Abstract

PROBLEM TO BE SOLVED: To make it possible to improve the water quality in purification of rivers, sewage treatment, etc., without destroying the ecology of living things by providing the surface of coarse-grained concrete contg. ceramics with a permeable resin layer into which water purifying materials are incorporated. SOLUTION: This concrete production A exhibits natural stone-like appearance and is formed by using the coarse-grained concrete 1 contg. the ceramics on its inner side and forming the permeable resin layer 3 formed by solidifying the water purifying materials 2, such as charcoal, ceramics, shells and pebbles with a permeable resin on its surface. This permeable layer 3 maintains contact with the coarse-grained concrete 1 and, therefore, water infiltrates the layer from the rear surface as well or the water can pass through the rear surface. A good water draining property is thus obtd. The purification of the rivers and the sewage treatment are executed without impairing the natural scenes if such natural stone-like concrete products are laid on the river bed or installed by putting the products into wire cylinders, grid frames, etc. In addition, the purification of the water is made possible by the filtration and sterilization effect of the water purifying materials 2.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a concrete product for improving water quality in rivers and the like.

[0002]

2. Description of the Related Art Conventionally, charcoal, ceramics, etc. have been used for purification of rivers, treatment of sewage, improvement of water quality, etc. The method of use is to put charcoal of 2-5 cm in a net or bag,
Heavi stones were placed in the shape of a stream in the river.

Further, the surface of a concrete block for revetment is applied to the river, and a concrete block such as Mitsutomi, a legal frame, etc. is piled up as a pseudo stone, thereby improving the water quality of the river. Was there.

[0004]

[Problems to be Solved by the Invention] When charcoal or the like is installed in a conventional river as described above, it will flow out in case of heavy rain, and it will have to be installed again, and the appearance is also disorderly and natural. Has the drawback of spoiling the landscape.

Further, a concrete block for use as a revetment and having its surface made into a pseudo stone has no problem in landscape, but it does not have a water purifying effect and, on the contrary, causes destruction of the ecology of living things.

[0006] In view of the above points, the present invention is to provide a concrete product for improving water quality, which can improve water quality such as purification of rivers and treatment of sewage without destroying the ecology of living things.

[0007]

According to the present invention, since a permeable resin layer mixed with a water purification material is provided on the surface of coarse-grained concrete containing ceramics, ceramics increase the strength of concrete and coarse-grained concrete is used as a concrete product. Since water penetrates into the inside, the drainage is improved, and bacteria, moss, etc. are easily attached and the growth is also improved. Also, since the water purification material is mixed in the permeable resin layer on the surface,
Water is purified by bactericidal action and sewage is also treated.

Since the present invention uses charcoal, ceramics, shells, etc. as a water purification material, water is purified by being filtered and sterilized, and acid rain is also converted into alkaline water.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, A is a concrete product of the present invention, which has a natural stone-like appearance, in which a coarse-grained concrete 1 containing ceramics is used, and on the surface thereof, charcoal, ceramics, shells, peas, etc. A permeable resin layer 3 is formed by solidifying the water purification material 2 of 1. with a permeable resin.

FIG. 2 shows the concrete product A of the present invention in the form of a rectangular block, in which a permeable resin layer 3 mixed with a water purification material 2 is formed on one side of a coarse-grained concrete 1 containing ceramics.

FIG. 3 shows the concrete product A of the present invention used in a concrete block 4 for revetment. A water purifying material 2 is mixed in the front surface of the concrete block 4 for revetment through the coarse-grained concrete 1 containing ceramics. The resin layer 3 is formed.

FIG. 4 shows the concrete product A of the present invention used in a concrete block 4 for revetment. The water purifying material 2 is mixed in the front surface of the concrete block 4 for revetment through the coarse-grained concrete 1 containing ceramics. Although the resin layer 3 is provided, the transparent resin layer 3 is irregular and formed in a pseudo-stone pattern. With this shape, the surface area of the permeable resin layer 3 can be increased.

[0013]

EFFECTS OF THE INVENTION According to the present invention, since the permeable resin layer on the surface is in contact with the coarse-grained concrete, water can infiltrate from the back side or water can pass through to the back side, resulting in good drainage. . If natural stone-like concrete products are laid on the riverbed or placed in a gabion basket, a lattice frame, etc., the natural landscape can be purified and river purification and sewage treatment can be performed. In addition, charcoal, ceramics, which are water purification materials,
Since shells and the like are mixed in the permeable resin layer, the water is purified by filtration and bactericidal action, which is suitable for breeding fish and fireflies, and also enables good growth of bacteria, moss, aquatic plants, etc. It is a useful invention that can contribute to the improvement of water quality without destroying the ecology.
