UNDERGROUND BURIED OBJECT FLOATING PREVENTION METHOD AND UNDERGROUND BURIED OBJECT FLOATING PREVENTION STRUCTURE
To provide an underground buried object floating prevention method and an underground buried object floating prevention structure which are excellent in economy and workability.SOLUTION: An underground buried object floating prevention method comprises steps of penetrating a casing pipe 40 from above an underground buried object 20 to a predetermined depth, injecting a consolidated body from the tip of the casing pipe 40 or injecting a consolidated body above the underground buried object 20 before the casing pipe 40 penetrates to form a support layer 10, putting a drain material into the casing pipe 40, and pulling out the casing pipe 40 while compacting the drain material in the casing pipe to form a drain column 12.SELECTED DRAWING: Figure 4
【課題】経済性及び施工性に優れた地中埋設物の浮上防止工法及び地中埋設物の浮上防止構造の提供。【解決手段】地中埋設物の浮上防止工法は、地中埋設物２０の上方から、所定深さまで、ケーシングパイプ４０を貫入するステップと、前記ケーシングパイプ４０の先端部から固結体を注入し、又はケーシングパイプ４０の貫入前に地中埋設物２０の上方に固結体を注入し、支持層１０を形成するステップと、前記ケーシングパイプ４０内に、ドレーン材を投入するステップと、前記ケーシングパイプ内の前記ドレーン材を締固めながら、前記ケーシングパイプ４０を引き抜いて、ドレーン柱１２を形成するステップと、を含む。【選択図】図４
