Description

Flood prevention block

The present invention relates to an overflow prevention block for preventing water flowing from a ground surface of a sidewalk block in a rainy season from entering a commercial street or a house.

The walkway block is mainly used by passengers to arrange blocks of a certain size and shape to prevent the occurrence of dust and so on. The rainwater is drained to the surface of the ground to generate groundwater and natural purification to preserve the ecological environment. Lt; / RTI >

Typically, a sidewalk block is installed between a driveway and a residential area or a residential area. More specifically, as shown in Fig. 1, there are provided a road A1, a drainage hole A2 on the roadside, a boundary block 20 which is installed higher than the drainage port and separates the roadway from the roadway, The sidewalk block 10 is installed.

Generally, when raining, in the event of heavy exaggeration, the storm will be absorbed into the ground of the sidewalk block and return to nature. This weakly makes it difficult for pedestrians in India to walk, and seriously floods in nearby shopping malls or houses, causing flood damage.

As an alternative to prevent this, it is possible to replace the sidewalk block with a permeable block that is easier to pitch on the ground. However, replacing the sidewalk block with a pitcher block improves the ability to drain the stormwater to the ground, but if the initial stormwater volume increases, the flood can not be prevented if it exceeds the limit of the water that can be absorbed. Also, the permeable block is manufactured in consideration of the characteristics of the permeable water, so that it is difficult to maintain due to frequent damage due to weak strength, and there is a problem that the surface wear is severe.

Another alternative is the application of Registration No. 10-0730723. Japanese Patent Application Laid-Open No. 10-0730723 proposes a drainage passage formed in a boundary block so that water coming out of the sidewalk block can be drained to a drainage port. However, because the pre-registered patent only drains the overflowing water, the blocks in India are already water-rich, making it difficult for India to walk, as well as preventing the block's surface from overflowing into commercial or residential areas, There is no problem.

Another alternative is the application of Registration No. 10-1111185. However, the water discharged to the ground through the sidewalk block flows into the water-permeable hole formed at the lower side of one side of the boundary block in the shape of a drainage port to drain the water . However, as described above, since the target is not water coming into the sidewalk block as described above, it is configured to remove the contaminants to the water flowing into the drain port from the roadway, so that it is not possible to drain the water from the sidewalk block. On the other hand, when the water drained to the ground flows into the water hole, foreign substances such as sand can flow into the water hole, and the drainage passage is blocked.
