Description

[Detailed description of the invention] (Industrial application field) This invention is used for permanent concrete side wall revetment of rivers or large waterways, and is used for construction of deep seas where large fish and underwater animals can live. Related to concrete foundation blocks.

(Prior art) A conventional concrete fish floor block or fish nest block is used alone or in combination to settle down on an underwater riverbed,
There were products that can be stacked and used for riverside seawalls and inhabit freshwater small fish and shellfish, but they are necessary for the inhabitation of large fish such as carp and catfish that live in rivers or large waterways with a length of more than 60 cm to 90 cm. configure Seto and edge and Fukajo and mud reservoir, yet with more revetment construction wall height 3m, load mounting on the top end 2.0 t / m ^2,
There were no products with side wall revetments that also served as earth retaining with a large integrated unit having a product resistance moment of 250,000 kg-cm or more.

(Issues to be solved by the invention) Therefore, the applicant of the present invention has designed these revetment works,
While engaged in the enforcement, the following issues were resolved and the product was devised.

One block and one block are easy to manufacture, and the product construction and handling are easy.

To make a beautiful appearance as a side wall construction seawall.

In addition to being structurally strong,
The product must be stable in sliding.

It must be a product with passive embedding as a side wall construction seawall.

Maintenance and inspection of the fish bed can sometimes be performed without obstructing the purpose, function, and effect of the side wall revetment.

After construction, it must be a product that composes the currents, pools, deep fields and mud pools necessary for the inhabitation of large freshwater fish.

(Structure and Example of the Invention) In consideration of the above-mentioned problems, the solved product of the invention will be sequentially described with reference to the drawings of the embodiment. The front wall 2, the top floor slab 3, the side walls 4, 4 and the virtual back heel slab 5, which constitute the makeup, are integrally formed, and a U-shaped full-surface cavity 6 is formed between the side walls.

The front wall 2 is provided with one or more through holes 7 for the height of the product.
1/5 or more (30cm or more) vertically long, at least 30cm
A hole with a size of 50 cm (size that can be inserted by humans) is provided, and in front of the hole other than the hole, in consideration of the beauty of the river bank side wall seawall, unevenness in block stacking (cloth, valley, random stack), natural stone, artificial wood, Patterns of animals, plants, etc. are provided with uneven grooves.

On both side walls 4, 4, a vertical side wall through hole 8 is provided near the center so that fish can pass through the adjacent product after the product is vertically installed, and an adjacent block is integrated on the upper part. The side walls 4, 4 protrude into the concave portions, and the bag Ω portion reinforcing bar 10 is embedded in the concave portions.

The lower part of the back wall 1 that forms the earth retaining part is configured as an L-shaped virtual back heel plate 5, and the lower floor slab width W depends on the soil pressure. The main reinforcing bar A, the distribution reinforcing bar B, the reinforcing reinforcing bar C, and the auxiliary reinforcing bar D are incorporated so as to be H × 0.6 or more, and the opposite side of the lower BOX-shaped contour wall terminal portion 11 and the virtual back heel plate 5. 12. Cast concrete more and manufacture the whole as an integrated product.

The construction method is that the bottom of the through hole 7 on the front wall of the product is a riverbed
20. Strike the foundation concrete 19 so that the U-shaped cavity 6 is slightly lowered so that water can enter even during the drought season (standard is about 18 to 22 cm depending on the vertical gradient of the river). Then, the reinforcing steel bar 10 of the bag Ω of the product walls 4 and 4 is lifted and laid sequentially in the river extension direction.

The bag Ω of the top joint recess 9, which is formed between the products
The horizontal reinforcing bar 10 is made horizontal and stepped, and the overlapping Ω portion is provided with a length that can be connected to the vertical joint connecting reinforcing bar 13 at least D13 mm or more, the upper building block or the building wall 16, and joint concrete 14. Fill and complete.

(Function and effect of the invention) By constructing and constructing the product of the invention in this way, the product is in the form of a BOX and has a heel plate, which makes it easy to manufacture and eliminates defective products such as product scumming and chipping. There is no worries, there is a sense of stability of the whole product in the construction handling, and once the basic concrete is made, even if there is some underground seepage water, the construction can be done quickly and it is economical.

Since the front wall 2 forms a well-balanced decorative surface with the play hole 7, the front wall 2 has an aesthetic appearance as an earth retaining bank.

-Integrated with the back wall, front wall, both side walls, it is a BOX-shaped reinforced concrete product, it is not only structurally tough, but also at the site where the stress due to the load on the back is different, it is not shown, but the virtual back heel This can be easily accommodated by using a mold that can adjust the length of the plate 5 and manufacturing a product having this length changed according to the site. In addition to the product buried in the riverbed as shown in the construction section schematic diagram, this product is connected with the Ω rebar 10 in the top end joint recess 9 adjacent to the product and casts concrete to ensure stability. More secure.

Since the front wall 2 is close to a straight line parallel to the longitudinal direction of the river at the time of construction, it does not significantly impede the flow velocity of the river, and fulfills the purpose, action, and effect as the foundation of the side wall revetment. It is large enough to accommodate both through holes and humans, and sometimes allows maintenance and inspection inside the BOX.

There is a height difference between the riverbed and the U-shaped hollow part of the block body, which is not present in conventional products, and since it is BOX-shaped, sediment accumulates on the inner surface near the fish play hole 7, and both sides on the back A deeper field is created than a wall, and a turbulent flow velocity is formed in the play hole. In this part, small rivers and deep waters are formed across the river, and it becomes a playground for fish and a feeding ground. Foundation concrete 19 that constitutes a deep field, and BOX-shaped contour wall end 1 of the product lower part
By making some cutouts in 1, the cold spring water gushes out, and an optimal living place for underwater animals can be obtained.

The product of the present invention having the above-described configuration and construction method can be said to be a nice product in an era considering not only the role of river wall revetment work but also nature protection and river environment.
