Abstract
PURPOSE: To manufacture a septic tank provided with reinforcing ribs protruded entirely around the outer periphery by one process, by rotating a cylindrical mold provided with grooves along the peripheral direction, forming the molding material layer on the inner face of the mold and filling the grooves with filler, further laminating molding material upon it.
CONSTITUTION: A molding material layer 1 is formed on the entire inner periphery by delivering molding material on the inner periphery of a cylindrical mold A which is provided with grooves 11 along the peripheral direction entirely around the inner periphery and is rotated. Then, filler 13 is filled in the grooves 11 around the entire periphery and the molding material layer 2 is again laminated on the entire periphery of the cylindrical mold A. In this way the septic tank provided with the reinforcing ribs protruded entirely around the outer periphery can be manufactured by one process.
