DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a concrete block in which unit blocks are laid adjacent to each other.

[0002]

2. Description of the Related Art Conventionally, in concrete revetment works,
A concrete block having a smooth plane is laid adjacent to the slope. Since the revetment is laid with concrete, it has an artificial appearance and has a problem of damaging the natural environment. Therefore, new revetment works adapted to the natural environment are required for river revetment works.

[0003]

In recent years, with the widespread use of concrete revetments, the ecosystem of rivers has changed, and there is a tendency for creatures such as fireflies, butterflies, and dragonflies to decrease. Therefore, there is increasing momentum nationwide to protect creatures such as fireflies, butterflies, and dragonflies, and the Environment Agency has selected the "Hometown Ikimono Sato 100 Selections". In addition, it has become necessary for river revetments to have conditions for growing these creatures. The applicant has prepared an artificial megalith with natural stones arranged on the surface.
No. 03541. According to this, since natural stone is arranged on the surface, unlike a concrete block, it has an appearance adapted to a natural environment. However, since the surface of this artificial megalith is solidified with natural stone and concrete, there is a problem that plants cannot be planted , and also a problem that the growth conditions of insects are not satisfied.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a concrete block having an environment in which plants can grow and pupae of insects can live.

[0005]

According to a first aspect of the present invention, there is provided a concrete block in which a plurality of unit blocks are laid adjacent to each other, wherein the unit blocks are fixed so that a large number of natural stones and the like protrude from the surface. body and the planting unit for the surrounded by natural stones or the like the soil provided is deposited on the surface of the block body, lower than the upper end communicating with the planting unit through said block body is large diameter It has a feature in that it is composed of a communication part.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a concrete revetment will be described below with reference to the drawings.
First, in FIG. 3, a concrete block 1 has a large number of unit blocks 2 laid adjacent to each other. The unit block 2 has a notch 3 formed in the outer peripheral portion. These unit blocks 2 are arranged so that the notches 3 coincide with each other, and natural stones 5 such as boulders are arranged in a space 4 formed by the plurality of notches 3. Each unit block 2
They are connected to each other by a connecting member 7 such as a connecting anchor reinforcing bar 6 and a shackle.

Next, the unit block 2 will be described with reference to FIG. The block main body 11 fixes a large number of natural stones 12 such as cobblestones so as to protrude from the surface.
The protrusion amounts of the natural stones 12 do not necessarily have to be the same size, and may be irregular. The natural stone 12 is not limited to a cobble stone, and may be, for example, a pseudo stone in which high-grade natural stone is combined with cement or mortar.

[0008] Then, the surface of the block body 11, planting unit 13 that the soil is deposited is formed on surrounded by the natural stones 12 protruding portion. Planting unit 13 contacts a plurality of natural stones 12 above, may be filed upper end, in a narrow state. Communicating part 14 penetrates the block body 11, the upper end is communicated with the planting unit 13. The communication portion 14 has a larger diameter at the lower end than at the upper end. The lower end surface of the block body 11 is provided with a suction prevention member 8 such as a mat.

Next, the operation of the above configuration will be described with reference to FIG. Deposited soil planting unit 13 fills the communicating portion 14 are sequentially lowered. Then, the water sucked up from the lower end of the rainwater or the block body 11, planting unit 13 and the communicating portion 14 is maintained in a wet state.

[0010] The seeds of the plant G is, take root in the planting unit 13, flourish to create a shade in natural stone 12 as shown in Figure 1. As a result, the surface of the natural stone 12 does not dry and the moist condition is maintained, so that moss H and the like grow on the surface. This moss H
Is suitable for fireflies to lay eggs. Then, when the frog egg of fireflies, to grow in water, landed on the night of warm April rain becomes a pupa in the wet soil of the planting unit 13 and the communication unit 14, which emerged in June . In addition, plant which sank under water surface W
Planting unit 13, soil excluded performs the function of reef fish F
Habitat is improved.

According to the above embodiment, the following effects are obtained. 1. Since the natural stone 12 is made to protrude from the block main body 11 and the amount of protrusion is different, even if a large amount of water flows, the flow velocity can be suppressed, and a flood disaster can be prevented. 2, natural stone 12 from the block body 11 protrudes, moreover, since the plant G is flourish planting unit 13, are adapted to the natural landscape. 3, since the water is supplied through the communicating portion 14 to the planting unit 13, always the soil can hold wet state.

[0012] 4, because it satisfies the conditions for inhabiting creatures such as insects, for example, the following firefly growth conditions, it is used for revetment of rivers and "Hometown Ikimonosato" selected by the Environment Agency.
Can contribute to the realization of "Fireflies habitat conditions" a, environment of sunbeams b, pupa emerges, there is always moist soil c, moss H grows for firefly spawning

[0013] 5, planting unit 13, since they are formed continuously with each other so as to comb enclose the natural stones 12, the spring is a root of a plant, so take the form in which these roots are linked to natural stone The role of revetment can be strengthened. 6, since the natural stone 12 protrudes from the block body 11, the boundary line of the unit block 2 is difficult to see from the outside, and since the natural stone 5 is arranged in the space 4 formed by the cutout 3, the unit The boundary of block 2 can be covered from the outside. 7. Since the lower end of the communicating portion 14 has a large diameter, the root of the plant G that has prospered does not come off even if it is pulled. 8, planting unit 13, which sank in the water, plays a function of the reef,
The habitat of fish F is improved.

[0014]

According to the first aspect of the present invention, in a concrete block in which a number of unit blocks are laid adjacent to each other, a block body in which the unit blocks are fixed so that a large number of natural stones and the like protrude from the surface is provided. and planting <br/> portion provided on the surface of the block body said surrounded by natural stones such as soil deposited, the lower end than the upper end communicates with the planting unit through said block body of large diameter Since it is composed of a communication part, plants can grow on the surface of the concrete block, and an environment in which insect pupae can live can be formed, and the natural environment can be restored. water can be supplied to the planting unit through section, the roots of luxuriant plants G is for an effect that is not also pulled exit.
