technique; finally, each processed honeycomb is combined and spliced to form a needed image. The side cutting surface of the processed honeycomb is combined with the adjacent plate piece to carry out imaging; in addition, either the entire closely-spliced imaging or spaced imaging among the plate pieces can be carried out. The invention has the following advantages: the processing method is simple and convenient; the processed honeycomb plate is novel as well as light, is convenient for installation, has strong pressure resisting capability, and can clearly, truly as well as beautifully show the needed image.
