CO-SETTLEMENT PREVENTING STRUCTURE AND SETTLING METHOD OF CAISSON
To provide a co-settlement preventing structure and a settling method of a caisson which can more effectively suppress co-settlement of a peripheral ground and a nearby structure.SOLUTION: A co-settlement preventing structure comprises: a caisson skeleton 17 settling into a ground G with laminating annular bodies 11 on a foundation bottom portion 15 to form a side wall portion 12; a steel sheet pile 19 disposed at a periphery of the caisson skeleton; a ground improvement structure 25 supplied into the ground G at the periphery of the caisson skeleton and integrating the steel sheet pile with the ground; and a hanging-down portion 20 supporting the steel sheet pile so as to be movable upward.SELECTED DRAWING: Figure 1
【課題】周辺地盤や近接構造物の共下がりをより効果的に抑制することが可能な共下がり防止構造及びケーソンの沈下方法を提供する。【解決手段】基礎底部１５上に環状体１１を積層して側壁部１２を形成しつつ地盤Ｇに沈下させるケーソン躯体１７と、ケーソン躯体の周囲に配された鋼矢板１９と、ケーソン躯体の周囲の地盤Ｇ中に供給され、鋼矢板と地盤とを一体化する地盤改良体２５と、鋼矢板を上昇可能に支持する吊り下げ部２０と、を備えている。【選択図】図１
