Description of the Related Art In order to effectively use waste molten slag such as sewage sludge molten slag, crushed waste molten slag is press-molded into blocks and fired to form a water-permeable block for road paving. Technology is being developed. However, since the crushed material of the molten slag has an indeterminate shape, the back side and the central portion of the crushed material have poor tightness when pressed in the mold and tend to cause variations in density. Further, when the formed block is fired, the firing gas is difficult to flow to the lower surface of the block, so that the firing state is different between the upper portion and the lower portion of the block, and the block tends to be deformed.

特徴とするものである。SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, provides a back surface of a water-permeable block body made of waste molten slag with a concave portion through which gas passes during firing from at least one end. It is characterized by being provided so as to penetrate the other end.

成されているが、１本であってもよい。The present invention will be described in more detail with reference to the embodiments shown in the drawings. In the first embodiment shown in FIG. 1, 1 is a water permeable block body made of crushed sewage sludge molten slag, and 2 is a recess formed on the back surface thereof. This recess 2 is for passing gas during firing,
The water-permeable block body 1 is provided so as to penetrate from one end to the other end. In the embodiment, two recesses 2 are formed by crossing each other, but one recess may be formed.

ク本体１の垂直断面積の10〜30％程度の断面積を持たせ

ましい。The size of the concave portion 2 is not particularly limited, but if it is too large, the strength of the water permeable block is impaired, and if it is too small, the gas flow during firing becomes poor, so the vertical cross-sectional area of the water permeable block body 1 is reduced. It is preferable to have a cross-sectional area of about 10 to 30%, and the depth is preferably 10 mm or more.

The shape of the cross section can be variously changed. Further, as shown in FIG. 5, a surface layer 3 made of fine-grain waste molten slag may be formed on the surface of the water permeable block body 1. However, in any case, the concave portion 2 needs to penetrate from one end of the water permeable block body 1 to the other end and open at the end face.

る。Since the water-permeable block of the present invention thus constructed has the concave portion 2 on the back surface, when the waste molten slag crushed material is put into the molding die and press-formed, the back side is also pressed. Effectively acts to improve the tightness, and a molded product having a uniform density can be obtained throughout. Further, when this molded body is placed on a baking table and fired in a furnace, the firing gas easily reaches the central portion of the back surface of the molded body through the recesses 2 and makes the firing state of the upper and lower portions uniform. be able to.

透水機能が従来のものよりも向上することとなる。As described above, according to the present invention, the density and the burning state can be made uniform, but since the concave portion 2 on the back surface acts as a drainage path for the moisture passing through the water-permeable block body 1, After laying in the water-permeable block, the water-permeable function as a water-permeable block will be improved as compared with the conventional one.

There is an advantage that it can be a structure.

業の発展に寄与するところは極めて大きいものである。As described above in detail, the water permeable block of the present invention is provided with a recess on the back surface of the water permeable block body, through which gas passes during firing, from one end to the other. As a result, the block has a uniform density and the firing states of the upper portion and the lower portion are made uniform. In addition, the water-permeable block of the present invention has the advantages that the concave portion functions as a water discharge path to enhance the water-permeable function, and that when it is used on a wall surface or the like, it can be a stable structure. Therefore, the present invention, as a water-permeable block that solves the conventional problems, contributes greatly to industrial development.
