[0005]

[Action]

 According to the present invention, the cutouts of the covering blocks and the cutouts of the adjacent covering blocks are abutted by the abutting of the covering blocks to form a lateral water channel. Moreover, a rectangular hole is formed in the cylinder where four covered blocks meet, and this hole forms a water channel extending in the vertical direction. Many water channels, including through holes in the coated block, form the upper surface of the foundation ground at the bottom of the water. Is produced in. Further, since the covering block is provided with legs, a water channel is also formed on the bottom surface of the covering block. The waterway formed by the cutouts of the covered block abutting each other is a light-shielded waterway, which is suitable for habitation of aquatic plants. Moreover, this waterway becomes a hiding place, and it is also suitable for inhabiting seafood that needs hiding places such as abalone and lobster that need hiding places. The waterway formed by the cutouts of the covered block is in communication with the rectangular hole formed by the four covered blocks facing each other, and many branched waterways necessary for habitation and waterways that are difficult to reach are formed. The water bottom structure is suitable for inhabiting aquatic flora and fauna such as seafood, seaweed and algae.

Further, since the upper surface of the covering block is uneven due to the depressions, seaweeds and water plants are likely to inhabit, and the depressions are the upper ends of the rectangular holes formed by the four covering blocks abutting against each other. The shape of the opening is widened, which facilitates the flow of water to the holes formed by the four covered blocks, and facilitates the aquatic fauna and flora to inhabit. Furthermore, since the upper surface of the coated block is uneven due to the depressions, stirring of the water flow is caused, and spores such as seaweed and aquatic plants can be easily introduced to promote the fixation. Since many water channels are formed in the laid covering block, the lifting pressure due to waves and water flow can be reduced, and the block is maintained in a stable state. When the covered block is used for the consolidation of rivers, stones or the like are buried in the rectangular holes or recesses formed by the four covered blocks butting together to form a cross shape of the covered block. Only the top surface is exposed, which does not impair the landscape of the river bottom when viewed from the ground. If natural stones are attached to the cross-shaped upper surface of this covered block, a more natural landscape will be created.

According to the second aspect of the present invention, the cutouts of the covering block are not abutted with each other, but the notch is located in a rectangular hole formed by abutting the four covering blocks. The uneven surface makes it suitable for places where light is hard to reach and hides, and promotes the inhabitation of aquatic plants.

According to the third aspect of the present invention, the fitting block is fitted into the rectangular hole formed by the four covering blocks abutting each other, and the protrusion of the head of the fitting block protrudes in a cross shape. Since the portion is placed on the upper surface of the covering block, a gap is created between the uneven portion on the upper surface of the covering block and the lower surface of the protruding portion of the fitting block, and a new water channel is formed. This waterway is a waterway that is suitable for a place where light is hard to reach and is hidden by the overhanging portion of the fitting block, and it is possible to further promote the habitation of aquatic plants and animals. Since a vertical through hole is provided on the upper surface of the fitting block, the water pressure of the through hole in the through hole can reduce the lifting pressure due to waves and water flow, and the fitting block can be maintained in a stable state. According to the fourth aspect of the present invention, by forming the lower surface of the overhanging portion of the fitting block as an inclined surface, it is possible to widen the gap between the upper surface of the covering block and the recessed portion and to prevent water from being exposed to light. Can be widened.

[0009]

[Embodiment of the invention]

 In the covering block according to the present invention, it is desirable that the open position of the cutout portion and the open position of the adjacent cutout portion are aligned at the same position. It is desirable that the notch has a triangular shape, but it may have another shape. The size of the covered block differs depending on the condition of the seabed, riverbed, or other waterbed to be laid, but as a general dimension, a covered block with a height of about 80 cm is used. The covering block is generally made of concrete. The size of the fitting block varies depending on the size of the covering block to be laid, but when the above-mentioned covering block having a height of about 80 cm is used, a height of about 130 cm is generally used. The fitting block is generally made of concrete.

A water channel 3a is formed by abutting the notch 3 of the covering block 1 and the notch 3 of the adjacent covering block 1. The water channel 3a is a square shape formed by abutting four covering blocks 1 together. Since it communicates with the holes 11, the water channels 3a are branched and extended in a grid pattern. In addition, since the water channel 3a formed by the cutout 3 of the covering block 1 is shielded from light, a bright and dark place necessary for inhabiting aquatic plants and animals such as seafood and seaweed is formed, and habitat promotion is sufficient. Can be achieved. Further, since the leg 2 is provided on the lower surface of the covering block 1, a water channel is also formed on the lower surface of the covering block 1, and this water channel also serves as a water channel for blocking light. Further, due to the unevenness of the upper surface of the covering block 1, it becomes easy to introduce a water flow into the holes formed by the abutting of the four covering blocks 1, and it is easy to introduce and fix spores such as seaweed. Since the covering block 1 is provided with the vertically long through holes 6 extending from the upper surface to the lower surface, the lifting pressure applied to the covering block 1 by the waves is reduced, and the covering block 1 can be maintained in a stable state.

Example 2 (see FIGS. 10 to 11) Example 2 shown in FIGS. 10 to 11 is a cross-shaped upper surface of the coating block 1 to which the cross-shaped upper surface 5 of the coating block 1 of Example 1 is adjacent. 5 is an example in which each covered block 1 is laid by rotating it by about 45 degrees so that it does not abut. Since the cruciform upper surface 5 of the covered block 1 is laid so as not to abut the upper surface 5 of the adjacent covered block 1, the cutouts 3 of the covered blocks 1 are not directly continuous with each other. Since the recesses 4 are in continuous communication with each other, the cutouts 3 of the coating block 1 are in communication with each other through the recesses 4, and the four coating blocks 1 are formed in a square shape formed by butting each other. The water channels that connect the holes 11 to each other are formed in a grid shape as in the first embodiment.
