METHOD OF PREVENTING FLOATING OF UNDERGROUND STRUCTURE
PROBLEM TO BE SOLVED: To prevent floating of an underground structure further reliably while reducing labor and cost.SOLUTION: An existing underground structure 10 has a liquid in the interior 18 and has a bottom plate 13. In a discharging step, the liquid is discharged from the interior 18, in drilling step, a drilling part 31 is drilled in such a way that the lower end passes through the bottom plate 13 and reaches a ground 1 below the underground structure 10, in an injection step, a modifier 50 which solidifies after injection into the ground 1 from the drilling part 31 is injected, in an anchor setting step, a nut type anchor 60a etc. are installed from the drilling part 31 to the ground 1 into which the modifier 50 is injected, and in a connecting step, the nut type anchor 60a etc. and the underground structure 10 are connected. Therefore, the underground structure 10 is restrained by the ground 1 modified by the nut type anchor 60a, so that floating of the underground structure 10 is prevented. Therefore, it is possible to further reliably prevent the floating of the underground structure while reducing labor and cost.SELECTED DRAWING: Figure 10
【課題】労力及び費用を低減しつつ、より確実に地中構造物の浮き上がりを防止する。【解決手段】内部１８に液体が存在し、底版１３と有する既設の地中構造物１０に対し、排出工程で、液体が内部１８から排出され、削孔工程で、底版１３を貫通しつつ下端が地中構造物１０の下方の地盤１に到るような削孔部３１が削孔され、注入工程で、削孔部３１から地盤１に注入後に固化する改質材５０が注入され、アンカー設置工程で、改質材５０を注入された地盤１に対して削孔部３１からナット型アンカー６０ａ等が設置され、連結工程で、ナット型アンカー６０ａ等と地中構造物１０とが連結される。よって、地中構造物１０はナット型アンカー６０ａにより改質された地盤１に拘束されるため、地中構造物１０の浮き上がりが防止される。そのため、労力及び費用を低減しつつ、より確実に地中構造物の浮き上がりを防止することができる。【選択図】図１０
