To provide a vibration resistance temporary structure which can easily remove a member for reuse, and a construction method and a removal method for the same.SOLUTION: A vibration reduction temporary structure 1 includes a reception groove 9 which is provided in a ground G and extends in a predetermined direction, and a gas layer holding member 3 which is buried in the reception groove 9, extends in a predetermined direction, and holds gas therein. The gas layer holding member 3 can inject and discharge the gas, and is expanded by injecting the gas in at least the width direction of the reception groove 9, and is shrunk by discharging the gas. The gas layer holding member 3 can be easily pulled out from the reception groove 9 without damaging the gas layer holding member 3 by discharging the gas from the gas layer holding member 3.SELECTED DRAWING: Figure 5 【課題】部材を再利用可能に容易に撤去することができる振動低減仮設構造並びにその構築方法及び撤去方法を提供する。【解決手段】振動低減仮設構造１は、地盤Ｇに設けられて所定方向に延在する受容溝９と、受容溝９内に埋設され、所定方向に延在し、内部に気体を保持した気体層保持部材３とを備える。気体層保持部材３は、気体の注入及び排出が可能であり、少なくとも受容溝９の幅方向に対して、気体を注入することにより膨らみ、気体を排出することにより萎む。気体層保持部材３から気体を排出することにより、気体層保持部材３を傷つけずに容易に受容溝９から抜き取ることができる。【選択図】図５
