<p><P>PROBLEM TO BE SOLVED: To construct an intermediate revetment between a newly constructed revetment structure and an existing revetment structure before constructing a means for compensating water sealing performance between the intermediate revetment structure and the newly-constructed and existing revetment structures when a waste disposal landfill area currently used is extended to construct a new waste disposal landfill area. <P>SOLUTION: In order to partition off a sea area by erecting revetments for depositing waste in the partition, water-sealing layers 14 and 16 are formed between an intermediate revetment 13 disposed on the end portion of the existing revetment and the new and existing revetments. To grasp the states of the water-sealing layers 14 and 16, each of them is provided with pipes 21 and 21a as monitoring means. The occurrence of abnormalities in the water-sealing layer 14 or 16 is detected from information on e.g., the level of the water-sealing material in the pipe, and the water-sealing layer is immediately replenished with a water-sealing material through the pipe to restore its function as a water-sealing layer. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
