Abstract
At a location where unevenness 1000 is present, the condition of a seabed 200 is investigated in advance to examine the respective numbers of large filter units 51 and small filter units 52 to be used, and the position where the large filter units 51 and the small filter units 52 are to be installed. Based on the investigation result, the small filter units 52 are installed on the bottom of the unevenness 1000. The large filter units 51 are installed on the upper surface formed by the installed small filter units 52, and are leveled so that the upper surface formed by the installed large filter units 51 becomes flush with the seabed 200.
