    • PROBLEM TO BE SOLVED: To provide a sealing structure for contaminated soil enclosure in which sealing performance is hardly broken by earthquake.SOLUTION: An earthquake-proof type contaminated soil enclosure structure is applied to a bed that includes: a hard permeability dense lower part layer L; and a permeability upper part layer Lthat includes a contaminated soil area A in a part viewed from an upper side, and has a sealing structure 2 that is formed by using an improved foundation method by injection and agitation of a solidification material into ground. The sealing structure 2 includes: an inside sealing wall part 4 that surrounds the contaminated soil area; and an outside sealing wall part 6 that surrounds a further outside of the inside sealing wall part having a constant space, and is that the inside sealing wall part and the outside sealing wall part are formed as a close wall part that attains from a top edge of the upper part layer Lto a lower part layer, earth between the inside sealing wall part and the outside sealing wall part is formed as a buffer area 10 that does not include the contaminated soil area at least at an application time of the improved foundation method, and two or more vertical long connected wall parts that connect the inside and outside both sealing wall parts are disposed.
    • 要解决的问题:提供一种密封性能几乎不会被地震破坏的污染土壤封闭物的密封结构。解决方案:将防震型污染土壤围护结构应用于床,其中包括:硬​​度密度较低的下层 升; 并且透气性上层L包括从上侧观察的部分中的污染土壤区域A,并且具有通过使固化材料注入地面而改进的地基法而形成的密封结构2。 密封结构2包括:围绕污染土壤区域的内部密封壁部分4; 以及外侧密封壁部6,其包围具有恒定间隔的内侧密封壁部的另一侧的外侧,并且内侧密封壁部和外侧密封壁部形成为从顶部边缘 上部层L到下部层之间,至少在改进的基础方法的施加时间,形成内密封壁部和外侧密封壁部之间的接地,作为不包含污染土壤面积的缓冲区域10 并且设置两个或更多个垂直长连接的壁部分,其连接密封壁部分的内部和外部。
