DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is applied to, for example, seawalls such as rivers and coasts to serve as seawalls and to act as fish nests, and to have aquatic plants inside the front part. Fish nest blocks that are vegetated and their roots serve as food for fish, create a shaded and diverse space, and provide a place for spawning, habitat and evacuation of fish, and masonry using the blocks It was used as a seawall.

[0002]

2. Description of the Related Art Conventionally, this kind of block is effective as an evacuation place for fish during floods, but is not often used as a place for fish inhabitation, production, and fostering of fry under normal conditions. There was a face.

[0003]

Therefore, even in normal times, a more diverse space suitable for fish habitat is created, shading is created in the space, an environment suitable for fry life, and aquatic insects that feed on fish. The outbreaks must be able to gather and spawn fish, furthermore, fish can live in peace, and seawalls must create a natural environment landscape.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned inconvenience, and is constituted by a block having a cavity therein, and the upper portion is provided on the front surface of the main body. A block that is opened and provided with a planting portion with a water hole formed in the bottom and a ridge is provided on the upper surface of the rectangular plate-shaped main body, a concave groove is formed on the symmetrical lower surface, and a vertical groove is formed on the side surface. A groove is provided, and a box-shaped part narrower than the main body is formed on the front of the main body,
The inside is a hollow part, and a fish nest block consisting of a block used in combination with a side hole on the side is piled up along the slope of the revetment, the planting part is filled with earth and sand, and this willow, Plants such as reeds and cattails are planted, the roots are made to exist in the water, and the fish and shellfish are gathered to form a block revetment body that serves as an egg laying or habitat and evacuation site. With such a configuration, as the plants grow, they cover the block seawall and create a natural environment,
By breeding underwater in the water, the roots are a great evacuation place where fish hide from outside enemies, a place for fish to live and lay eggs. The effect of breeding is great.

Embodiment 1 will be described with reference to the drawings. FIGS. 1 to 4 show a block according to the present invention, wherein 1 is a rectangular plate-shaped main body, provided with a ridge 2 on its upper surface, a concave groove 3 formed on its symmetric lower surface, and a vertical groove on its side surface. A groove 4 is provided, a box-shaped portion 5 narrower than the plate 1 is formed in the front of the main body 1, a space 6 is formed inside the box-shaped portion 5, and a lateral hole 7 is formed in a side surface. 8 is
At the front of the box-shaped part 5, the front face is almost the same width, the top face is inclined,
The lower part is the planting part of the slender projection that is thinner when viewed from the side,
The inside is provided with a funnel-shaped water hole 9.

The block shown in FIGS. 5 to 8 is a block used together with the block according to the first aspect of the present invention. A ridge 11 is provided on the upper surface of a rectangular plate-shaped main body 10, and the symmetrical lower surface is provided on the symmetrical lower surface. A concave groove 12 is formed, and a vertical groove 13 is provided on a side surface.
A box-shaped portion 14 narrower than the main body 10 is formed at the front of the main body 0, a hollow portion 15 is formed inside the box-shaped portion 14, and a lateral hole 16 is formed on a side surface.

[0007] As shown in FIGS. 9 to 11, the block 17 used in combination with the block of the present invention according to claim 1 forms a base 17.
Piled up, filled the planting part 8 with earth and sand,
This is a block revetment in which plants 18 such as reeds and cattails are planted, the roots of which are made to exist in the water, and fish and shellfish are gathered to form spawning or habitat and evacuation sites.

[0008]

According to the present invention, the block main body 1 and the block main body 10 are alternately arranged, or two blocks are arranged so that the block main body 1 is interposed between several block main bodies 10, and the ridges 2, 11 are provided. On the lower surface of the symmetry,
Can be piled up very easily without any technique, so that the construction can be done easily and quickly, and the engagement of the ridges 2, 11 and the concave grooves 3, 12 disturbs the individual blocks. Can form a strong seawall without jumping out. Since the water hole of the planting portion of the block of the present invention always exists near the water surface, the planting portion 8 is provided.
The plant 18 planted inside the plant grows by absorbing water well and grows, covering the revetment surface and greening, thereby preserving the natural environment and creating a landscape, and shading the plant 18 and its roots. It forms a habitat and spawning place for fish, the soil inside the planting section 8 and the roots of aquatic plants also serve as a place for breeding aquatic insects, and aquatic insects also serve as bait for fish. Good breeding effect. In addition, the internal cavity 6 and the hollow 1
Numeral 5 is a fish nest, and lateral holes 7 and 16 on the side are a passage for fishes, and the movement of an adjacent block is also free.
