  Volcanic crushed stone, molten slag, andesite crushed stone, dredged sand, shirasu sand, shirasu balloon, volcanic ash, used permeable concrete, soil powder pavement, 22-25% of the construction thickness and construction square meters of rainwater is the amount of water storage It is. When the number of pavement construction square meters increases, it can be considered as one of the reservoirs, and it can be expected to effectively use the land.

  In the present invention, volcanic crushed stone, molten slag, andesite crushed stone, dredged sand, shirasu sand, shirasu balloon, volcanic ash, water permeability, water retention con, and soil powder pavement have the same effect as tame. It is characterized by heat island suppression and global warming suppression due to water storage effect.

  Volcanic crushed stone, molten slag, andesite crushed stone, dredged sand, shirasu sand, shirasu balloon, volcanic ash, water permeable condensate, soil powder pavement, laying roadbed, promenade, herbicidal pavement, reducing pond and ground It becomes the effective use of.

Means for solving the problem

  In the present invention, by laying and constructing water-permeable congee and soil powder pavement with volcanic crushed stone, molten slag, andesite crushed stone, dredged sand, shirasu sand, shirasu balloon, and volcanic ash, rainwater is returned to the ground to restore the groundwater, It is characterized by being able to control the flooding of the river by activating, suppressing land subsidence, permeable pavement, so that it cannot collect water, reducing underfloor inundation, and reducing the amount of drainage to the gutter.

Effect of the invention

  The present invention is a safe walking ability, non-polluting, reducing rain into the ground, unable to puddle, not slipping, suppressing sun reflection, surface temperature is 5 to 5 compared to asphalt or concrete pavement Decrease by 10 degrees. It is characterized by water retention, contributing to the activation of plants and trees, the suppression of heat islands, and the suppression of global warming.

  If the construction area of the con and soil powder pavement of the present invention is increased, the water retention and the amount of stored water will increase in proportion to that, and the economy will be greatly reduced by the drastic reduction of the side gutter construction cost due to the drastic reduction of the amount of water discharged to the gutter. It has the effect of river turbulence, underfloor inundation, and rainwater being returned to the ground, resulting in the revitalization of groundwater and the activation of plants.
