PROBLEM TO BE SOLVED: To keep the performance of an impervious wall proper by infilling an impervious material into a joint portion in which steel sheet piles are erected in line, when controlled-type revetment is constructed by erecting the impervious wall. SOLUTION: When the controlled-type revetment is constructed, the impervious material is infilled into an internal space 21 in a connecting portion between sheet pile walls 15 in which the steel sheet piles 20 are erected in line, so that imperviousness to water can be maintained in the joint portion. When the impervious material is infilled, a perforated pipe 22 is prearranged, so that impurities such as water can be moved upward from below, as the impervious material is infilled. Thus, the water and the like are prevented from remaining by being sealed in the lower portion of the impervious material and an impervious material layer. COPYRIGHT: (C)2008,JPO&INPIT
