DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural gauze mesh for protecting ecosystems, which is used for river revetment works, coastal embankment works, and road slope protection works.

[0002]

2. Description of the Related Art Conventionally, in this type of construction, the slope has been covered with sloped concrete, concrete block or natural stone.

[0003]

The above-mentioned prior art requires a great deal of labor for construction, and it is not easy to construct particularly at the shoulder and the bottom. In addition, since the surface is covered with concrete, aquatic organisms and plants cannot grow, disturbing the ecosystem, and there is a fear that natural stone or concrete blocks on slopes may be washed away.

[0004] The present invention has been proposed in view of the above-mentioned problems of the prior art, and its object is to improve the workability and greatly improve the durability without disturbing the natural ecosystem. It is to provide a natural stone wire mesh for ecological protection.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the natural gauze for protecting ecosystems according to the present invention comprises a plurality of natural stones on a wire mesh or mesh superposed on the upper surface of a suction-prevention sheet. The natural stone, the wire net or the mesh, and the sheet for preventing suction are integrally formed with the natural stone, and an adhesive is layered below the natural stone.

[0006]

The natural stone wire mesh for protecting the ecosystem according to the present invention is, as described above, a metal rope or mesh is superimposed on the upper surface of the suction-preventing sheet, and a plurality of natural stones are laid thereon. Since the adhesive is layered on the lower part, the adhesive adheres the natural stone to the wire mesh or mesh, and leaches through the mesh of the wire mesh or mesh to the suction-preventing sheet underneath, thus the sheet for preventing suction and Natural stone is integrated with the wire mesh or mesh.

[0007] Since the natural stone is thus integrally formed with the wire mesh or mesh, the natural stone wire mesh for protecting the ecosystem of the present invention has a flexible structure, and is easily adapted to the shape of the slope. A revetment with a steep slope can be created, and the construction of curved surfaces, especially at the shoulders and buttocks, becomes easier. Further, since the natural stone is reinforced via a wire mesh or a mesh, the natural stone can be prevented from flowing out, can be easily integrated by connecting the wire mesh or the mesh, and a strong seawall can be constructed.

[0008] Further, since the mesh or wire mesh is integrally layered with a suction-preventing sheet on the lower surface thereof, it is possible to prevent the adhesive material from flowing out during manufacturing and to form the suction-preventing sheet integrally during construction. The workability is improved. Furthermore, when the revetment is constructed with the ecologically protected plain stone wire mesh of the present invention, the natural space between natural stones becomes a habitat for fish and aquatic insects, and the space between the natural stones is filled with earth and sand. This forms a natural revetment where aquatic organisms and plants can grow and fireflies can live.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 denotes a suction-prevention sheet made of a woven or nonwoven fabric. A wire mesh or mesh 2 that is hardly corroded is overlaid on the upper surface of the sheet 1, and a plurality of natural stones 3 are laid thereon. A soft elastic cylindrical form 4 is interposed between each natural stone 3 and the wire mesh or mesh 2,
The same frame 4 is filled with, for example, an epoxy resin-based adhesive 5, and the adhesive 5 penetrates the mesh of the braid or mesh 2, so that the natural stone 3 and the braid or mesh 2, as well as the sheet for preventing suction. Thus, a natural gauze net A for ecological protection is integrally formed with the metal wire 1 (see FIGS. 1 to 4). The mold 4 may be omitted.

The natural stone wire mesh A for protecting the ecosystem is laid on a slope as shown in FIGS. 5 and 6, and at this time, the wire mesh or mesh 2 is bent so as to conform to the shape of the laid surface.
Adjacent wire meshes or meshes 2 are connected by an anchor 6 or a connecting coil 7 such as a skewer made of a reinforcing bar. Soil is replenished in the gaps between the natural stones 3 to capture river soil and promote natural revegetation recovery.
In FIG. 6, reference numeral 8 denotes rubble.

FIG. 8 shows another embodiment of the present invention, in which the upper end of each wire mesh or mesh 2 of a natural stone wire mesh A for protecting ecosystems, which is laid on a slope, is bent horizontally and vertically. A filling stone or earth and sand 9 is loaded between adjacent horizontal wire meshes or meshes 2. In the illustrated embodiment, the space between the natural stones 3 serves as a habitat for fish and insects as described above, and if the space between the natural stones 3 is filled with earth and sand, the growth of aquatic organisms and plants 10 can be improved. A natural revetment will be constructed where fireflies can live.

[0012]

As described above, the natural stone gauze for ecological protection according to the present invention has a structure in which a plurality of natural stones are laid on the upper surface of a mesh or mesh meshed on the upper surface of the suction-prevention sheet, and Since the adhesive is layered on the lower surface of the wire, the adhesive penetrates the mesh of the wire mesh or mesh, and as a result, the suction-prevention sheet, the wire mesh or mesh and natural stone are integrated, and the wire mesh or mesh The flexibility makes it possible to construct a revetment with a natural slope, and particularly, the curved surface construction at the shoulder and the bottom of the slope can be easily performed.

The natural space between the natural stones serves as a habitat for fish and insects, and by filling the space with earth and sand, a natural revetment is provided in which aquatic organisms and plants can inhabit and fireflies can inhabit. In addition, since they are integrated with a wire mesh or mesh, the size can be freely adjusted, and they can be rolled during transportation and storage, so that they can be stored without taking up space, and transportation is easy.

Furthermore, since the reinforcement is provided by the wire mesh or the mesh, natural stone does not flow off, and the wire mesh or the mesh can be easily integrated by connecting the wire mesh or the mesh.
Strong revetment can be constructed. Furthermore, according to the present invention, since the surface is covered with natural stone, there is a boulder or the like, so that the wire mesh or the mesh does not break down. The property is greatly improved, it can be used as a semi-permanent seawall, and it is easy to lay by making it a product processed into a roll.
Since the construction area is large at one time, machine construction can be performed, and significant labor saving can be achieved.
