2. Description of the Related Art A conventional method of laying natural grass on a competition field in an all-weather stadium will be described with reference to FIGS. As shown in FIG. 5, in the natural grass mat 1, a bark chip 3 is attached on the upper surface of the urethane mat 2, and the natural grass 4 is planted on the upper surface of the bark chip 3. The natural turf mat 1 is strip-shaped (about 1.2 m × 10 m) and wound in a roll in a natural turf growing yard, and is carried by a transportation means such as a truck and carried into a competition field. The rolled natural mats 1, 1, ... Are rolled by several workers and laid at a predetermined position in the competition field. Further, the adjacent natural grass mats 1 and 1 are connected to a sheet 5 of vinyl chloride or the like by an adhesive such as urethane resin.

FIG. 6 shows another conventional example, in which a competition field 12 in an all-weather stadium 11 and an outdoor natural grass raising yard 13 are installed side by side, and the natural grass raising yard 13 is used as natural grass units 14, 14 ... It is divided. The natural grass raising yard 13 and the competition field 12 are railed or grooved 15.
Are communicated with each other, and the natural turf units 14, 14 ... sequentially move in the groove 15 by a driving means (not shown) that supports the natural turf units 14, 14 ,. Forming a field.

FIG. 7 shows still another conventional example, in which a natural grass pallet 21 is formed in a gate-shaped cross section through which a driving means 22 such as a carrier truck can enter and pass, and a natural grass 23 is planted on the upper part. The operating means 22 is provided with an elevating and lowering platform 24 that can be raised and lowered by a jack or the like, and enters the lower side of the natural grass pallet 11 to raise the elevating and lowering platform 24. Then, the natural turf pallet 21 is moved to the competition field while being pushed up.

Furthermore, a coordinate signal board 25 is provided on the competition field.
The driving means 22 is provided with a coordinate signal reading device (not shown) and a driving control device 26, and the driving means 22 is driven unmanned according to a command from a central control device (not shown), and is placed on the competition field. Form a natural grass field.

[0006]

In the conventional method of forming the natural grass field on the competition field, the method of the natural grass mat using the urethane mat requires a large amount of natural grass mat. A large amount of work time and labor are required to transport and lay a natural grass mat. Further, since the natural grass mat cannot be reused, it causes a cost increase.

Then, a method in which each natural turf unit has a driving means and a method in which a natural turf pallet having a gate-shaped cross section is transported have been proposed, but in any case, there is a limit in the area of the natural turf pallet to be transported. Therefore, there are many seams in the natural grass field, and there is a problem in the finished quality of the field. In addition, a large number of large-scale devices are required for the electric trolley and the like for the traveling means and the transportation means, which is a cost problem.

Therefore, there arises a technical problem to be solved in order to expand the area of the pallet unit as much as possible and reduce the seams of the natural grass to form a natural grass field of good quality. An object of the present invention is to solve the problem.

[0009]

The present invention has been proposed in order to achieve the above-mentioned object, and is planted by a natural grass pallet in an outdoor natural grass growing yard on a competition field in an all-weather stadium. In a competition field configured to carry in natural turf, a method for forming a competition field in which the natural turf pallet is moved by a transportation vehicle using an air levitation device, and the natural turf pallet is air-supplied. Hose connection port is provided, an air pipe is embedded from the air supply hose connection port, an open air outlet is provided at the bottom of the natural turf pallet, and air such as rubber is provided around the air outlet. A natural turf pallet used in a method for forming a skirt-formed competition field, and the transportation vehicle is provided with a connecting device for connecting the natural turf pallet to supply to the natural turf pallet. There is provided a transport vehicle used in the method of forming the athletic field equipped with compressed air supply device.

[0010]

[Function] Natural turf which is carried into the competition field in the all-weather stadium is vegetated on the natural turf pallets in the outdoor natural turf growing yard juxtaposed in the all-weather stadium. A vehicle for transportation is connected to the natural turf pallet via a coupling device, an air supply hose from a compressed air supply device mounted on the vehicle for transportation and an air pipe connected to the natural turf pallet, Compressed air is supplied to an air levitation device mounted on the bottom surface of the natural grass pallet. As a result, the natural grass pallet floats slightly above the road surface by the air floating method.

Then, the natural turf pallet is pushed or pulled by the connected transportation vehicle and carried in near a predetermined position on the competition field. Then, by stopping the supply of compressed air from the compressed air supply device, the player lands on the competition field. By repeating the procedure described above, all the natural grass pallets are carried into the competition field to form a natural grass field. or,
After using the natural grass field, the natural grass pallets carried into the competition field in the same manner as described above are carried out to the outdoor natural grass growing yard, and the natural grass vegetated on the natural grass pallets is sunlight. Bred under.
