It is assumed that the artificial grass piece stands on the surface of the base material layer. In this case, the holding length of the artificial grass fiber by the base material layer is 3 [m
m] to 7 [mm], or even about 10 [mm], but the base material layer is compressed when sand is sprinkled on it, or the base material layer is sagged due to the use of an artificial grass structure, etc. Therefore, the length may be longer depending on the material and structure of the base material layer and the application of the artificial grass structure. However, ordinary because too long to the base layer becomes too thick and extent 50 mm. For artificial grass like this

2 〕〜３００〔ｇ／ｍ2 〕が目安となる。In terms of the material of the base material layer,
An example of the base material layer is mainly cotton. When the base material layer is mainly composed of cotton, it is convenient to have a high cotton density in order to hold down weeds and seeds with the base material layer, but the base material layer suppresses water movement from below. In order to suppress the germination of weed seeds and the growth of weeds in the sand layer, it is convenient that the cotton density is low and the voids are large. Considering these balances in consideration of weed control, and in consideration of compression of the base material layer by sand and settling with the use of the structure,
For example, the cotton is added to the base material layer at 200 [k 2 / m 2 ].
When the uniform distribution surface load of [g] is applied, the thickness of the base material layer is 3 [mm].
It is possible to use it in a state of about 7 mm or about 3 mm to 10 mm. Moreover, in order to prevent the base material layer from receiving sand weight and from becoming too thin and hard by use, a weight per unit area of 500 [g / m 2 ] is used for 1 [m 2 ] per base material layer. It is conceivable to use cotton that can make the thickness of the base material layer 3 [mm] or more when an evenly distributed surface load of 200 [kg] is applied. Looking at the weight per unit area, it is not limited thereto, but is 50 [g / m 2 ] to 50
0 [g / m 2 ], more preferably 100 [g / m 2 ] to
300 [g / m 2 ], more preferably 200 [g / m 2 ]

よく、例えば５０〔mm〕程度まで考えられる。In any case, when the base material layer is mainly composed of cotton, the base material layer is sandwiched between two or more cotton layers which are vertically stacked and the cotton layers which are vertically adjacent to each other. A flexible reinforcing sheet is included, and the upper and lower cotton layers adjacent to each other with the reinforcing sheet in between are examples in which cotton fibers are entangled and connected to each other. Examples of such a reinforcing sheet include a flexible net-shaped reinforcing sheet and a flexible film made of a synthetic resin such as polyethylene. Further, in addition to or instead of interposing the reinforcing sheet between the adjacent cotton layers, the reinforcing sheet is laminated above, below or above and below the cotton layer, and the whole is deformed or collapsed by a connecting means such as a thread or staple. It is also conceivable to connect so as to sufficiently suppress the breakage. In any case, such a reinforcing sheet is for suppressing deformation, breakage, shredding, etc. of the cotton layer, but for suppressing germination and growth of seeds of weeds, it is possible to suppress water migration from below as much as possible. It is desirable to adopt, and for that purpose, a film made of a synthetic resin film that is not water-permeable by itself is more suitable. The base material layer does not need to be formed mainly of cotton, and is made of synthetic resin and is flexible, more preferably has high elasticity, preferably has poor water permeability, and preferably has water impermeable thickness of 3 [mm. ] The case of the above sheet can also be exemplified. In this case, the thickness of the base material layer may be 3 [mm] to 7 [mm], or even about 10 [mm], considering the holding length of the artificial turf fiber by the base material layer. It may be compressed when sand is sprinkled on it, or may be thicker depending on the application of the artificial turf structure, for example, up to about 50 mm.

For example, for example, a three-dimensional network structure having a large number of voids into which sand can enter and having shape retention and elasticity is laminated on the base material layer, and the fiber for artificial turf is provided with the three-dimensional network structure and An artificial turf structure in which the artificial turf piece is erected on the three-dimensional mesh structure by being woven over both layers of the base material layer is also conceivable. In addition, a three-dimensional network structure having a large number of voids and having shape retention and elasticity is laminated on the base material layer,
A sub-base material layer is laminated on the three-dimensional mesh structure, and the artificial grass fibers are woven over the sub-base material layer, the three-dimensional mesh structure and the base material layer to form the artificial material on the sub-base material layer. An artificial turf structure in which turf pieces are upright is also conceivable.

Such an artificial grass structure employing a three-dimensional mesh structure is advantageous as an artificial grass structure for a throwing stadium. In addition to this, the artificial turf structure adopting the three-dimensional mesh structure can be laid on a tee ground of a golf course or the like for use.

The network structure can provide voids that block the movement of water from above and below, whereby growth of weeds under the base material layer, seed germination, etc. can be sufficiently suppressed, and it can be spread on the sub-base material layer. The sand becomes dry, and the germination and growth of the seeds of weeds dropped or mixed in the sand can be suppressed.

きる。The sub-base material layer is also made of, for example, cotton as a main component, or is made of a synthetic resin, which is flexible and more preferably highly elastic, and preferably has poor water permeability, preferably a water impermeable sheet. It is possible to do it. The thickness of the sub-base material layer may be smaller than that of the base material layer. In terms of material, when the base material layer is mainly made of cotton, the sub-base material layer is also made mainly of cotton. When is formed of the above synthetic resin sheet, the sub-base material layer may be formed of the same synthetic resin sheet.

Laying on the throwing ground G of the athletics stadium, 2 artificial grass pieces
Sand can be sprinkled between 1 and can be used for spear throwing competitions, etc., and the spear thrown by the athlete can pierce this structure A or pierce the structure A and pierce the ground G below. . The amount of sand depends on the desired amount of protrusion of the artificial grass piece 21 from the sand S, the desired thickness of the sand S layer, and the like.
When the layer is about 15 [mm], sand may be sprinkled at a rate of about 30 [kg] per 1 [m 2 ]. In the illustrated example, the protruding amount of the artificial grass piece 21 from the sand S is about 5 mm.
