UNDERWATER COMPACTION METHOD
PROBLEM TO BE SOLVED: To provide an underwater compaction method which can impart a necessary compaction degree surely over the whole area of a granular material layer formed by dropped granular materials even when a region in the water to which granular materials are dropped is a narrow region such as adjacent to a structure.SOLUTION: Granular materials are dropped to a region in the water to which granular materials are dropped and which is adjacent to a structure, so as to form a granular material layer, and a vibration rod is inserted in a close part adjacent to the structure in the granular material layer and is vibrated so that the granular material layer is compacted. After this, a vibro tamper is pressed to the surface of a general part excluding the close part in the granular material layer and is vibrated so as to compact the granular material layer again.SELECTED DRAWING: Figure 3
【課題】粒状体を投下する水中の投下領域が、構造物と隣接するような狭隘な領域であっても、投下した粒状体にて形成された粒状体層全域にわたって、必要な締固め度を確実に付与することの可能な、水中締固め工法を提供する。【解決手段】構造物に隣接する水中の投下領域に粒状体を投下して、粒状体層を形成し、該粒状体層における前記構造物に近接する近接部に、振動ロッドを挿入するとともに起振させ、該粒状体層を締固めた後、該粒状体層における前記近接部を除く一般部の表面に、バイブロタンパーを押しあてるとともに起振させ、粒状体層を再度締固める。【選択図】図３
