Description of the Related Art In recent years, for example, when constructing a tennis court, an artificial lawn with sand is widely used because the introduction cost and the maintenance cost are low and the feeling of grounding is relatively close to that of a natural lawn. Here, a sand-containing artificial lawn is one in which a large number of piles are planted on a planar base cloth, and a granular filler such as grain sand is filled between these piles by using a deck brush or a rotating brush. pointing.

参照：従来例３）を提案した。By the way, the artificial grass with sand is tampered with by spikes for competition, or the sand is solidified by the sand, the abrasion dust of the pile, ordinary dust, foreign substances, etc. entering into the spaces between the sand. There is a problem that the good ground feeling initially obtained is gradually deteriorated. In order to solve this problem, an artificial lawn has been proposed in which loop piles buried in the sand are planted in the base fabric and the elasticity of these piles maintains a good ground contact feeling ( Actual Kaihei 6-1
See Japanese Patent No. 405: Conventional Example 1). In addition, the applicant of the present application also
An artificial lawn athletic field filled with only elastic rubber chips between the piles (see JP-B-63-39725: Conventional Example 2) and a granular material layer such as vulcanized rubber between the piles,
An artificial lawn athletic stadium (see Japanese Utility Model Publication No. 64-6862: Conventional Example 3) having its surface layer formed of spherical particles such as glass beads was proposed.

る。However, in the conventional example 1, since the elasticity of the pile buried in the sand is relatively low, the elasticity of the pile deteriorates with the lapse of time, and a good ground contact feeling is maintained for a long time. There is a problem that you cannot do it. Further, in Conventional Example 2, although the elastic rubber chip has elasticity, since it is in the shape of a chip, the rubber chip comes out of the pile after long-term use, and as a result, a good ground contact feeling is lost. Further, in the conventional example 2, when performing a filling operation with a deck brush, a rotating brush, or the like, the elastic rubber chips are less likely to be filled between the piles and easily come out between the piles due to the characteristics of the elastic rubber chips having elasticity. That is, in Conventional Example 2, since the filling property of the elastic rubber chip is low, there is a problem that the filling work is troublesome.

There is. The present invention has been made to solve such a conventional problem, and an object thereof is to provide a sand-filled artificial lawn that can easily perform construction work and can maintain a good ground feeling for a long period of time. is there.

形状であってもよい。In order to achieve the above object, in the invention described in claim 1 of the present invention, granular fillers are laminated and filled so as to cover the elastic fillers filled between the piles. The artificial lawn containing sand is characterized in that the elastic fillers are formed in a shape such that the elastic fillers are cross-laminated with each other and voids are formed therebetween. In this case, as the material of the elastic filler, suitable rubber, vinyl, plastic or the like having elasticity and weather resistance can be adopted. Further, the shape of the elastic filler may be such that it can be cross-laminated so as to form voids.
A substantially cylindrical shape or the like can be adopted, or a twisted substantially band shape may be used.

になる。In the invention described in claim 1 of the present invention, the elastic fillers are cross-laminated to form voids therebetween. Therefore, the granular filler such as sand grains laminated and filled with the elastic filler may be tampered with by the spikes for competition, or the sand grains may solidify due to sand grains, pile abrasion waste, ordinary dust, foreign matter, etc. Also, the elasticity of the elastic filler is secured, and a good ground contact feeling can be maintained for a long time. Further, if the elastic filler is formed into, for example, a substantially columnar shape having a predetermined length, a substantially cylindrical shape, or the like, it is easy to get entangled with the artificial turf, so that the filling property and stability can be increased, and the filling work can be easily performed. Further, after the filling, the filling material is prevented from coming out from between the piles, and a good feeling of contact with the ground can be maintained for a long time.

In Comparative Example 4, the filling property of the elastic filler 15 was evaluated four times, the stability of the elastic filler 15 was evaluated x, the finished Gmax was 71, and the post-compacting Gmax was 76.

However, it is understood that the filling property of the elastic filler 15, the stability of the elastic filler 15, the Gmax after finishing, and the Gmax after compacting have been well-balanced and highly evaluated. In particular, when comparing Examples 1 to 5 with Comparative Example 4, the elastic filler 15 is significantly evaluated for its filling property and stability when the ratio of the length L to the diameter D is 3 or more. It turns out to be high.

場合、常に一定した条件を維持できる。That is, in Examples 1 to 5, in constructing the artificial lawn 10 containing sand, compared with Comparative Examples 1 to 4, the filling work of the elastic filler 15 and the granular filler 16 is easier. You can do it. In addition, in Examples 1 to 5, there is little change in the feeling of contact with the ground immediately after construction of the sand-containing artificial grass 10. For example, when the artificial grass 10 is used in a tennis court or the like, a constant condition can be maintained.

For example, the elastic filler may have any shape as long as it has a shape in which air gaps are formed between layers of the elastic filler, and may be a substantially prismatic shape such as the elastic filler 20 shown in FIG. Figure 2
The elastic filler 21 shown in (B) may be formed in a substantially sardine shape. Further, the elastic filler 22 shown in FIG. 2 (C) has a substantially band shape that is twisted. Even if these elastic fillers 24 are laminated one on top of the other, the surfaces do not come into close contact with each other, and voids can be formed between them.
