[Problems to be solved by the invention]
A large number of continuous filaments disclosed in Japanese Patent No. 9186 and Japanese Patent Application Laid-Open No. 11-247060 are fused and bonded to each other to be integrated, and are formed into a mat-like shape having a certain thickness as a whole with irregularities. Conventionally, the reticulated body has been used for revegetation work by covering the soil, so there is no need to particularly enhance the compression resistance in the thickness direction, and the above-mentioned earth pressure is applied, and the compressive stress is always applied in the thickness direction. , And in the development of drainage materials that require rapid discharge of
Initially, we responded by increasing the amount of filaments and producing a more dense mesh, but at the same time it was expensive in terms of cost, the weight of the product was heavy, and the handleability was poor due to the loss of bendability. There is an inconvenience that it becomes extremely poor, and there is a demand for a net that is lightweight, can be bent, and has excellent pressure resistance. Currently, energy-saving effects that can reduce cooling costs by covering with soil and natural appearance can be produced by planting vegetation, attracting attention to rooftop greening of buildings, and various greening materials have been developed. However, there has been no vegetation base material with excellent soil retention that can sufficiently cope with, for example, a steep portion of the embankment.

According to the present invention, the behavior of a conventional mesh under compression in the thickness direction is observed, and a large number of continuous filaments connecting the upper and lower horizontal planes of the mesh are fused and bonded to each other. As the number of filaments on the side wall formed by the mesh increases, the compressive stress of the mesh increases, and the side wall has two oblique sides in a triangular cross section having one ridge line. When the bottom portion corresponding to the apex portion) is fixed by a flat body such as a nonwoven fabric and the mesh is restrained from spreading, it is found that the mesh has a large resistance to compression in the thickness direction as a mesh. These have been studied in detail and arrived at the present invention.

In the reticulated body 19 illustrated in FIG. 6 according to another embodiment of the present invention, the side wall portion composed of the reticulated material has a dense reticulated portion 26.
When a net-like body is installed on an inclined surface as illustrated in FIG. 7 and used as a soil holding material that is covered with soil 30 or the like and greened, the coarse net-like portion is filled with soil. The dense net-like portion is easy to prevent the soil from flowing out, and is particularly suitable as a soil holding material on a slope. As the mesh body, when a mold 15 having a horizontal triangular prism convex portion cut in a direction perpendicular to the traveling direction illustrated in FIG. 5C is used, in the mold, a continuous filament is formed by advancing the triangular prism of the mold 15. Since the main surface is deposited mainly on the surface facing in the direction and the other surface has a smaller amount of deposition than the former surface, it is possible to easily form nets having different densities on the side wall portion.

According to one aspect of the present invention, the cross-section of the net-like body has a shape in which triangles are connected horizontally, and at least one side thereof is formed of a flat body such as a nonwoven fabric.
The pressure resistance is significantly improved. In addition, since the mesh is composed of continuous filaments of a thermoplastic resin, it is bulky, has excellent air permeability and water permeability, has a very large porosity, is lightweight, and is capable of being folded.
The handleability is excellent. Another reticulated body for the purpose of retaining the soil is such that it is easy to fill the soil into the mesh, which has been difficult to fill the soil with the above-described reticulated body, and that the inside is closed. Since there are no hollows and the generation of unfilled portions is suppressed, the amount of soil retained can be significantly increased even in the case of a net having the same thickness, which is suitable as a rooftop greening material for buildings. According to the present invention, a versatile net can be obtained.

By forming a net-like material, a non-woven fabric, a flat body that can be selected from a net or a film is placed thereon, and the flat body is pressed on the mold using a pressure roll from above. In the method for manufacturing a mesh body in which the flat body is fixedly joined to the mesh body, the vertex portion of the horizontal triangular prism protrusion is cut parallel to a mold plane and chamfered, so that the mesh body has a thickness that In cross section In the shape of a ridge, a plurality of ridges and grooves continuous in one direction are alternately formed, and the flat body is fixedly joined to one surface of the mesh, and the ridge has a bottom side in a cross section in the thickness direction. It is composed of the above-mentioned flat body, and the other hypotenuse 2
A method for manufacturing a net-like body, characterized in that a triangular cross-section structure whose sides are formed by said net-like material is formed.

10. A large number of continuous portions made of a thermoplastic synthetic resin on the other surface of the net-like material according to claim 9, wherein the flat body is fixedly joined to one surface of the net-like material, and the other surface of the mesh body is not bonded to the net. The filament is spun or coated with an adhesive, another flat body is placed on the filament, and the other flat body is pressed on the net using a pressure roll from above. A method for manufacturing a mesh body, wherein a flat body is fixedly joined to one surface, and the flat body is fixedly joined to both surfaces of the mesh.
