Abstract

PURPOSE:To utilize revetment blocks as a fish-nest block, in which aquatic living things can live and increase, or as the material, with which firm revetment can be constructed, by placing simple-formed revetment blocks in layers. CONSTITUTION:A firm revetment is constructed by accumulating zigzag many blocks, in which front and rear wall plates are erected in the form of a letter U on a trapezoidal base plate 1, in which partition plates running fore and aft are integrated together with the wall plates at the upper (vertically) and middle (widthwise) part of the wall plates, and in which recessed parts 6 are formed in the base plate 1, a middle partition plate 5, and in the side part of the front and rear wall plates. An entrance for fish is formed in the front wall plate 2 in order to produce a cavity part 14 having a communicating hole, which is connected to the entrance and everywhere, and allowing fish to live therein. With this contrivance, fish, large and small, are encouraged to live, lay eggs, and to hatch eggs therein. At the same time, firm revetment and nature can be revived and protected, and moreover fine views can be presented.

Description

Detailed Description of the Invention

[0001]

[Industrial application] The block of the present invention is used for construction or settlement of revetments such as rivers, lakes and seas. It is also used as a fish nest together with revetments and also for river beds.

[0002]

2. Description of the Related Art Conventional revetment blocks are mainly used for retaining walls, and there were blocks that also served as fish nests under the surface of the water. However, for the breeding of algae, aquatic plants, etc. Could be difficult. In addition, it could not be used for riverbeds.

[0003]

[PROBLEMS TO BE SOLVED] The revetment block of the present invention is for the purpose of preserving the natural environment and revetment. At the same time, it creates and secures an environment in which large and small fishes can reproduce, spawn, and hatch, and also serves as a fish nest. It provides a revetment block that is not a structure but has a simple shape, is easy to produce, and maintains the natural environment by revetments even in riverbeds where the flow rate is usually small, and also uses newly improved and improved fish nests. .

[0004]

In order to solve the problem that the conventional block could not be solved, the present invention is mainly made up of a revetment wall as a retaining wall, which simplifies production as a block having a simple shape and simplifies construction and lamination work. The stacked blocks that can be used as fish nests each form a communication hole 6 and the cavities that are brewed are connected to each block, so algae, aquatic plants, large and small fish can freely enter and exit. When the water level rises, a retention point is secured in the laminated block, and when the water level becomes low, fish etc. can freely move to the bottom along with the water level through each communication hole 6, so the ecological form can be secured. Yes Use it for the same purpose on riverbeds, etc., and if the water level is lowered and the riverbed is exposed, drainage on the surface is improved to eliminate water pools due to recesses and damage the aesthetics due to water decay etc. It is necessary to always maintain the beautiful environment eliminated.

[0005]

The revetment block of the present invention is used as a fish nest block that also serves as a revetment. Therefore, in order to maintain the strength of the revetment, the front and rear upright wall surfaces are connected by the bottom plate to form a U shape. The bottom plate 1 is a block that is connected to the center of an upright wall and reinforced in an H-shape, and if the front and back are long, it is a block that secures strength by projecting and reinforcing the convex wall part 4 in the center. Since it is conducted to the ground through the wall, it has a structure that can handle a large load.

In order to maintain the natural ecology of the fish nest, the bottom plate 1 of each block and the wall surface are always provided with a concave portion 6 at the side end thereof, and the blocks are laminated through the notched portions to form communication holes. Since various fishes can freely flow in and out, including the inflow and outflow of water, when the water level increases, the hollow portion 14 brewed by stacking is used as a retention point and when the water level drops, Since it can move downward with the water level through the communication hole 6, it is possible to always inhabit with the water level and maintain the ecological form. Further, the bottom plate flat surface portion 1 forming the hollow portion 14 of the block is inclined in the direction of the recess 6 of the communication hole so as to facilitate draining so that mud and the like will not stagnate. This inclination is effectively used as a die during block production.

Further, in the hollow portion 14, a fish nest chestnut stone 15 or the like is placed so that fish can enter and exit without blocking the communication hole 6 so that fish can be laid, hatched, etc. For the purpose of securing the place, maintain and build the natural environment as much as possible so that large fish cannot eat it.
The block of the present invention can be used as a riverbed and can be effectively used as a fish nest together with a revetment.

That is,

2. When the block with the upper lid is laminated and constructed as described above, the riverbed is exposed when the water flow is small, but there is water in the narrowed riverbank, so the revetment is a fish nest, so as described above, It can live and maintain its ecological form. At this time, it is necessary to form a heavenly shape with good drainage so that no water can be collected on the upper surface or exposed surface of the riverbed, and be sure to incline it toward the river. By constructing as described above, it is possible to protect and maintain the aesthetic appearance due to the generation of mosquitoes due to water pools and the decay of filth.

Example 1 The present invention

FIG. 1 is a perspective view of basic blocks A, B, and C. This block is a block in which a reinforcing convex portion 4 is projected in the middle and is short when the front and rear wall plates are long. In the block, only the front and rear wall plates do not require the intermediate reinforcement 4.

[FIG. 2] is a front view of the block, in which the width of 1/2 is shifted to form a three-tiered stack, which is a mistake as a retaining wall block and can secure the most strength. In addition, a communication hole 6 is formed in the front by adjacent blocks in parallel with each block, but this through hole is an entrance through which water, fish, etc. can advance, and this entrance hole has the same shape in the rear wall plate 3 middle 4 as well.

