DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification channel which is suitable for use in a channel in which flowing water loses or is losing its self-purifying effect and which can restore the natural purification effect.

[0002]

2. Description of the Related Art Usually, rivers and waterways are provided with a self-cleaning action for cleaning dirt themselves. The self-cleaning action is a combination of physical action, chemical action and biological action. In Japan, drainage channels for irrigation are laid in paddy fields, but in the downstream area of such channels, domestic wastewater in the surrounding area flows in, the dirt gets worse year by year, and the self-cleaning function has stopped functioning. There are many examples.

[0003] Purification of water is carried out by the action of microorganisms attached to the waterways. The microorganisms need oxygen at this time, but when the soil is remarkable, the microorganisms increase and the consumption of oxygen increases. In the downstream area of the waterway, the supply of oxygen is low, and in many cases it is often used as a river of death or a drainage channel of death. In particular, in the case of a conventional water channel using a three-sided concrete upholstery or a U-shaped fume pipe, the water channel tends to be straightened, and the agitating action of water cannot be obtained because there are no irregularities on the side and bottom surfaces. In addition, plants do not grow in the water. These cannot expect the effect of promoting the dissolution of oxygen in the air. In addition, there are no stones or sand in the canals, so there is no flora that supplies oxygen to the water.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to provide a self-cleaning function to purify water even in a water channel similar to a conventional water channel formed by three-sided concrete upholstery or fume pipes. It is.

[0005]

According to the present invention, a partition plate 1 having a through hole 3 is fixed substantially parallel to a side wall of a water channel, and stones, earth and sand, etc. are interposed between the partition plate 1 and the side wall of the water channel. This was solved as a water channel in which a water purification section 8 was formed in a part of the water channel after being introduced.

[0011]

By introducing stones, earth and sand, etc. between the partition plate 1 having a hole and the side wall of the channel, a channel portion through which water flows into one channel and a purification section for purifying the water are formed. Water flowing through the water channel enters through the through hole of the partition plate 1 into the portion where the stone, the earth and sand, etc. are thrown. Since stone, earth and sand, etc. are filled between the partition plate 1 and the channel side wall, a porous water channel is formed, and microorganisms for purifying water can be propagated. At this time, if the stone has a neutralizing property such as limestone or a porous material such as lava or porous concrete, it is possible to neutralize acidic water, and the porous nature of aquatic Plants thrive.

The provision of the through-holes 3 in the partition plate 1 allows water to flow between the water channel side and the purifying section, thereby increasing the purifying ability.

The surface of the partition plate 1 is made of a stone 4 such as a fake stone or a main stone.
By embedding the above, it becomes possible to get closer to the natural scenery, and it becomes a multi-natural type waterway.

By providing a cut portion 5 at the bottom of the partition plate 1 to communicate left and right, a living space is provided for living organisms such as fish living in the water, and water circulation is improved. A plurality of cut parts 5 are provided, and some of them are provided on the bottom plate 12.

As can be seen from these figures, a substantially U-shaped block frame 1 is formed by both side plates 11 and 11 serving as side walls of a water channel and a bottom plate 12.
The partition plate 1 is fixed substantially parallel to the water channel side wall 11 made of zero. In this example, lava 6 is charged between the partition plate 1 and the side wall of the water channel. As a result, the water channel section 7 and the purification section 8 are formed in the block body 10.

To fix the partition plate 1, the two screw bolts 14 inserted into the bolt insertion holes of the one side plate 11 of the block body 10 are screwed into the female screw structure insert 13 buried at the top and bottom of the partition plate 1. and, a structure that has entered into a side plate 11 side in the nut.

Since the above-mentioned lava 6 and porous concrete are porous, they easily adhere to aquatic plants and microorganisms and contribute to water purification. When the water quality is acidic, it is preferable to use limestone. By neutralizing the limestone, the dead canal can be revived.

The details of the partition plate 1 are shown in FIGS. 5 to 7. The partition plate 1 has through holes 3 from the bottom to the top.
Is provided. FIG. 5 is a front view of the partition plate 1 as viewed from the water channel side, FIG. 6 is a side view, and FIG. Because of this through-hole, water flowing through the water channel enters the purification section 8 side, and if the algae or stones attached to the stones inside are limestone, they react with them to neutralize and purify.

Further, the cut portion 5 is provided at the bottom of the partition plate 1 so that the left and right sides can communicate with each other, whereby water and aquatic organisms enter and exit the purification portion 8 from the water channel portion 7. The central cut portion is fitted to a rib 15 provided on the bottom plate 12 and perpendicular to the direction of water flow.

The bottom plate 12 is formed by the ribs 15 and the embankments 16 at both ends.
