Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purification block for purifying water quality by floating it on the edge of a water such as a lake or a pond where there is little water flow.

[0002]

2. Description of the Related Art Conventionally, a spherical block made of spherical porous concrete has been used for water purification in lakes and marshes.

[0003]

Since the conventional spherical block has a specific gravity heavier than water, it has been sunk in the bottom of the water.
Since the flow of water is small in lakes and reservoirs, the efficiency of purification was remarkably poor because the water stagnated especially at the bottom of the water. The present invention has been made in order to provide a purification block with high purification efficiency for use in lakes and reservoirs where water flows little.

[0004]

SUMMARY OF THE INVENTION The present invention is a porous concrete purification block characterized in that a buoyancy generator such as foamed plastic is provided inside and the specific gravity of the whole is 1 or less.

[0005]

[Function] Porous concrete is a porous concrete produced by remarkably increasing the coarse aggregate ratio as compared with normal concrete, and it has water permeability and water purifying property due to the growth of microorganisms in the pores. Are known. Permeability is used, for example, to maintain the groundwater level by infiltrating rainwater into the ground by manufacturing a flat plate for sidewalks with porous concrete. The water purification property is used by sprinkling spheres made of porous concrete on the bottom of river beds and lakes.

Since the purification block of the present invention is made of porous concrete, it has the above-mentioned water purification property. Also,
Since the buoyancy generator such as foamed plastic is arranged inside and the specific gravity of the whole is set to 1 or less, the purification block of the present invention floats on the water surface. Since waves are generated near the water surface due to the influence of wind, the water purification efficiency is much improved compared to the case where the water purification block is installed on the stagnant water bottom.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments. FIG. 1 is a perspective view of a purification block 1 as one embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is an explanatory view of a usage state.

The purification block 1 shown in the figure is made of porous concrete, and has a large number of hemispherical projections 2 formed on one surface of a flat plate-shaped main body. The projections 2 are advantageous in purification efficiency because the contact area between concrete and water is large, and the water flow flows along the hemispherical surface to prevent turbulent flow and does not adversely affect the microorganisms in the concrete holes. It is provided in. A buoyancy generator 3 made of expanded polystyrene is disposed inside, and the specific gravity of the whole is 1 or less, that is, it floats in water. The buoyancy generator 3 is shown in FIG.
The left side is thick and the right side is thin. Therefore, the purification block 1 is light on the left side in FIG.
The right side is heavy. Therefore, this purification block 1
When floated on the water, the left side is exposed above the surface of the water, and the right side is tilted to float under the surface of the water.

As shown in FIG. 3, when the purification block 1 is installed at the water's edge, it tilts and floats, and since the right side contacts the bottom, it is possible to prevent the purification block 1 from being washed away by wind or the like. . If a large number of purification blocks are connected and installed along the water's edge, even better results can be obtained.

EFFECT OF THE INVENTION The purification block of the present invention is made of porous concrete, has a water purification action, and is excellent in purification efficiency because it floats on the water surface. In addition, like a continuous block,
Even if the water level changes, even if the water level changes, it is always near the water surface due to the effect of buoyancy, so the maximum purification efficiency can be increased with a small installation area.
