MANUFACTURING METHOD TO CONVERT INORGANIC SLUDGE INTO RECYCLED SOIL
To provide a method for inexpensively producing recycled soil of a required particle size, without the need for the conventional work of depositing and raising solidified sludge on a flat ground and loosening it with a backhoe, etc., and further without using a particle size separator/crusher for the recycled soil.SOLUTION: Sludge, cement-based solidifying material, and water are put into a granulating and solidifying processing machine 1 of a work vehicle C in a required weight ratio, an uncured and fluid solidified product of the granulating and solidifying processing machine 1 is carried by the work vehicle C to a sloping ground 2, the solidified material is dropped from above an upper end of the sloping ground 2 by a sloping discharge conveyor 13, and the solidified product KM is slid down and agitated on a surface of the slope 2, so that recycled soil with a small particle size is classified above the slope and recycled soil with a large particle size is classified and deposited on a lower side of the slope, and recycled soil is prepared in layers on the surface of the slope depending on a size of the particle.SELECTED DRAWING: Figure 4
【課題】 従来の汚泥の固化処理物の平地で盛り上げてバックホウ等でよりほぐし作業を行うことなく、更に再生土に粒度分離装置・破砕装置を使用せずに所要の粒度の再生土を安価に製造できる方法を提供する。【解決手段】 汚泥とセメント系固化材と水とを所要重量比率で作業車Ｃの造粒固化処理機１に投入し、同造粒固化処理機１の未硬化で流動性のある状態の固化処理物を作業車Ｃで傾斜地２へ運んで、その固化処理物を傾斜排出コンベヤ１３によって傾斜地２の上端の上方から落下させ、傾斜地２の斜面で固化処理物ＫＭを滑落させて撹拌させることで、粒度の小さい再生土を斜面の上方に及び粒度の大きい再生土は斜面下方側に分級させて堆積して、傾斜面に粒度の大小によって層状に再生土を作製する。【選択図】図４
