編）等が既に実施されていた。(Conventional technology) Probable contact oxidation is a phenomenon in which organic matter contained in water comes into contact with gravel and is oxidized, promoting the generation of microorganisms. The decomposition of pollutants by microorganisms, that is, the purification of water, occurs naturally. Therefore, attempts have been made to purify water by actively utilizing this catalytic oxidation. For example, attempts have been made to build embankments by depositing gravel on the river bed, or by depositing gravel separately. Attempt to install a septic tank (Showa 8)
0th Edition Insanuma White Paper P40. (edited by the Insanuma Environmental Foundation), etc. had already been implemented.
（発明が解決しようとする問題点）
ところで、この確聞接触酸化を効率的に行なわせるには
、有機物つまり水と礫との接触面積をできるだけ大きく
する必要があり、このため、従来、粒径の小さい礫を選
択するようにしていた。(Problem to be Solved by the Invention) By the way, in order to carry out this definite catalytic oxidation efficiently, it is necessary to make the contact area between the organic matter, that is, water, and the gravel as large as possible. I tried to select small stones.
しかしながら、上記川床に堤を構築する態様によれば、
礫自体が小粒であるため水圧を受けて流出し易く、流れ
の速い河川において鎖環を安定的に維持するのが困難で
あるという問題があった。特にこの堤の構築に際しては

および工費の増大をもたらすこととなっていた。また上
記浄化槽を設ける態様においても礫の流出を防ぐ特別の
浄化槽が必要で、前記同様に施工上の問題発生が避けら
ないところとなっていた。However, according to the aspect of constructing an embankment on the river bed,
Since the gravel itself is small, it is easily washed away by water pressure, and there is a problem in that it is difficult to maintain a stable chain in fast-flowing rivers. In particular, when constructing this embankment, it is desirable to use rubble from the viewpoint of construction efficiency, but due to the problems mentioned above, it is impossible to use rubble as is, and some kind of reinforcement is required, which delays the construction period. This would have resulted in an extension and an increase in construction costs. In addition, even in the case where a septic tank is provided, a special septic tank is required to prevent gravel from flowing out, and as described above, problems in construction are unavoidable.
本発明は、上記従来の問題点に鑑みてなされたもので、
破開接触酸化を再現し得る水浄化用コンクリートブロッ
クを提供することを目的とする。The present invention has been made in view of the above-mentioned conventional problems.
The purpose of the present invention is to provide a concrete block for water purification that can reproduce fracture catalytic oxidation.
（問題点を解決するための手段）
本発明に係るコンクリートブロックは、相互に連通して
表面に開口する小孔を多数設けた構成としたことを特徴
とする。(Means for Solving the Problems) A concrete block according to the present invention is characterized in that it has a structure in which a large number of small holes that communicate with each other and open on the surface are provided.
本発明において、上記小孔は三次元的に連通して設けら

は４０〜６０％程度とするのが望ましい。In the present invention, the small holes are provided in three-dimensional communication, allowing water to flow from any direction. The size and cross-sectional shape of the small pores are arbitrary, but in order to increase the contact area with water, it is desirable to make the diameter as small as possible and to have an irregular shape. It is desirable to set it to about 60%.

Fracture contact oxidation similar to natural stone can be reproduced in concrete blocks. Furthermore, the weight of the concrete itself provides sufficient resistance to water flow.

されている。In FIGS. 1 and 2, reference numeral 1 denotes a rectangular parallelepiped concrete block body with an uneven surface, and the block body 1 is provided with a large number of small holes 2, 2, etc. that open on the surface. . The small holes 2 include a hole group 2a that penetrates the block body 1 in the X direction, and a hole group 2a that also penetrates the block body 1 in the Y direction.
b, and a hole group 2C that also penetrates in the Z direction, and the block itself! They are interconnected within. Further, the block body l is formed to have a height IM, a width IN, and a length of about 2M, for example, and has small holes 2.
For example, the diameter is approximately 5 to 10 mm.

As shown in Fig. 3, a rod 5 with an oval cross section is prepared in advance.
, 5... are assembled three-dimensionally by penetrating them mutually, this assembly is set in a formwork (not shown), and after pouring concrete, the rod 5 is pulled out. The remains of the removal remain as small holes 2, and due to the assembly structure of the rods 5 passing through each other, the small holes 2 are communicated with each other.

るようになる。With this configuration, when the concrete block 1G is placed in a flow of water, the water flows vertically and horizontally through the hole groups 2a, 2b, and 2c, as shown by the arrows in Fig. 2, and during this time it comes into contact with the concrete surface. The organic matter in the water is oxidized and microorganisms are generated. In other words, fracture catalytic oxidation is reproduced within the concrete block 10, and microorganisms attached to the concrete skin decompose pollutants in the water, thereby purifying the water.

まり、その後河川等へ方流される。FIG. 4 shows an example of a purification facility using concrete blocks IO having the above configuration. In the same figure,
Reference numeral 11 denotes a bank formed in a U-shape, and a plurality of concrete blocks 10 are arranged in an inclined manner on both sides of the ring 11. The U-shaped opening side of the embankment 11 is the lower side.
A water channel 12 is provided at its upper end. There is also a pump room on the back side of Embankment 11! 3 is provided, and polluted water from, for example, a river or a lake is pumped into the waterway 12 of the chain ring 11. In this purification device, the polluted water overflowing from the water channel 12 first flows into the small hole 2 (Fig. 1) of the uppermost concrete block 10, and then sequentially flows into the lower concrete block 10. Contaminated water is purified by catalytic oxidation. The purified water then collects in the center of the dam 11 and is then flowed into a river or the like.
なお上記浄化施設において、コンクリートブロック１Ｇ

み重ねて各役向にプール１５を形成するようにするのが
望ましい。In addition, at the above purification facility, 1G concrete block
can be arranged in a stepwise manner as shown in FIG. In this case, it is preferable to stack concrete blocks in multiple stages at one step to form a pool 15 for each role.
これによって該プール１５内に一旦流下する水が溜まり
、コンクリートブロックの全体が水に浸漬されるように
なって、浄化効率がより向上する。As a result, the water that flows down once accumulates in the pool 15, and the entire concrete block is immersed in water, thereby further improving the purification efficiency.
また本コンクリートブロック１０は、上記浄化施設への
