Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a civil engineering unit used for river protection, shore embankment and road slope protection. 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. Another object of the present invention is to provide a unit for a civil engineering structure. According to the present invention, in order to achieve the above object, a plurality of natural stones are laid and arranged on a wire mesh or mesh superposed on the upper surface of a suction prevention sheet. In this state, the plurality of natural stones, the wire mesh or mesh, and the suction-prevention sheet are integrally formed with an adhesive, and each natural stone is an intersection at which line portions of the wire mesh or mesh intersect. Each of the natural stones is set so as to be positioned at the top, and the adhesive is set to be positioned at the intersection with respect to each of the natural stones. As described above, the unit for civil engineering construction according to the present invention has a structure in which a plurality of natural stones are laid out on a wire mesh or mesh superposed on the upper surface of the suction prevention sheet. Since the natural stone, the wire mesh or mesh, and the suction-preventing sheet are integrally formed with an adhesive, the adhesive bonds the natural stone to the wire mesh or the mesh, and passes through the mesh of the wire mesh or the mesh. Leaching is performed on the lower sheet for preventing suction, and natural stone is integrated with the sheet for preventing suction and the wire mesh or mesh. Since the natural stone is thus integrally formed with the wire mesh or mesh, the unit for civil engineering construction of the present invention has a flexible structure and easily adapts to the shape of the slope, and has a natural slope. A revetment can be created, and the construction of curved surfaces, especially at the shoulders and bottoms, 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. In addition, since the mesh or wire mesh has a suction-preventing sheet integrated on the lower surface thereof, it is possible to prevent the adhesive material from flowing out during manufacturing, and the suction-preventing sheet is integrally formed during construction. The performance is improved. Further, when the revetment is constructed with the civil engineering building unit of the present invention, the natural space between natural stones becomes a habitat for fish, aquatic insects, and the like, and the space between the natural stones is filled with earth and sand to provide aquatic organisms and the like. A natural revetment will be constructed where plants can grow and fireflies can live. DETAILED 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 non-woven fabric. A wire mesh or mesh 2 that is hardly corroded is layered 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. 1 is formed as a unit A for civil engineering structures integrally formed (see FIGS. 1 to 4). Note that the mold 4 may be omitted. The civil engineering building unit A is laid on a slope as shown in FIGS. 5 and 6, and the wire mesh or mesh 2 is bent so as to conform to the shape of the laying surface, and is adjacent to the other. The wire mesh or mesh 2 is connected by an anchor 6 such as a skewer or a connecting coil 7 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 net or mesh 2 of a plurality of units for civil engineering construction A laid on the slope is horizontally bent and vertically adjacent to each other. The filling stone or earth and sand 9 is loaded between the 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. As described above, the unit for civil engineering construction according to the present invention has a plurality of natural stones laid on a wire mesh or mesh superposed on the upper surface of the suction-preventing sheet. Since the natural stone, the wire mesh or mesh, and the sheet for preventing suction are integrally formed with an adhesive, the adhesive passes through the mesh of the wire mesh or mesh, and as a result, the sheet for preventing suction. The wire mesh or mesh and the natural stone are integrated, and the revetment having a natural slope can be constructed by the flexibility of the wire mesh or mesh, and particularly, the curved surface construction of the shoulder portion and the bottom portion 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 no boulders or the like and the wire mesh or the mesh is not damaged. 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.
