WEIGHT FOR DROPPED UNDERWATER WEIGHT COMPACTION METHOD, AND DROPPED UNDERWATER WEIGHT COMPACTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a weight for a dropped underwater weight compaction method and the dropped underwater weight compaction method using the weight for a compaction method of a water bottom ground executed by dropping the weight, the weight offering a high compaction effect and having a form that lands for certain on a targeted water bottom position.SOLUTION: A weight 10 for a dropped underwater weight compaction method is used in a compaction method for a water bottom ground executed by dropping the weight, and includes a bottom surface part 11 landed on the water bottom, a top surface part 12 positioned at a top edge opposite the bottom surface part, an outer peripheral part 13 constituted on a side surface between the bottom surface part and the top surface part, weight parts 17, 18 positioned inside for gaining heaviness for the weight, and a piercing part 15 piercing through the weight parts from the bottom surface part toward the top surface part, along with a rectifier 14 provided on the outer peripheral part for rectifying a relative water flow generated on the outer peripheral part when the weight is dropped into water.SELECTED DRAWING: Figure 1
【課題】水底地盤を重錘落下により締固める工法の実施に際して締め固め効果が高くかつ目標の水底位置に確実に着底できる形状を有する水中重錘落下締固め工法用重錘およびこの重錘を用いた水中重錘落下締固め工法を提供する。【解決手段】この水中重錘落下締固め工法用重錘１０は、水底地盤を重錘落下により締固める工法に用いられ、水底に着底する下面部１１と、下面部と対向するように上端に位置する上面部１２と、下面部と上面部との間の側面に構成された外周部１３と、重錘重量を得るために内部に配置された重量部１７，１８と、重量部を下面部から上面部に向けて貫通するように設けられた貫通部１５と、を備え、重錘が水中落下するとき外周部において相対的に生じる水の流れを整えるための整流部１４を外周部に設けたものである。【選択図】図１
