<P>PROBLEM TO BE SOLVED: To provide a cleaning structure of contaminated groundwater which can easily exchange permeable reaction walls. <P>SOLUTION: The cleaning structure of contaminated groundwater which is a structure for cleaning groundwater containing contaminated substances in situ includes a steel sheet pile 11 and an underground wall 12 which form a flow passage for guiding groundwater 6 deeply flowing in an aquifer 2 to a shallow part of the aquifer 2, and a horizontal type permeable reaction wall 13 disposed adjacent to a surface of the groundwater 2a in which the groundwater 6 is cleaned by reaction of contaminated substances 5 contained in the groundwater 6 with the wall 13 by making the groundwater 6 guided to the shallow part by the steel sheet pile 11 and the underground wall 12 to permeate through the wall 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
