Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to the basic structure of sports stadiums using artificial turf, particularly golf course greens.

(Prior art) Recently, among the artificial lawns in which pile fibers are planted on a base fabric that has corrosion resistance, one in which the pile fibers of the artificial lawn are coated with sand is said to be similar to natural grass. It has been attracting attention and is being used in various competition facilities, but attempts to use artificial turf as golf course greens are attracting particular attention.

(Problems to be Solved by the Invention) Up until now, when laying an artificial lawn, it has been either laid directly on a soil base, or on a base compacted using crushed stone, and then covered with asphalt mixture, concrete, soil cement, etc. They used this as a base to lay artificial turf on top.

However, when artificial turf is laid directly on the soil, there are drawbacks such as sloping land caused by frost heaving in winter and water puddles due to poor drainage.

In addition, when using a gold base such as asphalt mixture or concrete, the base is concrete or asphalt itself, so it is hard and the ball has a large rebound, and the ball rolls too much. It has been pointed out that it puts a heavy burden on the human body, including the lower back, and has a negative impact on the player's condition.

Therefore, the present inventors have studied the basic structure of an artificial lawn that can solve the above-mentioned drawbacks, and have arrived at the present invention.

(Means for Solving the Problems) That is, the present invention is characterized in that a cushion Mf:Rn of rubber or rubber asphalt is spread and laid on top of a foundation made of crushed stone that has been completely compacted. This is the basic structure of the artificial grass green.

The configuration of the present invention will be explained in detail below.

The crushed stone layer (3) that forms the basis of the artificial lawn (1) in the present invention
) is 10~30≠, spread it out to a thickness of about 5~10Qm, and thoroughly compact it with a vibrating plate of about 1rO~/00Kg.

After that, a rubber mat with a thickness of about 3 to 1 cm or a rubber asphalt pavement (2) with a similar thickness is completely formed. There are many types of artificial grass, but among them, the so-called sand-filled artificial grass, which is fixed only by its own weight without using adhesives, blends well with the substrate and is easy to work with. Are suitable.

(Effects of the Invention) As described above, the present invention has the following effects in comparison with the conventional artificial lawn laying method.

That is, 1. When the conventional foundation was laid directly on soil, there were disadvantages such as the formation of shin land due to frost heaving during the winter and the formation of water puddles due to poor drainage. Does rubber or rubber-containing diaasphalt of 3~j; crn play a waterproof role on top of the ? As a result, an impermeable layer is formed, and capillary water from underground can be traced through the crushed stone layer, making it possible to prevent frost heave.

In addition, when using conventional asphalt mixtures, cement, cement, etc. as a base, they are hard, resulting in high ball bounce, legs that roll over 9, and a heavy burden on the human body including the lower back, resulting in health issues. However, since the rubber or rubber asphalt layer has a cushioning property, the ball bounces and rolls appropriately, and the condition is extremely close to that of natural grass, and it has no adverse effects on the human body. This has the effect of reducing the
