Description

  The present invention relates to a water-permeable pavement method capable of infiltrating rainwater into the ground using a natural stone plate that is extremely difficult to form fine water-permeable holes that allow rainwater to pass through, and a natural stone plate used in the water-permeable pavement method. And a pavement reinforcing plate.

Torrential rain caused by the heat island phenomenon has been steadily increasing with global warming, and flooding of urban rivers has threatened a safe and comfortable living environment.
As a measure to prevent the flooding of this urban river, water permeability of the pavement is being promoted. Needless to say, the water permeability of the pavement temporarily stores rainwater in the pavement by permeating the rainwater into the ground, preventing it from concentrating into the river and thus preventing the flooding of urban rivers. It is something to try.

  There are asphalt pavement, concrete pavement, concrete block pavement, natural stone flat pavement, and brick pavement as the pavement forms that make up the city. Because of this, natural stone slab pavement has not yet been permeable.
