方法が普通である。(Prior art) In order to manufacture a water-permeable multilayer block using the above-mentioned sewage sludge molten slag as a raw material, the raw material for the surface layer, which is a mixture of pulverized slag with a binder and a colorant, is placed at the bottom of a mold. The usual method is to fill the block to a uniform thickness, then uniformly fill the slag raw material for the main body part that does not contain a colorant, and obtain a multilayer block with a colored surface layer by vibration pressure molding. It is.

場合にはきわめて多数枚の底板が必要となる欠点がある
。However, blocks made from slag have poor shape retention immediately after molding, so it is difficult to remove them from the mold while remaining on the molding bottom plate. The method used was to lift it up, take it out, and send it to the drying process along with the bottom plate. However, this case has the disadvantage that a very large number of bottom plates are required.
そこでブロックを底板とともに成形型から取り出したう
え、人手によりブロックから底板を注意深（外して成形
型に戻す方法も取られているが、人手に頼るために能率
が上がらないという問題があった。One method was to remove the block along with the bottom plate from the mold, then carefully remove the bottom plate from the block by hand and return it to the mold, but this method was not efficient due to relying on manual labor.

とするものである。(Means for Solving the Problems) The present invention, which has been completed to solve the above problems, has a surface layer with high shape retention that is pre-molded using the same or different molds and is positioned at the bottom of the mold. The upper part is filled with slag raw material to form a multilayer block with a main body portion that has relatively low shape retention, and this multilayer block is lifted from the mold and released using the surface layer that has high shape retention. It is characterized by this.

(2) is a heat plate provided at the bottom of the preform (1), and (3) is a heat punch provided above the preform (1), and the slag raw material for the surface layer is heated by these heat plates. It is heated and pressed by a plate (2) and a heat punch (3), and is formed into a surface layer (4). This surface N(4) is made of slag raw material, but because it is hot pressed, the binder is sufficiently solidified.
The surface layer (4) has high shape retention.

is taken out from inside the mold (5). The multilayer block (7) molded according to the present invention has a surface layer (4) with high shape retention.
Since the main body portion (6) with low shape retention is supported on top of the body, it is possible to easily take it out onto a container or the like using the surface layer (4). Further, the transfer work can be easily mechanized by dividing the surface layer (4) into chunks.

ことができる。(Effects of the Invention) As explained above, according to the present invention, a surface layer with high shape retention, which has been preformed by the same or different molds, is placed at the bottom of the mold! The upper part of the block is filled with slag raw material to form a multilayer block, so the multilayer block, which has a main body part with poor shape retention, can be easily lifted out of the mold by using the surface layer with high shape retention. It can be released from the mold. Therefore, according to the present invention, there is no need to send the molded body with the bottom plate placed thereon to the drying process as in the conventional case, and there is no need to use a large number of bottom plates. Further, according to the present invention, since the multilayer block can be taken out without manual intervention, the manufacturing efficiency of the multilayer block can be improved. Furthermore, according to the invention, the surface layer can also be obtained as a purchased item, in which case the manufacturing equipment for the surface layer (formulation, cross-wiring,
This eliminates the need for tanks, molding equipment, etc., and the equipment can be simplified.
