SANDY SOIL COMPACTION METHOD
To provide a sandy soil compaction method capable of further improving compaction efficiency at low cost.SOLUTION: A sandy soil compaction method for compacting sandy soil 1 by vibrating a rod 5 comprises the steps of driving the rod 5 into shallow layer portion 2 of the sandy soil 1 to penetrate it to a predetermined depth, then pulling out the rod 5 by a predetermined length to apply vibration and impact to a tip portion 5a of the rod 5 to drop sediment 1a of the surrounding ground into a hollow portion K formed around it, and then redoing the rod 5 to compact the shallow layer portion 2.SELECTED DRAWING: Figure 1
【課題】低コストで締め固め効率をより一段と向上させることができる砂質地盤締固め工法を提供する。【解決手段】砂質地盤１をロッド５の振動により締め固める砂質地盤締固め工法であって、砂質地盤１の浅層部２中に所定深度までロッド５を打ち込んで貫入し、次に、ロッド５を所定長さ引き抜いて該ロッド５の先端部５ａに振動・衝撃を加えてその周囲にできた空洞部Ｋに周辺地盤の土砂１ａを落とし込み、次に、ロッド５を打ち戻して浅層部２を締め固める。【選択図】図１
