Description

The present invention relates to a horse riding field, a soccer field, a baseball field, and other grounds for use in a sports field.

In recent years, the racetracks have been equipped with riding mats, etc., on paving stones with a predetermined crushed stone structure, and further mixed sand with wood chips, mixed sand with Shirakawa sand, palm fiber, and felt. It is formed by laminating mixed sand or the like.

However, mixed sand containing wood chips has good drainage and cushioning properties, but the wood chips are easily rotted, insects and molds are easily generated, and it is necessary to replace them every five years.
In addition, although the wash river sand has good drainage properties, it is easy for the horse ground to become hard and load the horse's feet, so regular maintenance is essential.

Furthermore, although the mixed sand containing palm fibers has good drainage and cushioning properties, the grip strength of the Baba mat is reduced due to deterioration of the palm fibers, and replacement is necessary before the palm fibers are spoiled.

Furthermore, the mixed sand with felt has good drainage and cushioning properties. Felt is a safe material for humans and horses and is also used in the Athens Olympics. However, since the grain size composition of Baba in each region is different, it is necessary to determine the blending amount of felt, and it takes time for Baba to adapt to the horse.

Therefore, as a result of prior patent search, Japanese Patent Laid-Open No. 2001-145787 and Japanese Utility Model Laid-Open No. 5-35.
The 881 gazette etc. were searched.
Japanese Patent Application Laid-Open No. 2001-145787 is in the form of bandits or ground meat of elastic chips having a specific gravity of 2.5, in which a dirt course of a racetrack is blended with a synthetic resin such as urethane or synthetic rubber and an inorganic powder material such as titanium oxide or barium sulfate. It proposes to mix the deformed ones to improve the horse's legging and not damage the horse's eyes.

Japanese Utility Model Laid-Open No. 5-35881 proposes to incorporate a fiber skeleton of a bulky nonwoven fabric into a racetrack. However, although the reinforcing effect of connecting the soil between the separated fibers is separated, a binder such as a water-soluble resin is used to exert the uniform reinforcing effect so that the fibers do not break in the soil. It was necessary to spray and maintain.

As a result, the ground drainage of Baba is good, the grass roots are entangled with felt tips and felt fibers, the turf is better settled, the cushioning is better, the kicking is less, and the Baba grip is also better It has been found that the maintenance supply of sand can be greatly reduced compared to the conventional method. In addition, since the felt chip and felt fiber are waste materials, the cost is low, and it can compete well with the conventional one.

If the fiber chips 5 and the felt chips 6 are uniformly mixed at a predetermined ratio in advance, the supply and stirring to the sand 4 can be performed quickly and easily and can be easily applied. When the fiber chip 5 and the felt chip 6 are white or white,
It is preferable to be familiar with the sandy color of Baba without feeling uncomfortable.

Moreover, about the said felt tip 6, fully immerse in the immersion tank filled with water like FIG. 2, pressurizes with a press and compresses the felt tip 6 to about 1/3, and loosens the compressed felt tip 6 Further, the felt chip 6 repeated once more was mixed in the sand 2. As a result, it was possible to sufficiently prevent the felt tip 6 from scattering in the Baba, and the entanglement with the sand 2 was improved, which was a preferable state. Therefore, a good Baba can be formed in about 1 to several months.

In the above, fiber chips and felt chips were blended as 3 to 5: 7 to 5, but appropriate changes of about ± 5% can be made according to the season and situation based on the spirit of the present invention described above. It can be implemented as an optimal combination according to various racetracks, riding practice grounds, equestrian fields, soccer fields, baseball fields, roadside slopes, etc.
