Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter block used for a drainage channel, an irrigation channel, and the like. In addition, the present invention relates to a lining block for revetment used in river revetment work.

[0002]

2. Description of the Related Art Gutter blocks are widely used for construction of drainage channels, irrigation channels, and the like. Normally, the gutter block is made of reinforced concrete and has a U-shaped or U-shaped cross section. The inner wall surface of the gutter block is a smooth surface so as to reduce running water resistance.

[0003] In general, rivers are usually covered with concrete blocks (bank protection lining blocks) for flood control purposes.

[0004]

By the way, the gutter constructed using the above-mentioned gutter block is durable and can smoothly discharge drainage and irrigation water. It does not always provide a good living environment for aquatic insects, fish and other vertebrates.

For example, before the above-mentioned gutter block was used, fireflies (genji fireflies, heike fireflies, etc.) and dragonflies, which were often found in irrigation canals flowing through urban areas, cannot be found recently. The current situation is increasing. In addition, fish and other vertebrates such as aquatic insects and medaka have been remarkably reduced.

[0006] Such a decrease in aquatic insects and the like is due to the fact that a large amount of domestic wastewater and livestock excreta are washed into the gutter and the water quality is deteriorated, and microorganisms (plankton, etc.) and algae serving as baits are reduced. It is thought to be due to difficulty in breeding.

[0007] In particular, regarding the drastic decrease of fireflies, in addition to the above-mentioned causes, snails (such as Kawaina), which are bait of firefly larvae, are difficult to grow and propagate in the concrete gutter. It has been pointed out that larvae are unlikely to crawl on the inner wall surface of the concrete gutter block and consequently end their lives without becoming adults on land. The inner wall surface of the concrete gutter block is unlikely to crawl even for frogs and dragonflies.

[0008] The same can be said for a riverbank covered with concrete blocks.

[0009] Here, in today's world where protection of the natural environment is required on a global scale, it is first necessary to improve the environment of familiar rivers and drainage channels.

An object of the present invention is to provide a gutter block and a seawall lining block capable of forming an environment suitable for aquatic insects such as fireflies, microorganisms, algae, fish, and other vertebrates. Is to do.

[0011]

According to a first aspect of the present invention, there is provided a main body for forming a water channel, wherein at least a portion of the inner wall of the main body has water absorption / water retention and the height is equal to the height of the main body. A gutter block, comprising the porous material described above, wherein the porous material absorbs water from a portion in contact with water, contains water up to an upper end, and is capable of retaining the water. It is.

In the case of this invention, the porous material attached to a part (or the whole) of the inner wall of the main body contains water up to the upper end as well as the part immersed in water. Microorganisms and algae serving as baits of Kawanaina adhere to the surface of the porous material and easily grow and propagate. Also, dissolved oxygen in water increases due to photosynthesis of algae. Therefore, fireflies larvae feeding on the snails are more likely to inhabit.

[0013] Further, since the porous material absorbs water up to the upper end and retains it inside, the portion that goes out of the water surface is also humid and has little difference from the underwater temperature. Moreover, since many fine holes are formed in the surface of the porous material, larvae of fireflies and dragonflies are likely to catch on. Therefore, larvae of fireflies are likely to crawl.

From the above, firefly larvae and the like are likely to inhabit, and the probability of going up to land and becoming adults is increased.

[0015] Further, the large number of pores of the above-mentioned porous material are used as a habitat for microorganisms (such as beneficial bacteria and plankton which decompose organic substances and the like) and proliferate, so that harmful substances in the water are decomposed and the water is purified. In addition, foods such as fish and other vertebrates will be provided in abundance. Also, dissolved oxygen in water increases due to photosynthesis of algae.

Accordingly, an environment suitable for inhabiting aquatic insects such as fireflies, microorganisms, algae, fish, and other vertebrates can be formed.

According to a second aspect of the present invention, the porous material is formed of a plurality of porous ceramic plates vertically arranged, and is in close contact with each end face of an adjacent porous ceramic plate. This is a gutter block provided with a filling means for transferring moisture between the porous ceramic plates.

According to this invention, even when it is difficult to manufacture a porous material having a large surface area (for example, a ceramic plate) from the viewpoint of processing technology or economy, a plurality of porous ceramic plates are filled through the filling means. By connecting, a porous material having a large surface area capable of absorbing water up to the upper end and retaining the water therein can be easily formed. Therefore, claim 1
In addition to achieving the same operation and effect as in the case of the described invention, even when the main body is tall, a porous material having a height equal to or higher than the main body can be more easily formed.

According to a third aspect of the present invention, there is provided a water replenishing means, one part of which is buried in the soil around the main body and the other part of which is in contact with the porous material and which can replenish moisture in the soil to the porous material. It is a side groove block provided.

In this invention, even when the water is dried or the flow of water is artificially stopped, the porous material is replenished with moisture in the soil, so that microorganisms, algae, snails and the like can be dried. The probability of surviving until is resolved can be increased. Therefore, an environment more suitable for inhabiting aquatic insects such as fireflies, microorganisms, algae, fish, and other vertebrates can be formed.

According to a fourth aspect of the present invention, there is provided a main body for covering a riverbank, and at least a part of the surface of the main body is provided with a porous material having water absorption / water retention and a height equal to or higher than the main body. An embankment lining block, wherein the porous material absorbs water from a portion where the porous material comes into contact with water and contains water up to an upper end thereof, and can retain the water.

