Abstract

PURPOSE:To facilitate construction of slopes in revetment works without disturbing natural ecosystem by using natural stone wire netting. CONSTITUTION:After a wire netting or a corrosion-resistant mesh 2 is laid over the surface of a suction-preventing sheet 1, cylindrical forms 4 in shapes corresponding to natural stones 3 are laid thereon. Adhesives 5 are applied to the natural stones 3, and the wire netting or the mesh 2 are formed integral with the natural stones 3 over the suction-preventing sheet 1, and a flexible natural wire netting for protecting ecosystem is formed therefrom. Therefore, natural slope can be easily provided by flexibility of the wire netting or the mesh 2 to construction of slopes in revetment works.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural stone wire net for protecting ecosystems used for river bank protection works, coastal dike works and road slope protection works.

[0002]

2. Description of the Related Art Conventionally, in the case of this type of construction, the slope was covered with a cover concrete, a concrete block or a natural stone.

[0003]

The above-mentioned prior art requires a great deal of time and effort for construction, and is not particularly easy to construct at the shoulders and the tails. In addition, since the surface is covered with concrete, aquatic organisms and plants cannot grow, which disturbs the ecosystem, and there is a risk that sloped natural stones and concrete blocks will be washed away.

The present invention has been proposed in view of the above-mentioned problems of the prior art. The object of the present invention is to improve the workability and significantly improve the durability without disturbing the natural ecosystem. The point is to provide natural stone wire nets for ecosystem protection.

[0005]

In order to achieve the above object, the natural stone wire net for ecological protection according to the present invention has a plurality of natural stones laid on a wire net or mesh that has been polymerized on the upper surface of a sheet for preventing suction. The natural stones are arranged side by side, and an adhesive material is layered on the lower portion of each natural stone, and the natural stone, the wire mesh or the mesh, and the suction-prevention sheet are integrally formed through the adhesive material.

[0006]

As described above, the natural stone wire net for ecological protection according to the present invention, as described above, polymerizes the wire net or mesh on the upper surface of the sheet for preventing spillage and lays a plurality of natural stones on top of each other. 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 prevention sheet at the lower part thereof, and thus the suction prevention sheet and Natural stones are integrated like the wire mesh or mesh.

Since the natural stone is integrally formed with the wire net or mesh in this way, the natural stone wire net for ecological protection of the present invention has a flexible structure and is easily adapted to the shape of the slope. It is possible to construct a revetment with a steep slope, and in particular, it becomes easy to construct curved surfaces on the shoulders and slopes. Further, since the natural stone is reinforced through the wire mesh or mesh, the natural stone can be prevented from flowing away, and can be easily integrated by connecting the wire mesh or mesh, and a strong revetment can be constructed.

Further, the mesh or wire net is integrally laminated on the lower surface thereof with a suction-preventing sheet, so that the run-out of the adhesive is prevented at the time of production, and the suction-preventing sheet is integrally molded at the time of construction. , Workability is improved. Furthermore, when a revetment is constructed with the natural stone wire net for ecological protection of the present invention, the natural space between the natural stones becomes a habitat space for fish, aquatic insects, etc., and by filling the space between the natural stones with earth and sand. A natural revetment that allows the growth of aquatic organisms and plants, and where fireflies can inhabit.

[0009]

The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 is a suction-prevention sheet made of woven or non-woven fabric, and a wire mesh or mesh 2 that is resistant to corrosion is layered on the upper surface of the sheet 1, and a plurality of natural stones 3 are laid on it. Same as each natural stone 3 and the wire mesh or mesh 2
And a soft elastic cylindrical mold 4 is interposed between the mold 4 and
For example, an epoxy resin-based adhesive material 5 is filled therein, and the adhesive material 5 penetrates the mesh of the wire mesh or mesh 2 to form the natural stone 3 and the wire mesh or mesh 2, as well as the sheet 1 for preventing suction. The integrally formed natural stone wire net A for protecting the ecosystem is configured. (See FIGS. 1 to 4) The mold 4 may be omitted.

The natural stone wire net A for protecting the ecosystem is laid on the slope as shown in FIGS. 5 and 6, and at this time, the wire net or the mesh 2 is bent so as to adapt to the shape of the laying surface.
Further, adjacent wire nets or meshes 2 are connected by anchors 6 or connecting coils 7 such as skewers made of rebar. The soil is replenished in the spaces between the natural stones 3 to capture the river soil and promote the restoration of natural greening.

In FIG. 6, 8 is a rubble stone. FIG. 8 shows another embodiment of the present invention, in which the upper ends of the wire nets or meshes 2 of the multi-tiered natural stone wire net A for ecological protection laid on the slope are bent horizontally and are vertically adjacent to each other. A filling stone or earth and sand 9 is filled between the horizontal wire nets or meshes 2. Since the illustrated embodiment is configured as described above, the space between the natural stones 3 becomes a habitat for fish and insects, 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 built that is capable of allowing fireflies to live.

[0012]

As described above, the natural stone wire net for ecological protection according to the present invention has a plurality of natural stones laid side by side on the upper surface of the wire mesh or mesh polymerized on the upper surface of the sheet for preventing spillage. Since the adhesive is layered on the lower surface of the same, the adhesive penetrates through the mesh of the wire mesh or mesh, and as a result, the sheet for preventing suction and the wire mesh or mesh and natural stone are integrated, and the wire mesh or mesh Due to its flexibility, it is possible to construct a revetment with a natural slope, and especially the curved surface construction of the slope shoulders and slope tails is easily performed.

Further, the natural space between the natural stones becomes a habitat for fish and insects, and by filling the space with earth and sand, aquatic creatures and plants can be inhabited and a natural revetment where fireflies can inhabit can be provided. In addition, since it is integrated with a wire mesh or mesh, the size can be freely adjusted, and it can be stored in a roll shape during transportation and storage, so it can be stored without taking up space and is easy to transport.

Further, since it is reinforced by the wire mesh or the mesh, the natural stone is not washed away, and the wire mesh or the mesh can be easily integrated,
A strong revetment can be constructed. Furthermore, according to the present invention, since the surface is covered with natural stone, it does not damage the wire mesh or mesh due to boulders, etc., and in particular, zinc plating etc. on the wire mesh or mesh surface does not peel off, and it is durable. The property is greatly improved, it can be a semi-permanent sea wall, and it is easy to lay it by making it into a roll-shaped product,
Since the construction area is large at one time, it is possible to carry out mechanical construction, and it is possible to save considerable labor.
