Description of the Related Art On the surface of an artificial lawn laid on the ground of a stadium or the like, as described in Japanese Patent Laid-Open No. 3-125704, the appearance of the artificial lawn is approximated to that of a natural lawn, and the ball for ball games is bounced. For the purpose of making the soil natural, etc., a method of spraying sand, mineral powder, or plastic powder filler into the pile layer and filling it into the artificial lawn surface is adopted.

On the other hand, if the particle size is made coarse, it becomes difficult for the filler to fit in the pile layer.
First, a filler with a fine particle size is dispersed and filled, and then a coarse filler is filled, and the pile layer is composed of an upper layer with coarse filler and water easily seeping in, and a lower layer with fine filler and water retention effect. It is considered preferable to have a layered structure.

Providing drains vertically and horizontally increases the cost of ground work. Therefore, the present invention aims to simplify the ground construction by reducing the number of drainage ditch, and also to prevent water from pooling on the surface of the ground even if clogging occurs in the water-permeable holes of the base cloth of the artificial lawn.

In addition to flat yarns such as polypropylene, nylon, polyester, polyvinylidene chloride, etc., which have a flat cross section, split yarns in which slits are finely inserted in a plastic film are also included.
Various types of 000 denier are used. "Flocking interval" is also called "stitch" and back stitch 27
Means a gap between piles formed by one pile yarn 11 in one continuous direction, and the arrangement interval of pile yarns is also referred to as a "gauge".

することになる。In the present invention, when the distance between the piles (gauge stitch) is increased, the voids 22 surrounded by the open pile tips 20 and the left and right pile roots 21 are formed like a path covered with leaves. While being formed long along the pile row, the filler 14 having a large particle diameter can easily penetrate deeply into the pile root 21 due to the coarse pile density. As the particle size becomes coarser, the gap between the fillers also becomes larger, so that a large gap 23 in which water easily flows is formed in the lower layer portion 17, which can be formed along the pile row. The drainage channel 24 will be formed in the inside 13.

In No. 2, the base cloth 19 is exposed between the pile rows, and the appearance of the pile surface is not good, and at first glance it looks like a thing without commercial value as an artificial lawn.

はそのままセットされることになる。However, according to the prior art, since the particle size of the filler to be dispersed is small, the dispersed particles merely fill the space between the pile fibers.
When the coarse particles 14 having a size of mm or more are first inserted, the coarse fluid 14 spreads the pile fibers 25 of the pile root 21 like a wedge, and the pile fibers 25 are individually separated so that the pile tip 20 becomes extremely large. Hair will be bulky. Then, each pile (fiber) tip 20 that has been opened and divided into individual hairs
During this period, the piled particles 15 are inserted between them, so that the finely divided state of the pile tip 20 is set as it is.

16が出来上がることになる。As a result, on the ground surface 16 finished by spraying the filler, not only the base cloth 19 but also the pile root 21 having a coarse pile density and the drainage channel 24 formed in the lower layer portion 17 are formed.
Does not appear on the surface, and the pile (fiber) tips 20 are finely and uniformly dispersed to be mixed with the fine particles 15 to form a beautiful ground surface 16.
【0012】従って、本発明に係る人工芝生12は、パ

ではなく、却って付加価値の高いものとなる。Therefore, the artificial lawn 12 according to the present invention has a high pile density and the base cloth 19 can be seen through from the pile surface, but the commercial value is not lost by that, and the added value is rather high. Will be things.

4が出来なくなる。However, if the interval (g) between the pile rows is made wider than twice the pile length h, even if the pile 26 is bulkyly opened due to the hair-opening action of the coarse particles 14 that acts like a wedge. , Between the piles, a part not covered by the pile (fiber) tip 20 is formed along the pile row,
It will appear on the ground surface 16 as a shadow of the drainage channel 24, and most of the ground surface 16 will be covered with the fine particles 15, which makes it meaningless to lay an artificial lawn.
Further, if the pile length h is too short, it becomes difficult to divide the pile layer 13 into the upper layer 18 and the lower layer 17 by the fine particles 15 and the coarse particles 14, and the drainage channel 2 which is effective between the pile rows 22 is formed.
You can't do 4.

The specification is set from this point of view. In that sense, the pile length h should be at least 15 mm, and the pile row interval g (stitch gauge) should not be larger than 1.7 times the pile length h. Also, the pile areal weight must not be less than 300 g / m 2 .

になるようにすればよい。The drainage channels 24 are formed side by side on the left and right sides of the pile rows, and the pile rows in which the piles are arranged at regular intervals like comb teeth do not block the flow of water between the drainage channels. The drainage channel 24 may be formed in any one of the vertical and horizontal directions of the pile layer 13, and therefore, either the arrangement interval (gauge) of the pile yarns or the flocking interval (stitch) may be set to 8 mm or more.

When the pile layer thickness (pile length h) is 10 mm, the pile basis weight is 200 to 1000 g / m 2, and 70% by volume or more of the filler 14 to be packed in the lower layer portion 17 has a particle size of 2 mm or more. The coarse particles (14) are preferably used, and the filler 14 to be filled in the lower layer portion 17 includes the coarse particles (14) having a particle diameter of 5 mm or more.

The artificial lawn 12 can be finished by backing it with a backing agent 28 in order to firmly adhere the pile 26 to the base cloth 19, but in the present invention, since the drainage channel 24 is formed in the pile layer 13, in that case, It is not always necessary to form water-permeable holes in the cloth 19 to make the artificial grass itself 12 water-permeable.

The artificial lawn land surface 16 is formed in which no water can be collected without the provision of the above.