In the case of this invention, since the porous material attached to a part (or the whole) of the inner wall of the main body contains water up to the upper end, microorganisms and algae which feed on snails (such as Kawaina) can be obtained. Easy to grow and breed. Also, dissolved oxygen in water increases due to photosynthesis of algae. Therefore, fireflies larvae or the like that feed on the snails are likely to inhabit.

Further, in the above-mentioned porous material, a portion which goes outside from the water surface is also humid, and the difference from the underwater temperature is small.
Further, since the porous material has a large number of fine pores formed on the surface thereof, larvae of fireflies and larvae of dragonflies are likely to catch up. Therefore, larvae of fireflies are likely to crawl.

From the above, firefly larvae and the like are likely to inhabit, and the probability of going up to land and becoming adults is increased.

In addition, a large number of pores of the porous material serve as a home for microorganisms (such as beneficial bacteria that decompose organic substances and plankton) and proliferate, so that harmful substances in water are decomposed and water is purified. Therefore, abundant foods such as fish and other vertebrates will be provided. In addition, dissolved oxygen in water increases due to photosynthesis of algae attached to the porous material.

Therefore, an environment suitable for inhabiting aquatic insects such as fireflies, microorganisms, algae, fish, and other vertebrates can be formed.

It is a seawall lining block provided with a filling means for transferring moisture between the porous ceramic plates.

In this invention, by connecting a plurality of porous ceramic plates via the filling means, a porous material having a large surface area capable of absorbing water up to the upper end and retaining the water therein can be easily formed. Therefore, the same operation and effect as the case of the invention described in claim 4 can be obtained, and even if the main body is tall, a porous material having a height higher than that of the main body can be more easily formed.

According to a sixth aspect of the present invention, there is provided a water supply means which is buried in the soil around the main body and the other part is brought into contact with the porous material so as to supply moisture in the soil to the porous material. This is a revetment lining block.

According to this invention, even if the water is dried, the porous material is replenished with the moisture in the soil. Therefore, it is possible to increase the probability that microorganisms, algae, snails, and the like survive until the water dehydration is eliminated. it can. Therefore, an environment more suitable for inhabiting aquatic insects such as fireflies, microorganisms, fish, and other vertebrates can be formed.

Embodiments of the present invention will be described below with reference to the drawings.

The gutter block 10 according to the present invention is shown in FIG.
And a main body 1 for forming a water channel as shown in FIG.
1 and a porous material (21) attached to the inner side walls (12L, 12R) of the main body 11, wherein the porous material (21) contains water up to the upper end and can retain the water. Have been.

More specifically, the main body 11 is made of reinforced concrete in which a horizontal reinforcing bar and a vertical reinforcing bar are arranged, and has a U-shaped cross section. The inner walls (12L, 12R) of the main body 11 are smooth surfaces.

Next, the porous material (21) has water absorption and water retention, and has a height equal to or higher than the main body 11. Here, “the height is equal to or greater than the main body 11” means that the porous material (2
When 1) is attached to the inner side walls (12L, 12R) of the main body 11, it means that the upper end protrudes at the same level as or higher than the upper end of the main body 11. In this embodiment, the porous material is formed of a porous ceramic plate 21 attached to a part of the inner side wall (12L, 12R) of the main body 11 using an adhesive or the like.

The porous ceramic plate 21 is formed mainly of blast furnace slag from which stone powder and sulfur generated in the production of Oya stone have been removed, slag of waste, and the like. The ceramic plate 21 has a large number of fine holes of about 10 μm, and the holes hold water. The water content is 30 to 40%, and water can be sucked up by capillary action.

On both sides of the ceramic plate 21, andesite (such as Asama rock) suitable for the inhabitation of microorganisms and the propagation of algae
And a plate 31 on which a large number of chart rocks are attached.

The inner side wall (12L, 12L) of the main body 11
R) The ceramic plate 21 may be attached to the whole. Further, a ceramic plate 21 may be attached to the bottom surface 13 of the main body 11.

Microorganisms and algae serving as baits adhere to the surface of the plate 21 and easily grow and propagate. For example, if the amount of water flowing in the gutter increases and the flow velocity increases, the snails can evacuate to the portion of the ceramic plate 21 protruding from the water surface (Q), so that the snails are washed away with the water. Is less.

Therefore, since the snails serving as food are abundant, firefly larvae can easily inhabit.

Further, since the porous ceramic plate 21 absorbs water up to the upper end and holds the water inside, the portion that goes outside from the water surface (Q) is also humid and has a temperature lower than the water temperature. The difference is small. Moreover, since many fine holes are formed in the surface of the ceramic plate 21, firefly larvae and dragonfly larvae are easy to get on. For this reason, the firefly larvae are likely to crawl up even when it does not rain, as well as when it is raining when the firefly larva lands. Dragonfly larvae and frogs are also likely to crawl.

From the above, firefly larvae and the like easily inhabit and increase the probability of going up to land and becoming adults.

A large number of holes in the ceramic plate 21 contain microorganisms (bacteria that are useful for decomposing organic substances, plankton, etc.).
As it breeds as a habitat, harmful substances in the water are decomposed and the water is purified, and abundant food such as fish and other vertebrates is provided. Furthermore, the dissolved oxygen in the water increases due to the photosynthesis of the algae that propagate on the ceramic plate 21.

Accordingly, an environment suitable for inhabiting aquatic insects such as fireflies, microorganisms, algae, fish, and other vertebrates can be formed.

Further, since the ceramic plate 21 and the plate 31 do not elute alkaline components into water, unlike the concrete surface, from this point also, aquatic insects such as fireflies, microorganisms, algae, fish and other vertebrate animals are also considered. It is suitable for inhabitation such as.
