Floor block structure with excellent water permeability {FLOOR BLOCK STRUCTURE HAVING ENHANCED WATER PERMEABILITY}

The present invention relates to a floor block structure having excellent water permeability. In more detail, the present invention relates to a floor block structure having excellent water permeability by forming a space in which foreign substances such as sand can be filled on the side and the bottom of the sidewalk block.

In recent years, in road development and various landscaping works related thereto, various road pavement materials having permeability have appeared as one method for preserving an eco-friendly ecosystem by reducing rainwater to nature.

Among them, the need for a floor block structure capable of beautifully creating the surrounding vegetation environment is emerging for the purpose of placing importance on the natural landscape.

Conventional floor structures used for pavements such as sidewalks, bicycle paths, and park trails do not sufficiently penetrate rainwater, and thus it is difficult to sufficiently utilize water resources such as rainwater.

As a prior art for solving this problem, the Korean Utility Model Registration No. 20-0245754 [Document 1] discloses a technical configuration for forming a groove 2 on the side of the block 1 for a sidewalk.

The block 1 for pedestrian crossing according to the document 1 has a problem in that the groove 2 is clogged by foreign substances such as sand, and there is a high possibility that rainwater or the like cannot sufficiently penetrate.

As another prior art, the Korean Utility Model Registration No. 20-0381399 [Document 2] discloses a technical configuration of forming a protruding surface 120 and a spacing support 130 on the side of the permeable sidewalk block 100. .

In this document 2, rainwater may flow into the space provided between the permeable sidewalk blocks 100.

However, in Document 2, there is a problem that the spacing between the water permeable sidewalk blocks 100 may be excessively large for sufficient penetration of rainwater, which may be disadvantageous in terms of design, and may be disadvantageous in terms of stability.

When the second area AR2 of FIG. 7 is enlarged, as shown in FIG. 8, the fourth lower groove portion 200d is formed in the second side groove portion 100f and the fourth side surface SP4 formed on the third side surface SP3. It can be seen that the first side groove portion 100g is commonly connected.