2 is in complete communication as indicated by the broken line arrow.

[0010]

[Fig. 2] is a plan view of one parallel stage, but the widths of the front wall surface 2 and the rear wall surface 3 are narrower.

[FIG. 3] At the same time, the bottom plate 1 also has a ladder shape.

[Fig. 5] When used in a curved part of a river When the front wall plate 2 is installed at a fixed position and can be expanded and contracted by inward bending and outward bending to change the shape of the fan, and there is a gap in the rear wall part 3

[Fig. 6] As shown in Fig. 6, it can be fixed and stabilized by the stone 17 or the like. In addition, since the locking bolts 12 embedded in the upper part 9 of the central partition plate 5 including the vertical connection are projected, the mortar 10
By doing so, it can be fixed easily in all directions and highly stable construction can be performed.

This

Referring to FIGS. 4 to 5, since the bottom plate 1 is formed with concave portions, respectively, the upper and lower communication holes 6 are secured, and the hollow portion 14 can be formed around the communication holes. Available. Since this space is large, it can be understood that large fish come in and out, but small fish are unstable and difficult to live in.

[Fig. 10] As shown in Fig. 10, natural stones such as fish nest chess stones 15 should not block the communication holes 6 in the bottom plate.

As shown by the solid line arrow in FIG. 10, it is necessary to be careful not to block the entry and exit of large fish, and it is necessary to be close to the natural environment so that both large and small fish can provide a place for spawning and hatching. The communication hole 6 to the front and back and up and down

[Fig. 2]

As shown in FIG. 3, the left and right communication holes can be secured by forming the recesses 6 in the central wall portion 5, respectively, and the vertical contact portions for supporting the load can be secured.

[0012]

4-5, the bolt 12 for locking, the locking cutout portion 1
It can be understood that it is fixed by 3, and the upper block is locked to the lower block by utilizing the notches 7 and 8 of the L-shaped portions on the upper and lower sides of the front wall plate 2 to support the earth pressure. . In addition, as shown in each figure, all the wall surfaces are inclined toward the side edges to improve the drainage without accumulating mud and the like, and also to be a die in block production, which is also good in productivity.

In the block of the present invention

[Fig. 8] As shown in Fig. 8, when the purpose of the lower fish nest is to finish the stacking and stack the upper part with another retaining wall block, the block is sealed with the lid plate 11 on the uppermost part of the present invention to secure the strength. Things are possible.

[0014]

Example 2

The effect and usage of the block of the present invention can be understood in the first embodiment, but this embodiment is applied to a riverbed.

FIG. 9 will be described. Large, medium, and small rivers are not always full and the amount of water is small in the dry season, so it may not be possible for fish to live and escape from the fish nest block. Since it is connected to the hollow part that is a fish nest by the communication hole of, the habitation of fish can be maintained and secured.

In this case, the uppermost cover plate should be inclined from the level GL in the direction of the river, and the top face of the cover plate should be a convex shape instead of a concave shape, so that a well-drained cover plate should be used.

It is also possible to use another slope block 16 as shown in FIGS. When the riverbed is exposed during the drought season and water is accumulated in the recesses, mosquitoes breed and filth accumulates and rots or miscellaneous things constantly accumulate, which damages the beauty of the river and contributes to natural destruction. Will also be. As a result, a natural environment can be maintained by using the block of the present invention.

[0016]

INDUSTRIAL APPLICABILITY As described above, the present invention is a revetment block, but it can also be used as a block for fish nests such as rivers, lakes and coasts. In the basic land industry, the stone is hardened with stones and leveled with underfilled concrete, and in the case of a riverbed, the front plate is used as a reference, and the slope is set to be slightly inclined from the level GL in the direction of the river so that it is well drained. Since the width of the back plate 3 is narrower than that of the front plate 2 in the curved portion, both inner and outer bending can be freely installed in a fan shape, so that the front plate portion can be installed as it is regardless of the aesthetic appearance of the width.

The layers are stacked one by one, but the strength of the retaining wall against a load is strong because all the loads are transmitted in the vertical direction, and a strong supporting force can be obtained. In addition, the stack of blocks is laterally moved by 1/2 to form a third stack, which is excellent in stability.

When laminated next, there is an entrance where fish can go in and out over the entire surface, and this hole communicates with the entire block in the vertical and horizontal directions to form cavities in each, so that it becomes a retention point when running water is severe. In addition, by placing the chess stones 15 for fish nests in this cavity, a variety of fish of various sizes will inhabit and become a natural ecology site for spawning, hatching, etc. If the water level drops, it is possible to freely escape downward. It will be a fish nest that can be made.

It is also used for riverbeds, but in this case as well, it should be inclined toward the river so that water is drained well, and care should be taken not to make a recess on the surface of the lid plate so that water will not collect and to prevent dirt from remaining. At the same time, mosquitoes should not occur. In the case of a riverbed, it is possible to connect two or three depths in the depth, that is, if you want to widen the width, you can stack deep fish nests. Since the concave portion 6 matches with the concave portion 6, the fish nest function is possible and can be secured. In this way, the natural environment is regenerated, the breeding of aquatic organisms is promoted, and the beauty of nature is pursued.
