The present invention relates to a structure constituting the floor surface on which the artificial turf is installed, in particular, on the base layer formed on the ground to form a permeable layer mixed with silicic acid and environmentally friendly char and aggregate, the aggregate layer and cement on the top It relates to an environment-friendly water-permeable artificial turf structure formed of a porous body having a good water permeability by forming a urethane resin layer with a mixed adhesive.

Bases such as sports grounds and tennis courts where artificial turf is installed are mostly made of concrete structures, and an elastic rubber plate is installed on the upper surface of the concrete to absorb shocks.

In general, groundwater should be infiltrated by rainwater in normal times to preserve groundwater and maintain a constant strength of the ground.

However, the artificial turf ground formed by the concrete base prevents rainwater from penetrating into the ground naturally, so the groundwater is drastically reduced, so that the ground subsides and changes the ecological environment of the underground organisms.

In addition, if there is heavy rain during a game in an outdoor stadium where artificial turf is installed, it causes the game not to be drained quickly, and it is a cause of impediment to the game. The floor surface remains moist for a long time, providing a good environment for a large number of pests and bacteria.

In the playground where artificial turf is installed, rainwater can naturally penetrate into the ground while maintaining proper humidity at all times, and a pavement method capable of performing a purification function on its own can be solved.

You can think of silicic acid and charcoal as components of a package that can be used as a way to improve soil quality and purify rainwater that penetrates underground.

Silicic acid is weak alkaline and improves soil quality. Charcoal emits far-infrared rays, which are well known. It is beneficial to the human body, and it is used in various ways besides energy sources that require heat due to its filtration, purification and deodorization functions. It is used as a soil improving agent by preventing acidification and supplying beneficial minerals to plants to enhance the intellect.

However, charcoal, by itself, is poor in durability and strength and therefore cannot be used as a main material for packages.

Although charcoal is problematic in terms of durability and strength, it is naturally friendly, and as is well known, it is chemically stable in addition to the advantages of emitting far-infrared rays which is beneficial to the human body. It is possible to filter and purify the rainwater that has soaked in it, so that if the overall strength problem is compensated for by the other materials constituting the package, the artificial turf playground can achieve the desired purpose because it can be flexible to compressive and bending stresses. It may be possible to provide a packaging for the product.

It is another object of the present invention to form a urethane resin layer fixed with a permeable layer and a cement adhesive on top of the silicic acid and charcoal layer installed on the ground layer of the ground, and has durability, compressive strength, bending strength and cushioning action while maintaining natural characteristics and advantages. It is to provide an eco-friendly permeable artificial turf structure that can prevent cracking.

Another object of the present invention is to form a permeable layer and a urethane resin layer on top of the silicic acid and charcoal layer laid on the ground layer of the ground to suppress the infestation of pests or bacteria in the base of the playground by filtration and purification by the silicic acid and the char layer It is to provide an environmentally friendly permeable artificial grass structure.
