SETTLEMENT REPAIRING METHOD OF ARTIFICIAL DRY BEACH AND ARTIFICIAL DRY BEACH STRUCTURE WITH SETTLEMENT REPAIRING FUNCTION

PROBLEM TO BE SOLVED: To efficiently repair by raising a level of a settled artificial dry beach, by using waste such as dredged earth troubled with treatment, without using new good-quality sand. SOLUTION: When preparing the artificial dry beach for arranging a covering sand layer 5 on a reclaimed sediment layer 4 prepared by properly banking up on a weak clay layer 3 of the water bottom ground, after preparing the reclaimed sediment layer 4, a bag-like sheet 10 capable of filling an infilling material such as sediment between doubly superposed obverse-reverse sheet-like materials, is laid on its upper surface. The covering sand layer 5 is laid on its upper surface, and when settlement is caused, the covering sand layer 5 is raised in a level by injecting the infilling material into the bag-like sheet 10.
