技場”を開発した。Athletic stadiums made of natural soil such as native clay or Anzuca (hereinafter simply referred to as soil stadiums) have problems such as poor water drainage and time-consuming maintenance, as well as sports stadiums made of natural soil such as clay and turf. In order to improve problems such as the tendency for the soles of shoes and balls to slip during wet sports stadiums, sprains caused by being hit by spikes, and abrasions caused by falls, the applicant has filed Utility Model Registration No. 1174248.
As disclosed in the invention of the No. 1 issue, in addition to soil such as river sand or sea sand, synthetic resin particles, wood powder such as sawdust, or relatively hard granular materials such as those used in Antukar are mixed into the grass grain of the artificial lawn. We have developed a so-called "sand-containing artificial turf athletic field" that is filled with one or more types of covering materials.

のに極めて近似した運動競技場として普及しつ\ある。In addition to the above, for example, to prevent the soil (mainly sand) filled in the artificial lawn from being compacted over time,
The technology of mixing organic granules with rubber elasticity such as comb chips with sand (Utility Model Publication No. 61-5371) provides an effective solution to the contradictory problems of water retention and drainage, and In order to prevent scattering, there are dozens of inventions and ideas, such as a technique (Japanese Patent Application Laid-Open No. 59-24006) in which the sand layer filled in an artificial lawn is composed of a lower layer of fine-grained sand and an upper layer of coarse-grained sand. doing. With the structure of the sand-containing artificial grass sports stadium according to these inventions or ideas, the problems with the soil sports stadium and the stadium made only of artificial grass described above can be effectively improved, and the performance and appearance are similar to those of the natural grass type. It is becoming popular as an athletic stadium that closely resembles a physical stadium.

ある。However, the athletic field made of artificial grass filled with sand is not without its problems. In other words, in order to achieve excellent ball bounce performance, surface sliding properties, drainage properties, and shock absorption properties, the sand to be filled in the stadium should be filled with consideration for compaction over time after construction. The artificial lawn is filled to a thickness of approximately 80 to 110% of the leaf length of the artificial lawn. Therefore, the whiteness of the sand stands out on the surface of the stadium, and the green of the artificial lawn, which is colored to resemble a natural lawn, is canceled out, and the surface may look like a mere sand-paved surface.

。Therefore, the present invention solves the above-mentioned problems and makes the green color of artificial grass stand out, making it look like natural grass +! To provide a construction method capable of efficiently constructing an athletic field made of artificial grass containing sand that resembles the surface of Stadium A.

人工芝生上に散布し、かつ震盪を加えつ\芝目内に充填
することを特徴とする。In order to solve the above-mentioned problems, the present invention constructs an artificial turf athletic field by spreading and laying an artificial turf on a substantially flat base and filling the grain of the turf with sand. When doing so, sand within the large diameter range of the particle size distribution range of the sand is colored green, the colored sand is sprinkled on the artificial lawn together with uncolored sand, and shaken. It is characterized by being filled into the grass grain.

するものである。That is, according to the construction method of the present invention, instead of simply coloring the sand to be filled into the artificial lawn in the same green color as the lawn, the large diameter sand within the particle size distribution range is colored green. At the same time, the colored sand was sprinkled on the artificial lawn together with the remaining non-colored sand, and the tips of the leaves of the artificial grass were shaken to cause the comparatively small diameter non-colored sand to settle to the lower layer. The colored sand with a target diameter is made to float to the surface layer.

ると、着色砂が表面上に目立ち過ぎて外観を損なう。As mentioned above, the grain size of the sand filled into the grass grains of an athletic field made of sand-containing artificial turf, as well as the filling thickness (amount), determines the athletic performance, sliding performance, and drainage performance of the completed stadium surface. It should be selected appropriately as it is closely related to impact absorption performance, etc. According to a preferred embodiment of the present invention, the sand contains 90% or more of sand with a particle size in the range of about 0.15 mm to 1.21 mm. It is prepared as follows. In addition, as shown in Figure 3 (A), among the sand (S) having the above particle size distribution, it is within the large diameter range including the upper limit, and corresponds to about 3%, preferably 5% by weight of the total amount. The sand (So) is colored green. In this case, if only too large diameter sand is colored, the colored sand will stand out too much on the surface and spoil the appearance.

動競技場が形成される。According to the construction method of the sand-containing artificial grass sports stadium according to the present invention as outlined above, the large-diameter sand with a predetermined particle size distribution is colored green, and this is mixed with the remaining uncolored sand. Then, use a suitable sand scattering device to spread the cough sand onto the artificial lawn that has been spread and laid on the base, add M to the tips of the leaves of the lawn, and fill it into the grass. Due to the shaking action, the uncolored sand, which is relatively small in diameter among the mixed sand, settles downward into the grass grain, and relatively large sand, which is colored in the same color as the artificial lawn, settles downward into the grass grain. Because the colored sand of the diameter floats to the surface and aggregates, the problem of the whiteness of the sand conspicuously conspicuous as in the case of sports stadiums made of sand-filled artificial turf using only uncolored sand is solved, An artificial grass athletic field is formed that is very similar in appearance and performance to the playing surface of the main turf layer.
