COMPOSITE TYPE LIQUEFACTION GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a composite type liquefaction ground improvement method capable of preventing loss of the dense-effect of dynamic injection out of an injection range.SOLUTION: The composite type liquefaction ground improvement method prevents loss of the dense-effect of dynamic injection out of an injection range by constructing or disposing a wall for restricting displacement in the vicinity of an injection object range before carrying out the ground improvement. The wall for restricting displacement is constructed or disposed in an upper part of the injection object range in a manner of chemical liquid injection.SELECTED DRAWING: Figure 1
【課題】動的注入の密実効果を注入範囲外に逃さない複合式脈状地盤改良工法を提供する。【解決手段】複合式脈状地盤改良工法において、地盤改良前に注入対象範囲の近傍に変位を拘束する壁を造成又は設置することにより、動的注入の密実効果を注入範囲外に逃さないようにする複合式脈状地盤改良工法であって、前記注入対象範囲の上部に薬液注入工による上部変位を拘束する壁を造成又は設置する。【選択図】 図１
