SAND LAYING METHOD
PROBLEM TO BE SOLVED: To provide a sand laying method capable of stably and uniformly laying a sand layer over the soft seabed even when the seabed has a steep slant and the tide is strong.SOLUTION: In a sand laying method for improving the soft and inclined seabed 30 by laying material sand of a sand layer 41 over the same, the material sand is filled in a plurality of bag bodies 50, on board a working vessel 10 on the sea 31, suspended from sand pile construction hollow pipes 14 which move up and down along leaders 12. Then, the plurality of bag bodies 50 filled with the material sand are lowered from a working vessel 10 through the sand pile construction hollow pipes 14 and laid side by side with no space therebetween directly on the seabed 30.SELECTED DRAWING: Figure 8
【課題】傾斜がきつく、潮流が速い場合等でも軟弱な海底盤上に敷砂を安定して均一に敷設することができる敷砂の敷設方法を提供する。【解決手段】軟弱で傾斜した海底地盤３０上に敷砂４１の材料砂を敷設して地盤改良を行う敷砂の敷設方法において、海上３１の作業船１０にて、リーダー１２に沿って昇降する砂杭造成用中空管１４に吊した複数個の袋体５０内に材料砂をそれぞれ充填し、この複数個の材料砂を充填した袋体５０を作業船１０から砂杭造成用中空管１４を介して降下させて海底地盤３０上に隙間なく直に敷設する。【選択図】図８
