LIQUEFACTION COUNTERMEASURE CONSTRUCTION METHOD AND LIQUEFACTION COUNTERMEASURE STRUCTURE
To provide an underground pipe protected against liquefaction.SOLUTION: A liquefaction countermeasure method for an underground pipe 10 having a straight pipe part 11 and a deformation part 12 to which a thrust force generated due to the difference of a flow of water flowing therein from that of the straight pipe part 11 is applied includes the injection step of injecting an injection material which causes reduction of flowability into a foundation material 15 introduced around the deformation part 12 laid in a groove formed by drilling the foundation.SELECTED DRAWING: Figure 1
【課題】液状化対策を施された埋設管を提供する。【解決手段】直管部１１と、内部を流れる水の流れが直管部１１と異なることにより生じるスラスト力が付加される変形部１２とを有する埋設管１０の液状化対策工法は、地盤を掘削して形成される溝中に敷設された変形部１２の周囲に導入された基礎材１５中に、流動性を低下させる注入材を注入する注入工程を包含する。【選択図】図１
