STORAGE STRUCTURE OF HEAVY METAL POLLUTED SOIL
To effectively enhance contact frequency between an adsorbent and a heavy metal in an adsorption layer while making reworkability easy.SOLUTION: A storage structure has a banking body part 1A in which at least a water shielding layer 2 and a polluted soil layer 4 containing a heavy metal are laminated from a foundation side G, and a leachate flowing down on an upper surface of the water shielding layer 3 from the polluted soil layer 4 is introduced to a side surface 2A of the water shielding layer 2, and an adsorption layer 6 which is arranged in contact with at least the side surface 2A of the water shielding layer 2, and in which the leachate leaching from the banking body part 1A is distributed and an adsorbent adsorbing the heavy metal contained in the leachate is mixed.SELECTED DRAWING: Figure 1
【課題】再施工性を容易にしつつ、吸着層における吸着材と重金属との接触頻度を効果的に高める。【解決手段】地盤側Ｇから少なくとも遮水層２及び、重金属を含む汚染土層４が積層され、汚染土層４から遮水層３の上面に流下する浸出水が遮水層２の側面２Ａに向けて案内される盛土本体部１Ａと、少なくとも遮水層２の側面２Ａに接して設けられ、盛土本体部１Ａから浸出する浸出水を流通させると共に、浸出水に含まれる重金属を吸着する吸着材が混合された吸着層６とを備えた。【選択図】図１
