GROUND VIBRATION REDUCTION DEVICE
To provide a ground vibration reduction device capable of preventing an excessive increase of cost for temporary construction as large-depth drilling, earth retaining, or opening closing is not necessary and back filling or earth retention removal at the end of construction is not necessary, and surely reducing construction vibration without needing much cost for construction or removal of a wall body and without altering a ground structure or affecting a surrounding ground by inclination or the like.SOLUTION: This ground vibration reduction device installed between a vibration generation source and a vibration reception area 9 which is provided on the extension line of the vibration generation source and through which vibration is transmitted comprises: a bottom board 4 laid on the ground between the vibration generation source and the vibration reception area 9 provided on the extension line of the vibration generation source; and a vibration prevention loaded article 5 placed on the bottom board 4 to reduce vibration at the vibration reception area 9.SELECTED DRAWING: Figure 1
【課題】大深度の掘削や土留および開口部閉塞を必要とせず、また工事終了時の埋戻しや土留撤去を必要としないので工事仮設のコストが多大とならず、壁体の施工や撤去に多大のコストを必要とせず、地盤構造の改変をきたし、周辺地盤に傾斜等の影響を与えることがなく、確実に工事振動などを低減できる地盤振動低減装置を提供する。【解決手段】振動発生源と、該振動発生源の延長線上に設けられた振動が伝達する受振部エリア９との間に設置される地盤振動低減装置であり、該地盤振動低減装置は、前記振動発生源と、振動発生源の延長線上に設けられた受振部エリア９との間の地盤上に敷設される敷板４と、敷板４上に載置され、受振部エリア９での振動を低減する防振用積載物５とを有することを特徴とする。【選択図】図１
