[Industrial use]

The present invention relates to a water permeable prefabricated roadside protection block, and more particularly, to prevent damage caused by pedestrians' frequent passage of roadside trees planted on sidewalks and roadways, and prevention of spillage around the main surface planting by inflow of external rainwater. And it relates to a permeable prefabricated roadside protection block capable of providing a suitable growth environment of the roadside tree through the excellent underground inflow function, the smooth supply of external oxygen and moisture and the control of the surrounding weed growth.

[Private Technology]

The climate of Korea is gradually being subtropical due to global warming, and about 2/3 of the total annual rainfall is concentrated in June-September, causing feng shui damage such as loss of property and life.

On the contrary, in terms of re-use of rainwater, it was expected that there would be a shortage of 2 billion tons of water resources annually in 2020, due to the fact that the system was not actively established and applied.In terms of securing water resources, government agencies and local governments later reduced rainwater discharge to urban infrastructure. We believe the system will be actively applied.

Rainwater runoff reduction system can be divided into storage type and infiltration type. Storage facilities can be divided into non-regional storage facilities (reservoirs, stormwater storage facilities) and regional storage facilities (watershed storage facilities, independent storage facilities). In addition, infiltration facilities can be divided into infiltration trenches, infiltration side openings, infiltration wells, and infiltration packaging.

The roadside trees are installed around the sidewalks in the city, providing landscape richness for pedestrians and drivers, providing psychological stability, and providing functions such as air pollution and water quality purification and thermal control in some urban environments. . However, in the periphery of roadside trees, weed growth and degradation of the landscaping environment due to soil runoff during rainwater inflow and damage of pedestrians are observed.

In order to solve this problem, the conventional roadside protection plate is composed of several types of mesh castings, mesh plastics, and concrete plates of different sizes and assembly methods. It shows the destruction of roadside growth environment by soil runoff and the deterioration of landscaping at the periphery of roadside trees.

The present invention is to solve the problems as described above, the purpose of the present invention is to supply the moisture of the trees planted on the road and sidewalks, and to control the vegetation environment through the weed control, and to penetrate the ground to a certain amount of excellent By using a permeable block having a penetrating function, it is to provide a roadside protection block having an assembly function capable of changing the landscape features of the product and the size and use of the roadside tree.

The present invention includes two or more permeable blocks, in order to achieve the above object, the permeable block provides a permeable assembled roadside protection block that forms a planting space of the roadside by assembly.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a prefabricated roadside protection block manufactured using a water permeable block having excellent water permeability in order to solve the problems of the conventional roadside protection plate.
