DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial lawn used by spraying earth and sand.

[0002]

2. Description of the Related Art Artificial turf is made by tufting a plastic tape yarn as pile yarn on a base cloth, and is used on porches, poolsides, grounds of golf courses and baseball fields, etc. Is constructed by spraying earth and sand on the pile surface and filling the pile layer.

[0003]

The artificial turf to be constructed on the ground is not particularly different from the artificial turf used without spraying earth and sand on a veranda, a poolside, etc., and the pile length is 15 to 25 mm. The pile protrudes rigidly from the base cloth like a brush, and when filling the pile layer with soil, an amount of soil equivalent to the thickness of the pile layer, approximately the same as the pile length, is sprayed on the pile surface. Will do.

[0004] However, 15 to 15
Even if the pile surface is sprinkled with earth and sand to make it 25mm thick,
Since the pile is rigid and upright like a brush, the scattered earth and sand only forms a 15-25 mm thick sedimentary layer on the pile layer, and if it is scattered just like that, it will be beautiful between the piles Do not enter.

[0005] Therefore, the earth and sand is rubbed between the piles while being stirred while discharging water. At this time, the earth and sand is repelled by the repelling force of the oscillating pile, and the pile is densely brought to the root of the pile easily. It cannot be filled.

For this reason, a method has been adopted in which the scattered and laminated earth and sand is rubbed to some extent into a pile layer, left as it is for several days, and when the earth and sand has naturally settled down, the earth and sand is again sprayed and rubbed. Since the work is performed several times, it cannot be constructed in a short time.

[0007] An artificial lawn constructed on a golf course tee ground is used by piercing a tee.
Since the length of piercing of the stay is generally 30 to 40 mm, in order to pierce the pile layer of 15 to 25 mm and pierce deeply, the insertion hole is finely formed in the base cloth for locking the pile. It must be left open, and it cannot be used as a ground just by filling artificial grass with earth and sand.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an artificial lawn which is easy to fill a pile layer with earth and sand and can be used as a ground without making a hole in a base cloth. The objective is to avoid costly improvements.

[0009]

An artificial grass 1 according to the present invention is provided.
3 is constructed by tufting a plastic tape yarn as a pile yarn on a base cloth 11 and having a pile length (h) of 3;
0 mm or more, the thickness (t) of the pile layer 16 is 5 mm or more and 70% of the pile length (h) when the pile 14 is pushed down by applying a load of 10 g per 1 cm ² to the pile surface and pressing. (T （h ≦ 0.7) and the pile layer 16 is filled with earth and sand 17 and the pile 14 is raked until the pile tip 18 is exposed on the surface of the pile earth and sand mixed layer 19. It is characterized by the following.

The reason why the pile length (h) is set to 30 mm or more is to make the pile 14 easily fall down, so that the sediment 17 deposited on the pile 14 can easily come into contact with the base cloth 11 and, as such, fall. This is because the pile 14 embedded in the soil 17 is easily caught by the tip of a rake or the like that stirs the soil 17 and is easily agitated on the surface of the pile-sand mixed layer 19. ) Should be about 40 to 100 mm, and generally about 50 mm.

The pile length (h) when the thickness (t) of the pile layer 16 when the pile 14 is pushed down is extended.
Is set to 70% or less because the gap between the piles in the pile layer 16 is increased, and the sediment 17 to be stirred is inserted between the piles, so that the pile 14 and the soil 17 are uniformly mixed, and each pile fiber The book is held by the earth and sand 17 and vertically raked, so that the pile tip 18 is uniformly scattered and exposed on the surface of the pile earth and sand mixed layer 19 so as to give a view of burning natural grass of young grass. For this purpose, the thickness (t) of the pile layer 16 in the pushed-down state is set to 20 to 50% of the pile length (h), and preferably 3%.
It is good to be about 0%.

The pile layer 1 in the pushed down state
The reason why the thickness (t) of 6 is 5 mm or more is that if the pile basis weight is too small, the pile 14 falls down and adheres to the base cloth 11 when soil and sand 17 are deposited, making it difficult for the rake or the like to catch on the rake. Pile 14 and earth and sand 1
This is because it becomes difficult to mix 7 uniformly.

When a load of 10 g / cm ² is applied to measure the thickness (t) of the pile layer 16 in the pushed down state, the sediment 17 is deposited so that the lamination thickness corresponds to the pile length (h). In this case, the pile 14 is easily collapsed so that the thickness (t) of the pile layer 16 becomes half the pile length (h), and the pile layer 16 is made bulky so that the earth and sand 17 can easily fit between the piles. In order to

The thickness (t) of the pile layer 16 when the pile 14 is pushed down in such a manner is set to 5 mm or more and 70% or less of the pile length (h) (t ÷ h ≦ 0.7). The weight of the pile may be adjusted according to the thickness (d) of the pile 14 and the toughening density (stitch interval (S) and gauge interval (G)).

[0015]

The artificial turf 13 according to the present invention has the following advantages. The pile 14 is easily hooked, and the pile 14 is easily scratched until the pile tip 18 is exposed on the surface of the pile earth / sand mixed layer 19.

(2) Since the pile 14 is easy to bend when the pile length (h) is 30 mm or more, the soil 17 is not repelled when it is raked up, and the soil 17 enters between the piles and is easily mixed with the pile 14.

(3) Since the thickness of the pile-sand mixed layer 19 is equal to or more than 30 mm corresponding to the pile length (h), the tap-up becomes easy, and the insertion hole in the base cloth 11 is finely formed when the pile is applied to the tail gland. No need to open.

(4) Since the pile layer 16 becomes extremely bulky, even if the pile length (h) is 30 mm or more, the pile length (h) is 15 to 25 mm and the conventional artificial turf densely tufted. Also, the pile basis weight can be reduced, and thereby the cost of the artificial grass 13 can be reduced.
