Description

[0001] The present invention relates to a water permeable sidewall block using an eco-friendly mixed material and a water treatment system having the water permeable sidewall block,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water permeable sidewalk block using an environmentally friendly mixed material and a drainage treatment system having the waterproof sidewall block. More particularly, the present invention relates to a waterproof sidewall block comprising a surface layer formed of synthetic wood or crushed stone aggregate, Wherein a through hole is formed so that a coupling member having a penetrating hole formed at each central portion of the surface layer block and the base layer block can be inserted and the surface layer block and the base layer block can be separated from each other, Permeable pavement block using an eco-friendly mixed material capable of providing a continuous water permeability function because it can be separated and combined and reused when the penetrant is clogged.

Generally, the sidewalk block is mainly used for the sidewalk and the sidewalk pavement. However, since the ride quality of the sidewalk is poor, it is hardly used for the sidewalks and because of various colors and shapes of the blocks, the sidewalks, It is mainly used for packaging.

Since most of these sidewalk blocks are formed as impervious pavement surfaces, drainage on the surface of the sidewalk pavement block is not smooth and causes imhyeonhyeon, resulting in inconvenience of passage. Rainwater in the sidewalk block can not flow into the underground soil It is introduced into the roadway and combined with the rainwater in the roadway, which increases the inconvenience through the vehicle and increases the rainwater conveyance ability of the rainwater receiver installed at the edge of the roadway.

Thus, in the conventional sidewalk block, water is not passed through as in the case of the general sidewalk block. However, in recent years, a permeable sidewalk block has been developed so that water is supplied to the ground through the lower portion.

In addition, there are various attempts to prevent the heat island phenomenon caused by rapid urban development, which can cause tropical nights and increase health damage, as well as cause urban pollution and air pollution. .

However, since the sidewalk block according to the prior art is made by mixing gravel and the like in most cement, there is a problem that it is difficult to maintain the permeability when foreign matter is caught between gravel gaps over time, and it is also difficult to prevent heat island phenomenon.

In addition, there is a problem in that it is easily cracked or damaged due to use for a long time or external impact, and dust is generated due to wear of the surface, thereby causing environmental pollution.

Therefore, there is a desperate need for a practical and applicable technology suitable for preventing environmental pollution, sustaining permeability, and preventing heat island phenomenon.
