[Industrial applications]

 The present invention relates to a concrete revetment basic block constructed by planting aquatic plants in the toe part of the foundation part of a side wall revetment construction of a small river or an agricultural canal and constructing a BOX where fish and shellfish can live in the back soil retaining part. is there.

[0002]

[Prior art]

 For products that are used for the foundation of conventional concrete side wall revetment construction and that take into consideration the ecosystem of small animals that live in rivers and waterways, the utility model registration application proposed by the applicant of the present invention is There were No. 18500 (Actual Kaihei No. 2-109830) and its improved utility model registration application No. 5-65001.

However, these products are those in which the front river bed is constructed of natural river gravel or earth and sand, and it is necessary to insert a river bed or a water channel (depth to be buried in the ground, usually about 1000 mm in a river or water channel). It is not a product of a three-sided river revetment or a three-sided canal, which is a product that is used in the field, and whose front riverbed is also constructed of concrete.

Therefore, the applicant of the present invention has settled the following problems to be solved by the proposed product while engaging in the design, manufacturing, and construction of these products.

[0005]

[Problems to be solved by the invention] A product that is easy to manufacture, construct, transport, and handle. The low plate length can be constructed to be large with respect to the product height, and the product will be stable (against the soil pressure on the backside) even without rooting. Not only will be planted on the front of the underwater side wall to be used as a feeding ground, playground, and hiding place for underwater small animals, but also as a peaceful river revetment or waterway environment product that provides greenery to humans. It is assumed that a mud is built in the BOX where the small water animals live. It is a product that can be easily jointed with a canal floor slab and can build a three-sided canal.

In consideration of the above problem to be solved, the solution means of the present invention is as follows.

[0007]

[Means to be solved by the device]

 A structure that secures a low plate width of 60% or more of the product height in consideration of the construction, transportation and handling of the product and the earth pressure stress after the construction while at the same time making the concrete pouring surface at the time of product manufacturing a low plate back And

[0008] At the same time, a hollow BOX shape is formed with a double wall between the rear retaining wall and the front decorative wall, and this is used as a habitat for underwater fish and shellfish.

[0009] In addition, the front wall is used as a decorative wall surface, and a small wall is provided on the front wall and the front wall so that aquatic plants can be planted by putting soil and sand there. This will be sequentially described with reference to the drawings of the embodiments.

[0010]

[Example of device]

 In the embodiment, the lower floor slab 4-1. Or low version culvert 4-1. And sky deck 4-2. In addition, heaven end drain 4-2. Through the underwater toe soil retaining wall 1. And the front decorative wall above the normal water level 2. And the rear retaining wall 3. Build as one.

This rear earth retaining wall 3. The top is the slope protection construction material for river dikes or water revetments 13. Right angle abutment 7. If the slope is steep, the length of the slope is large, or the ground is soft, the lower floor slab 4-1. Virtual back heel plate 8. The length is adjusted to provide a stable product against earth pressure stress.

Next, the front decorative wall 2. Underwater toe Tsurudome small wall 1. 6. A seafood through hole with a hole slightly above the top of 2 or more are provided (when 3 or more are provided, they may be provided as steps considering the turbulent flow of water and aesthetics as shown in FIG. 1 of the embodiment).

Underwater toe soil retaining wall 1. Lower floor slab 4-1. The front floor plate B. Joint with rebar 9. To expose the waterway front slab B. If the is an assembly factory product, see Figure 2. As shown in joint concrete 15. And the front floor slab of the waterway B. In the case of the cast-in-place concrete, as shown in Fig. 5, this rebar 9. Using the front floor of the waterway B. To build.

Underwater toe earth retaining wall 1. And the front decorative wall 2. Planted in the concave part of and 12. Aquatic plants 10. At the same time as planting (perennial grass of the family Gramineae in the field where the flow velocity is high, and squid sprouts in the field where the flow velocity is low), the fish bed BOXA. In the cavities, there was construction diversion soil at the bottom of the local riverbed, although it depends on the local fish and shellfish. Or put small gravel.

The product of the present invention thus constructed has the following actions and effects.

[0016]

[Advantages and effects of the invention] Since the structure is such that concrete can be poured from the back of a wide area (foundation installation part), it is easy to place concrete during manufacturing, and a stable feeling is given to the entire product. Easy to install, transport, and handle products. The width of the low plate is large relative to the height of the product, and the front side is also a waterway floor plate. Since it is a concrete-made product or on-site concrete pouring, the product can be completely prevented from sliding against earth pressure and the product is stable even if it is not embedded in the riverbed. The presence of aquatic plants on the waterfront of the side wall of the fish floor BOX not only serves as a feeding ground, playground, and hiding place for underwater flutter, but also as a peaceful river bank or waterway that provides greenery to humans. There is. 5. Fish-shell BOX through hole for fish and shellfish 6. Lower part and lower part slab 4-1. Since the step between and has a structure that can contain mud or small gravel, it can provide a better habitat for habitat fish and shellfish, and is particularly suitable for loach habitat. Although it is a soil retaining product on the slope, it has a structure that does not allow the bed to be rooted, and has a low plate width that is wide relative to the product height, and the slab and joint rebars are exposed according to changes in the bed width or channel width. B. Width or front floor slab to build a channel width B. It is designed to be easy to join.

Further, even if there is a change in the riverbed width or the waterway width, it is sufficient to change the floor slab product or the locally cast concrete without changing the complicated side wall parts, and the conventional product can be used. Or, compared with the construction method, the cost of formwork can be greatly reduced and the local construction is easy.

In addition, FIG. Figure 9. As described above, the lower part slab 4-1. And the sky plate 4-2. Is a drainage box, the underwater toe small wall is eliminated by a partition of the formwork, and a double-cavity BOX is provided between the rear retaining wall and the front decorative wall. The vertical through-hole 17. It is also possible to easily manufacture a gravity-type rooting foundation block of a stacking block, which can be connected and integrated with concrete in the construction extension direction.
