Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete canal with improved landscape and biological environment, and more particularly to a canal capable of growing waterside plants along the canal.

[0002]

2. Description of the Related Art Currently used irrigation channels are industrial,
Regardless of whether it is for agriculture, it is a U-shaped groove made of concrete. Therefore, the appearance looks like the texture of concrete,
It does not match the surrounding landscape.

[0003]

In addition to the above-mentioned landscape destruction, concrete canals do not grow bacteria in soil-less canals, and even if there is soil, alkali peculiar to concrete affects the water supply and Small animals don't grow. Therefore, it cannot serve as a growth environment for aquatic animals such as crayfish, sour crabs, and gengorou and fishes such as crucian carp, carp, and haya, which lead to environmental destruction. An object of the present invention is to solve the problems of the concrete canal as described above and to prevent a water death accident that is likely to occur in a slightly large canal.

[0004]

Means for Solving the Problems A concrete canal according to the present invention, which has an improved living environment, has a water-permeable wall that maintains a gap along a concrete inner wall of the canal and a soil for growing waterside plants that fills the gap. And is provided. In addition, it is recommended that the water permeable wall be made of a net, a sheet or the like as a core material, and a wall body formed by water-permeablely joining small natural stones. In addition, it is recommended that the soil has a composition that can mix the porous material and the plant fiber into the general soil and prevent the soil from flowing out by adding the roots of the waterside plants grown to this. Further, it is recommended that both the water channel and the water permeable wall have a U-shaped groove shape, the water permeable wall resting on the bottom of the water channel, and the above-mentioned soil gap is formed on both sides or one side thereof. It is recommended that the water-permeable wall has a locking piece protruding from the outer wall surface so as to be engaged with the locking member protruding from the inner wall surface of the water channel. It is recommended to set the upper edge of the permeable wall at a height midway between the water surface when the waterway is full and the water surface when the water is dry. In addition, it is recommended that recesses for growing underwater small animals be provided at random on one or both of the inner wall and bottom surface of the water permeable wall.

[0005]

In the concrete water channel of the present invention, the soil for growing waterside plants is provided along the inner wall of the waterway, and the permeable wall is provided outside the waterway. Therefore, the soil can be prevented from being washed away and the water necessary for growing waterside plants can be sufficiently supplied. . Waterside plants are suitable for the waterside and are easy to grow. The permeable wall is a net or sheet beforehand,
That is, if a braided reinforcing bar, a wire net, a lath net, a perforated plate, various fiber sheets, etc. are used as a core material and a small natural stone is bonded and molded into a wall body, it is easy to handle and installation work is easy, and the water permeability is sure.

In the above soil, if porous material and general soil are put together with plant fibers and roots of riparian plants, the porous material becomes a habitat for many bacteria, feeds small animals, and the small animals fish. Etc. The concrete canal of the present invention is mainly applied to irrigation canals and road gutters, but both are mainly U-shaped, and if the inner permeable wall is also a small U-shaped, it is easy to install. It is stable just by placing the lower surface of the U-shaped permeable wall on the bottom of the water channel, and it is easy to make soil for growth on one side or both sides.

When installing a permeable wall of almost the same shape in a U-shaped channel, if the locking member is taken out from the inner wall surface of the former and the locking piece is taken out from the outer wall surface of the latter, both can be fixed during installation. It's easy. If the upper edge of the permeable wall is set at an intermediate height between the water surface when the canal is full and the water surface when the water is drought, even if the waterway is deep enough to kill people, a step will be formed in the middle of both inner walls. Be dead. You can also grab waterside plants and climb up.
By providing recesses for growing underwater small animals on one or both of the inner wall and bottom surface of the permeable wall, small animals can be saved even if the flow velocity is high when the water is full, and water can be pooled at the bottom even when the water is drought and drowning. It can also be used as a clue for the victim.

FIG. 1 shows an irrigation canal of one embodiment of the present invention. Part 1 is a U-shaped grooved concrete water channel, 2 is a U-shaped grooved permeable wall in the inner wall, and the gap between the channel 1 and the permeable wall 2 is mixed with porous material and plant fiber in general soil The special soil 3 is filled. Water 4 is flowing through the permeable wall 2. Waterside plants 5 extend from the soil 3. The cross section of FIG. 1 is as shown in FIG. The permeable wall 2 is placed at the center of the bottom of the water channel 1 and has soil 3 on both left and right sides. The upper edge of the permeable wall 2 and the upper edge of the soil 3 are lined up and extend downward from the upper edge of the water channel 1.

The water surface when the water 4 is full and when it is drought is shown by dotted lines and solid lines. The upper edge of the permeable wall 2 and the soil 3 is at an intermediate height between both water surfaces, and a step is formed on the inner wall of the waterway. ing. This step is the decisive factor in preventing water death accidents in the canal. When full,
The soil 3 sinks below the surface of the water, but the waterside plants 5 are not damaged and the soil is not washed away. When the water is drought, there is no problem in rehydrating the plant 5 since it rises from the lower part of the soil 3 through the permeable wall 2 as shown by a thick arrow in the figure.

As shown in FIG. 2 and taken out in FIG. 3, the locking piece 6 projects from the outer wall surface 2a of the water permeable wall 2. When the locking member 7 protruding from the inner wall surface of the water channel 1 and the locking piece 6 are joined by bolts and nuts omitted in this example, the water permeable wall 2 is fixed. The locking member 7 on the side of the water channel 1 is built in when the water channel is manufactured. As shown in FIG. 3, the locking piece 6 on the side of the water permeable wall 2 has its base portion bent to the core material (lath net) 8 fixed by adhesion, welding or other means so that only the protruding portion is exposed. The core material 8 was water-permeablely solidified with the natural stone 9 and cement or an adhesive. The permeable wall 2 in FIG.
Is a U-shaped groove, but FIG. 3 shows an embodiment in the form of a single flat plate. When fixing the water permeable wall 2 of the present invention to an existing water channel, wedges, bracing materials or the like may be applied.

In FIGS. 4 and 5, raised portions 11 are provided on the bottom surface of the U-shaped water permeable wall 2, and a recessed portion 10 for growing small animals is provided between them. FIG. 6 shows an example in which recesses 10 'for growing small animals are provided on both inner walls of the permeable wall 2. In this case, the gap where the soil 3 enters is the recessed portion 1
Only the position without 0'is scattered.

Although a few examples have been described above,
It goes without saying that the embodiments of the present invention can be variously changed and applied according to the implementation conditions without changing the gist thereof. For example, the water permeable wall 2 is made into a single flat plate shape as shown in FIG. 3, and a gap for soil 3 is opened along one inner wall of the water channel 1 to stand on the bottom of the channel, and as shown in FIG. It may be fixed to. The material may be water-permeable and durable ready-made plate material that does not use natural stone. The soil 3 contacting the inner wall of the waterway 1 is not always provided over the entire length of the waterway. It is left up to the designer to skip the area as shown in FIG. 6 or to make only the required section on one side.
