Abstract

PROBLEM TO BE SOLVED: To prevent soil contamination by adsorbing and fixing heavy metals dissolved or suspended in rain water fallen on the ground. SOLUTION: A crushed stone layer 3 is laid down around a penetrating pipe 1 which forms penetrating holes 1a on the peripheral wall and flows out water during the distribution of water and a penetrating well 2 which stores water and flows out the stored water. The crushed stone layer 3 is covered with a permeable sheet 4 which has permeability and contains the crushed bodies of minute radioactive rare earth mineral (mineral containing natural thorium or natural uranium), baked bodies formed by mixing the powder of minute radioactive rare earth mineral with ceramic material and baked, and crushed bodies formed by crushing the baked bodies. Rain water flowed out from the penetrating pipe 1 and penetrating well 2 passes through the crushed stone layer 3 and is brought in contact with the permeable sheet 4. Thus hydroxide ions generate and the hydroxide ions adsorb and fix the ions of the heavy metals.

A crushed stone element is laid around the infiltration pipe with a predetermined thickness, and the crushed stone element is seated with a sheet element. It is configured so as to be wrapped so that water flowing or stored in the infiltration tube can penetrate into the ground through the infiltration hole, the crushed stone element and the sheet element. In particular, since the crushed stone element is wrapped in the sheet element, the surrounding earth and sand do not enter between the crushed stone elements, and a good infiltration action can be maintained.

A crushed body obtained by crushing a trace radioactive rare earth ore or a powder obtained by crushing a trace radioactive rare earth ore that generates water-soluble and negative ion hydroxide ions is mixed with a ceramic raw material and fired. Because it is covered with a permeable sheet containing crushed crushed material, even if heavy metal is dissolved in rainwater falling on the ground surface, it can adsorb and fix the heavy metal in which hydroxyl ions are dissolved . For this reason, there is no possibility of contaminating the soil in which water has penetrated.

Further, a crushed stone layer is laid around the permeation tube and the permeation well, and the crushed stone layer is crushed by crushing a trace amount of radioactive rare earth ore which has water permeability and generates hydroxyl ions as negative ions. Alternatively, even when the powder obtained by crushing a trace amount of radioactive rare earth ore is mixed with a ceramic raw material and fired, or when the fired body is covered with a water-permeable sheet containing the crushed body, the hydroxide ions are dissolved. It can adsorb and fix heavy metals. For this reason,
There is no risk of contaminating the soil in which water has penetrated.
