The invention discloses a piled-up plastic honeycomb and a manufacture method for the same. The method comprises the steps that a single-row double-sided honeycomb component which is composed of a pair of V-shaped double-sided connected cell arrays and is equipped with ribbon holes is manufactured by an injection moulding technology; the components are successively piled up in a line direction or a row direction and are fastened by ribbons, so that the double-sided honeycomb which is symmetric in two sides, closely adjacent and equipped with hexagon-shaped cells with V-shaped included angles can be formed; and a honeycomb frame is added to peripheries of the honeycomb, so that the piled-up plastic honeycomb is formed. The honeycomb and the method disclosed by the invention have the beneficial effects that the single-row double-sided honeycomb component has a small projected area and a simple structure and can be shaped by injection moulding easily, so that a cell depth and a wall thickness of the piled-up plastic honeycomb which is formed through piling up are closer to the cell depth and the wall thickness of a bee honeycomb. In this way, the technical problem in the prior art that a deep-cell and thin-wall plastic honeycomb cannot be made through injection moulding can be solved. The piled-up plastic honeycomb has the advantages that duration spent by bees on making a honeycomb can be shortened; and the plastic honeycomb can be stored for a long time and can be used repeatedly.
