BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterway block in which a bypass for accumulating water can be provided in a part of a waterway and which is ecologically friendly.

[0002]

2. Description of the Related Art With recent advances in field maintenance, the number of living creatures such as frogs is decreasing. The environment for breeding frogs is being lost as the three-way construction of the waterway progresses. Conventionally, as for the rescue of living things that fall into the drainage channel, there is an example in which a slope-shaped escape channel is provided in the channel, as in Japanese Patent Application No. 3-32311. However, sufficient consideration has not been given to the reproduction of organisms in the canals constructed by the canal blocks, that is, spawning and hatching.

DISCLOSURE OF THE INVENTION According to the present invention, a waterway block can be handled in the same manner as before during construction, and after construction, a bypass waterway portion is provided in a part of the waterway to provide a breeding ground for frogs and the like. It is intended to provide a type of waterway block.

[0004]

According to the present invention, the above problems are solved.
The problem was solved by providing the bypass water channel portion 3 inside the skeleton body 1 of the water channel block composed of the left and right side walls and the bottom slab by the inclined partition 2 raised from the bottom slab substantially parallel to the side walls. The inclined partition 2 referred to here is provided in one or a plurality of in the flow direction in the frame 1 of the block for a water channel, and the skirt portion 2a which is a part of the inclined partition 2 is located in any part of the block body 1. It has a slope portion 2b near the bottom surface, which is inclined from this, and a top portion 2c. The skirt portion 2a, the slope portion 2b, and the top portion 2c do not necessarily have to have clear boundaries, and for example, the whole may be curved in an arc shape. The slope may be in a linearly inclined state, a staircase shape, an arc shape, or the like, and may be provided with unevenness for preventing slippage.

It is advisable to provide a weir 4 for storing water in the bypass water channel portion 3 or to lay stones 5 in the bypass water channel portion 3. The weir 4 is preferably provided in the bypass water channel portion 3 in the shape of a rib, but other means for making the bypass water channel portion 3 have a structure for storing water, for example, the weir also referred to here around the recessed portion recessed from other portions. is there. The weir 4 may be integrally formed using natural stone or pseudo stone so that water can be stored. It is more preferable for the body 1 to have through holes 6 and 7 in the side wall 1a or the inclined partition 2.

[0006]

With the structure in which the bypass channel part 3 is provided by the inclined partition 2 in the skeleton body 1 of the channel block, the inside of the skeleton 1 is the main channel part 8 of the channel and the bypass channel which provides a breeding ground for frogs and the like. It is divided into a part 3 and an inclined partition 2. In addition to the function of a partition, this sloping partition 2 also has frogs and the like that have grown from the hem 2a, which is a part of the sloping partition 2, climbing the slope 2b
You can reach 2c, jump out of the waterway from here, and leave the nature nearby. For organisms that are difficult to jump out of the top, a slope between the top 2c and the side wall of the block can similarly be used to make a nest using the slope.

When the weir 4 is provided in the bypass water channel portion 3, water is stored in the bypass water channel portion 3 regardless of the water level in the main flow channel portion 8 even if the water level is lowered, and spawning or hatching of organisms such as frogs. Will be useful to. In addition, by putting natural stones or artificial stones 5 in the bypass water channel portion 3, it becomes closer to nature such as giving a living place for living things.

When the through hole 6 is provided in the side wall 1a on the side of the bypass channel 3, grass rooted outside the channel extends from the through hole 6 into the channel to maintain a natural landscape in the channel, and frogs and the like. It enables the existence of insects, etc., which feed the living creatures.

When the through hole 7 is provided in the inclined partition 2, the main flow passage portion 8 of the water passage and the bypass water passage portion 3 are in the water communication state at the level of the through hole 7 or more, and living creatures can come and go. Become.

1 is a perspective view of a first embodiment of a water channel block according to the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a sectional view taken along the line AA in FIG. 2, and FIG. A sectional view and FIG. 5 are sectional views of the same CC section. As shown in these figures, this waterway block is provided with a sloping partition 2 in an upright state inside the skeleton body 1 of the waterway block which is formed in a U shape by the left and right side walls and the bottom plate. As a result, the main flow path section 8 and the bypass water channel section 3 exist. In this case, the inclined partition 2 has a mountain-like shape having a high central portion and has the lowest skirt portions 2a, 2a near both ends of the block. The skirt portions 2a, 2a are at substantially the same level as the weirs 4, 4 provided at both ends of the bypass water channel portion 3, that is, near both ends of the block. The central top 2c of the inclined partition 2 is located lower than the height of the side wall 1a of the block. Between the top portion 2c and the hem portions 2a on both sides, the slope portion 2b,
2b is formed in an inclined state.

Since the bypass channel 3 has weirs 4, 4 on both sides, water is always accumulated regardless of the water level in the main channel 8. A large number of stones 5 are provided in the bypass water channel portion 3. Stone 5 is a natural stone in this example. Frogs can lay eggs in the water between stones, and hatched tadpoles can hide themselves from foreign enemies. Further, since the through hole 6 is provided in the side wall 1a, grass can grow. The joint between the adjacent blocks will not be described in particular, but a conventionally known concave-convex joint or the like can be used in any of the following embodiments.

FIG. 6 (a) is a second block of the waterway block according to the present invention.
The top view of an Example, (b) is DD sectional drawing in (a) figure.
The water channel block is provided with the main flow channel portion 8 and the bypass water channel portion 3 by providing the saw-toothed inclined partition 2 in an upright state. Since the inclined partition 2 has a saw-tooth shape, it has a shape in which the skirt portion 2a, the slope portion 2b, and the top portion 2c are repeated twice. In this example, a weir 4 is provided at an intermediate portion of the bypass water channel portion 3, and water is stored between the blocks by connecting a plurality of blocks. No through hole is provided in the side wall 1a. However, since the inclined partition 2 is provided with the through hole 7, the main flow passage portion 8 and the bypass water passage portion 3 are in the water communication state at a level equal to or higher than the through hole 7. In addition, creatures can also come and go through the through holes 7.
