Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is mainly used for riverbeds of rivers and the like, and relates to a floor protection block for protecting riverbeds by preventing scouring of riverbeds and seawalls by running water.
[0002]
[Prior art]
Conventionally, a concrete block for protecting a river bed has been proposed as a protective floor block. For example, in Japanese Patent Laid-Open No. 7-268837, an embedded natural stone or pseudo-stone or pseudo-rock pattern is formed on the surface of a plate-like member formed with a concave groove intersecting the bottom surface, and an opening is linked to the opposite side surface of the plate-like member. River consolidation blocks with fixed members have been proposed. Japanese Utility Model Laid-Open No. 7-31926 discloses a foundation concrete block, pillars standing at its four corners, and a frame having holes at both ends, and the columns are passed through the holes so that the columns are placed between the upper and lower frames. There has been proposed a sinker composed of a frame formed by assembling a number of steps in a grid pattern at intervals, and a stone block packed in the frame.
[0003]
[Problems to be solved by the invention]
However, in the river consolidation block proposed in Japanese Patent Application Laid-Open No. 7-268837 as described above, it is disposed on the bottom of the river in a plane and is suitable for protecting the river bed, but is disposed on the riverbank. It is difficult to use to protect and protect the shore of Shishigishi. In addition, the sinking work proposed in Japanese Utility Model Laid-Open No. 7-31926 is suitable for laying on the riverbank and solidifying and protecting the bottom of the river bank. It is difficult to use to protect the riverbed. In other words, it was necessary to prepare many types of blocks for river floor protection and root consolidation.
[0004]
Therefore, the present inventor has conducted intensive research in view of the conventional drawbacks. As a result, it is possible to cope with floor protection and root consolidation with a small number of blocks, which is suitable for breeding aquatic organisms such as fish and plant growth. It proposes a firm block.
[0005]
[Means for Solving the Problems]
In the floor protection block according to claim 1 of the present invention, a thick plate-like base portion is provided with a communication hole and an upper and lower connection portion, a plurality of convex portions are provided on the surface of the base portion, and the back surface is a flat surface. A horizontal connecting portion is provided, and the base portion has an octagonal shape in plan view. The central portion of the four side surfaces thereof is recessed to form a recessed portion, and an annular reinforcing bar is provided at the center of the recessed portion. In the center of the base, a through hole is provided to form a communication hole. Around the communication hole, there are four horizontal oval-shaped convex portions and each convex portion is not provided with a horizontal connecting portion. The four horizontal oval-shaped convex portions provided in parallel with the four side surfaces are the same shape and the same size, forming four sides of a regular square with the corners cut off and being cut off. Are placed on the surface of the base with the corners facing the horizontal connection Te in which one through hole each of which is made with upper and lower connecting portions provided between the side surfaces an outer horizontal connecting portion is not provided in these protrusions, the Mamoruyuka root compaction block By appropriately combining, it can be used as various floor protection blocks and root hardening blocks.
[0006]
Further, the floor protection block according to claim 2 of the present invention is formed by a set of the floor protection blocks, the flat surfaces of the back surfaces are brought into contact with each other and connected by the upper and lower connecting portions, and are arranged on the river bed. In this case, the convex portion formed on the bottom surface is unlikely to bite into the river bed, and the convex portion on the top surface resists water flow, weakens the flow velocity, and protects the river bed. In addition, aquatic organisms are easy to propagate in voids and communication holes formed between the base and the river bed, and the natural environment is not impaired.
[0007]
The root block according to claim 3 of the present invention is such that the upper block formed so as to form a gap when placed on the flat surface of the back surface of the floor protection block is a floor block. It is placed on the flat surface of the back side of the compaction block, and a log 8 assembled in a cross-beam shape is attached on this upper block. After this root consolidation block is arranged on the shore, If the horizontal connecting part is connected with a connecting bracket and the upper well is filled with natural stone, a space with various shapes will be formed, and a large depth gap formed between the guard bed consolidation block and the upper block It is suitable for various fishes and aquatic life.
[0008]
Further, according to the fourth aspect of the present invention, in the root consolidation block according to the present invention, a set of the floor protection blocks is a set, and a convex portion of one of the floor protection blocks and a flat surface on the back surface of the other floor protection block are in contact with each other. After the root block is placed on the shore, if the soil is filled in the communication hole of the block or other space, the vegetation function is excellent and the aquatic The plant can grow. It also becomes a habitat for insects, small animals, and birds, and a spawning place for fish.

The logs 8 are combined in a cross beam shape on the upper side and connected by bolts 11 inserted through the upper and lower connecting portions 6. The upper block 7 has protrusions 71 formed at the four corners of the lower surface, and a gap 13 is formed when placed on the floor protection block. This assembled block is placed on the shore of the revetment to form a solid block. After the root block is disposed on the shore, the horizontal connecting portions 3 of the adjacent blocks are connected by connecting metal fittings, and natural stone 9 is filled in the upper well beam. This firming block protects the shore of the revetment and has an excellent fish nest function. In addition, the natural girder 9 is filled with the natural stone 9 to form various sizes of large and small spaces. Suitable for fish and aquatic life.
[0012]
FIG. 4 is an assembly diagram showing a third example of the combination of the floor protection blocks according to the present invention. The combination of this example is mainly used for the revetment of the revetment and becomes a root-clamping type. The bolts 11 are stacked up and down in two steps with the convex part 5 of the revetment root-clamping block facing downward and inserted into the vertical connection part 6. It is connected by. This assembled block is arranged on the butt and becomes a root block. After this root block is disposed on the shore, the horizontal connecting portions 3 of adjacent blocks are connected by connecting fittings, and the communication holes 4 and other space portions of the blocks are filled with earth and sand 12, and the surface of the earth and sand 12 Is covered with a fiber mat 10. This firming block protects the shore of the revetment and has an excellent vegetation function. Moreover, since the surface of the earth and sand 12 is covered with the vegetation mat, the outflow of the earth and sand 12 is prevented, and the growth of aquatic plants can be achieved. It also becomes a habitat for insects, small animals, and birds, and a spawning place for fish.
[0013]
FIG. 6 is a cross-sectional view of a river showing an example of an embodiment of river construction according to the present invention. As shown in this example, a protective floor block is preferably used for the riverbed, and a root block is used for the heel. As shown in this example, there is only one type of floor protection block that is the basis for forming the three types of blocks. By combining the upper block 7, the log 8 or the fiber mat 10, the construction of any place in the river Can be easily done.
[0014]
The floor protection block and the upper block 7 in the present invention may be made from appropriate materials such as ordinary concrete and porous concrete. Further, natural stone 9 and earth and sand 12 filled in the block are preferably collected near the construction site because they are suitable for the climate of the site.
