Abstract

(57) [Abstract] [PROBLEMS] To provide a concrete block that can constitute an environmental revetment that is good for the ecosystem without damaging the natural environment. SOLUTION: A saucer 3 is continuously provided on the inner bottoms of two inclined plates 1 and 2 which face each other, and a through hole 5 for a small bird a is formed in the front inclined plate, and an upper end edge portion thereof is formed. A vegetation cutout 6 was provided.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a concrete block for steep slope natural works applied to the construction of revetments and retaining walls.

[0002]

[Prior art]

 Conventionally, concrete blocks were laid and layered on the slopes of river banks and retaining walls.

[0003]

[Problems to be solved by the device]

 Therefore, the surface of conventional revetments and retaining walls is covered with concrete, which impairs harmony with the surrounding natural environment and disturbs the biological system such as rivers. The present invention has been proposed in view of the above-mentioned problems of the prior art, and its purpose is to be suitable for the growth of plants and the growth of birds, which is structurally stable without damaging the natural environment. The point is to provide concrete blocks that can form revetments and retaining walls.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the concrete block according to the present invention is provided with a saucer at the inner bottom portion between the opposing front and back inclined plates, and the front side inclined plate is provided with through holes for small birds to move in and out. In addition, a vegetation cutout is provided at the upper edge. According to the second aspect of the present invention, natural stones are layered on the outer surface of the inclined plate on the front surface side of the concrete block, and a reinforcing bar for fixing the block is projected from the rear surface of the inclined plate on the rear surface side.

[0005]

[Embodiment of device]

 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention shown in the drawings will be described. Reference numerals 1 and 2 denote a front side sloping plate and a back side sloping plate, which are provided in parallel to the slope of the revetment arranged at a distance from each other. On the surface of the front sloping plate 1, natural stones 4 are integrally layered to form a natural pattern that is in harmony with nature, and a through hole 5 through which a bird a enters and exits is formed. Part 6 is provided.

Reinforcing bars 7 for fixing the block are provided so as to project from the back surface of the back side inclined plate 2. Since the concrete block shown in the figure is constructed as described above, the block is laid in the vertical and horizontal directions of the slope, and by fixing it to the backfill concrete 8 on the revetment slope via the rebar 7, the block is attached to the slope. The concrete blocks can be integrally laminated and fixed, and by allowing small birds to enter and exit through the through holes 5 of the front-side inclined plate 1, the blocks can function as bird nests.

Further, since the tray 3 is provided at the bottom of the internal space between the front and back inclined plates 1 and 2, stones and soil 9 can be filled in the internal space even if the slope is steep. Therefore, it is possible to plant, and the plant b can grow to the outside from the cutout portion 6 provided in the front side inclined plate 1 and can green the block surface. Furthermore, by putting quarry stones 10 and earth and sand 11 in the inner space between the front and back sloped plates 1 and 2, it is possible to create an environmental revetment that is good for the ecosystem and to increase the weight of the revetment wall itself and stabilize it. The property is improved. In the figure, 12 is a top block that covers the top of the wall.

[0008]

[Effect of device]

 As described above, the concrete block according to the present invention has the saucer at the inner bottom of the front and back inclined slabs, so even if the slope is steep, the inner space between the front and back inclined slabs is filled with earth and sand and stones. The front sloped slab can be covered with vegetation and plants can grow to cover the front sloped slab through the cutouts provided at the upper edge of the front sloped slab. It can be used as a nest hole due to the entry and exit through holes, and as described above, it constitutes an environment friendly to the ecosystem together with the stones and earth and sand put in the space formed between the front and back inclined plates. It is possible.

According to the invention of claim 2, natural stone is layered on the outer surface of the inclined plate on the surface side, and the block surface has a natural stone pattern, so that a revetment adapted to a natural environment can be constructed. In addition, since the block fixing rebar is projected from the back of the inclined plate on the back side, the concrete block masonry structure can be integrated with the back-filled concrete through the rebar. The structural stability of the block masonry structure can be further increased by filling the space with cobblestone, earth and sand, etc. to increase the weight.
