FLOTATION PREVENTATIVE METHOD FOR UNDERGROUND STRUCTURE
To provide a floating preventative method for an underground structure preventing the underground structure such as a rainwater storage tank in a simply configuration.SOLUTION: A floating preventative method for an underground structure comprises steps of: installing an underground structure 1 in a space formed by excavating the ground; refilling surroundings of the underground structure; installing a sheet member 5 so as not only to abut on an upper surface 1b of the underground structure but to protrude in a horizontal direction around the upper surface; and refilling the excavated space by covering sediment on the sheet member. It may comprises steps of: installing sheet members 6, 8 so as not only to cover the underground structure but to protrude in the horizontal direction around a bottom part of the underground structure; and placing members comprising materials with specific gravity larger than that of sediment, allowing crushed rocks 7, 9 with the specific gravity larger than that of the sediment used for refill.SELECTED DRAWING: Figure 1
【課題】簡易な構成で、雨水貯留槽等の地下構造物の浮き上がりを効果的に防止する。【解決手段】地面を掘削した空間内に地下構造物１を設置し、地下構造物の周囲を埋め戻し、地下構造物の上面１ｂに当接すると共に、上面の周囲に水平方向に張り出すようにシート部材５を敷設し、シート部材の上に土砂を被せて掘削した空間を埋め戻す地下構造物の浮上防止方法。地下構造物を覆うと共に、地下構造物の底部の周囲に水平方向に張り出すようにシート部材６、８を敷設し、張り出し部に埋め戻す土砂よりも比重の大きい材料からなる部材を配置してもよく、埋め戻す土砂よりも比重の大きい材料を砕石７、９とすることができる。【選択図】図１
