Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete block used for consolidation of river revetments in consideration of the natural ecosystem and environment, or for use in coastal wave-dissipating parts.

[0002]

[Prior art]

 Conventionally, there were concrete products used for the consolidation of river revetments and the wave-dissipating parts of coastal areas.

However, in all cases, the entire surface excluding the concrete pouring surface is used as the finished surface of the formwork, so there has been no product that pursues more natural ecological and environmental aspects. Therefore, the inventor of the present invention has solved the problems of the product of the present invention as follows while engaging in the design, manufacturing, and construction of these products.

[0004]

[Problems to be solved by the invention] To reduce the mold weight with respect to the cost of the product and to easily manufacture the product according to the contour shape and the mass change.

It provides a hiding place and habitat for underwater fish and shellfish.

[0006] A natural environment product that does not feel uncomfortable for humans.

[0007] At the same time as considering a product in which algae and aquatic plants can easily inhabit, it is also considered to cultivate a river or seabed. The above is the solution problem of the present invention, and the solution means is as follows.

[0008]

[Means to be solved by the device]

 A pseudo stone block with a large variety of natural stones and a large through-hole for fish and shellfish, a hiding place, and a cavity for habitation is separately manufactured and stocked, and the main floor slab concrete is cast. At this time, this is set up in the required places, natural stones are embedded in the exposed surface of the surface, and natural cut gravel of the river is embedded in the void surface, which is the product of the present invention. It will be connected to the and will be moved irregularly by the flow velocity and the wave, and the means to cultivate the riverbed and the seabed will be taken.

This will be described with reference to the drawings of the embodiments.

[0010]

[Example of device]

 1. A plurality of through-holes of fish and shellfish that have the contour shape of natural stone and are greatly varied. And a hollow part to be used as a hiding place or a habitat 3. Large pseudo-stone concrete block with A. 2-1. As shown in the perspective view of one product, concrete is manufactured individually in advance with the lower part as the top (concrete placement surface) (at this time, the habitat environment of fish and shellfish (spawning of fish and shellfish and adhesion of algae) is better. Idea As shown in Figure 2-2, a mat or net may be attached to the inner surface), and this is cured and stocked.

Next, although not shown in the drawings, the slab concrete 1. (Reinforcing bar 5. if necessary) through hole 2. And cavity 3. Pseudo stone concrete block A. Embedded height H-1. After reaching the height of, the pseudo stone block A -1. And set the floor slab concrete 1. Is H-2. When it reaches the height of the stone block A-2. ... A-N. And Figure 3. Set like.

Once this is done, concrete 1. To a predetermined height EH. Placed slightly lower (considering the volume of buried natural stone B. and gravel C. for cutting), then natural stone B. When burying the concrete in a key place by burying about 1/2, if the concrete is hard at this time (slump 5 cm or less) and it is difficult to bury it, cover it with a cushioning material such as a wooden board or thick cloth so that it has concave and convex changes It is driven into a specified height and buried.

[0013] Furthermore, on the surface of these voids, a gravel of about 10 to 60 mm or a cut gravel C. After curing, the product is taken out by removing the outer formwork with built-in contours.

Next, the product of the present invention is claimed in claim 2. As shown in Fig. 5, in order to improve the ecosystem and environment of underwater small animals. Natural tree D. Or bury it in a required place on the concrete surface (more than 1/2 of the cross section), or 7. Plant roots with submerged soil like nets or vinyl pots. It is tied up and buried.

Furthermore, in the field where the vertical gradient of the river is relatively large or high waves are rushing due to the shallow depth of the rocky coast, the results shown in FIG. Figure 8. Through hole as shown in 2. And cavity 3. Pseudolith Block A. Considering the local water speed, the large and small products can be slightly stretched and bent to prevent corrosion. 6. (Zile rope or galvanized chain) is used to connect a plurality of pieces linked to a simulated stone block stone F. As a construction.

The product of the present invention configured as described above has the following actions and effects.

[0017]

[Advantage and effect of the invention] Shape and size, and especially large stones that cannot be freely obtained at low cost. By constructing the parts, sometimes coloring and pre-manufacturing and placing them in stock, when manufacturing the main body of the product of the present invention, only the contour formwork at the floor slab height is required. Even with the above products, the cost of formwork is low, and it is easy and quick to manufacture.

[0018] A large number of large pseudo-stone blocks that form the projections have through-holes for fish and shellfish at key points and are linked to the cavity that can be used as a house, so the river is flooded or the sea is rough. At times, it serves as a shelter or hiding place for small fish, and sometimes as a feeding ground.

Through the floor slab, a relatively large size pseudo stone block that is rich in color and variation, and a relatively large pseudolite block and natural stone of cobblestone (sometimes mixed stone), and surface construction with cut gravel Therefore, the exposed surface is close to the natural riverbed grain size arrangement and does not cause discomfort even when viewed from land.

Also, by embedding natural trees and plant roots on the surface of this product, algae and aquatic plants can easily settle, and it is not only effective as a feeding ground for small fish and shellfish, but it also has a longitudinal profile. In the case of large rocks and shallow bedrock, Fig. 7. ~ FIG. By using a free rock block that can be freely expanded and contracted and bent, it is possible to cultivate the riverbed and seabed with water currents and sea waves.
